Laser Keyboards

2012-10-31T01:59:00.000-07:00

For many users who need full-sized keyboard functions on the go but don't want to haul one around on vacation or work trips, laser keyboards can provide a solution. These keyboards provide a full-sized set of virtual keys projected onto a surface, giving you the ability to type anywhere there is a flat surface

Technology

Step 1: Template creation (Projection Module)

A template of the desired interface is projected onto the adjacent interface surface. The template is produced by illuminating a specially designed, highly efficient holographic optical element with a red diode laser.

Step 2: Reference plane illumination (Micro-illumination Module TM)

An infra-red plane of light is generated just above, and parallel to, the interface surface. This light is invisible to the user and hovers a few millimetres above the surface. When the user touches a key position on the interface surface light is reflected from this plane in the vicinity of the key and directed towards the sensor module.

Step 3: Map reflection coordinates (Sensor Module)

Reflected light from user interactions with the interface surface is passed through an infra-red filter and imaged on to a CMOS image sensor in the sensor module. Custom hardware embedded in the sensor chip (the Virtual Interface Processing Core TM) then makes a real-time determination of the location of the reflected light. The processing core can track multiple reflection events simultaneously and can thus support both multiple keystrokes and overlapping cursor control inputs.

Step 4: Interpretation and communication (Sensor Module)

The micro-controller in the sensor module receives the positional information corresponding to the light flashes from the sensor processing core, interprets the events (e.g. keydown, keyup, mouse or touchpad control etc..) and communicates them through an appropriate interface to external devices.

Arc Mouse Concept

2012-09-02T18:36:00.000-07:00

If you always happen to struggle with a computer mouse putting it on your leg or on the curved arm of your favorite chair, this new concept is just for you. A new mouse concept, the Arc, may be something you could use. It has been specifically created to be used on curved surfaces.

The Arc mouse has been created by Seunghoon Shin and Chang Seok Kim. It’s an entry into the 2012 IDEA Awards. The most significant thing about the Arc mouse is that it will also do its job pretty well on flat surfaces making it a great all round design.

The Arc mouse is also provided with wireless connectivity and will help you work in those inconvenient situations when you commute or are a little short of flat desk space for a conventional mouse.

Sadly, the Arc mouse is still just a concept at the moment so don’t expect it to arrive in stores any time soon. To make it reality, you should visit the Kickstarter website if you think it’s something you could benefit from.

Nokia Kinetic Bendy Phone

2012-09-01T02:25:00.000-07:00

Unlike many smart phone manufacturers, Nokia keeps inventing and trying new features rather than simply copying features from another systems. Nokia recently presented their latest experiment – Nokia Kinetic Bendy Phone. Special thing about this phone is flexibility. Yes, you can twist it, squeeze it or flex it.

The prototype Nokia Kinetic Device, including its display, can be flexed across both the vertical and horizontal planes -- with bending and twisting motions controlling the interface. If you bend the screen towards yourself, it acts as a selection function, or zooms in on any pictures you're viewing. In music mode,
you can navigate, play and pause with the tactile interface. Twist forward to scroll through files and the twisting action controls the speed. The more you twist, the faster you scroll.

Nokia have lot of hopes with this new invention and I must say they are right about it. Some simple use cases could be the countries where you got to wear gloves to survive in cold but can not use touch screen effectively due to rough surface of finger covered glove. Bendy do not have any buttons and that makes it a waterproof device.

Step 6: Find the <head> tag by using "Ctrl + F" and copy and paste below code after the <head> tag.

type='text/javascript'></script>

$(window).ready(function(){

Classic “All Programs” Menu in the Start Menu in Windows 7

2012-08-30T04:29:00.001-07:00

There are a lot of new users to Windows 7 who are not happy with the new Start Menu and wish they could revert to the Classic menu. Here is how to at least get back the Classic “All Programs” Menu.

Let’s take a look at Classic Start Menu in XP

Note: This trick uses a Registry hack so you’ll want to make sure you back up the Registry before making any changes.

STEPS:

1. First click on the Start Menu and type regedit into the Search box and hit Enter.

2 Now we need to navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders. Double-click on Favorites on the right side…

3. Now change the Value data to the following and click OK:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs

4. Next scroll down a bit further to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders. Double-click on the Favorites entry.

5. Again we need to edit the Value data to:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs

6. After making the changes close out of the Registry Editor and right-click on the Start Menu and select Properties.

In the Taskbar and Start Menu Properties Window click on the Start Menu tab then click on the Customize button.

7. Scroll down and click the box next to Favorites menu, click OK, and reboot your system.

8. When you come back from the Restart you will see Programs on the right side of the Start Menu and have a list of All Programs similar to that of XP.

While it’s not quite the same as the good old XP days, if you’re looking to get the All Programs Menu back, this Registry hack will do the trick without installing 3rd party software.

Hide the files behind JPEG image

2012-08-29T06:03:00.001-07:00

Hiding files by some sort of software has been a very common way till now, but if you are looking for something different you can do it by hiding a file behind a jpg image.
In order to accomplish this task, you will need to have either WinZip or WinRAR installed on your computer. You can download either of these two off the Internet and use them without having to pay anything.

Step 1. Create a folder anywhere in your PC e.g. C > Softslas and keep all the files you want to hide as well as the jpg image you will use to keep that files in.

Step 2. Just select all the files you want to hide, and by right clicking on them select the option of add them to a compressed ZIP or RAR file. Only compress the files you want to hide, not the jpg image. Lets name it as “Secret.rar”.

You’ll see that there is those files, the jpg image and a compressed archive named Secret.rar inside the folder Softslas.

Step 3. Now i will tell you how to make the trick. Click on Start menu, click Run and type “cmd” (without the inverted commas), press enter and you will see the command prompt window has been opened. Type cd to get into the root directory and again type cd followed by the folder’s name you want to hide i.e. “cd Softslas”. Now you are inside the directory C > Softslas>.

Step 4. Suppose the jpg image have name of “Image.jpg”. Type the following line

copy /b Image.jpg + Secret.rar Image.jpg

(Omit the quotes) and press enter.You will get a response in the command prompt like below.hide-files-behind-image2

Be sure that the compressed file has the extension of . ZIP or .RAR. As I have heard about some problems people faced while using WinZIP, I recommend you to use WinRAR instead of WinZIP.

That’s all you have to do. Now you have a jpg image with your secret files inside it. If you check the picture size you will see it has been increased by same size that was of the compressed archive. Now you can the delete the . RAR file and the file1 and file2.

How to access the hidden files

Just right click on the file and chose open with WinRar.Then you can see the file you hide behind the picture. Another way to access the hidden file is that just change the extension of the file to .RAR and open the file using WinRar and then extract them.
