<p><strong>UPDATE: Thanks everyone - 10 participants in just a few hours! The study&#8217;s closed now, and I&#8217;m just about to draw who&#8217;s won the book&#8230;</strong></p>
<p>If you&#8217;ve got a few minutes spare, are interested in the <a href="http://designwithintent.co.uk">Design with Intent techniques</a>, and fancy having a 1/10 chance of winning a brand-new copy of <a href="http://www.csiss.org/classics/content/13"><em>The Hidden Dimension</em></a>, Edward T Hall&#8217;s classic 1966 work on <a href="http://en.wikipedia.org/wiki/Proxemics">proxemics</a> (very worthwhile reading if you&#8217;re involved in any way with the design of environments, either architecturally or in an interaction design sense), then please do have a go at <a href="http://websort.net/s/84C766/" target="_blank"><strong>this quick card-sorting exercise</strong></a> [now closed].</p>
<p>It makes use of the <a href="http://architectures.danlockton.co.uk/2009/07/02/modelling-users-pinballs-shortcuts-and-thoughtfulness/">pinball / shortcut / thoughtful user models I introduced in the last post</a>, so it would probably make sense to have that page open alongside the exercise. The DwI techniques will be presented to you distinct from the &#8216;lenses&#8217; (Errorproofing, Cognitive etc) so don&#8217;t worry about them.</p>
<p>The free <a href="http://websort.net">WebSort</a> account I&#8217;m using for this only allows 10 participants, so be quick and get a chance of winning the book! Once 10 people have done it, I&#8217;ll draw one of the participants out of some kind of hat or bucket and email you to get your postal address.</p>
<p>The purpose here (a <em>closed card-sort</em>, to use <a href="http://www.rosenfeldmedia.com/books/cardsorting/">Donna Spencer</a>&#8217;s terminology) is, basically, to find out whether the pinball / shortcut / thoughtful models allow the DwI techniques to be assigned to particular ways of thinking about users - that make sense to a reasonable proportion of designers. There&#8217;s no right or wrong answer, but if 80% of you tell me that one technique seems to fit well with one model, while for another there&#8217;s no agreement at all, then that&#8217;s useful for me to know in developing the method.</p>
<p>Thanks for your help!</p>

			<content:encoded><![CDATA[<p>The different approaches to influencing people&#8217;s behaviour outlined in the <a href="http://designwithintent.co.uk">Design with Intent toolkit</a> are pretty diverse. Working out how to apply them to your design problem, and when they might be useful, probably requires you, as a designer, to think of &#8220;the user&#8221; or &#8220;users&#8221; in a number of different ways in relation to the behaviour you&#8217;re trying to influence. I&#8217;ve thought about this a bit, and reckon there are maybe three main ways of thinking about <em>users</em> - models, if you like - that are relevant here. (These are distinct from the <a href="http://architectures.danlockton.co.uk/2009/04/06/what-sort-of-behaviour/">enabling / motivating / constraining</a> idea.)</p>
<p><img class="floatleft" src="http://danlockton.co.uk/research/images/pinball_ktpupp.jpg"/><a name="pinball"></a><strong>The &#8216;Pinball&#8217; User</strong></p>
<p>In this case, you think of users as, pretty much, very simple components of your system, to be shunted and pushed and pulled around by what you design, whether it&#8217;s physical or digital architecture. This view basically doesn&#8217;t assume that the user thinks at all, beyond basic reflex responses: the user&#8217;s a pinball (maybe a slightly spongey one) pushed and pulled this way and that, but with no requirement for understanding coming from within [1,2].</p>
<p>While things like <a href="http://architectures.danlockton.co.uk/category/benches/">deliberately uncomfortable benches</a> or <a href="http://architectures.danlockton.co.uk/2008/02/13/mosquito-controversy-goes-high-profile/">the Mosquito</a> act against the Pinball User - effectively treating users like animals - this view need not <em>always</em> take such a negative approach - lots of safety systems, even down to making sure <a href="http://mmpp.wikispaces.com/EX5-3">different shape connectors</a> are used on medical equipment to prevent mistaken connections, don&#8217;t mind whether the user understands what&#8217;s going on or not: it&#8217;s in everyone&#8217;s interests to influence behaviour on the most basic level possible, without requiring thought.</p>
<p><img class="floatright" src="http://danlockton.co.uk/research/images/shortcut_alanstanton.jpg"/><a name="shortcut"></a><strong>The &#8216;Shortcut&#8217; User</strong></p>
<p>Here, you think of users as being primarily interested in getting things done in the easiest way possible, with the least effort. So you assume that they&#8217;ll take shortcuts [3], or make decisions based on intuitive judgements (Is this like something I&#8217;ve used before? How does everyone else use this? I expect this does what it looks like it does), habits, and recognising simple patterns that influence how they behave. </p>
<p>The Shortcut User is assumed not to want to think too much about what&#8217;s going on behind the scenes, beyond getting things done. He or she&#8217;s not always thinking about the <em>best</em> way of doing things, but a way that seems to work [4]. If systems are designed well to accommodate this, they can feel very easy to use, intuitively usable, and influence user behaviour through these kinds of shortcut mechanisms rather than anything deeper [5]. But there&#8217;s clearly potential for manipulation, or leading users into behaviour they wouldn&#8217;t choose for themselves if they weren&#8217;t taking the shortcuts.</p>
<p><img class="floatleft" src="http://danlockton.co.uk/research/images/thoughtful_esthr.jpg"/><a name="thoughtful"></a><strong>The &#8216;Thoughtful&#8217; User</strong></p>
<p>Thoughtful Users are assumed to think about what they are doing, and why, analytically: open to being persuaded through reasoned arguments [6] about why some behaviours are better than others, maybe motivating them to change their attitudes about a subject as a precursor to changing their behaviour mindfully. If you think of your users as being Thoughtful, you will probably be presenting them with <a href="http://infosthetics.com/">information</a> and feedback which allows them to explore the implications of what they&#8217;re doing, and understand the world around them better.</p>
<p>Most of us like to model ourselves as Thoughtful Users, even though we know we don&#8217;t always fit the model. It&#8217;s probably the same with most people: so knowing when it&#8217;s appropriate to assume that users are being mindful of their behaviour, and when they&#8217;re not, will be important for the &#8217;success&#8217; of a design.</p>
<p>_______________________________________</p>
<p>Of course there are many other ways you can model the user. But these seem like they might be useful ways of thinking, and of classifying the actual <a href="http://bura.brunel.ac.uk/bitstream/2438/3258/1/DwI_Toolkit_v09_linked_eBook_with_indiv_pages.pdf">design techniques for influencing behaviour</a> [PDF] according to what assumptions they make about users. I will try to test their validity / usefulness as part of my trials.</p>
<p>See <a href="http://architectures.danlockton.co.uk/2009/07/02/sort-some-cards-and-win-a-copy-of-the-hidden-dimension/">the next post</a> for how you can get involved with that&#8230;</p>
<p><h7><strong>Note:</strong><br />
From an academic psychology (or behavioural economics) point of view, the boundaries between these models of the user are maybe too blurry. Shortcut User is assumed to be pretty much like a <a href="http://www.scientificamerican.com/article.cfm?id=of-two-minds-when-making">System 1 thinker</a>, while Thoughtful User is System 2. Straying inadvisedly into areas I know little about, Pinball User may well be assumed to be a user only using the <a href="http://en.wikipedia.org/wiki/Reptilian_complex">R-complex</a>, though I&#8217;m not sure this fits especially well. But if the distinctions are useful to designers, in the context of actually developing products and services, that (to be honest) is what matters from my point of view.</h7></p>
<p><h7>To develop the three models described above, I was inspired by <a href="http://mags.acm.org/interactions/20090102/?pg=71">this <em>Interactions</em> article</a> (also <a href="http://www.dubberly.com/articles/what-is-interaction.html">here</a>) by <a href="http://www.dubberly.com/about">Hugh Dubberly</a>, <a href="http://pangaro.com/">Paul Pangaro</a> and <a href="http://haque.co.uk/">Usman Haque</a>, which draws on some of Kenneth Boulding&#8217;s <a href="http://iscepublishing.com/ECO/ECO_other/Issue_6_1-2_18_CP.pdf">General Systems Theory [PDF]</a> to characterise a range of ordered system &#8216;combinations&#8217; in which the user can be a part. The Pinball User corresponds pretty much to the &#8216;Reacting&#8217; system; the Thoughtful User is a &#8216;Learning&#8217; system; the Shortcut User is perhaps a special case of a &#8216;Regulating&#8217; system (self-regulating negative feedback to damp variation, to minimise effort, boundedly rational).</h7></p>
<p><h7>I haven&#8217;t yet explored applying Leonard Talmy&#8217;s <a href="http://en.wikipedia.org/wiki/Force_Dynamics">Force Dynamics</a>, as <a href="http://architectures.danlockton.co.uk/2009/04/06/what-sort-of-behaviour/#comment-371926">suggested</a> by <a href="http://infontology.typepad.com/">Simon Winter</a> to these aspects of modelling the user / interaction. I will do, in due course.</h7>    </p>
<p>[1] Perhaps analogous to <a href="http://www.socialtext.net/codev2/index.cgi?what_things_regulate">Lawrence Lessig&#8217;s &#8216;pathetic dot&#8217;</a><br />

			<content:encoded><![CDATA[<p>Here&#8217;s my (rather verbose) response to the three most design-related questions in <a href="http://www.decc.gov.uk/en/content/cms/consultations/smart_metering/smart_metering.aspx">DECC&#8217;s smart meter consultation</a> that I mentioned <a href="http://architectures.danlockton.co.uk/2009/06/18/smart-meter-design-consultation-chance-to-get-involved/">earlier today</a>. Please do get involved in the discussion that Jamie Young&#8217;s started on the <a href="http://groups.google.com/group/design-and-behaviour/browse_thread/thread/e959e9b5350c9b68">Design &#038; Behaviour group</a> and on <a href="http://designandbehaviour.rsablogs.org.uk/2009/05/12/calling-interaction-designers/">his blog at the RSA</a>. </p>
<p><strong>Q12 Do you agree with the Government&#8217;s position that a standalone display should be provided with a smart meter?</strong></p>
<p><img class="floatright" src="http://danlockton.co.uk/research/images/meter.jpg"" alt="Meter in the cupboard" /></p>
<p>Free-standing displays (presumably wirelessly connected to the meter itself, as proposed in <a href="#ref7">[7, p.16]</a>) could be an effective way of bringing the meter &#8216;<strong>out of the cupboard</strong>&#8216;, making an information flow visible which was previously hidden. As Donella Meadows put it when comparing electricity meter placements <a href="#ref1">[1, pp. 14-15]</a> this provides a new feedback loop, &#8220;delivering information to a place where it wasn’t going before&#8221; and thus allowing consumers to modify their behaviour in response.</p>
<p>“An accessible display device connected to the meter” <a href="#ref2">[2, p.8]</a> or “series of modules connected to a meter” <a href="#ref3">[3, p. 28]</a> would be preferable to something where an extra step has to be taken for a consumer to access the data, such as only having a TV or internet interface for the information, but as noted <a href="#ref3">[3, p.31]</a> &#8220;flexibility for information to be provided through other formats (for example through the internet, TV) in addition to the provision of a display&#8221; via an open API, publicly documented, would be the ideal situation. Interesting &#8216;energy dashboard&#8217; TV interfaces have been trialled in projects such as <a href="http://livework.co.uk/">live|work</a>&#8217;s <a href="http://www.livework.co.uk/our-work/low-carb-lane">Low Carb Lane</a> <a href="#ref6">[6]</a>, and offer the potential for interactivity and extra information display supported by the digital television platform, but it would be a mistake to rely on this solely (even if simply because it will necessarily interfere with the primary reason that people have a television).</p>
<p>The question suggests that a single display unit would be provided with each meter, presumably with the householder free to position it wherever he or she likes (perhaps a unit with interchangeable provision for a support stand, a magnet to allow positioning on a refrigerator, a sucker for use on a window and hook to allow hanging up on the wall would be ideal - the location of the display could be important, as noted <a href="#ref4">[4, p. 49]</a>) but the ability to connect multiple display units would certainly afford more possibilities for consumer engagement with the information displayed as well as reducing the likelihood of a display unit being mislaid. For example, in shared accommodation where there are multiple residents all of whom are expected to contribute to a communal electricity bill, each person being aware of others&#8217; energy use (as in, for example, the <a href="http://www.jordanfischer.com/energy_awareness.htm">Watt Watchers</a> project <a href="#ref5">[5]</a>) could have an important social proof effect among peers.</p>
<p>Open APIs and data standards would permit ranges of aftermarket energy displays to be produced, ranging from simple readouts (or even pager-style alerters) to devices and kits which could allow consumers to perform more complex analysis of their data (along the lines of the user-led innovative uses of the <a href="http://www.currentcost.com/">Current Cost</a>, for example <a href="#ref8">[8]</a>) - another route to having multiple displays per household.</p>
<p><strong>Q13 Do you have any comments on what sort of data should be provided to consumers as a minimum to help them best act to save energy (e.g. information on energy use, money, CO2 etc)? </strong></p>
<p><em>Low targets?</em><br />
This really is the central question of the whole project, since the fundamental assumption throughout is that provision of this information will “empower consumers” and thereby “change our energy habits” <a href="#ref3">[3, p.13]</a>. It is assumed that feedback, including real-time feedback, on electricity usage will lead to behaviour change: “Smart metering will provide consumers with tools with which to manage their energy consumption, enabling them to take greater personal responsibility for the environmental impacts of their own behaviour” <a href="#ref4">[4, p.46]</a>; “Access to the consumption data in real time provided by smart meters will provide consumers with the information they need to take informed action to save energy and carbon” <a href="#ref3">[3, p.31]</a>.</p>
<p>Nevertheless, with “the predicted energy saving to consumers&#8230; as low as 2.8%” <a href="#ref4">[4, p.18]</a>, the actual effects of the information on consumer behaviour are clearly not considered likely to be especially significant (this figure is more conservative than the 5-15% range identified by Sarah Darby <a href="#ref9">[9]</a>). It would, of course, be interesting to know whether certain types of data or feedback, if provided in the context of a well-designed interface could improve on this rather low figure: given the scale of the proposed roll-out of these meters (every household in the country) and the cost commitment involved, it would seem incredibly short-sighted not to take this opportunity to design and test better feedback displays which can, perhaps, improve significantly on the 2.8% figure.</p>
<p>(Part of the problem with a suggested figure as low as 2.8% is that it makes it much more difficult to defend the claim that the meters will offer consumers “important benefits” <a href="#ref3">[3, p.27]</a>. The benefits to electricity suppliers are clearer, but ‘selling’ the idea of smart meters to the public is, I would suggest, going to be difficult when the supposed benefits are so meagre.)</p>
<p>If we consider the use context of the smart meter from a consumer’s point of view, it should allow us to identify better which aspects are most important. What is a consumer going to do with the information received? How does the feedback loop actually occur in practice? How would this differ with different kinds of information?</p>
<p><em>Levels of display</em><br />
Even aside from the actual &#8216;units&#8217; debate (money / energy / CO2), there are many possible types and combinations of information that the display could show consumers, but for the purposes of this discussion, I’ll divide them into three levels:</p>
<p><strong>(1) Simple feedback on current (&#038; cumulative) energy use / cost (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#selfmonitoring">self-monitoring</a>)<br />
(2) Social / normative feedback on others’ energy use and costs (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-cognitive/#socialproof">social proof</a> + <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#selfmonitoring">self-monitoring</a>)<br />
(3) Feedforward, giving information about the future impacts of behavioural decisions (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#simulation">simulation &#038; feedforward</a> + <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#kairos">kairos</a> + <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#selfmonitoring">self-monitoring</a>)</strong> </p>
<p>These are by no means mutually exclusive and I’d assume that any system providing (3) would also include (1), for example. </p>
<p>Nevertheless, it is likely that (1) would be the cheapest, lowest-common-denominator system to roll out to millions of homes, without (2) or (3) included – so if thought isn’t given to these other levels, it may be that (1) is all consumers get. </p>
<p>I&#8217;ve done mock-ups of the <em>sort</em> of thing each level might display (of course these are just ideas, and I&#8217;m aware that a) I&#8217;m not especially skilled in interface design, despite being very interested in it; and b) there&#8217;s no real research behind these) in order to have something to visualise / refer to when discussing them.</p>

