Using Eye Movements For Text & Graphics Input Now Possible
If we take a look at the evolution of input technology, here's how it goes – Initially, you had to type the entire thing using the keyboard; then, you could speak and that is converted to text; further on, you could scribble the word on the touch screen and #-Link-Snipped-#. And now here is the next step - Use your eye movements to see words, numbers or drawings on the screen. Not exactly easy, but with some training people can control their eye movements to represent letters, patterns or numbers.

This technique has already been invented and implemented by Dr. Jean Lorenceau of the Université Pierre et Marie Curie-Paris for his patients. They can draw and write by controlling the eye muscles alone. Eye is not exactly a total voluntary organ. There are so many instances where you just can’t control your eyes, but bringing them under control is the crux of this technique. For that Lorenceau discovered the technique called 'reverse phi motion'.

This technology will be of so useful for those deprived of limb movement, no doubt. Are you wondering what could be the speed of typing this way? Well, according to Lorenceau, after a 90 minute training session you can write at a speed of 20 characters per minute, which is pretty decent. The on-lookers would sure be amazed to see the users frantically moving their eyes in all possible directions. Well, better not try it outside. See a video -
