Kriteria Web Usability

Pada evaluasi web usablity kali ini akan menggunakan Nielsen heuristic untuk perancangan antarmuka dan evaluasi (http://www.useit.com/papers/heuristic/heuristic_list.html).

Heuristic	Description
Visibility of system status	The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.
Match between system and the real world	The system should speak the users’ language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.
User control and freedom	Users often choose system functions by mistake and will need a clearly marked “emergency exit” to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.
Consistency and standards	Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.
Error prevention	Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.
Recognition rather than recall	Minimize the user’s memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.
Flexibility and efficiency of use	Accelerators — unseen by the novice user — may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.
Aesthetic and minimalist design	Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
Help users recognize, diagnose, and recover from errors	Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.
Help and documentation	Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.

1. Visibility of system status

Tidak ditemukan masalah

2. Match between system and the real world

Masalah Ditemukan: Metode pembayaran yang tidak sesuai dengan tempat asal pembeli tiket. Disini contohnya seseorang yang berangka dari Singapura, ditawarkan metode pembayaran melalui ATM Bank di Indonesia.

Tingkat Masalah: Medium

Solusi Masalah: Hilangkan metode pembayaran yang tidak sesuai dengan tempat asal pengguna.

3. User control and freedom

Masalah Ditemukan: Penggunaan Javascript yang berlebihan. User yang mematikan fungsi javascript di browsernya tidak dapat melakukan navigasi dengan baik dan memesan tiket.

Tingkat Masalah: Tinggi

Solusi Masalah: Kurangi penggunaan Javascript pada fungsi-fungsi utama website. Buat secondary navigasi berbasiskan text pada bagian footer.

—

Masalah Ditemukan: Penggunaan Breadcumb yang tidak sesuai dengan standar. Breadcumb tidak dapat di klik untuk mengizinkan pengguna kembali pada halaman sebelumnya berdasarkan tingkat hirarki.

Tingkat Masalah: Medium

Solusi Masalah: Buat Breadcumb dapat di klik untuk memudahkan kembali ke tahap sebelumnya. Tanpa harus menekan tombol kembali pada bawah halaman.

Pendahuluan

“Make it as simple as it needs to be. But no simpler. “ – Albert Einstein

Web usability adalah segalanya mengenai perancangan dan pembuatan website yang membantu pengunjung untuk menyelesaikan tujuan nya dengan cepat dan efisien. Dengan website yang usable, lembaga atau perorangan dapat mendapatkan keuntungan yang besar. Menurut IBM setiap £1 yang diinvestasikan untuk meningkatkan usability akan mengembalikan £10 sampai £100. Bahkan penelitian useit.com merombak ulang usability web dapat meningkatkan sales/konversi sampai 100%.

Pada dasarnya Web Usability mempunyai empat point penting:

1. Website anda harus mudah di navigasi

Seiring waktu pengunjung sudah terbiasa dengan suatu layout atau frase di internet, contohnya:

Logo berada di pojok kiri atas dan link back kehalaman home
Terminologi “About Us” digunakan untuk informasi organisasi
Navigasi berada pada tempat yang sama pada setiap halaman dan berdekatan dengan isi
Segala sesuatu yang berkelap-kelip atau ditempatkan diatas logo biasanya iklan

Diatas merupakan contoh yang umum. Masih banyak contoh lainnya untuk meningkatkan website usability. Pengembang web sebaiknya jangan melihat dengan sebelah mata konvensi ini karena semakin lama pengguna terbiasa dengan suatu hal. Melanggar konvensi ini anda mungkin mendapatkan website dengan usability yang rendah dan pengguna yang tidak puas.

2. Halaman dapat dibuka dengan cepat

8.6 detik adalah waktu maksimum pengguna mau menunggu suatu halaman terbuka (weboptimisation.com). Pada september 2006 sekitar sepertiga pengguna internet di Inggris terkoneksi ke Internet menggunakan Dial-up(statistics.gov.uk). Jadi sangat penting sebuah website memiliki waktu load yang cepat untuk memenuhi usability yang baik.

3. Informasi harus mudah didapatkan

Kita membaca halaman web berbeda dengan media cetak. Secara umum kita membacanya dengan teknik skimming daripada kata-per-kata. Ketika kita membaca halaman web beberapa hal harus mencolok, seperti:

Heading
Link Text
Bold Text
Bulleted List

4. Jangan halangi pengguna

Jangan halangi pengunjung web dari navigasi dengan cara yang ia inginkan:

Disable right click
Disable back button
Penggunaan frame
Kewajiban untuk sign up terlebih dahulu sebelum dapat melihat suatu informasi

Banyak cara website menghalangi penggunanya, sehingga merusak usability-nya.