<em>(1) Simple feedback on current (&#038; cumulative) energy use and cost</em></p>
<p>I’ve tried to express some of the concerns I have over a very simple, cheap implementation of (1) in a scenario, which I’m not claiming to be representative of what will actually happen – but the narrative is intended to address some of the ways this kind of display might be useful (or not) in practice:</p>
<blockquote><p>Jenny has just had a ‘smart meter’ installed by someone working on behalf of her electricity supplier. It comes with a little display unit that looks a bit like a digital alarm clock. There’s a button to change the display mode to ‘cumulative’ or ‘historic’ but at present it’s set on ‘realtime’: that’s the default setting. </p>
<p>Jenny attaches it to her kitchen fridge with the magnet on the back. It’s 4pm and it’s showing a fairly steady value of 0.5 kW, 6 pence per hour. She opens the fridge to check how much milk is left, and when she closes the door again Jenny notices the figure’s gone up to 0.7 kW but drops again soon after the door’s closed, first to 0.6 kW but then back down to 0.5 kW again after a few minutes. Then her two teenage children, Kim and Laurie arrive home from school – they switch on the TV in the living room and the meter reading shoots up to 0.8 kW, then 1.1 kW suddenly. What’s happened? Jenny’s not sure why it’s changed so much. She walks into the living room and Kim tells her that Laurie’s gone upstairs to play on his computer. So it must be the computer, monitor, etc.</p>
<p>Two hours later, while the family’s sitting down eating dinner (with the TV on in the background), Jenny glances across at the display and sees that it’s still reading 1.1 kW, 13 pence per hour. </p>
<p>“Is your PC still switched on, Laurie?” she asks.<br />
“Yeah, Mum,” he replies<br />
“You should switch it off when you’re not using it; it’s costing us money.”<br />
“But it needs to be on, it’s downloading stuff.”</p>
<p>Jenny’s not quite sure how to respond. She can’t argue with Laurie: he knows a lot more than her about computers. The phone rings and Kim puts the TV on standby to reduce the noise while talking. Jenny notices the display reading has gone down slightly to 1.0 kW, 12 pence per hour. She walks over and switches the TV off fully, and sees the reading go down to 0.8 kW.</p>
<p>Later, as it gets dark and lights are switched on all over the house, along with the TV being switched on again, and Kim using a hairdryer after washing her hair, with her stereo on in the background and Laurie back at his computer, Jenny notices (as she loads the tumble dryer) that the display has shot up to 6.5 kW, 78 pence per hour. When the tumble dryer’s switched on, that goes up even further to 8.5 kW, £1.02 per hour. The sight of the £ sign shocks her slightly – can they really be using that much electricity? It seems like the kids are costing her even more than she thought! </p>
<p>But what can she really do about it? She switches off the TV and sees the display go down to 8.2 kW, 98 pence per hour, but the difference seems so slight that she switches it on again – it seems worth 4 pence per hour. She decides to have a cup of tea and boils the kettle that she filled earlier in the day. The display shoots up to 10.5 kW, £1.26 pence per hour. Jenny glances at the display with a pained expression, and settles down to watch TV with her tea. She needs a rest: paying attention to the display has stressed her out quite a lot, and she doesn’t seem to have been able to do anything obvious to save money. </p>
<p>Six months later, although Jenny’s replaced some light bulbs with compact fluorescents that were being given away at the supermarket, and Laurie’s new laptop has replaced the desktop PC, a new plasma TV has more than cancelled out the reductions. The display is still there on the fridge door, but when the batteries powering the display run out, and it goes blank, no-one notices.</p></blockquote>
<p>The main point I&#8217;m trying to get across there is that with a very simple display, the possible feedback loop is very weak. It relies on the consumer experimenting with switching items on and off and seeing the effect it has on the readings, which - while it will initially have a certain degree of investigatory, exploratory interest - may well quickly pall when everyday life gets in the way. Now, without the kind of evidence that’s likely to come out of research programmes such as the <a href="http://business.kingston.ac.uk/charm">CHARM project</a> <a href="#ref10">[10]</a>, it’s not possible to say whether levels (2) or (3) would fare any better, but giving a display the <em>ability</em> to provide more detailed levels of information - particularly if it can be updated remotely - massively increases the potential for effective use of the display to help consumers decide what to do, or even to think about what they&#8217;re doing in the first place, over the longer term.</p>
<p><img src="http://danlockton.co.uk/research/images/smartmeteroptions_no2_600px.jpg" alt="Social / normative feedback on others’ energy use and costs" /></p>
<p><em><strong>(2) Social / normative feedback on others’ energy use and costs</strong></em></p>
<p>A level (2) display would (in a much less cluttered form than what I&#8217;ve drawn above!) combine information about &#8216;what we&#8217;re doing&#8217; (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#selfmonitoring">self-monitoring</a>) with a reference, a <em>norm</em> - what other people are doing (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-cognitive/#socialproof">social proof</a>), either people in the same neighbourhood (to facilitate community discussion), or a more representative comparison such as &#8216;other families like us&#8217;, e.g. people with the same number of children of roughly the same age, living in similar size houses. There are studies going back to the 1970s (e.g. <a href="#ref11">[11</a>, <a href="#ref12">12]</a>) showing dramatic (2 × or 3 ×) differences in the amount of energy used by similar families living in identical homes, suggesting that the behavioural component of energy use can be significant. A display allowing this kind of comparison could help make consumers aware of their own standing in this context. </p>
<p>However, as Wesley Schultz et al <a href="#ref13">[13]</a> showed in California, this kind of feedback can lead to a &#8216;boomerang effect&#8217;, where people who are told they&#8217;re doing better than average then start to care <em>less</em> about their energy use, leading to it increasing back up to the norm. It&#8217;s important, then, that any display using this kind of feedback treats a norm as a goal to achieve <em>only on the way down</em>. Schultz et al went on to show that by using a smiley face to demonstrate social approval of what people had done - <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-cognitive/#affective">affective engagement</a> - the boomerang effect can be mitigated.</p>
<p><img src="http://danlockton.co.uk/research/images/smartmeteroptions_no3_600px.jpg" alt="Feedforward, giving information about the future impacts of behavioural decisions" /></p>
<p><em><strong>(3) Feedforward, giving information about the future impacts of behavioural decisions</strong></em></p>
<p>A level (3) display would give consumers <em>feedforward</em> [14] - effectively, <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#simulation">simulation</a> of <a href="http://architectures.danlockton.co.uk/2009/05/13/what-is-demand-really/">what the impact of their behaviour would be</a> (switching on this device now rather than at a time when there&#8217;s a lower tariff - Economy 7 or a successor), and tips about how to use things more efficiently at the right moment (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#kairos">kairos</a>), and in the right kind of environment, for them to be useful. Whereas &#8216;Tips of the Day&#8217; in software <a href="http://discuss.joelonsoftware.com/default.asp?biz.5.372471.10">frequently annoy users</a> <a href="#ref15">[15]</a> because they get in the way of a user&#8217;s immediate task, with something relatively passive such as a smart meter display, this could be a more useful application for them. The networked capability of the smart meter means that the display could be updated frequently with new sets of tips, perhaps based on seasonal or weather conditions (&#8221;It&#8217;s going to be especially cold tonight - make sure you close all the curtains before you go to bed, and save 20p on heating&#8221;) or even special tariff changes for particular periods of high demand (&#8221;<em>Everyone&#8217;s</em> going to be putting the kettle on during the next ad break in [major event on TV]. If you&#8217;re making tea, do it now instead of in 10 minutes; time, and get a 50p discount on your next bill&#8221;).</p>
<p><em>Disaggregated data: identifying devices</em><br />
This level (3) display doesn&#8217;t require any ability to know what devices a consumer has, or to be able to disaggregate electricity use by device. It can make general suggestions that, if not relevant, a consumer can ignore.</p>
<p>But what about actually disaggregating the data for particular devices? Surely this must be an aim for a really &#8217;smart&#8217; meter display. Since <a href="#ref4">[4, p.52]</a> notes - in the context of discussing privacy - that “information from smart meters could&#8230; make it possible&#8230;to determine&#8230;to a degree, the types of technology that were being used in a property,” this information should clearly be offered to consumers themselves, if the electricity suppliers are going to do the analysis (I&#8217;ve done a bit of a possible mockup, using a more analogue dashboard style). </p>
<p><img src="http://danlockton.co.uk/research/images/smartmeteroptions_no4_600px.jpg" alt="Disaggregated data dashboard" /></p>
<p>Whether the data are processed in the meter itself, or upstream at the supplier and then sent back down to individual displays, and whether the devices are identified from some kind of signature in their energy use patterns, or individual tags or extra plugs of some kind, are interesting technology questions, but from a consumer&#8217;s point of view (so long as privacy is respected), the mechanism perhaps doesn&#8217;t matter so much. Having the ability to see what device is using what amount of electricity, from a single display, would be very useful indeed. It removes the guesswork element.</p>
<p>Now, <a href="http://www.sentec.co.uk/page/our_products/7/">Sentec&#8217;s Coracle technology</a> <a href="#ref16">[16]</a> is presumably ready for mainstream use, with <a href="http://www.sentec.co.uk/content.php?news_id=6">an agreement signed with Onzo</a> <a href="#ref17">[17]</a>, and <a href="http://www.ise-oxford.com/">ISE&#8217;s signal-processing algorithms can identify devices down to the level of makes and models</a> <a href="#ref18">[18]</a>, so it&#8217;s quite likely that this kind of technology will be available for smart meters for consumers fairly soon. But the question is whether it will be something that <em>all</em> customers get - i.e. as a recommendation of the outcome of the DECC consultation - or an expensive &#8216;upgrade&#8217;. The fact that the consultation doesn&#8217;t mention disaggregation very much worries me slightly.</p>
<p>If disaggregated data by device were to be available for the mass-distributed displays, clearly this would significantly affect the interface design used: combining this with, say a level (2) type social proof display could - even if via a website rather than on the display itself - let a consumer compare how efficient particular models of electrical goods are in use, by using the information from other customers of the supplier.</p>
<p>In summary, for Q13 - and I&#8217;m aware I haven&#8217;t addressed the &#8220;energy use, money, CO2 etc&#8221; aspect directly - there are people much better qualified to do that - I feel that the more ability any display has to provide information of different kinds to consumers, the more opportunities there will be to do interesting and useful things with that information (and the data format and API must be open enough to allow this). In the absence of more definitive information about what kind of feedback has the most behaviour-influencing effect on what kind of consumer, in what context, and so on, it&#8217;s important that the display be as adaptable as possible.</p>
<p><strong>Q14 Do you have comments regarding the accessibility of meters/display units for particular consumers (e.g. vulnerable consumers such as the disabled, partially sighted/blind)?</strong></p>
<p>The inclusive design aspects of the meters and displays could be addressed through an exclusion audit, applying something such as the <a href="http://www-edc.eng.cam.ac.uk/betterdesign/downloads/exclusioncalc.html">University of Cambridge&#8217;s Exclusion Calculator</a> <a href="#ref19">[19]</a> to any proposed designs. Many solutions which would benefit particular consumers with special needs would also potentially be useful for the population as a whole - e.g. a buzzer or alarm signalling that a device has been left on overnight which isn&#8217;t normally, or (with disaggregation capability) notifying the consumer that, say, the fridge has been left open, would be pretty useful for everyone, not just the visually impaired or people with poor memory. </p>
<p>It seems clear that having open data formats and interfaces for any device will allow a wider range of things to be done with the data, many of which could be very useful for vulnerable users. Still, fundamental physical design questions about the device - how long the batteries last for, how easy they are to replace for someone with poor eyesight or arthritis, how heavy the unit is, whether it will break if dropped from hand height - will all have an impact on its overall accessibility (and usefulness).</p>
<p>Thinking of &#8216;particular consumers&#8217; more generally, as the question asks, suggests a few other issues which need to be addressed:</p>
<p>- A website-only version of the display data (as suggested at points in the consultation document) would exclude a lot of consumers who are without internet access, without computer understanding, with only dial-up (metered) internet, or simply not motivated or interested enough to check - i.e., it would be significantly exclusionary.</p>
<p>- Time-of-Use (ToU) pricing will rely heavily on consumers actually understanding it, and what the implications are, and changing their behaviour in accordance. Simply charging consumers more automatically, without them having good enough feedback to understand what&#8217;s going on, only benefits electricity suppliers. If demand- or ToU-related pricing is introduced – “the potential for customer confusion&#8230; as a result of the greater range of energy tariffs and energy related information” [4, p. 49] is going to be significant. The design of the interface, and how the pricing structure works, is going to be extremely important here, and even so may still exclude a great many consumers who do not or cannot understand the structure.</p>
<p>- The ability to disable supply remotely <a href="#ref4">[4, p. 12, p.20]</a> will no doubt provoke significant reaction from consumers, quite apart from the terrible impact it will have on the most vulnerable consumers (the elderly, the very poor, and people for whom a reliable electricity supply is essential for medical reasons), regardless of whether they are at fault (i.e. non-payment) or not. There WILL inevitably be errors: there is no reason to suppose that they will not occur. Imagine the newspaper headlines when an elderly person dies from hypothermia. Disconnection may only occur in “certain well-defined circumstances” <a href="#ref3">[3, p. 28]</a> but these will need to be made very explicit. </p>
<p>- “Smart metering potentially offers scope for remote intervention&#8230; [which] could involve direct supplier or distribution company interface with equipment, such as refrigerators, within a property, overriding the control of the householder” <a href="#ref4">[4, p. 52]</a> - this simply offers further fuel for consumer distrust of the meter programme (rightly so, to be honest). As Darby <a href="#ref9">[9]</a> notes, &#8220;the prospect of ceding control over consumption does not appeal to all customers&#8221;. Again, this remote intervention, however well-regulated it might be supposed to be if actually implemented, will not be free from error. “Creating consumer confidence and awareness will be a key element of successfully delivering smart meters” <a href="#ref4">[4, p.50]</a> does not sit well with the realities of installing this kind of channel for remote disconnection or manipulation in consumers&#8217; homes, and attempting to bury these issues by presenting the whole thing as entirely beneficial for consumers will be seen through by intelligent people very quickly indeed.</p>
<p>- Many consumers will simply not trust such new meters with any extra remote disconnection ability – it completely removes the human, the compassion, the potential to reason with a real person. Especially if the predicted energy saving to consumers is as low as 2.8% <a href="#ref4">[4, p.18]</a>, many consumers will (perhaps rightly) conclude that the smart meter is being installed primarily for the benefit of the electricity company, and simply refuse to allow the contractors into their homes. Whether this will lead to a niche for a supplier which does <em>not</em> mandate installation of a meter - and whether this would be legal - are interesting questions.</p>

			<content:encoded><![CDATA[<p>Over on the <a href="http://www.designandbehaviour.com/">Design &#038; Behaviour</a> list/group, <a href="http://designandbehaviour.rsablogs.org.uk/">Jamie Young of the RSA</a> has started a discussion about <a href="http://groups.google.com/group/design-and-behaviour/browse_thread/thread/e959e9b5350c9b68"><strong>the UK&#8217;s &#8217;smart meter&#8217; plans</strong></a>, on which the Department of Energy and Climate Change (DECC) is <a href="http://www.decc.gov.uk/en/content/cms/consultations/smart_metering/smart_metering.aspx">running a consultation</a>.<br />
<span id="more-1112"></span><br />
<a href="http://designandbehaviour.rsablogs.org.uk/2009/05/12/calling-interaction-designers/">Jamie&#8217;s blog post here</a> is a great introduction to why designers should care about this: essentially, it&#8217;s a chance for to get involved in influencing a government / electricity industry initiative which will result in smart meters in <em>25 million</em> homes. The smart meter display is potentially going to be a ubiquitous product, an everyday user experience, and it&#8217;s one of the first times that the UK government has explicitly got involved in using the design of a product / service to influence user behaviour (even if the &#8216;design&#8217; element is barely mentioned in the 40-page consultation document or the numerous addenda). And given the scope of the UK scheme, it&#8217;s likely that other countries will be watching with interest to see how it goes, and what they can learn.</p>
<p>Now it&#8217;s true that there are some great, design-led companies and products appearing such as <a href="http://onzo.co.uk/">Onzo</a>, <a href="http://blog.diykyoto.com/">Wattson</a> and <a href="http://www.greenenergyoptions.co.uk/">GEO</a>, and projects such as <a href="http://www.amee.com/">AMEE</a> - all of whose teams are, I&#8217;m sure, preparing detailed responses to the consultation. But if, as independent designers - interaction designers, information designers, product designers, service designers - we can have some input to the consultation, we should make use of this opportunity. They don&#8217;t come along too often.</p>
<p>Some of the contributions so far to the <a href="http://groups.google.com/group/design-and-behaviour/browse_thread/thread/e959e9b5350c9b68">Design &#038; Behaviour group discussion</a> from <a href="http://clearleft.com/is/jamesbox/">James Box</a>, <a href="http://ableism.wordpress.com/">Gregor Wolbring</a> and <a href="http://www.bdp.com">Simon Thompson</a> have mentioned the need for a public <a href="http://en.wikipedia.org/wiki/API">API</a> - James references <a href="http://speedbird.wordpress.com/2008/12/04/public-objects/">Adam Greenfield</a> here - which can allow users to do interesting things with their data, as well as supporting the needs of older and/or disabled users who may benefit from the information being displayed in different forms.  </p>
<p>There are three main <a href="http://www.decc.gov.uk/en/content/cms/consultations/smart_metering/smart_metering.aspx">consultation</a> questions which have an explicit &#8216;design&#8217; component (though there are others in the document about which I think a few blog readers - as well as myself - may have some opinions):</p>
<p><strong>Q12 Do you agree with the Government&#8217;s position that a standalone display should be provided with a smart meter?</p>
<p>Q13 Do you have any comments on what sort of data should be provided to consumers as a minimum to help them best act to save energy (e.g. information on energy use, money, CO2 etc)?</p>
<p>Q14 Do you have comments regarding the accessibility of meters/display units for particular consumers (e.g. vulnerable consumers such as the disabled, partially sighted/blind)? </strong></p>
<p>If you&#8217;re interested, please do join <a href="http://www.designandbehaviour.com/">Design &#038; Behaviour</a> and contribute your ideas and responses. If you have experience of using smart meters or energy displays elsewhere in the world, or have a great idea for how a new system could work, do get involved.</p>

