Eye-tracking interface

Technology is being developed to allow people with severe motor disabilities to play 3D computer games like World of Warcraft using only their eyes.

Since the 1990s, gaze technology has helped people with conditions such as motor neurone disease (MND), cerebral palsy and other "locked-in syndromes" to control 2D desktop environments and communicate using visual keyboards.

Users typically guide a cursor with their eyes, staring at objects for a time to emulate a mouse click. But that is too laborious to let users to match the speed and accuracy of real-time 3D games, says lead researcher on the project, Stephen Vickers, of De Montfort University, Leicester, UK. - NewScientist