Sekilas Lion Air

Lion Air adalah sebuah perusahaan penerbangan swasta lokal yang berbasiskan di Jakarta. Selain melayani penerbangan lokal, Lion Air juga melayani penerbangan Internasional, seperti ke: Malaysia, Singapore, Vietnam, dan Saudi Arabia. Lion Air termasuk perusahaan penerbangan yang cukup sibuk melayani 42 rute dengan 226 penerbangan setiap harinya.

Sudah semestinya Lion Air memiliki sebuah website (http://www2.lionair.co.id/) yang melayani kebutuhan pelanggan nya. Mulai dari korporat yang mencari informasi perusahaan hingga individu yang ingin memesan tiket. Sehingga website Lion Air bertindak sebagai company profile dan costumer service. Untuk memenuhi kebutuhan tersebut sudah sewajarnya web Lion Air mempunyai web usability yang baik dan dapat diandalkan. Sehingga dapat memuaskan pelanggan dan profesionalitas di mata korporat dapat terjaga.

Tetapi sayangnya banyak temuan yang mengurangi usability dari web lion air. Sehingga perlu adanya suatu pengukuran dan testing terhadap usability web Lion Air. Tentu saja, temuan-temuan dalam penelitian ini hanya permulaan dan tidak mencakup seluruh point dalam penilaian web usability. Bagaimanapun juga, sebagai salah satu pengunjung setia website tersebut, saya rasa perlu adanya perbaikan-perbaikan dalam beberapa hal. Rasanya ini akan membantu pihak terkait untuk mengevaluasi kembali website mereka dalam hal usability.

Apple VS Adobe

Rendy — Thu, 27 May 2010 01:36:55 +0000

Well, I have been living under the rock lately because I just aware Tech war is on between Apple and Adobe a couple days ago, which in fact have been going around for quite sometime.

The problem can be traced back to lack of Flash on Apple mobile devices. The "war" is officially on by Steve Jobs when he published his Thought on Flash on Apple website. According to him Apple decision to abandon Flash is based on technology issues. He claims there’s reliability, security, performance, and technical issue. For starter according to Apple, Flash is the number one reason Macs crash and according to Symantec in 2009 Flash had the worst security records. For technical issue Flash has proven not performed well on mobile devices and to save power mobile devices must decode video in hardware, decoding it in software simply drain much power which mobile devices simply don’t have much. More over current Flash is not playing nice with touch interface.

Adobe co-founders responded in an open letter that was published in newspaper ads as well as their website. Adobe responded Jobs claims:

Adobe Flash Player runtime originally created as a technology for tablets with touch interface. Existing content that developed with mouse input in mind, Flash Player will automatically convert touch events to mouse events. For new content that specifically developed for touch input, Flash 10.1 will provide a complete set of multitouch and gesture APIs.
Flash Player 10.1 will include support for hardware-accelerated video playback from mobile devices to desktop environments. This translate to better battery life.
Flash player is part of a rich ecosystem of both open and proprietary technologies.

While I’m not big fan of Flash, I believe HTML5 and Flash will play along their parts in the future. I believe there’s place for Flash so with HTML5.

How to make a panorama picture using only cellphone camera

Rendy — Mon, 24 May 2010 05:29:51 +0000

It’s been long time since my last post. I’m quite busy lately with my college work. But finally I have sometime off, now I want to share some knowledge. Being poor college student and can’t afford $1000 camera doesn’t mean you can’t make a good panorama picture. I will show you how to make one with just cellphone camera (any camera will do) and two software (Windows Live Photo Gallery and Photoshop CS5). Photoshop CS5 is optional, but if you want to fix the picture with relative ease, there’s new feature in Photoshop CS5 called Content Aware Fill.

Okay, first you need several pictures of same location in different angle. In my example I take pictures inside of my university mosque.

Nice picture right? FYI this picture taken with Nokia 6288 with 2 Megapixel camera. A very outdated phone, but still do it’s job.

We need to stitch the picture together to make a panoramic looks. Open Windows Live Photo Gallery, it’s freeware courtesy of Windows Live.

Select the picture you want to stitch together, and from the toolbar choose Make and Create Panoramic Photo. Wait several seconds till your picture ready and save the results.

You’re almost done!. The black corner is the angle that is not included in source picture. You can fix that by take the picture of that angle or just let Photoshop CS5 fill the blank.

Open your panoramic picture with Photoshop CS5

Select the black section with Magic Wand Tool, go to Edit and choose Fill (Shift+F5).

Make sure you use Content-Aware and click OK. Let’s Photoshop do it’s magic.