			<content:encoded><![CDATA[<p>Robert Fabricant of <a href="http://www.frogdesign.com/">frog design</a> – with whom I had a great discussion a couple of weeks ago in London – has an insightful new article up at frog’s <a href="http://designmind.frogdesign.com/">Design Mind</a>, titled, oddly enough, ‘<a href="http://designmind.frogdesign.com/articles/power/design-with-intent.html">Design with Intent: how designers can influence behaviour</a>’ – which tackles the question of how, and whether, designers can and should see their work as being directed towards behaviour change, and the power that design can have in this kind of application. </p>
<p>It builds on a trend evident in frog’s own work in this field, most notably the <a href="http://www.frogdesign.com/services/project-masiluleke.html#/images/project-m-gallery_1.jpg">Project Masiluleke</a> initiative (which seems to have been incredibly successful in behaviour change terms), as well as a theme Robert’s identified talking to a range of practitioners as well as young designers: “We’re experiencing a sea change in the way designers engage with the world. Instead of aspiring to influence user behaviour from a distance, we increasingly want the products we design to have more immediate impact through direct social engagement.”</p>
<p>The recognition of this nascent trend echoes some of the themes of <a href="http://www.designcouncil.info/mt/RED/transformationdesign/">transformation design</a> – a manifesto developed by <a href="http://www.hilarycottam.com/html/whatIdo.htm">Hilary Cottam</a>’s former RED team at the Design Council – and also fits well into what’s increasingly called <em>social design</em>, or <em>socially conscious design</em> – a broad, diverse movement of designers from many disciplines, from service design to architecture, who are applying their expertise to social problems from healthcare to environment to education to communication. With the mantra that ‘<a href="http://socialdesignsite.com/">we cannot not change the world</a>’, groups such as <a href="http://www.design21sdn.com/">Design21</a> and <a href="http://www.projecthdesign.com/">Project H Design</a>, along with alert chroniclers such as <a href="http://kateandrews.wordpress.com/">Kate Andrews</a>, are inspiring designers to see the potential that there is for &#8216;impact through direct social engagement&#8217;: taking on the mantle of Victor Papanek and Buckminster Fuller, motivated by the realisation that design can be more than <a href="http://www.xs4all.nl/~maxb/ftf1964.htm">&#8216;the high pitched scream of consumer selling</a>&#8216;, more than simply reactive. Nevertheless, Robert&#8217;s focus on influencing people&#8217;s behaviour (much as I&#8217;ve tried to make clear with <a href="http://architectures.danlockton.co.uk/what-is-design-with-intent/">my own work on Design with Intent over the last few years</a>), is an explicit emerging theme in itself, and catching the interest of forward-looking organisations such as <a href="http://designandbehaviour.rsablogs.org.uk/">the RSA</a>.</p>
<p><img class="floatleft" src="http://danlockton.co.uk/research/images/people.jpg" alt="People" /></p>
<p><strong>User centred design, constraint and reality</strong></p>
<p>One of the issues Robert discusses is a question I’ve put to the audience in a number of presentations recently – fundamentally, is it still ‘User-Centred Design’ when the designer’s aim is to change users’ behaviour rather than accommodating it? As he puts it, “we influence behaviour and social practice from a distance through the products and services that we create based on our research and understanding of behaviour. We place users at the centre and develop products and services to support them. With UCD, designers are encouraged not to impose their own values on the experience.” Thus, “committing to <em>direct behaviour design</em> [my italics] would mean stepping outside the traditional frame of user-centred design (UCD), which provides the basis of most professional design today.”</p>
<p>Now, ‘direct behaviour design’ as a concept is redolent of <a href="http://en.wikipedia.org/wiki/Architectural_determinism">determinism</a> in architecture, or the more extreme end of <a href="http://www.simplypsychology.pwp.blueyonder.co.uk/behaviourism.html">behaviourism</a>, where people (users / inhabitants / subjects) are seen as, effectively, components in a designed system which will respond to their environment / products / conditioning in a known, predictable way, and can thus be directed to behave in particular ways by changing the design of the system. It privileges the architect, the designer, the planner, the hidden persuader, the controller as a kind of director of behaviour, <a href="http://www.ballardian.com/biblio-high-rise">standing on the top floor</a> observing what he’s wrought down below. </p>
<p>I’ll acknowledge that, in a less extreme form, this is often the intent (if not necessarily the result) behind much design for behaviour change (hence my definition for <a href="http://architectures.danlockton.co.uk/what-is-design-with-intent/">Design with Intent: ‘design that’s intended to influence, or result in, certain user behaviour’</a>). But in practice, people don’t, most of the time, behave as predictably as this. Our behaviour – as Kurt Lewin, James Gibson, Albert Bandura, Don Norman, Herbert Simon, Daniel Kahneman, Amos Tversky and a whole line of psychologists from different fields have made clear – is a (vector) function of our physical environment (and how we perceive and understand it), our social environment (and how we perceive and understand it) and our cognitive decision processes about what to do in response to our perceptions and understanding, working within a bounded rationality that (most of the time) works pretty well. If we perceive that a design is trying to get us to behave in a way we don’t want, we display <a href="http://www.intropsych.com/ch09_motivation/psychological_reactance.html">reactance</a> to it. This is going to happen when you constrain people against pursuing a goal: even the concept of ‘direct behaviour design’ itself is likely to provoke some reactance from you, the reader. Go on: you felt slightly irritated by it, didn’t you?*</p>
<p><img class="floatright" src="http://danlockton.co.uk/research/images/simcard.jpg" alt="SIM Card poka-yoke"/></p>
<p>In some fields, of course, design’s aim really is to <a href="http://architectures.danlockton.co.uk/2009/04/06/what-sort-of-behaviour/">constrain</a> and direct behaviour absolutely – e.g. &#8220;safety critical systems, like air traffic control or medical monitors, where the cost of failure [due to user behaviour] is never acceptable&#8221; (from <a href="http://www.cup.es/uk/catalogue/catalogue.asp?isbn=9780521690317">Cairns &#038; Cox</a>, p.16). But decades of ergonomics, human factors and HCI research suggests that <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-errorproofing/">errorproofing</a> works best when it helps the user achieve the goal he or she already has in mind. It constrains our behaviour, but it also makes it easier to avoid errors we don’t want. We don’t mind not being able to run the microwave oven with the door open (even though we resented seatbelt interlocks). We don’t mind being only being able to put a SIM card in one way round. The design constraint doesn’t conflict with our goal: it helps us achieve it. (It would be interesting to know of cases in Japanese vs. Western manufacturing industry where employees resented the <a href="http://www.mistakeproofing.com/tutorial.html">introduction</a> of <em><a href="http://architectures.danlockton.co.uk/category/poka-yoke/">poka-yoke</a></em> measures – were there any? What were the specific measures that irritated?)</p>
<p>Returning to UCD, then, I would argue that in cases where design with intent, or design for behaviour change, is aligned with what the user wants to achieve, it’s very much still user-centred design, whether enabling, motivating or constraining. It’s the best form of user-centred design, supporting a user’s goals while transforming his or her behaviour. Some of the most insightful current work on influencing user behaviour, from people such as <a href="http://doi.ieeecomputersociety.org/10.1109/ISEE.2008.4562920">Ed Elias at Bath</a> and <a href="http://www-staff.lboro.ac.uk/~cddl/Creating_Sustainable_Behaviour_Tang%20Tang.ppt">Tang Tang at Loughborough</a> [PPT], starts with achieving a deeper understanding of user behaviour with existing products and systems, to identify better how to improve the design; it seems as though companies such as <a href="http://onzo.co.uk/">Onzo</a> are also taking this approach.</p>
<p><strong>Is design ever neutral?</strong></p>
<p>Robert also makes the point that “every [design] decision we make exerts an influence of some kind, whether intended or not”. This argument parallels one of the defences made by <a href="http://www.nudges.org/authors.cfm">Richard Thaler and Cass Sunstein</a> to criticism of their <em><a href="http://papers.ssrn.com/sol3/papers.cfm?abstract_id=405940">libertarian paternalism</a></em> concept: however you design a system, whatever choices you decide to give users, you inevitably frame understanding and influence behaviour. Even not making a design decision at all influences behaviour. </p>
<p><img class="floatleft" src="http://danlockton.co.uk/research/images/staggered_1.jpg" alt="staggered crossing"/></p>
<p>If you put chairs round a table, people will sit down. You might see it as supporting your users’ goals – they want to be able to sit down – but by providing the chairs, you’ve influenced their behaviour. (Compare <a href="http://sethgodin.typepad.com/seths_blog/2007/04/meetings.html">Seth Godin’s ‘no chair meetings’</a>.) If you constrain people to three options, they will pick one of the three. If you give them 500 options, <a href="http://www.ted.com/index.php/talks/view/id/93">they won’t find it easy to choose well</a>. If you give them no options, they can’t make a choice, but might not realise that they&#8217;ve been denied it. And so on. (This is sometimes referred to as ‘<a href="http://www.guardian.co.uk/environment/2007/oct/25/ethicalliving.lifeandhealth1">choice editing</a>’, a phrase which provokes substantial reactance!) If you <a href="http://architectures.danlockton.co.uk/2009/01/05/staggering-insight/">design a pedestrian crossing to guide pedestrians to make eye contact with drivers</a>, you’ve privileged drivers over pedestrians and reinforced the hegemony of the motor car. If you don’t, you’ve shown contempt for pedestrians’ needs. <a href="http://books.google.co.uk/books?id=OB5pPtGQuZgC&#038;lpg=PA91&#038;ots=jmUCXdgd5M&#038;dq=%22Declaration%20by%20Design%3A%20Rhetoric%2C%20Argument%20and%20Demonstration%20in%20Design%20Practice%22&#038;pg=PA91">Richard Buchanan</a> and <a href="http://www.springerlink.com/content/m38028676v3w3214/">Johan Redström</a> have both also dealt with this aspect of ‘<a href="http://www.perina.net/index.php/en/about-mainmenu-69/articles-mainmenu-91/rhetoric-in-design-mainmenu-132">design as rhetoric</a>’, while <a href="http://www.niedderer.org/po.html">Kristina Niedderer&#8217;s &#8216;performative objects&#8217;</a> intended to increase user mindfulness of the interactions occurring.</p>
<p>Thaler and Sunstein’s argument (heavily paraphrased, and transposed from economics to design) is that as every decision we make about designing a system will necessarily influence user behaviour, we might as well try and put some thought into influencing the behaviour that’s going to be best for users (and society)**. And that again, to me, seems to come within the scope of user-centred design. It’s certainly putting the user – and his or her behaviour – at the centre of the design process. But then to a large extent – as Robert’s argued before – <a href="http://designmind.frogdesign.com/blog/behaving-badly-in-vancouver.html">all (interaction) design is about behaviour</a>. And perhaps all design is really interaction design (or ought to be considered as such during at least part of the process).</p>
<p><strong>Persuasion, catalyst and performance design</strong></p>
<p>Robert identifies three broad themes in using design to influence behaviour - <em>persuasion design</em>, <em>catalyst design</em> and <em>performance design</em>. &#8216;Persuasion design&#8217; correlates very closely with the work on <a href="http://books.google.co.uk/books?id=aSfvNuUJNoUC&#038;lpg=PR1&#038;ots=hJUZXKjRSm&#038;dq=persuasive%20technology&#038;pg=PR1">persuasive technology</a> and <a href="http://www.linkedin.com/groups?about=&#038;gid=3345&#038;trk=anet_ug_grppro">persuasive design<a /> which has grown over the past decade, from B.J. Fogg&#8217;s </a><a href="http://captology.stanford.edu/">Persuasive Technology Lab at Stanford</a> to a world-wide collaboration of researchers and practitioners - including <a href="http://www.behaviourchangeandtechnology.org/">designers and psychologists</a> - meeting at the Persuasive conferences (2010&#8217;s will be in <a href="http://www.db.dk/forskning/persuasive2010/">Copenhagen</a>), of which I&#8217;m proud to be a very small part. Robert firmly includes behavioural economics and  <a href="http://architectures.danlockton.co.uk/2008/06/10/nudges-and-the-power-of-choice-architecture/">choice architecture</a> in his description of Persuasion Design, which is something that (so far at least) has not received an explicit treatment in the persuasive technology literature, although individual cognitive biases and heuristics have of course been invoked. I think I&#8217;d respectfully argue that choice architecture as discussed in an economic context doesn&#8217;t really care too much about <em>persuasion</em> itself: it aims to influence behaviours, but doesn&#8217;t explicitly see changing <em>attitudes</em> as part of that, which is very much part of persuasion. </p>
<p>&#8216;Catalyst design&#8217; is a great term - I&#8217;m not sure (other than as the name of <a href="http://www.google.co.uk/search?hl=en&#038;q=%22catalyst+design%22">lots and lots</a> of small consultancies) whether it has any precedent in the design literature or whether Robert coined it himself (something <a href="http://www.fergusbisset.com/blog/">Fergus Bisset</a> asked me the other day on reading the article). On first sight, catalyst design sounds as though it might be identical with Buckminster Fuller&#8217;s <a href="http://en.wikipedia.org/wiki/Trim_tab#Trim_tab_as_a_metaphor">trimtab metaphor</a> - a small component added to a system which initiates or enables a much larger change to happen more easily (what I&#8217;ve tried to think of as &#8216;<a href="http://architectures.danlockton.co.uk/2009/04/06/what-sort-of-behaviour/">enabling behaviour</a>&#8216;). However, Robert broadens the discussion beyond this idea to talk about participatory and open design with users (such as <a href="http://www.janchipchase.com/">Jan Chipchase</a>&#8217;s work - or, if we&#8217;re looking further back, Christopher Alexander and his team&#8217;s groundbreaking <em><a href="http://books.google.co.uk/books?id=u2NSI4vSu_IC&#038;lpg=PP1&#038;ots=J3vvv_PWYM&#038;dq=oregon%20experiment&#038;pg=PP1">Oregon Experiment</a></em>). In this sense, the <em>designer</em> is the catalyst, facilitating innovation and behaviour change. <a href="http://web.mit.edu/evhippel/www/democ.htm">User-led innovation</a> is a massive, and growing, field, with examples of both completely ground-up development (with no &#8216;designer as catalyst&#8217; involved) and programmes where a designer or external expert can, through engaging with people who use and work with a system, really help transform it (Clare Brass&#8217;s SEED Foundation&#8217;s <a href="http://www.seedfoundation.org.uk/projects/hirise/">HiRise project</a> comes to mind here). But it isn&#8217;t often spoken about explicitly in terms of behaviour change, so it&#8217;s interesting to see Robert present it in this context. </p>
<p>Finally, &#8216;performance design&#8217;, as Robert explains it, involves designers performing in some way, becoming immersed in the lives of the people for whom they are designing. From a behaviour change perspective, empathising with users&#8217; mental models, understanding what motivates users during a decision-making process, and why certain choices are made (or not made), must make it easier to identify where and how to intervene to influence behaviour successfully. </p>
<p><strong>Implications for designers working on behaviour change</strong></p>
<p>It&#8217;s fantastic to see high-profile, influential design companies such as frog explicitly recognising the opportunities and possibilities that designers have to influence user behaviour for social benefit. The more this is out in the open as a defined trend, a way of thinking, the more examples we&#8217;ll have of real-life thinking along these lines, embodied in a whole wave of products and services which (potentially) help users, and help society solve <a href="http://architectures.danlockton.co.uk/design-for-sustainable-behaviour/">problems with a significant behavioural component</a>. (And, more to the point, give us a degree of evidence about which techniques actually work, in which contexts, with which users, and <em>why</em> - there are some great examples around at present, both concepts and real products - e.g. as <a href="http://www-staff.lboro.ac.uk/~cddl/how_others_have_done_it.htm">collated here by Debra Lilley</a> - but as yet we just don&#8217;t have a great body of evidence to base design decisions on.) It will also allow us, as users, to become more familiar with the tactics used to influence our behaviour, so we can actively understand the thinking that&#8217;s gone into the systems around us, and choose to reject or opt out of things which <em>aren&#8217;t</em> working in our best interests.</p>
<p>The &#8216;behavioural layer&#8217; (credit to <a href="http://www.slideshare.net/boxman/the-subtle-art-of-persuasion">James Box</a> of <a href="http://clearleft.com/">Clearleft</a> for this term) is something designers need to get to grips with - even knowing where to start when you&#8217;re faced with a design problem involving influencing behaviour is something we don&#8217;t currently have a very good idea about. With my <a href="http://architectures.danlockton.co.uk/2009/04/06/the-design-with-intent-toolkit/">Design with Intent toolkit work</a>, I&#8217;m trying to help this bit of the process a bit, alongside a lot of people interested, on many levels, in <a href="http://groups.google.com/group/design-and-behaviour">how design influences behaviour</a>. It will be interesting over the next few years to see how frog and other consultancies develop expertise and competence in this field, how they choose to recruit the kind of people who are <a href="http://www.slideshare.net/dings">already becoming experts in it</a> - and how they sell that expertise to clients and governments.</p>

