A $62 device could help people with physical disabilities operate their computers hands-free—or play a game of "Pong"
Researchers from Imperial College London published their results of the eye wear in July in the Journal of Neural Engineering . Their new device, the GT3D, consists of two fast video game console cameras that are attached, outside of the line of vision, to a pair of glasses. Users move the cursor by moving their eyes to where they want it to be and they “click” by winking one eye. The GT3D is calibrated to track eye movements in a 2D space as well as see how far away test subjects were looking. This 3D gaze will allow the researchers to create an even more advanced device which could be used to help patients move around in a wheel chair by looking where they want to go, again without their hands. These glasses could help those who suffer from a variety of disabilities interact more effectively with computers.
