Colour-coded keyboards

 

 

 



Touch sensitive keyboard

 

 The QWERTY keyboard display is projected onto a non-reflective surface, and detects the exact location where you touch the keyboard, relaying the keystroke back to your computer.

The keyboard is portable too. It comes with its own case, is only 9 x 3.5 x 2.5cm in size, and can run for 120 minutes on batteries, or can use its own mains adaptor.

The manufacturers claim that it will work in a standard-lit room, but I’m sure you’ll agree that it looks best with the lights turned down low. Apparently there are sound-effects too, which has me drooling, I have to confess.

The virtual keyboard can operate at 400 keystrokes a minute, which is more than fast enough for this two-fingered hack, but could be an issue for some. Personally, I’d rather break my fingers to slow myself down a little, rather than miss out on having one of these!

This is a video that show you how this type of keyboard works :)

 

 



I'm so sorry it took me a long time to post but I was really busy,studying for November tests.

Anyway, at the moment in computer studies we are doing Input and Output devices. An example of input device is the keyboard. There are special purpose keyboards like pressure sensitive keyboard,touch sensitive keyboard and the color-coded keyboard.