			<content:encoded><![CDATA[<p>Hi everyone - the blog&#8217;s undergoing a bit of a redesign (using <a href="http://themasterplan.in/tma">The Morning After</a>) in order to allow some new features and tidy up some of the bodges that had accumulated over the last few years. It was becoming increasingly difficult to maintain the heavily altered version of <a href="http://www.obharath.net/blog/3columnk2/">3ColumnK2</a> I was using, which was giving me a lot of headaches trying to get it to render correctly in IE6 (still around 7% of site visitors). For the next couple of days there may be lots of links that don&#8217;t work, and features missing (there&#8217;s also something wrong with some of the permalinks), so please do bear with me. At present it looks like posting a comment takes you to a blank page; the comment will still appear, but clearly this isn&#8217;t satisfactory so I&#8217;ll try to work out what&#8217;s wrong as soon as I can. Thanks for your patience!</p>

			<content:encoded><![CDATA[<p>Next Wednesday evening, 27th May, I&#8217;ll be giving a presentation about Design with Intent at <a href="http://upcoming.yahoo.com/event/2678312/">SkillSwap Brighton&#8217;s &#8216;Skillswap Goes Behavioural&#8217;</a> alongside Ben Maxwell from <a href="http://www.onzo.co.uk/labs/">Onzo</a> (pioneers of some of the most interesting <a href="http://www.onzo.co.uk/products/">home energy behaviour change design</a> work going on at present). I hope I&#8217;ll be able to give a thought-provoking talk with plenty of ideas and examples that can be practically applied in interaction, service design and user experience. Thanks to <a href="http://twitter.com/boxman">James</a> <a href="http://solita.tumblr.com/">Box</a> of <a href="http://clearleft.com/">Clearleft</a> for organising this.</p>
<p><img src="http://danlockton.co.uk/research/images/walkway_450.jpg" alt="Walkway" /></p>
<p>Then on Thursday 28th, I&#8217;m honoured to be talking as<a href="http://arts.lboro.ac.uk/radar/conversation/"> part of a symposium</a> in Loughborough University&#8217;s <a href="http://www.arts.lboro.ac.uk/radar/">Radar Arts Programme</a>&#8217;s &#8216;<a href="http://www.arts.lboro.ac.uk/radar/whats_on/introduction/">Architectures of Control</a>&#8216; themed events exploring how our lives are impacted by social and environmental controls. </p>
<p>The symposium is interspersed with the performance of <a href="http://arts.lboro.ac.uk/radar/whats_on/mark_titchner/">Mark Titchner&#8217;s &#8216;Debating Society and Run&#8217;</a>, which sounds intriguing. In the symposium I&#8217;ll be talking alongside <a href="http://www.davidcanter.com/index.php?page=biography">Professor David Canter</a>, who seems to have had an incredible career ranging from environmental to offender profiling (inspiration for <em><a href="http://en.wikipedia.org/wiki/Cracker_(TV_Series)">Cracker</a></em>, etc) and <a href="http://www.lboro.ac.uk/departments/ss/staff/hepburn.html">Alexa Hepburn</a>, <a href="http://www-staff.lboro.ac.uk/~ssah2/index.htm">senior lecturer in Social Psychology</a> at Loughborough. Again, I hope my presentation does justice to the event and other participants! Thanks to Nick Slater for inviting me.</p>
<p>The week after (4th June) I&#8217;ll be giving a presentation at <a href="http://www.ufi.com">UFI</a> in Sheffield, best known for its <a href="http://www.learndirect.co.uk/">Learndirect courses</a>. I&#8217;m hoping to be able to run a bit of a very rapid idea-generation workshop as part of this talk, something of an ultra-quick trial of the <a href="www.designwithintent.co.uk">DwI toolkit</a>&#8230;</p>

<p>Who really needs a &#8220;You Are Here&#8221; marker when other visitors&#8217; fingers have done the work for you?</p>
<p>(<em>Above, in Florence; below, in San Francisco</em>)</p>
<p><img src="http://danlockton.co.uk/research/images/sanfrancisco_usemark.jpg" alt="You are here - San Francisco, California" /></p>
<p>Use-marks, like <a href="http://www.uselog.com/2008/08/beauty-of-desire-paths-wear-and-tear.html">desire paths</a>, are a kind of emergent behaviour record of previous users&#8217; perceptions (and perceived affordances), intentions, behaviours and preferences. (As Google&#8217;s search history is a <a href="http://battellemedia.com/archives/000063.php">database of intentions</a>.)</p>
<p>Indeed, while we&#8217;d probably expect the &#8220;You Are Here&#8221; spot to be worn (so it&#8217;s not telling us anything especially new) <strong>can we perhaps think of use-marks / desire paths as being a physical equivalent of <em><a href="http://www.economist.com/research/Economics/alphabetic.cfm?letter=R#revealedpreference">revealed preferences</a></em>?</strong> (Carl Myhill almost makes this point in <a href="http://www.litsl.com/personal/commercial_success_by_looking_for_desire_lines.pdf">this great paper</a> [PDF].)</p>
<p>And (I have to ask), to what extent does the presence of wear and use-marks by previous users influence the use decisions and behaviour of new users (<a href="http://architectures.danlockton.co.uk/2009/04/06/lens-cognitive/#socialproof">social proof</a>)? If you see a well-trodden path, do you follow it? Do you pick a dog-eared library book to read because it is presumably more interesting than the ones that have never been read? What about where you&#8217;re confused by a new interface on, say, a ticket machine? Can you pick it up more quickly by (consciously or otherwise) observing how others have worn or deformed it through prior use?</p>
<p>Can we design public products / systems / services which intentionally wear to give cues to future users? How (other than &#8220;Most read stories today&#8221;) can we apply this digitally?</p>

			<content:encoded><![CDATA[<p><img src="http://danlockton.co.uk/research/images/public_meter.jpg" alt="A publicly visible electricity meter in Claremont, CA" /></p>
<p>In a lot of the debate and discussion about energy, future electricity generation and metering, improved efficiency and influencing consumer behaviour - at least from an engineering perspective - the term &#8220;demand&#8221; is used, in conjunction with &#8220;supply&#8221;, to represent the energy required to be supplied to consumers, much as in conventional &#8220;supply and demand&#8221; economics. </p>
<p>Now, I&#8217;m sure others have investigated this and characterised it economically much better than I can, but it seems to me that demand for energy (and sometimes water) is significantly different to, say, demand for most consumer products in that, for the most part, <em>consumers only &#8220;demand&#8221; it indirectly</em>. It is the products and systems around us which draw the current: they are important <a href="http://carbon.cudenver.edu/~mryder/itc_data/ant_dff.html">actors</a> and have the agency, in a sense (at least unless we really understand the impacts of how they operate). </p>
<p>While with, say, a car&#8217;s fuel consumption, we experience the car&#8217;s demand for fuel, and pay for it, directly in proportion to our demand for travel, with most household electricity use, we not only generally wait a month or more before having to confront the &#8220;demand&#8221; (via the bill), but separating the background demand (such as a refrigerator&#8217;s continuous energy use simply to operate) from conscious demand (such as our decision to use a fan heater all day) is very difficult for us to do as consumers: from a very simple consumer perspective (ignoring things like <a href="http://en.wikipedia.org/wiki/AC_power#Reactive_power_flow">reactive power flow</a>), electricity is interchangeable, and the feedback we get on our behaviour is only very weakly linked to the specifics of that behaviour.</p>
<p><img src="http://danlockton.co.uk/research/images/pricelabelswitch.jpg" alt="An on-off switch with a proce label" /></p>
<p>Basically, then, <strong>a lot of &#8220;demand&#8221; is not <em>conscious</em> demand at all</strong>. Most consumers don&#8217;t make an in-the-moment decision to use more electricity if it gets cheaper (though it may happen over time, e.g. if someone decides to get electric heating because oil heating has become more expensive) or vice versa. The demand is a function of the products and systems around us, our habits, lifestyle and behaviours but it is very difficult for us to see this, and make decisions which have an impact on this. If there are major changes, such as a massively changed price, then real <em>conscious</em> demand changes may happen (so a kind of stepped curve rather than anything smooth) but this is surely not what happens in everyday life. At least at present.</p>
<p>Maybe, then, part of what design could offer here is to help translate this unconscious, product-led, delayed payment demand into a visible, tangible, immediate demand which makes us consider it like any other everyday buying / consumption choice. Real-time <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#selfmonitoring">self-monitoring feedback</a> from clever metering technology (e.g. Onzo or Wattson) could go a long way here, but what about <em><a href="http://architectures.danlockton.co.uk/2009/04/06/lens-persuasive/#simulation">feedforward</a></em>? Can we go as far as <strong>on-off switches with price labels on them?</strong> (Digital, updated, real-time, of course.) Would it make us more price-sensitive to energy costs? Would that influence our behaviour?</p>

Your attention&#8217;s much appreciated and if anyone does try it out on some problems, please do let me know how you get on, what would improve it, and so on. And more examples for each of the patterns are, of course, always welcome!</p>
<p>Printed copies (A2 poster, 135gsm silk finish) are available - the <a href="http://www.amazon.co.uk/Design-Behaviour-Change-Intent-Toolkit/dp/1902316614/">nominal listing on Amazon is £15</a> including postage, but if you&#8217;d like one for much less than that, let me know! (In fact, if you&#8217;re willing to try it out on a design problem, fill in a survey about how you did it, and let me use it as a brief case study, you can have it free.)</p>
<p><strong>Persuasive 2009</strong></p>
<p>I say I&#8217;m just coming up for air briefly, as for the last couple of weeks, among some other major work (which could possibly bear some very nice fruit), I&#8217;ve been putting together my presentation* for <a href="http://www.persuasive2009.net/">Persuasive 2009, the Fourth International Conference on Persuasive Technology</a> in Claremont, California, next week, and at present am desperately trying to finish a lot of other things before flying out on Saturday. It&#8217;ll be my first time across the Atlantic and my girlfriend and I will be having a bit of a holiday afterwards, so I hope a lack of updates and replies, while little different to my usual pattern, will be excusable. But while the conference is on, if there&#8217;s time and no hoo-hah with the wireless and it seems appropriate, I&#8217;ll try and do a bit of blogging, or more likely, Twittering about it (<a href="http://search.twitter.com/search?q=%23persuasive2009">#persuasive2009</a> ?). There are <a href="http://guest.cvent.com/EVENTS/Info/Agenda.aspx?e=e68bac52-4531-4ee0-89ce-6cba52e4ea78">some very interesting people presenting their work</a>.</p>
<p>Anyway, if you missed the update to <a href="http://architectures.danlockton.co.uk/2009/03/11/persuasive-2009/">my earlier post</a>, a preprint version of my paper (with David Harrison, Tim Holley and Neville A. Stanton), <a href="http://danlockton.co.uk/research/Lockton_et_al_Influencing_Interaction_preprint_ACM_disclaimer.pdf">Influencing Interaction: Development of the Design with Intent Method</a> [PDF, 1.6MB] is available. At some point soon this version of the paper will downloadable from Brunel’s research archive, while the ‘proper’ version will be available in the ACM Digital Library. ACM requires me to state the following alongside the link to the preprint:</p>
<blockquote><p>© ACM, 2009. This is the authors’ version of the work. It is posted here by permission of ACM for your personal use. Not for redistribution. The definitive version will be published in Proceedings of Persuasive 2009: Fourth International Conference on Persuasive Technology, Claremont, CA, 26-29 April 2009, ACM Digital Library. ISBN 978-1-60558-376-1.</p></blockquote>
<p>The presentation will include many parts of the paper, but the nature of academic papers like this (submitted in December) is that they are out of date before anyone reads them. So, much of the presentation will be about the <a href="http://architectures.danlockton.co.uk/2009/04/06/the-design-with-intent-toolkit/">DwI toolkit</a> and the reasoning behind bits of it, rather than just sticking to the state of the research six months ago - I hope that&#8217;s reasonable. Last year, presenting on the last day of the conference meant that I was able to spend many hours in a hotel room in Oulu editing and re-editing the presentation (mostly listening to the <a href="http://www.youtube.com/watch?v=SfDzOGCizmI">Incredible Bongo Band&#8217;s version of In-a-Gadda-da-Vida</a> on repeat) to match what I thought the audience would like, and incorporate things I&#8217;d learned during the conference, but this time I&#8217;m on the first day so there isn&#8217;t that opportunity&#8230;</p>
<p><strong>Interfaces article</strong></p>
<p>Also this month, I have a brief article about my research in <em><a href="http://www.bcs-hci.org.uk/about/interfaces">Interfaces</a></em>, the magazine of <a href="http://www.bcs-hci.org.uk/">Interaction, the British Computer Society&#8217;s HCI Group</a>, in its &#8216;My PhD&#8217; series (p. 20-21). <a href="http://www.bcs-hci.org.uk/about/interfaces">Interfaces no. 78 is available to download here</a> (make sure to click on the link below the cover image, as - at time of writing - the cover&#8217;s linked to the previous issue). It&#8217;s a great magazine - redesigned for this issue - with some really <a href="http://www.ixda.org/discuss.php?post=41450">interesting features</a> about aspects of HCI by some well-known names in the field. Thanks to <a href="http://www.uclic.ucl.ac.uk/people/e.calvillo/">Eduardo Calvillo</a> and <a href="http://www.uclic.ucl.ac.uk/people/s.hassard/">Stephen Hassard</a> for making the article possible.</p>
<p>The table in the article was unfortunately truncated during editing so (if I get it in in time) there&#8217;ll be a brief addendum in the next issue with the full table, but I might as well <a href="http://danlockton.co.uk/research/Interfaces_article_fulltable.pdf">make it available here too</a> [PDF, 8kb] - it&#8217;s a brief, not especially exciting summary of some concepts for <strong>influencing householders to close curtains at night to save energy</strong>. (At some point I&#8217;ll do a full case study on this as there are some interesting ideas as well as some very impractical ones.)</p>
<h5><em>*Taking Parkinson&#8217;s Law as an instruction manual seems to be a perpetual habit of mine, so the maximum time allocated to get the presentation done has been more than entirely taken up by getting the presentation done&#8230; it&#8217;s still not quite there, and I&#8217;m not sure whether the format of the auditorium&#8217;s going to allow an interactive element which I would very much like to include but probably won&#8217;t be able to. Also - while <a href="http://prezi.com/">Prezi</a> looks like it might be everything I&#8217;ve ever wanted in presentation software - the workflow of &#8220;doing a PowerPoint&#8221; for me has evolved into a long chain of &#8220;Photoshop - Illustrator - export - Photoshop - Save for Web - insert into PowerPoint&#8221; which I&#8217;m sure I could do more quickly, but lots of conferences and seminars want PPTs rather than PDFs, and the only Mac I have (which once - kind of - belonged to the Duke of Edinburgh [interesting story]) is too slow and old to run anything better.</em></h5>