Done!.

5 assessment criteria for user interface : Windows Phone 7 Case

Rendy — Wed, 24 Feb 2010 04:57:19 +0000

Although there is many way to assess user interface, but since my class project only asks for five most important criteria according to individual. So, this is most important criteria in my opinion required in a interface/device. In this case I’m assessing recently unveiled Windows Phone 7 from Microsoft, that I have introduced on last post.

1. Ease of Use

One of the great thing about Windows Phone 7 is easy to use. Phone divided into several parts of the main menu: People, Pictures, Games, Music + Video, Marketplace and Office. The menu is like a big application with broad panorama, which is not enough on one screen so the user must shift to the right and the left to see the whole application.

Windows Phone 7 has big, oversized, beautiful, bold, clear, and interactive icon, unlike every other phone in the market the menu filled with square arranged in a pattern like 4×4 or so. So it made this phone made easier to use, with big clear icon you no longer need to navigate carefully where you want to go, just a simple look at the screen and a touch. Moreover, the icon is dynamically updated according the application. So for instance, you have three new messages, you’ll be presented with number ‘3’ at top of the icon.

What makes Windows Phone 7 is interesting is it is integrated with live, real-time data seamlessly integrated, with smooth and more natural interface. The start screen is live, meaning it will dynamically updated with fresh content like weather, status updates, photos from facebook and you can totally customize it. So, you don’t have to open separate application just to see what your friend up to, just a simple glance at the screen. This is dream comes true for social networking geek.

2. Ergonomic

Office and Email

Yes, there will be an office application on Windows Phone 7. It will be connected to Cloud and can be synced to corporate server. So that means business people can read, create and edit their work while on the go.

The Outlook email is stunning, according to some people it’s much better than reading email on a BlackBerry. Text is huge, gorgeous, readable, and support Microsoft Exchange. Business people should be happy.

Browser

There will be Internet Explorer. Although the rumour says it’s going as fast as Mobile Safari. But at least it support multitouch. Bing and Bing Maps are built into the phone as default search engine and map provider.

3. Easy to Navigate

Microsoft radically upgraded the look and feel Windows Phone 7 from previous Windows mobile series. Gone the day when you need stylus to navigate the phone. Now it featuring unusual interface element that found on other phone in the market: Interface elements that run off the screen, oversized dynamically updated icon, fresh start screen. Although integrating unusual aspect, yet it’s still easy to navigate.

4. Easy to Learn

“Cognitive load” is one of the criteria to rate user interface. To use sophisticated programs like Windows Phone 7 users must drop all their OS concept, because Windows Phone 7 is all new experience for them. It’s necessary to provide smallest learning curve for users, because most of the time users don’t have necessary time to read manual. Human have limited capacity of working memory, users can only hold five to nine chunks of information simultaneously. Users may feel overwhelmed by numerous options that increase the cognitive load.

Thankfully, Windows Phone 7 provides original and what one Nike designers calls an “authentically digital” and “chromeless” experience. The whole looks is oversimplified which is good thing for this phone since the previous windows mobile series is famous for absurd menu and hard to use.

5. Information Representation

Microsoft has done a good word to put many features in Windows Phone 7 is an understandable form. The interface is elegantly designed to show as much information as possible to users. Users certainly able to find all the information they want in single screen.

For example, ‘people’ screen you not only can see your contacts but also their status update and photos from social networking sites.

In Music+ Video you’ll be able to see all your collection of music, video, podcast. More over you can opt to listening to radio or visiting a integrated marketplace where you can buy music or video.

Windows Phone 7 Mobile User Interface Review

Rendy — Wed, 17 Feb 2010 05:28:51 +0000

After beaten by Apple and Google in mobile operating system arena, Microsoft finally reveal their new Operating System for smart phone which inevitably called Windows Phone 7. Although technical details is still sparse and Microsoft didn’t reveal much about what changes except the obvious glossy new user interface. Let’s not talk about technical details, new kernel, the next SDK, or developer policies. Let’s just admire the new user interface which I admit looks very much alike Zune/Zune HD.

In my opinion the interface is much more better than current iPhone and basically every other phone in the market where thumbnail-sized glossy-looking icons arranged in a pattern. Instead Microsoft developer opt to using oversized set of bright squares that fill the screen. Beautiful user interface combined with crisp wide screen made this phone aesthetically pleasant yet very practical. It’s combining unusual practices like big size text, interface elements that run off the screen, oversized text and graphics, flipping, panning, scrolling, zooming from screen to screen. This made iPhone user interface feels conservative by comparison.

Overall it’s very fun and playful phone to use, yet it’s still maintain “corporate fell” since there will be a new Office and app store.

