Disabled patients could soon control computers with eyes

Washington, July 13 : Researchers have developed a device that could help millions of people suffering from multiple sclerosis, parkinson's, muscular dystrophy, spinal cord injuries or amputees to soon interact with their computers and surroundings using just their eyes.

Composed from off-the-shelf materials, the new device that costs less than 40 pounds can work out exactly where a person is looking by tracking their eye movements, allowing them to control a cursor on a screen just like a normal computer mouse.

The technology comprises an eye-tracking device and "smart" software.

Researchers from Imperial College London demonstrated its functionality by getting a group of people to play the classic computer game Pong without any kind of handset. In addition users were able to browse the web and write emails "hands-off".

The GT3D device is made up of two fast video game console cameras, costing less than 20 pounds each that are attached outside of the line of vision, to a pair of glasses that cost just 3 pounds.