			<content:encoded><![CDATA[The Security Lens represents a ‘security’ worldview, i.e. that undesired user behaviour is something to deter and/or prevent though ‘countermeasures’ designed into products, systems and environments, both physically and online, with examples such as digital rights management.<br />
<br />
From a designer’s point of view, this can be an ‘unfriendly’ - and in some circumstances unethical - view to take, effectively treating users as ‘guilty until proven innocent’. However, thinking more closely about the patterns, it&#8217;s possible to think of ways that they could be applied to help users control their own habits or behaviour for their own benefit - encouraging exercise, reducing energy use, and so on.<br />
<br />
<a name="patterns"> </a><a name="surveillance"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Surveillance</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“What do I do when other people might be watching?”</strong></h4><br />
<br />
■ If people think others can see what they’re doing, they often change their behaviour in response, through guilt, fear of censure, embarrassment or another mechanism<br />
<br />
■ Techniques range from <a href="http://www.theregister.co.uk/2005/11/15/vehicle_movement_database/">monitoring users’ actions with reporting to authorities</a>, to simpler <a href="http://crimeprevention.rutgers.edu/case_studies/cpted/natsur.htm">‘natural surveillance’</a>, where the layout of an area allows everyone to see what each other is doing. Statistics making public details about users’ contributions to a fund might fit in here too. Surveillance can benefit the user where monitoring allows a desired intervention, e.g. a fall alarm for the elderly<br />
<br />
<img src="http://danlockton.co.uk/research/images/camera_1.jpg" alt="CCTV warning sign" /><img src="http://danlockton.co.uk/research/images/securitylighting_1.jpg" alt="Security lighting" /><br />
<br />
<strong>Examples:</strong> <em>The ubiquitous CCTV—or the threat of it—and security lighting, are both intended to influence user behaviour, in terms of being a deterrent to crime in the first place</em><br />
<br />
<img src="http://danlockton.co.uk/research/images/constraining.png" alt="Constraining behaviour" />This pattern is about <strong>constraining</strong> user behaviour.</div><br />
<br />
<a name="atmospherics"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Atmospherics</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“I can’t hang around here with that racket going on”</strong></h4><br />
<br />
■ Use (or removal) of ambient sensory effects (sound, light, smell, taste, etc) to influence user behaviour<br />
<br />
■ Atmospherics can be ‘discriminatory’, i.e. targeted at particular classes of users, based on some characteristic enabling them to be singled out - such as the <a href="http://architectures.danlockton.co.uk/2009/03/26/anti-teenager-pink-lights-to-show-up-acne/">pink lights supposed to make teenagers with acne too embarrassed to hang around</a> - or ‘blanket’, i.e. targeted at all users, e.g. <a href="http://architectures.danlockton.co.uk/2008/05/23/best-bitter/">Bitrex</a>, a bitter substance, used to discourage drinking weedkiller or biting your nails. <br />
<br />
<img src="http://danlockton.co.uk/research/images/mosquito_small.jpg" alt="The Mosquito anti-teenager sound weapon" /> <img src="http://danlockton.co.uk/research/images/bluelighting_small.jpg" alt="Blue lighting" /><br />
<br />
<strong>Examples:</strong> <em>Two examples of ‘discriminatory’ atmospherics: the <a href="http://architectures.danlockton.co.uk/category/mosquito/">Mosquito</a> emits a 17.4 kHz tone to drive away young people from public places; <a href="http://architectures.danlockton.co.uk/2006/10/28/a-vein-attempt/">blue lighting is used in some public toilets</a> to discourage drug injection by making veins difficult to see</em><br />
<img src="http://danlockton.co.uk/research/images/constraining.png" alt="Constraining behaviour" />This pattern is mainly about <strong>constraining</strong> user behaviour&#8230;<br />
<img src="http://danlockton.co.uk/research/images/motivating.png" alt="Motivating behaviour" />but can also <strong>motivate</strong> a user, e.g. pleasant sensations such as the fresh bread smell used in supermarkets can encourage purchases.</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><br />
<a name="threat"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Threat of damage</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“That&#8217;s going to hurt”</strong></h4><br />
<br />
■ It&#8217;s not nice, but the threat of damage (or injury) lies behind many measures designed to influence behaviour, from tyre damage spikes to barbed wire, electric fences, shards of glass cemented into the top of walls, and so on. <br />
<br />
■ In some cases the <em>threat alone</em> is hoped to be enough to dissuade particular behaviours; in others, it&#8217;s expected that some mild injury or discomfort will occur but put people off doing it again. Warnings are often used (and may be legally required), but this is not always the case.<br />
<br />
<img src="http://danlockton.co.uk/research/images/pig_ears.jpg" alt="Pig ear skate stopper" /><br />
<br />
<strong>Example:</strong> <em>Various kinds of &#8217;skate stopper&#8217; in public places, such as this so-called <a href="http://architectures.danlockton.co.uk/2006/07/09/another-pig-ear-skateboarding-control/">pig ear</a> are designed to cause damage to skateboards (and injury to skateboarders) to <a href="http://architectures.danlockton.co.uk/2006/04/12/making-a-sleek-piece-from-a-pigs-ear/">dissuade them from skating an area</a>.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><br />
<a name="whatyouhave"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>What you have</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Insert passcard now”</strong></h4><br />
<br />
■ ‘What you have’ relies on a user possessing a certain tool or device to enable functionality or gain access. <br />
<br />
■ Aside from the obvious (keys, passcards, <a href="http://architectures.danlockton.co.uk/2006/04/12/dongle-scrapyard/">dongles</a> and so on), there are, for example, specialised screwdrivers for <a href="http://architectures.danlockton.co.uk/2008/05/26/one-way-turn-of-the-screw/">security screws</a>, which rely (largely unsuccessfully) on the distribution channels being kept private. Money itself could be seen as an example of this, especially where it&#8217;s intentionally restricted to influence behaviour (e.g. giving children a certain amount of pocket money to limit what they can buy.)<br />
<br />
<img src="http://danlockton.co.uk/research/images/tickets.jpg" alt="Train tickets" /><br />
<br />
<strong>Example:</strong> <em>When they&#8217;re actually checked, rail or other travel tickets restrict journeys to people who have the right ticket</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="whatyouknow"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>What you know or can do</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Enter password”</strong></h4><br />
<br />
■ ‘What you know or can do’ relies on the <em>capabilities</em> of users - some information or ability which only a subset of users can provide. The most obvious examples are passwords and exams (e.g. driving tests) - testing users’ knowledge / understanding before ‘allowing’ them to perform some behaviour. Often one capability stands as a proxy for another, e.g. <a href="http://www.captcha.net/">CAPTCHAs separating humans from automated bots</a>.<br />
<br />
■ These are often <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-errorproofing/#interlock">interlocks</a> - e.g. breathalyser interlocks on car ignitions, or, one stage further, the ‘puzzle’ interlocks tested during the 1970s, where a driver had to complete an electronic puzzle before the car would start, thus (potentially) catching tiredness or drug use as well as intoxication.<br />
<br />
<img src="http://danlockton.co.uk/research/images/childprooflid.jpg" alt="Childproof lid" /><br />
<br />
<strong>Example:</strong> <em>Childproof lids on bottles of potentially dangerous substances - such as this weedkiller - help prevent access by children, but can also make it difficult for adults with limited dexterity.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="whoyouare"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Who you are</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“If the glove fits&#8230;”</strong></h4><br />
<br />
■ Design based on ‘who you are’ intends to allow or prevent behaviour based on some criteria innate to each individual or group - usually <a href="http://en.wikipedia.org/wiki/Biometrics">biometric</a> - which can&#8217;t be acquired by others.<br />
<br />
■ The aim is usually strong denial of access to anyone not authenticated, but there are also cases of primarily self-imposed ‘who you are’ security, such as the <a href="http://news.bbc.co.uk/1/hi/technology/7214240.stm">Mukurtu system</a>, stamping ‘Confidential’ on documents, and so on.<br />
<br />
<img src="http://danlockton.co.uk/research/images/fingerprintscanner_joshbanc.jpg" alt="Fingerprint scanner - photo by Josh Bancroft on Flickr" /><br />
<br />
<strong>Example:</strong> <em>Fingerprint scanners are becoming increasingly common on computer hardware.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="whatyouvedone"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>What you&#8217;ve done</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Do 10 minutes more exercise to watch this show”</strong></h4><br />
<br />
■ Systems which alter the options available to users based on their current / past behaviour are increasingly easy to imagine as the technology for logging and tracking actions becomes easier to include in products (see also <a href="#surveillance">Surveillance</a>). Products which ration people&#8217;s use, or require some &#8216;work&#8217; to achieve a goal, fit in here.<br />
<br />
■ These could simply ‘lock out’ someone who has abused/misused a system (as happens with various anti-spam systems), or, more subtly, could divide users into classes based on their previous behaviour and provide different levels of functionality in the future.<br />
<br />
<img src="http://www.danlockton.co.uk/research/images/square-eyes-1.jpg" alt="Square Eyes by Gillian Swan" /><br />
<br />
<strong>Example:</strong> <em><a href="http://www.newscientist.com/article/dn7395-smart-shoes-decide-on-television-time.html">Gillian Swan&#8217;s </a></em>Square Eyes<em> restricts children&#8217;s TV viewing time based on the amount of exercise they do (measured by these special insoles)</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="whereyouare"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #9A8478"><h3 style="color: #FFFFFF; background-color: #9A8478; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Where you are</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“This function is disabled for your current location”</strong></h4><br />
<br />
■  ‘Where you are’ security selectively restricts or allows a user functions based on a user’s location<br />
<br />
■  Examples include buildings intended to have no mobile phone reception (perhaps ‘for security reasons’, or maybe for the benefit of other users, e.g. in a cinema), and IP address geographic filtering, where website users identified as being in different countries are given access to different content.<br />
<br />
<img src="http://danlockton.co.uk/research/images/trolleys.jpg" alt="Trolley wheels lock when taken outside car park" /><br />
<br />
<strong>Example:</strong> <em>Some supermarket trolleys have devices fitted to lock the wheels, <a href="http://www.gray-matter.co.uk/radlok.php">mechanically</a> or electronically when taken outside a defined area. Less high-tech versions <a href="http://www.digitalspy.co.uk/forums/showpost.php?p=17897311&#038;postcount=10">have also been used</a>!</em></div><br />

The Visual Lens combines ideas from <a href="http://en.wikipedia.org/wiki/The_semantic_turn">product semantics</a>, <a href="http://www.aber.ac.uk/media/Documents/S4B/semiotic.html">semiotics</a>, ecological psychology and <a href="http://homepages.ius.edu/rallman/gestalt.html">Gestalt psychology</a> about how users perceive patterns and meanings as they interact with the systems around them. <br />
<br />These techniques are often applied by interaction designers without necessarily considering how they can influence user behaviour.<br />
<br />

<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Prominence &amp; visibility</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“You can’t miss it”</strong></h4><br />
■ Design certain elements so they’re more prominent, obvious, memorable or visible than others, to direct users’ attention towards them, making it easier for users to pick up the message intended, or pick the ‘best’ options from a set of choices<br />
<br />
■ Simple prominence is one of the most basic design principles for influencing user behaviour, but visibility can also include using transparency strategically as part of a system—drawing users’ attention to elements which would otherwise be hidden<br />
<br />
<img src="http://danlockton.co.uk/research/images/prominence1.jpg" alt="Rising bollard sign" /><img src="http://danlockton.co.uk/research/images/prominence2.jpg" alt="Warning sign" /><br />
<br />
<strong>Examples:</strong> <em>The most important warning signs should be the most prominent—if a user only has time to take in one message, it should be the one that matters the most (above)</em><br />
<br />
<em>A Dyson vacuum’s transparent chamber makes forgetting to empty it unlikely, thus keeping the effectiveness of the cleaner high and improving user satisfaction (below)</em><br />
<br />

<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />This pattern is about <strong>enabling</strong> user behaviour: making it easier to make certain choices</div><br />
<a name="metaphors"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Metaphors</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“This reminds me of one of those, so I expect<br />
it works that way too”</strong></h4><br />
■ Use design elements from a context the user understands in a new system, to imply how it should be used; make it easy for users to understand a new system in terms they already understand<br />
<br />
■ There’s a danger of oversimplification, or misleading users about the consequences of actions, if <a href="http://www.slideshare.net/dansaffer/the-role-of-metaphor-in-interaction-design">metaphor use</a> is taken to extremes; it can also trap users in old behaviour patterns<br />
<br />
<img src="http://danlockton.co.uk/research/images/macdesktop.jpg" alt="Mac desktop" /><br />
<br />
<strong>Examples:</strong> <em>Everyday software interfaces (above and below left) combine hundreds of metaphors, from the ‘desktop’, ‘folders’ and ‘trash/recycle bin’ themselves to the icons used for graphics functions such as zoom (magnifying glass), eyedropper and so on. <a href="http://jalopnik.com/5070371/ford-smartgauge-lcd-instrument-panel-brings-futuristic-look-green-leaves-to-2010-hybrids">Ford’s SmartGauge</a> (below right) uses ‘leaves’ to represent efficiency of a user’s driving style</em><br />

<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />Metaphors are mainly about <strong>enabling</strong> user behaviour&#8230;<br />
<img src="http://danlockton.co.uk/research/images/motivating.png" alt="motivating behaviour" />but can also <strong>motivate</strong> a user to &#8216;know&#8217; by increasing mindful understanding of how best to use a system.</div><br />
<div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><br />
<a name="perceived"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Perceived affordances</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Looks like you use it <em>this</em> way&#8230;”</strong></h4><br />
■ <a href="http://www.jnd.org/dn.mss/affordance_conv.html">Perceived affordances</a> are <em>what it looks like we can do with something</em>. A button looks like we should push it; a door with a handle looks like we should pull it, whereas a door with a plate looks like we should push it. This is <a href="http://www.interaction-design.org/encyclopedia/affordances.html">fundamental to interaction design</a>, and in influencing user behaviour, since the actions a design &#8217;suggests&#8217; to a user will probably be carried out. (<a href="http://architectures.danlockton.co.uk/2008/05/29/un-hiding-affordance/">There may be hidden affordances too</a>.)<br />
<br />
■ Related ideas include <em><a href="http://www.cooper.com/journal/2002/05/dont_get_burned_by_bad_mapping.html">mappings</a></em> - laying out controls so they relate intuitively to the functions they control - and <em>perceived constraints</em>, what users perceive they <em>can&#8217;t</em> do with something.<br />
<br />
<img src="http://danlockton.co.uk/research/images/perceivedaffordances_door.jpg" alt="Door handle suggests it should be pulled" /><br />
<br />
<strong>Example:</strong> <em>Where a door has a handle, we assume we should pull it. When this isn&#8217;t the case, usability suffers!</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><br />
<a name="impliedsequences"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Implied sequences</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Easy as 1,2,3&#8230;”</strong></h4><br />
■ Presenting items in an implied sequence suggests to users that they should be used / experienced in order. Remember that in while in western countries, our reading direction leads us to assume sequences go left-to-right, in other cultures right-to-left may be the norm, e.g. <a href="http://www.mozilla.org.il/releases/screenshot-v1.5.shtml">this Hebrew version of the Mozilla browser</a> with right-facing &#8220;back&#8221; arrow and left-facing &#8220;forward&#8221; arrow.<br />
<br />
■ The sequence of choices can also suggest levels of priority / hierarchy - there&#8217;s a small advantage for <a href="http://www.uvm.edu/~vlrs/PoliticalProcess/ballotordereffects.pdf">candidates who are listed first on a ballot paper</a> [PDF]. The order in which options are revealed can also be important, both in terms of <a href="http://en.wikipedia.org/wiki/Recency_effect">what people remember</a> and <a href="http://dx.doi.org/10.1016/S0749-5978(03)00080-3">how they make comparisons</a><br />
<br />
<img src="http://danlockton.co.uk/research/images/toggleswitches_trancedmoogle.jpg" alt="Toggle switches by trancedmoogle" /><br />
<br />
<strong>Example:</strong> <em>Rows of switches such as these can suggest a sequential form of operation</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="possibilitytrees"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Possibility trees</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“What route should I take?”</strong></h4><br />
■ Possibility trees show users what routes they can follow to achieve a goal, or what results different behaviours can lead to. The way these are presented, via instructions, an interface, or even signage or maps - wayfinding (e.g. <a href="http://www.tfl.gov.uk/businessandpartners/publications/5708.aspx">these Transport for London studies</a>) - can influence the choices users make. .<br />
<br />
■ <a href="http://architectures.danlockton.co.uk/2007/08/03/pier-pressure/">They can be used strategically</a>: showing users <a href="http://www.sabre-roads.org.uk/forum/viewtopic.php?p=225667">the routes that planners would <em>prefer</em> them to take</a>, or the actions that designers would like users to take.<br />
<br />
<img src="http://danlockton.co.uk/research/images/tubemap.png" alt="The London Underground map" /><br />
<br />
<strong>Example:</strong> <em>Once people have become used to using a highly stylised map to plan journeys, such as the <a href="http://www.tfl.gov.uk/gettingaround/1106.aspx">London Underground map</a> here, it can affect perceptions of places&#8217; location in real life. For example, Willesden Junction and North Acton stations are a 10-15 minute walk apart, but the distortion introduced by the map suggests that the distance is much further, which in turn can influence the transport choices people make.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="watermarking"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Watermarking</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Taking (or showing) ownership”</strong></h4><br />
■ In this context, watermarking means making the ownership (or background) of something evident to users. If people feel they own a device, through some kind of personalisation or acknowledgement that it&#8217;s theirs, they will often use it differently to when it seems like it belongs to someone else.<br />
<br />
■ One application of this to influencing behaviour is to make it clear or obvious that some shared resources belong to <em>everyone</em>, or to the <em>community</em>, rather than <em>no-one in particular</em>.<br />
<br />
<img src="http://danlockton.co.uk/research/images/watermarking_litter_BBC.jpg" alt="Writing on packaging to 'watermark' it with the purchaser's name" /><br />
<br />
<strong>Example:</strong> <em>A Gloucestershire shopkeeper has taken to <a href="http://news.bbc.co.uk/1/hi/england/gloucestershire/7952397.stm">writing customers&#8217; names on the packaging of snacks they buy</a>, to encourage them not to litter by &#8216;taking ownership&#8217; - it has apparently been especially successful with children.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="proximity"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Proximity &amp; similarity</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Those look like they go together”</strong></h4><br />
■ Users will tend to perceive that design elements (buttons, controls etc) which look similar, or are arranged together, will have similar functions or work together as a group (<a href="http://www.usask.ca/education/coursework/skaalid/theory/gestalt/similar.htm">Gestalt proximity and similarity</a>).<br />
<br />
■ This can be used strategically to influence user behaviour as a kind of <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-cognitive/#framing">framing</a> technique: group functions that you want users to perceive as going together, or give the controls similar shapes or colours. Likewise, introducing deliberate <em><a href="http://books.google.co.uk/books?id=xwINxyVBeuIC&amp;pg=PA122&amp;lpg=PA122&amp;dq=krippendorff+discontinuity">discontinuity</a></em> or separation between elements can lead users to treat them very differently.<br />
<br />
<img src="http://www.danlockton.co.uk/research/images/switches.jpg" alt="Group of 6 switches" /><br />
<br />
<strong>Example:</strong> <em>Bringing light switches together like this allows them all to be switched off at once more easily when leaving a room, but can work against the intuitive mapping linking each switch to the lights it controls.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="colour"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #EC008C"><h3 style="color: #FFFFFF; background-color: #EC008C; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Colour &amp; contrast</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“I simply chose the one that stood out the most”</strong></h4><br />
■  Use colour and visual contrast to influence users&#8217; perceptions and moods, suggest associations between particular behaviours and outcomes, and cause users to notice important elements or information (remembering that colour-blindness affects many millions of users, and so has <a href="http://en.wikipedia.org/wiki/Color_blindness#Design_implications_of_color_blindness">implications for designers</a>)<br />
<br />
■  While some research shows that certain colours can have direct effects on behaviour in certain situations (e.g. the <a href="http://www.colormatters.com/body_pills.html">colour of pills</a>), the evidence in general is weaker <a href="http://www.colourlovers.com/blog/2009/03/25/how-color-influences-consumer-behavior">than is sometimes implied</a>. Nevertheless, clever use of colour can help, support and guide user decision-making and so influence behaviour.<br />
<br />
<img src="http://danlockton.co.uk/research/images/bakermillerpink.png" alt="Baker-Miller pink" /><br />
<br />
<strong>Example:</strong> <em><a href="http://bacweb.the-bac.edu/~michael.b.williams/baker-miller.html">Baker-Miller Pink</a> or &#8220;<a href="http://www.colormatters.com/body_pink.html">drunk-tank pink</a>&#8221; was developed through trials in prisons where painting a cell this colour was found, in certain circumstances, to reduce inmates&#8217; aggression.</em></div><br />