Linux Tips : Setting Java programming environment in Ubuntu Linux

Rendy — Fri, 01 Jan 2010 08:47:35 +0000

I do a lot of programming in Ubuntu Linux. A couple months ago I started to learn JAVA, previously I have used to program in C/C++ which fortunately Ubuntu is already built in GCC (GNU C Compiler) so everything works out of the box. Unfortunately the case is not the same as JAVA, Ubuntu is not shipped with Java JDK/JRE. So, you must install everything by yourself.

I found out one of my favourite IDE in Windows that support JAVA programming is also available on Linux, it is NetBeans. Netbeans is free Integrated Development Environment (IDE) that supports a lot of languages, including Java, JavaScript, PHP, Python, Ruby, C/C++ and more. NetBeans is written in Java and runs with Java Virtual Machine (JVM) installed. For Java development functionality you must install JDK first, but for other languages you can just install JVM.

Install JDK/JRE Ubuntu Linux

Okay, let’s start with installing JDK and JRE. There are two ways Installing JDK and JRE, the easy way is from Synaptic Package Manager and the hard way is install from .bin file. Installing from Synaptic Package Manager is the best way when you have internet connection or any access to repository (DVD, server, etc). But if your computer don’t have any access to repository server, you can download .bin file from Sun Website from other computer and install it on the computer that you want.

Option 1
First lets start with the easy way, install from Synaptic. Make sure you have the Multiverse repository enabled.

System > Administration > Software Source > Select Multisource > Close

Open your terminal and type the following command to install JDK and JRE

$ sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk

Wait till it download and install, depend on your connection it should take several minutes.
Make sure the correct version is used by using this command

$ sudo update-java-alternatives –s java-6-sun

—

Option 2

For those who want to install the hard way, first download JDK and JRE from Sun. You will get .bin file.

Open your terminal, then go to directory where the download file is, and make sure the file is executable.

cd /directory/where/you/download/file
sudo chmod +x filename

Install the file with this command

sudo ./filename

Make sure the correct version is used by using this command

$ sudo update-java-alternatives –s java-6-sun

Install Netbeans Ubuntu Linux

Option 1
Download Netbeans from here and save it to your computer. Let’s say the file is called “netbeans-6.8-ml-linux.sh”. Run your terminal and change directory to where you download the file.

$ cd /direcory/where/you/download/file

Make sure the file is present by using ls command. Finally execute the following command

$ sudo ./netbeans-6.8-ml-linux

After completing command, you will see installer that will install NetBeans into /opt directory. Finish!.

—

Option 2
Alternatively you can also install using Synaptic Package Manager, just execute the following command.

$sudo apt-get install netbeans

Finish!.

File Storage and Retrieval

Rendy — Tue, 29 Dec 2009 16:50:16 +0000

Information stored in a mass storage system is conceptually grouped into large units called files. A typical file may consist of a complete text document, a photograph, a program, a music recording, or a collection of data about employees in a company. We have seen that mass storage devices dictate that these files be stored and retrieved in smaller, multiply byte units. For example, a file stored on magnetic disk must be manipulated by sectors, each of which is a fixed predetermined size. A block of data conforming to the specific characteristics of a storage device is called a physical record. Thus, a large file stored in mass storage will typically consist of many physical records.

In contrast to this division into physical records, a file often has natural divisions determined by the information represented. For example, a file containing information regarding a company’s employees would consist of multiple units, each consisting of the information about one employee. Or, a file containing a text document would consist of paragraph or pages. These naturally occurring blocks of data are called logical records.

Logical records often consist of smaller units called fields. For example, a logical record containing information about an employee would probably consist of fields such as name, address, employee identification number, etc. Sometimes each logical record within a file is uniquely indentified by means of a particular field within a record. Such as identifying fields is called a key field. The value held in a key field is called a key.

Logical record sizes rarely match the physical record size dictated by a mass storage device. In turn, one may find several logical records residing within a single physical record or perhaps a logical record split between two or more physical records. The result is that a certain amount of unscrambling is associated within a retrieving data from mass storage systems. A common solution to this problem is to set aside an area of main memory that is large enough to hold several physical records and to use this memory space as a regrouping area. That is, a blocks of data compatible with physical records can be transferred between this main memory area and the mass storage system, while the data residing in the main memory area can be referenced in terms of logical records.

An area of memory used in this manner is called a buffer. In general, a buffer is a storage area used to hold data on temporary basis, usually during the process of being transferred from one device to another. For example, modern printers contain memory circuitry of their own, a large part of which is used as a buffer for holding portions of a document that have been received by the printer but not yet printed.