			<content:encoded><![CDATA[<p>The Errorproofing Lens represents a worldview treating deviations from the target behaviour as ‘errors’ which design can help avoid, either by making it easier for users to work without making errors, or by making errors impossible in the first place.</p>
<p>This view on influencing behaviour is often found in health &amp; safety-related design, medical device design and manufacturing engineering. <em><a href="http://architectures.danlockton.co.uk/2009/02/27/eight-design-patterns-for-errorproofing/">More commentary&#8230;</a></em></p>

<h3 style="color: #FFFFFF; background-color: #FF0000; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Defaults</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“What happens if I leave the settings how they are?”</strong></h4>
<p>■ Choose ‘good’ <a href="http://architectures.danlockton.co.uk/category/defaults/">default settings</a> and options, since many users will stick with them, and only change them if they feel they really need to (see <a href="http://www.softwaredefaults.com/">Rajiv Shah&#8217;s work</a>, <a href="http://nudges.wordpress.com/tag/default-rules/">Thaler &amp; Sunstein</a> and <a href="http://harvardbusinessonline.hbsp.harvard.edu/b01/en/common/viewFileNavBean.jhtml?_requestid=27200">Goldstein at al</a> [PDF article preview] for more detailed examinations of defaults and their impacts)</p>
<p>■ How easy or hard it is to change settings, find other options, and undo mistakes also contributes to user behaviour here</p>
<p><img src="http://danlockton.co.uk/research/images/defaults_printquality.png" alt="Default print quality settings" /> <img src="http://danlockton.co.uk/research/images/defaults_donorcard.jpg" alt="Donor card" /></p>
<p><strong>Examples:</strong> <em>With most printer installations, the default print quality is usually not ‘Draft’, even though this would save users time, ink and money.<br />
In the UK, organ donation is ‘opt-in’: the default is that your organs will not be donated. In some countries, an ‘opt-out’ system is used, which <a href="http://www.guardian.co.uk/society/2007/jul/18/health.medicineandhealth">can lead to higher rates of donation</a> </em></p>
<p><img src="http://danlockton.co.uk/research/images/constraining.png" alt="Constraining behaviour" />This pattern is mainly about <strong>constraining</strong> user behaviour&#8230;<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />but can also <strong>enable</strong> a user to make the &#8216;right&#8217; choice.</div>

<h3 style="color: #FFFFFF; background-color: #FF0000; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Interlock</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“That doesn’t work unless you do this first”</strong></h4>
<p>■ Design the system so users have to perform actions in a certain order, by preventing the next operation until the first is complete: a <em><a href="http://www.interaction-design.org/encyclopedia/forcing_functions.html">forcing function</a></em></p>
<p>■ Can be irritating or helpful depending on how much it interferes with normal user activity—e.g. <a href="http://architectures.danlockton.co.uk/simple-control-in-products/#interlock">seatbelt-ignition interlocks</a> have historically been very unpopular with drivers</p>
<p><img src="http://danlockton.co.uk/research/images/interlock_microwave.jpg" alt="Interlock on microwave oven door" /> <img src="http://danlockton.co.uk/research/images/interlock_ATM.jpg" alt="Interlock on ATM - card returned before cash dispensed" /></p>
<p><strong>Examples:</strong> <em>Microwave ovens don’t work until the door is closed (for safety).<br />
Most cash machines don’t dispense cash until you remove your card (so it’s less likely you forget it)</em><br />
<img src="http://danlockton.co.uk/research/images/constraining.png" alt="Constraining behaviour" />This pattern is mainly about <strong>constraining</strong> user behaviour.</div>

<h4 style="text-align: center; margin-top: 0cm"><strong>“This operation cannot be stopped right now”</strong></h4>
<p>■ Keep an operation going (lock-in) or prevent one being started (lock-out) - a <em>forcing function</em></p>
<p>■ Can be helpful (e.g. for safety or improving productivity, such as preventing accidentally cancelling something) or irritating for users (e.g. diverting the user’s attention away from a task, such as unskippable DVD adverts before the movie)</p>

<h4 style="text-align: center; margin-top: 0cm"><strong>“Are you sure?”</strong></h4>
<p>■ Introduce an extra step, either as a confirmation (e.g. an &#8220;Are you sure?&#8221; dialogue) or a ‘speed-hump’ to slow a process down or prevent accidental errors - another <em>forcing function</em>. Most <a href="http://architectures.danlockton.co.uk/2008/02/12/home-made-instant-poka-yokes/">everyday poka-yokes (&#8221;useful landmines&#8221;)</a> are examples of this pattern</p>

<h4 style="text-align: center; margin-top: 0cm"><strong>“Did you mean&#8230;?”</strong></h4>
<p>■ Design systems which partially correct errors made by the user, or suggest a different action, but allow the user to undo or ignore the self-correction – e.g. <a href="http://blogoscoped.com/archive/2009-01-29-n34.html">Google’s “Did you mean…?”</a> feature</p>
<p>■ An alternative to full, automatic self-correction (which does not actually influence the <em>user’s</em> behaviour)</p>

<h4 style="text-align: center; margin-top: 0cm"><strong>“That&#8217;s the size it comes in”</strong></h4>
<p>■ Use the size of ‘portion’ to influence <a href="http://mindlesseating.org/">how much users consume</a>: <em><a href="http://bps-research-digest.blogspot.com/2006/06/power-of-one-why-larger-portions-cause.html">unit bias</a></em> means that people will often perceive what they’re provided with as the ‘correct’ amount</p>
<p>■ Can also be used explicitly to control the amount users consume, by only releasing one portion at a time, e.g. with <a href="http://architectures.danlockton.co.uk/2008/07/07/motel-6cc/">soap dispensers</a></p>

<h4 style="text-align: center; margin-top: 0cm"><strong>“It&#8217;s warning me I haven&#8217;t put my seatbelt on”</strong></h4>
<p>■  Detect and provide warning feedback (audible, visual, tactile) if a condition occurs which the user would benefit from fixing (e.g. upgrading a web browser), or if the user has performed actions in a non-ideal order</p>
<p>■ Doesn’t force the user to take action before proceeding, so not as ‘strong’ an errorproofing method as an <a href="#interlock">interlock</a>.</p>

			<content:encoded><![CDATA[<br /><br />
The Persuasive Lens represents the emerging field of <a href="http://captology.stanford.edu/">persuasive technology</a>, where computers, mobile phones and other systems with interfaces are used to persuade users: changing attitudes and so changing behaviour through contextual information, advice and guidance. The patterns here are based mainly on ideas from BJ Fogg&#8217;s <em><a href="http://books.google.co.uk/books?id=aSfvNuUJNoUC">Persuasive Technology: Using Computers to Change What We Think and Do</a></em> and related work.<br />
<br />
The major applications so far have been in influencing behaviour for social benefit, e.g. persuading people to give up bad habits, adopt healthier lifestyles or reduce their energy use.<br />
<br />
<a name="patterns"> </a><a name="selfmonitoring"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Self-monitoring</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“How is my behaviour affecting the system?”</strong></h4><br />
■ Give the user feedback on the impact of the way a product is being used, or how well he or she is doing relative to a target or goal<br />
<br />
■ Self-monitoring can involve real-time feedback on the consequences of different behaviours, so that the ‘correct’ next step can immediately be taken, but in other contexts, ‘summary’ monitoring may also be useful, such as giving the user a report of behaviour and its efficacy over a certain period. Over time, this can effectively ‘train’ the user into a better understanding of the system<br />
<br />
<img src="http://danlockton.co.uk/research/images/energymeters_450.jpg" alt="Energy meters" /><br />
<br />
<strong>Examples:</strong> <em>Energy meters (above) of many kinds allow householders to see which appliances use the most electricity, and how much this is costing, whether or not they choose to act.<br />
<br />
<a href="http://www.printgreener.com/">GreenPrint</a>, a ‘better print preview’, provides users (and, in an office context, their bosses!) with a summary of the resources it’s helped save, environmentally and financially (below)</em><br />
<br />
<img src="http://danlockton.co.uk/research/images/greenprint_450.png" alt="Greenprint report" /><br />
<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />This pattern is about <strong>enabling</strong> user behaviour: making it easier to make certain choices</div><br />
<a name="kairos"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong><em>Kairos</em></strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“What’s the best action for me to take right now?”</strong></h4><br />
■ Suggest a behaviour to a user at the ‘opportune’ moment, i.e. when it would be most efficient or the most desirable next step to take<br />
<br />
■ Often a system can ‘cue’ the suggested behaviour by reminding the user; suggestions can also help steer users away from incorrect behaviour next time they use the system, even if it’s too late this time<br />
<br />
<img src="http://danlockton.co.uk/research/images/speed_display_450.jpg" alt="Automatic speed display" /><br />
<br />
<strong>Examples:</strong> <em>Automatic warning signs (above) can alert drivers to upcoming dangers at the right point for them to respond and slow down accordingly<br />
<br />
Volvo once offered a gearchange suggestion light (below), helping drivers drive more efficiently and save fuel</em><br />
<br />

<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />Kairos can be about <strong>enabling</strong> user behaviour at exactly the right moment&#8230;<br />
<img src="http://danlockton.co.uk/research/images/motivating.png" alt="motivating behaviour" />but can also <strong>motivate</strong> a user by increasing mindfulness right before action is taken.</div><br />
<div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><br />
<a name="reduction"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Reduction</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Just one click away&#8230;”</strong></h4><br />
■ Simplification of tasks – <a href="http://lawsofsimplicity.com/2006/07/23/law-1-reduce-3/"><em>thoughtful reduction</em> in John Maeda&#8217;s terminology</a> – makes it easier for users to follow the intended behaviour.<br />
<br />
■ Using ‘shortcuts’ to remove cognitive load from the user (e.g. <a href="http://www.energylabels.org.uk/eulabel.html">energy labels</a>) can be very powerful, but be aware of the manipulation potential (see also <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-cognitive/#framing">framing</a>). By removing stages where the user has to think about what he or she&#8217;s doing, you may also risk creating exactly the kind of mindless interaction that lies behind many of the problems you may be trying to solve!<br />
<br />
<img src="http://danlockton.co.uk/research/images/ecobutton_sm.jpg" alt="Eco Button" /><br />
<br />
<strong>Example:</strong> <em>The <a href="http://www.eco-button.com/uk/A3.0.about.htm">Eco Button</a> reduces the steps needed to put a computer into a low-power state, thus making it much easier for users to save energy.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><br />
<a name="tailoring"> </a><div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Tailoring</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“It&#8217;s like it knows me”</strong></h4><br />
■ Tailor / personalise the information displayed or the way a system responds to individual users’ needs / abilities / situations, to engage users to interact in the intended way<br />
<br />
■ Adaptive systems can learn about their users’ habits, preferences, etc and respond accordingly; simpler systems which can ‘detect’ some salient criteria and offer behavioural suggestions could also be effective<br />
<br />
<img src="http://danlockton.co.uk/research/images/pam_200.jpg" alt="PAM Personal Activity Monitor" /><br />
<br />
<strong>Example:</strong> <em>The <a href="http://www.pam.com/uk/product/"><em>Pam</em> personal activity monitor</a>, by measuring acceleration rather than simply numbers of steps, allows the feedback it gives and exercise régimes it suggests to be tailored to the user, which allows it to be much more like a &#8216;personal trainer&#8217; than a conventional pedometer.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="tunnelling"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Tunnelling</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Guide me, O thou great persuader”</strong></h4><br />
■ Guided persuasion: a user ‘agrees’ to be routed through a sequence of pre-specified actions or events; commitment to following the process motivates the user to accept the outcome<br />
<br />
■ B.J. Fogg uses the example of <a href="http://books.google.co.uk/books?id=aSfvNuUJNoUC&#038;pg=PA34&#038;vq=tunneling&#038;source=gbs_search_r&#038;cad=1_1">people voluntarily hiring personal trainers</a> to guide them through fitness programmes (which also involves <a href="#tailoring">tailoring</a>). Many software wizards which go beyond merely simplifying a process, into the area of shaping users&#8217; choices, would also fit in here; there is the potential to lead users into taking actions they wouldn&#8217;t do in circumstances outside the tunnel, which must be carefully considered ethically.<br />
<br />
<img src="http://danlockton.co.uk/research/images/foxit_tunnelling.png" alt="Tunnelling in the Foxit Reader installer" /><br />
<br />
<strong>Example:</strong> <em>The installation wizard for the <a href="http://www.foxitsoftware.com/pdf/reader/">Foxit PDF Reader</a> tries to get the user to &#8216;choose&#8217; extra bundled installation options such as making <a href="http://www.ask.com/">ask.com</a> the default search engine, by presenting them as <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-errorproofing/#defaults">default</a> parts of the process. By this stage the user cannot exit the tunnel.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="feedbackthroughform"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Feedback through form</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Look and feel”</strong></h4><br />
■ Use the form of an object itself as a kind of interface, providing the user with feedback on the state of the system, or cues/suggestions of what to do next. It could be visual changes to the form, or <a href="http://en.wikipedia.org/wiki/Haptic_technology">haptic</a> (i.e. sensed through touch)<br />
<br />
■ This technique is often overlooked in rushing towards high-tech display solutions; can be as simple as something which intentionally deforms when used in a particular manner to give the user feedback, or changes shape to draw attention to the state it’s in<br />
<br />
<img src="http://danlockton.co.uk/research/images/puzzleswitch_200.jpg" alt="AWARE puzzle switch" /><br />
<br />
<strong>Example:</strong> <em>The <a href="http://www.tii.se/aware/designConcept.html">AWARE</a> Puzzle Switch - designed by <a href="http://www.loove.org/">Loove Broms</a> and <a href="http://www.tii.se/aware/people.html#karin">Karin Ehrnberger</a> gives more obvious feedback that a light switch is left on, through obvious <a href="http://architectures.danlockton.co.uk/2008/06/13/exploiting-desire-for-order/">&#8216;disorder&#8217;</a>.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="simulation"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Simulation &amp; feedforward</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“What would happen if I did this?”</strong></h4><br />
■ Provide a simulation or ‘feedforward’ showing users what consequences particular behaviours will have, compared with others: make cause and effect clearer to users<br />
<br />
■ Showing users what will happen if they click ‘here’, or how many miles‘ fuel they have left if they continue driving as they are, tooltips, and even the ‘Preview’ and ‘Undo’ functions of common software, where changes can be easily tried out and then reversed/not applied, can all be considered kinds of feedforward or simulation<br />
<br />
<img src="http://www.danlockton.co.uk/research/images/lumpsumsimulation.png" alt="Loan repayment simulator" /><br />
<br />
<strong>Example:</strong> <em><a href="http://www.useit.com/alertbox/20030303.html">Jakob Nielsen suggests</a> that “a financial website could&#8230;encourage users to save more for retirement [by showing] a curve of the user’s growing nest egg and a photo of ‘the hotel you can afford to stay at when travelling to Hawaii after you retire’ for different levels of monthly investment”; interactive savings / loan simulators such as <a href="http://au.pfinance.yahoo.com/calculators/lump-sum-repay-simulator.html">this from Yahoo!</a> are increasingly common, and have the potential to influence user behaviour.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="operant"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Operant conditioning</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Rewards for good behaviour”</strong></h4><br />
■  Operant conditioning means reinforcing or ‘training’ particular user behaviour by rewarding it (or, indeed, punishing it). This could be a system where a user chooses to work towards a target behaviour, being rewarded for every bit of progress towards it, or something which periodically (perhaps unpredictably) rewards continued engagement, thus keeping users interacting (e.g. a fruit machine)<br />
<br />
■  Sometimes the reward is a function of the system itself: saving energy naturally results in lower electricity bills. The system must make the user aware of this, though, otherwise a reinforcing effect is less likely to occur.<br />
<br />
<img src="http://danlockton.co.uk/research/images/kpt.jpg" alt="KPT 5 Shapeshifter" /><br />
<br />
<strong>Example:</strong> <em>E.g. <a href="http://www.metafilter.com/60062/Tonight-Were-Gonna-Design-Like-its-1999">Kai’s Power Tools</a> (pioneering visual effects software) revealed ‘bonus functions’ to reward users who developed their skills with particular tools</em></div><br />
</div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="respondent"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Respondent conditioning</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“Force of habit”</strong></h4><br />
■ Respondent conditioning, also known as classical conditioning, can be applied to influence behaviour through helping users subconsciously associate particular actions with particular stimuli or settings, and responding accordingly: basically, developing habits which become <em>reflexes</em>. If you automatically feel for the light switch when you enter or leave a room, or brake when something appears in front of you on the road, this has effectively become a reflex action.  <br />
<br />
■ Using design, we could try to associate existing routines with new behaviours we would like - e.g. checking the house&#8217;s energy use when we look out of the window to see what the weather&#8217;s like outside, by fixing an energy display to the window (a concept by <a href="http://moreassociates.com/news/">More Assocates</a> / <a href="http://www.onzo.co.uk/">Onzo</a> used this idea). Or we could try to <em>undo</em> these conditioned reflexes where they are damaging in some way to the user, by putting something else in the way. <br />
<br />
<img src="http://danlockton.co.uk/research/images/nicostopper_200.jpg" alt="Nicostopper" /><br />
<br />
<strong>Example:</strong> <em>Smoking is often a conditioned reflex; many devices have been designed to try and undo or thwart this reflex when the user wants to quit, such as the <a href="http://architectures.danlockton.co.uk/2006/12/30/limiting-frequency-of-cigarette-use/">Nicostopper, which stores 10 cigarettes and releases them only at pre-determined intervals</a>.</em></div><br />
</div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="casa"> </a><br />
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #F7931D"><h3 style="color: #FFFFFF; background-color: #F7931D; text-align: center; margin-top: 0cm; padding-bottom: 3%"><br /><strong>Computers as social actors</strong></h3><br />
<h4 style="text-align: center; margin-top: 0cm"><strong>“I like my Mac because it&#8217;s so <em>friendly</em>”</strong></h4><br />
<br />
■ The <em><a href="http://csli-publications.stanford.edu/site/1575860538.html">media equation</a></em> is the idea that &#8220;media equals real life&#8221;, i.e. that many people treat media (computers, TV, other systems) as if they were real people in terms of social interaction. If users believe that a computer (/system) is ‘on their side’, and helping them achieve their goals, it’s probably more likely they’ll follow advice given by the system: you can design systems to use ‘persuasive agents’, whether explicitly using simulated characters (e.g. in games) or by somehow giving the interface a personality.  <br />
<br />
■ If the system frustrates the user, advice is more likely to be ignored; equally, beware of the <a href="http://www.arclight.net/~pdb/nonfiction/uncanny-valley.html">uncanny valley</a>. As pervasive computing and artificial intelligence develop, establishing computers as ‘social actors’ in everyday life offers a lot of potential for more ‘persuasive products’.<br />
<br />
<img src="http://danlockton.co.uk/research/images/clippit.png" alt="Microsoft Office Clippit" /><br />
<br />
<strong>Example:</strong> <em>Microsoft&#8217;s <a href="http://en.wikipedia.org/wiki/Office_Assistant">Office Assistants</a>, including Clippit / Clippy here, were an attempt to give a helpful personality to Office, but <a href="http://xenon.stanford.edu/~lswartz/paperclip/">proved unpopular enough</a> with many users that Microsoft <a href="http://www.appscout.com/2007/02/to_kill_a_paperclip.php">phased them out</a>.</em></div><br />

			<content:encoded><![CDATA[<p>The Cognitive Lens draws on research in behavioural economics and cognitive psychology looking at how people make decisions, and how this is affected by ‘heuristics’ and ‘biases’. If designers understand how users make interaction decisions, that knowledge can be used to influence interaction behaviour.</p>
<p>Equally, where users often make poor decisions, design can help counter this, although this risks the accusation of design becoming a tool of the ‘nanny state’ which ‘knows what’s best’.</p>
<p><a href="http://en.wikipedia.org/wiki/List_of_cognitive_biases">Many dozens of cognitive biases and heuristics</a> have been identified by psychologists and behavioural economists, a lot of which could potentially be applied to the design of products and services. The seven detailed below are some of the most commonly used; this selection draws heavily on the work of <a href="http://www.influenceatwork.com/index2.html">Robert Cialdini</a>.</p>
<p><a name="patterns"> </a><a name="socialproof"> </a></p>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Social proof</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“What do other users like me do in this situation?”</strong></h4>
<p>■ Users will often decide what to do based on what those around them do (the <em><a href="http://www.overcomingbias.com/2007/12/aschs-conformit.html">conformity bias</a></em>), or how popular an option is; make use of this strategically to influence behaviours</p>
<p>■ Social proof works especially well when there is a peer group or users identify with (or aspire to joining) the group against whose behaviour theirs is being compared; an element of competition can be intentionally introduced</p>
<p><img src="http://www.danlockton.co.uk/research/images/socialproof_facebook.png" alt="Facebook application demonstrating social proof" /></p>
<p><strong>Examples:</strong> <em>Facebook’s ‘n of your friends added x application’ (above), Amazon’s various recommendation features, and statistics announcing the popularity of a particular website or product, such as the Feedburner ‘chicklet’ here all imply that ‘people like you are doing this, therefore you might want to as well’</em><img src="http://www.danlockton.co.uk/research/images/socialproof_chicklet.png" alt="Feedburner's chicklet demonstrates social proof" align="top" /> </p>
<p><img src="http://www.danlockton.co.uk/research/images/socialproof_amazon.png" alt="Amazon's recommendation features demonstrate social proof" /> </p>
<p><img src="http://danlockton.co.uk/research/images/motivating.png" alt="Motivating behaviour" />Social proof is mainly about <strong>motivating</strong> user behaviour&#8230;<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />but can also <strong>enable</strong> a user to &#8216;know&#8217; what to do, by making it easier to see how others are doing it.</div>
<p><a name="framing"> </a>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Framing</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“Well, if you put it that way&#8230;”</strong></h4>
<p>■ Present choices to a user in a way that ‘frames’ perceptions and so influences behaviour, e.g. framing energy saving as ‘saving you money’ rather than ‘saving the environment’; categorise functions strategically so that users perceive them as being related</p>
<p>■ An obvious principle to many designers (and politicians, and estate agents); there are many possible framing tactics, such as use of language to give positive / negative associations to options (e.g. ‘sports suspension’ sounds better than ‘hard suspension’). Often used to deceive customers</p>
<p><img src="http://danlockton.co.uk/research/images/starbucks_framing_missshari.jpg" alt="Starbucks' menu demonstrating framing - image by Miss Shari" /></p>
<p><strong>Examples:</strong> <em>Starbucks’ drink sizes—at least on the menu (above)—start with ‘tall’, framing the implied range of sizes much further up the scale, to avoid any negative or mediocre implications that ‘small’ or ‘medium’ might have.</p>
<p>The <a href="http://www.neilturner.me.uk/2008/08/06/knock-off_nigel.html">‘Knock-off Nigel’ anti-DVD-copying campaign</a> (below) frames crimes against another person, such as theft of money, in the same bracket as downloading a movie, to imply that people who engage in one also engage in the other.</em></p>
<p><img src="http://danlockton.co.uk/research/images/knockoff.png" alt="The 'Knock-off Nigel' campaign equates theft of money with downloading a movie" /></p>
<p><img src="http://danlockton.co.uk/research/images/motivating.png" alt="Motivating behaviour" />Framing is about <strong>motivating</strong> people to behave in particular ways.</div>
<div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><br />
<a name="reciprocation"> </a>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Reciprocation</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“Return the favour”</strong></h4>
<p>■ Users often feel obliged to return ‘favours’: design systems which encourage users to trade or share information or resources</p>
<p>■ Can involve ‘guilting’ the user, but best if the user genuinely wants to return a favour</p>
<p><img src="http://danlockton.co.uk/research/images/azureus.png" alt="Azureus message encouraging users to reciprocate for having downloaded a file by continuing to seed it" /></p>
<p><strong>Example:</strong> <em>This message from the BitTorrent client Azureus (now <a href="http://azureus.sourceforge.net/">Vuze</a>) encourages users to &#8216;reciprocate&#8217; for having downloaded a file by continuing to seed it</em></div>
<p></div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><br />
<a name="commitment"> </a></p>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Commitment &#038; consistency</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“Stick to the plan”</strong></h4>
<p>■ Get users to commit in some way to an idea or goal; they’re then more likely to behave in accordance with this to appear or feel &#8216;consistent&#8217;</p>
<p>■ Can be used less ethically (e.g. the <a href="http://architectures.danlockton.co.uk/2008/10/02/swoopo-irrational-escalation-of-commitment/">‘irrational escalation of commitment’ involved in Swoopo</a>)</p>
<p><img src="http://danlockton.co.uk/research/images/watermeter_phatcontroller.jpg" alt="Choosing to have a water meter installed demosntrates some commitment to saving water. Photo by Phatcontroller" /></p>
<p><strong>Example:</strong> <em>Voluntarily choosing to have a water meter installed can demonstrate some commitment to reducing water, which may persist as a household tries to remain consistent with the commitment.</em></div>
<p></div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="affective"> </a></p>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Affective engagement</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“Getting emotionally involved”</strong></h4>
<p>■ Design <a href="http://www.affectivedesign.org/">&#8216;affective&#8217; products</a> and systems to evoke emotional response as a way of <a href="http://www.design-emotion.com/">engaging users</a> and influencing attitudes and behaviours</p>
<p>■ Designers have traditionally been very good at manipulating aesthetics to inspire <a href="http://studiolab.io.tudelft.nl/desmet/dissertation">emotional response</a>, but new technologies allow new opportunities, especially with gaming.</p>
<p><img src="http://danlockton.co.uk/research/images/smiley.png" alt="Smiling and frowning faces on electricity bills engage consumers affectively" /></p>
<p><strong>Example:</strong> <em>Using <a href="http://www.nytimes.com/2009/01/31/science/earth/31compete.html?_r=1&#038;partner=rss&#038;emc=rss">smiling (or frowning) faces on customers&#8217; electricity bills</a> can increase the emotional response associated with the bill, and lead to (slight) reductions in electricity use. By comparing customers&#8217; use to their neighbours, this strategy also made use of <a href="#socialproof">social proof</a></em></div>
<p></div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="authority"> </a>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Authority</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“She know&#8217;s what she&#8217;s doing”</strong></h4>
<p>■ Many users will behave as suggested by an ‘authority figure’ or expert even if that behaviour is outside what they would consider normal; systems can be designed to make use of this effect</p>
<p>■ At least three mechanisms at work here: ‘appeal to authority’ in terms of attitude / behaviour guidance, <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-security/#threat">perceived threat</a> to users who ‘disobey’ authoritative messages, and desire to become more like the ‘pros’ by imitation</p>
<p><img src="http://danlockton.co.uk/research/images/twitter_authority_1.png" alt="Barack Obama on Twitter" /><br />
<img src="http://danlockton.co.uk/research/images/twitter_authority_2.png" alt="Stephen Fry on Twitter" /></p>
<p><strong>Example:</strong> <em>How much of Twitter&#8217;s success at engaging users to join and participate has been due to well-publicised &#8216;authority&#8217; figures embracing it?</em></div>
<p></div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="scarcity"> </a></p>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #006699">
<h3 style="color: #FFFFFF; background-color: #006699; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Scarcity</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“Not much left, better use it wisely”</strong></h4>
<p>■ Whether scarcity is real or not in a situation, if it’s <em>perceived</em> to be, users may value something more, and so alter their behaviour in response: design systems strategically to emphasise the scarcity of a resource</p>
<p>■ Can be down to <a href="http://loss-aversion.behaviouralfinance.net/">loss aversion</a>; artificial scarcity can also be introduced (e.g. <a href="http://www.eff.org/issues/drm">digital rights management</a>)</p>
<p><img src="http://danlockton.co.uk/research/images/scarcity_milesleft.jpg" alt="Miles left on this tankful of fuel" /></p>
<p><strong>Example:</strong> <em>Digital fuel gauges showing the remaining range on the current tank can help concentrate drivers&#8217; minds on the scarcity value of the fuel. See also self-monitoring.</em></div>

			<content:encoded><![CDATA[<p>The Architectural Lens draws on techniques used to influence user behaviour in architecture, urban planning and related disciplines such as traffic management and crime prevention through environmental design (see also the <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-security/">Security lens</a>).</p>
<p>While the techniques have been developed in the built environment, many of the ideas can also be applied in interaction and product design, even in software or services; they are effectively about using the <em>structure of systems</em> to influence behaviour.</p>
<p><a name="patterns"> </a><a name="positioning"> </a></p>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #73B74A">
<h3 style="color: #FFFFFF; background-color: #73B74A; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Positioning &#038; layout</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“I wonder why they laid it out like that”</strong></h4>
<p>■ Arrange elements to affect how people use them—it can involve simply positioning elements (functions, buttons, etc) in <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-visual/#impliedsequences">sequence</a>, hiding elements so they are only available for interaction in that sequence, or designing paths to converge or diverge intentionally</p>
<p>■ The layouts of supermarkets, shopping malls and offices can influence the paths taken by users, exposing them to the shelves, shops and colleagues in a strategic order or hierarchy</p>
<p><img src="http://www.danlockton.co.uk/research/images/bathroom1.jpg" alt="Bathroom mirror layout - photos by Meagan Call" /> <img src="http://www.danlockton.co.uk/research/images/bathroom2.jpg" alt="Bathroom mirror layout - photos by Meagan Call" /></p>
<p><strong>Examples:</strong> <em>In this service station bathroom (above), the mirrors have been moved from behind the sinks <a href="http://architectures.danlockton.co.uk/2007/12/11/i-believe-in-mirror-queues/">to an intentionally awkward position near the door</a>, so users don’t spend too long in front of them. See <a href="http://hadesarrow.blogspot.com/2007/11/bathroom-oddities.html">this discussion by Meagan Call</a>.</p>
<p>Chicane layouts (below) force drivers to yield priority to oncoming traffic, reducing speeds.</em></p>

<p><img src="http://danlockton.co.uk/research/images/constraining.png" alt="Constraining behaviour" />This pattern is mainly about <strong>constraining</strong> user behaviour&#8230;<br />
<img src="http://danlockton.co.uk/research/images/enabling.png" alt="Enabling behaviour" />but can also <strong>enable</strong> a user by making it easier to use/experience things in the &#8216;right&#8217; order.</div>

<h4 style="text-align: center; margin-top: 0cm"><strong>“It&#8217;s much more comfortable if you use it this way rather than that way”</strong></h4>
<p>■ Use materials individually or in combination, chosen for particular properties which influence or affect user behaviour—e.g. comfortable chairs to encourage visitors to sit down, uncomfortable café seating to discourage long stays</p>
<p>■ A change in properties, such as the sudden roughness of rumble strips on the road, can signal to a user that a change in behaviour is appropriate</p>
<p><img src="http://danlockton.co.uk/research/images/oulu-cycle-track.jpg" alt="Rough textured paving dividing pedestrian and cycle paths in Oulu, Finland" /></p>
<p><strong>Examples:</strong> <em>Rough-textured paving (above) can act as a subtle barrier<br />
between the cycle and pedestrian tracks: stray over the line on a bike and you’ll feel it.</p>
<p>This bench on the Paris Métro (below) is intentionally too uncomfortable to act as anything other than a very temporary perch: it prevents sleeping or loitering.</em></p>
<p><img src="http://danlockton.co.uk/research/images/uncomfortable-bench.jpg" alt="Uncomfortable 'bench' on Paris Metro" /></p>
<p><img src="http://danlockton.co.uk/research/images/constraining.png" alt="Constraining behaviour" />This pattern is mainly about <strong>constraining</strong> user behaviour&#8230;<br />
<img src="http://danlockton.co.uk/research/images/motivating.png" alt="Motivating behaviour" />but can also <strong>motivate</strong> a user, e.g. by &#8216;rewarding&#8217; certain behaviour with comfort</div>
<div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><br />
<a name="segmentation"> </a>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #73B74A">
<h3 style="color: #FFFFFF; background-color: #73B74A; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Segmentation &#038; spacing</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“One at a time, please”</strong></h4>
<p>■ Break up a system into multiple elements, spaced strategically to influence how a user can interact with them</p>
<p>■ Often used so users can interact with only one element at a time, or to make sure they share a system with others. Removing spacing, or integrating segmented elements, can also be used intentionally </p>
<p><img src="http://danlockton.co.uk/research/images/segmented_benches.jpg" alt="Segmented seats on the Paris Metro" /></p>
<p><strong>Example:</strong> <em>These individual seats replace a bench on the Paris Métro - meaning that someone cannot lie down or occupy more than one.</em></div>

<h3 style="color: #FFFFFF; background-color: #73B74A; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Orientation</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“Slanty design”</strong></h4>
<p>■ Use angled elements in a system to influence interaction, e.g. by making it easier or more difficult for some actions to occur than others. Also known as <a href="http://architectures.danlockton.co.uk/2007/10/29/slanty-design/">&#8217;slanty design&#8217; (Russell Beale).</a></p>
<p>■ Can also be used to ‘funnel’ users, e.g. <a href="http://architectures.danlockton.co.uk/2009/01/05/staggering-insight/">staggered pedestrian crossings making sure users face oncoming traffic</a> </p>
<p><img src="http://danlockton.co.uk/research/images/slantybin.jpg" alt="New Pig cigarette bin with angled top" /></p>
<p><strong>Example:</strong> <em>Sloping lids <a href="http://architectures.danlockton.co.uk/2007/04/09/tidying-up-the-cig-bin/">on cigarette bins</a> to discourage placing of litter on top</em></div>
<p></div><div style="width:47%; float: left; padding-right: 6%; display: inline;" class="post_column_1"><p><a name="removal"> </a></p>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #73B74A">
<h3 style="color: #FFFFFF; background-color: #73B74A; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Removal</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“You can&#8217;t use it if it isn&#8217;t there”</strong></h4>
<p>■ Simply remove system elements or cues which allow or encourage particular behaviours you don&#8217;t want to happen, or which would allow a user to proceed without thinking</p>
<p>■ Can also increase the <a href="http://architectures.danlockton.co.uk/2009/04/06/lens-visual/#prominence">transparency of a system</a>, making it easier for users to see the consequences of their (and others’) actions </p>
<p><img src="http://danlockton.co.uk/research/images/sevendials_fisheye.jpg" alt="Shared Space at Seven Dials in London. Photo by cheddarcheez" /></p>
<p><strong>Example:</strong> <em>The <a href="http://en.wikipedia.org/wiki/Shared_space">&#8216;naked roads&#8217;/&#8217;shared space&#8217; approach</a> of removing road markings and signage to influence more careful driving in urban areas, e.g. here at <a href="http://www.livablestreets.com/streetswiki/seven-dials">Seven Dials</a> near Covent Garden in London</em></div>
<p></div><div style="width:47%; float: left; padding-right: 0%; display: inline;" class="post_column_1"><p><a name="movement"> </a>
<div style="padding:0px 0px 0px 0px; color: #555555; background-color: #eeeeee; border-style: solid; border-color: #73B74A">
<h3 style="color: #FFFFFF; background-color: #73B74A; text-align: center; margin-top: 0cm; padding-bottom: 3%"><strong>Movement &#038; oscillation</strong></h3>
<h4 style="text-align: center; margin-top: 0cm"><strong>“It&#8217;s brought right in front of you”</strong></h4>
<p>■ Dynamic system elements which move to guide users through a process or present things/functions to users in the order they should experience them - e.g. a conveyor belt in a factory or sushi bar</p>
<p>■ Can also be used to discourage users loitering, or blocking others’ paths, e.g. in a popular museum exhibit   </p>
<p><img src="http://danlockton.co.uk/research/images/walkway.jpg" alt="Moving walkway at Heathrow" /></p>
<p><strong>Example:</strong> <em>A moving walkway (or an escalator), aside from making it easier for pedestrians to get about, also prevents them blocking the path of others</em></div>

			<content:encoded><![CDATA[<p>The diﬀerent patterns (initially just those featured on the poster) have each been given a badge (or two) showing whether they have the eﬀect of <em>enabling</em>, <em>motivating</em>, or <em>constraining</em> user behaviour:</p>
<h4><strong>Enabling behaviour</strong></h4>
<p><img src="http://danlockton.co.uk/research/images/enabling_200.png" alt="Enabling behaviour" /><br />
<strong>Enabling ‘desirable’ behaviour by making it easier for the user than the alternatives</strong></p>
<h4><strong>Motivating behaviour</strong></h4>
<p><img src="http://danlockton.co.uk/research/images/motivating_200.png" alt="Motivating behaviour" /><br />
<strong>Motivating users to change behaviour by education, incentives and changing attitudes</strong></p>
<h4><strong>Constraining behaviour</strong></h4>
<p><img src="http://danlockton.co.uk/research/images/constraining_200.png" alt="Constraining behaviour" /><br />
<strong>Constraining users to ‘desirable’ behaviour by making alternatives diﬃcult or impossible</strong></p>
<p>&nbsp;<br />This way of classifying the patterns can be useful to think about when you’re coming up with concepts and evaluating them. What are you trying to achieve in terms of inﬂuencing behaviour? How would <em>you</em> react, as a user, faced with the design? Would it inﬂuence <em>your</em> behaviour? Why?</p>
<p>Much work in <a href="http://captology.stanford.edu/">Persuasive Technology</a> has taken the approach of <strong>motivating</strong> behaviour, with attitude change usually a precursor, but BJ Fogg’s <em>reduction</em> and <em>tunnelling</em> (Fogg, 2003) are arguably also about <strong>enabling</strong> particular behaviours by making them simpler (see also Maeda, 2006). Buckminster Fuller’s <a href="http://en.wikipedia.org/wiki/Trim_tab#Trim_tab_as_a_metaphor">‘trimtab’</a> concept—<a href="http://architectures.danlockton.co.uk/2008/07/18/buckminster-fuller-and-design-with-intent/">“modify[ing] the environment in such a way as to get man moving in preferred directions”</a> (Krausse &#038; Lichtenstein, 2001)—also accords with the enabling approach and provides a link to the wider field of design for social benefit. Human factors strategies aimed at influencing behaviour in a health and safety context often employ a <strong>constraining</strong> approach. </p>
<p>The approach used in practice—and hence the patterns and concepts chosen for further development—may, of course, be dictated by the client or other stakeholders rather than being the designer’s decision.</p>
<p>P.S. If you can come up with better icons (the &#8216;Constraining&#8217; one does look rather intestinal), or your own classifications, please do let us know in the comments below&#8230;</p>

<h4><strong>Start with the problem</strong></h4>
<p>You have a product, service or environment—a <em>system</em>—where users’ behaviour is important to it working properly (safely, eﬃciently), so ideally you’d like people to use it in a certain way.</p>
<p>Or maybe you have a system where it would be desirable to alter the way that people use it, to improve things for users, the people around them, or society as a whole.</p>
<p>How can you modify the design, or redesign the system, to achieve this: to <em>inﬂuence</em>, or change users’ behaviour?</p>
<h4><strong>The design patterns</strong></h4>
<p>The Design with Intent Toolkit aims to help designers faced with ‘design for behaviour change’ briefs. The <a href="http://bura.brunel.ac.uk/bitstream/2438/3258/1/DwI_Toolkit_v09_linked_eBook_with_indiv_pages.pdf" onClick="javascript: pageTracker._trackPageview('/research/DwI_09revised');">poster</a>* features 12 design patterns which recur across design ﬁelds (interaction, products, architecture), and there are also 35 more detailed here on the website. Some of the names will be unfamiliar, but we hope the patterns and examples will be understandable, and inspire your own concepts.</p>
<p>Think about how you might apply the ideas to your brief, and what could work given what you know about the problem. If you get stuck, try combining ideas from diﬀerent patterns: many real examples can be thought of as using two or more patterns.</p>
<p>The patterns are grouped into six ‘lenses’, each oﬀering a diﬀerent worldview on design and behaviour. The lenses allow you to ask “How might someone else approach the problem?” and ought to help you think outside your initial perspective (or your client’s):</p>

			<content:encoded><![CDATA[<p>The &#8216;<a href="http://architectures.danlockton.co.uk/category/dwi-method/">Design with Intent method</a>&#8216;, on which I&#8217;m working as the first part of my PhD, has been fairly sparsely reported on this blog. This is intended to be an innovation method for helping designers faced with &#8220;behaviour change&#8221; problems come up with useful solutions, or in situations where helping users to use a product or system more efficiently would be worthwhile. The ideas that have gone into it are (mostly) the &#8216;positive&#8217; side of what we&#8217;ve discussed on the blog for the last few years.</p>
<p>The brief series of posts from last summer about <a href="http://architectures.danlockton.co.uk/2008/05/01/getting-someone-to-do-things-in-a-particular-order-part-1/">getting people to do things in a particular order</a>, which more recently got some attention from Kati London&#8217;s &#8216;<a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/1/class-calendar#feb3">Persuasive Technologies: Designing the Human</a>&#8216; class at NYU&#8217;s Interactive Telecommunications Program (<a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/293/exposure-and-intent">with</a> <a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/333/friendadder">some</a> <a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/375/week-2-response">very</a> <a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/315/week-2-2">interesting</a> <a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/356/reading-and-observation">student</a> <a href="http://designingthehuman.com/interface/itp-spring-2009-persuasive-technology/350/subversive-revelation-of-intent">commentary</a>) was based on a relatively early iteration of the method. At some point, I&#8217;ll draw up a comparison between the iterations of the method, even if simply for my own clarity of mind - it&#8217;s helpful to record why I changed different aspects along the way.</p>
<p>The initial plan had been for it to be almost <a href="http://www.mazur.net/triz/">TRIZ-like</a> in terms of &#8216;prescribing&#8217; relevant design techniques to help achieve particular target behaviours. The first few iterations of the method thus took the form of a kind of hierarchical decision tree. <a href="http://www.livework.co.uk/">Live|Work</a>&#8217;s very helpful advice to me last summer to reduce the prescriptive nature slightly by having a kind of illustrated &#8216;idea space&#8217; led - in due course - to the version tested in the <a href="http://architectures.danlockton.co.uk/2008/12/12/invitation-to-participate/">pilot studies</a> carried out in late 2008 and earlier this year. What the studies showed, among other things (to be reported in the <a href="http://architectures.danlockton.co.uk/2009/03/11/persuasive-2009/">Persuasive 2009 paper!</a>) was that many designers, when asked to come up with concept solutions, don&#8217;t really like working from categories and rules and hierarchies, even where they would be useful. Some do (and with impressively exhaustive efficiency), but many don&#8217;t: they preferred to use the method as a kind of well of inspiration, without necessarily using it in any kind of procedural way. </p>
<p>So - and there&#8217;s another reason for this, too, which I&#8217;ll be able to announce at some point - it seemed sensible to redesign the method to accommodate both modes of working: a &#8216;prescription mode&#8217; for the more procedure-driven designer, and an &#8216;inspiration mode&#8217; for the designer who prefers less bounded creativity (a bit more like <a href="http://www.ideo.com/work/item/method-cards/">IDEO&#8217;s method cards</a>, but not quite as unstructured as the <a href="http://www.rtqe.net/ObliqueStrategies/">Oblique Strategies</a>). The inspiration mode is essentially a very simplified, flattened set of design patterns loosely grouped into different &#8216;lenses&#8217; representing views on influencing behaviour, but with no real structure beyond that. It&#8217;s more of a &#8216;toolkit&#8217; than a method, and because of its relative simplicity it seems worth releasing to get some feedback without too much more work. The &#8220;<a href="http://architectures.danlockton.co.uk/2009/02/27/eight-design-patterns-for-errorproofing/">eight design patterns for errorproofing</a>&#8221; post from a few weeks back is a kind of preview of part of it.  </p>
<p>On Monday morning, then, there&#8217;ll be a large poster available to download on the blog, and I&#8217;ll do a series of posts forming the online component of the toolkit. So please, feel free to comment, make suggestions for improvements or better examples, or pick holes in it!</p>
<p>P.S. I&#8217;m aware the blog needs a bit of housekeeping in terms of making the sidebar work properly again in IE, fixing the very out-of-date blogroll, and my appalling sloth in replying to people who&#8217;ve very kindly sent very interesting links and ideas. I will try to get round to it all soon.</p>

<p>In a similar vein to the <a href="http://architectures.danlockton.co.uk/category/mosquito/">Mosquito</a>, <a href="http://architectures.danlockton.co.uk/2008/05/30/steps-read-made-seats/">intentionally shallow steps</a> (and, superficially at least&#8211;though not really&#8211;<a href="http://architectures.danlockton.co.uk/2006/10/28/a-vein-attempt/">blue lighting in toilets</a>, which <a href="http://shakeoutblog.com/2009/03/26/unintended-effects-blue-lights-vs-heroin/">Raph d&#8217;Amico dissects well here</a>), we now have <a href="http://news.bbc.co.uk/1/hi/england/nottinghamshire/7963347.stm"><strong>residents&#8217; associations installing pink lighting to highlight teenagers&#8217; acne and so drive them away from an area</strong></a>:</p>
<blockquote><p>Residents of a Nottinghamshire housing estate have installed pink lights which show up teenagers&#8217; spots in a bid to stop them gathering in the area.</p>
<p>Members of Layton Burroughs Residents&#8217; Association, Mansfield say they have bought the lights in a bid to curb anti-social behaviour. The lights are said to have a calming influence, but they also highlight skin blemishes.</p>
<p>The National Youth Agency said it would just move the problem somewhere else. Peta Halls, development officer for the NYA, said: &#8220;Anything that aims to embarrass people out of an area is not on. &#8220;The pink lights are indiscriminate in that they will impact on all young people and older people who do not, perhaps, have perfect skin. </p></blockquote>
<p>I had heard about this before (thanks, Ed!) but overlooked posting it on the blog - other places the pink lights have been used include <a href="http://news.bbc.co.uk/1/hi/england/lancashire/6197652.stm">Preston</a> and <a href="http://www.thisislondon.co.uk/news/article-23374687-details/In%20the%20pink%20-%20why%20yobs%20with%20acne%20see%20the%20light/article.do">Scunthorpe</a>, to which this quote refers (note the youths=yobs equation):</p>
<blockquote><p>Yobs are being shamed out of anti-social behaviour by bright pink lights which show up their acne.</p>
<p>The lights are so strong they highlight skin blemishes and have been successful in moving on youths from troublespots who view pink as being &#8220;uncool.&#8221;<br />
&#8230;<br />
Manager Dave Hey said: &#8220;With the fluorescent pink light we are trying to embarass young people out of the area. &#8220;The pink is not seen as particularly macho among young men and apparently it highlights acne and blemishes in the skin.<br />
&#8230;<br />
A North Lincolnshire Council spokesman said: &#8220;[...]&#8220;On the face of it this sounds barmy. But do young people really want to hang around in an area with a pink glow that makes any spots they have on their face stand out?&#8221;</p></blockquote>
<p>With the Mansfield example making the news, it&#8217;s good to see that there is, at least, quite a lot of comment pointing out the idiocy of the hard-of-thinking who believe that this sort of measure will actually &#8217;solve the problem of young people&#8217;, whatever that might mean, as well as the deeply discriminatory nature of the plan. For example, <a href="http://www.thisisnottingham.co.uk/news/Putting-squeeze-teens-spot/article-844657-detail/article.html">this rather dim (if perhaps tongue-in-cheek) light in the Nottingham Evening Post</a> has been <a href="http://www.thisisnottingham.co.uk/news/Putting-squeeze-teens-spot/article-844657-detail/article.html#StartComments">comprehensively rebutted by a commenter</a>:</p>
<blockquote><p>Trying to use someone&#8217;s personal looks against them simply because they meet up with friends and have a social life&#8230;</p>
<p>If this is the case then I would personally love to see adults banned from meeting up in pubs, parties and generally getting drunk. I would also love to see something making fun of their elderlyness and wrinkle problems.</p></blockquote>
<p>I don&#8217;t understand why Britain hates its young people so much. But I can see it storing up a great deal of problems for the future.</p>
