The technology comprises an eye-tracking device and “smart” software that have been presented July 13, in IOP Publishing’s Journal of Neural Engineering. 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 each, that are attached, outside of the line of vision, to a pair of glasses that cost just £3. The cameras constantly take pictures of the eye, working out where the pupil is pointing, and from this the researchers can use a set of calibrations to work out exactly where a person is looking on the screen.
To demonstrate the effectiveness of the eye-tracker, the researchers got subjects to play the video game Pong. In this game, the subject used his or her eyes to move a bat to hit a ball that was bouncing around the screen — a feat that is difficult to accomplish with other read-out mechanisms such as brain waves (EEG).
Dr Aldo Faisal, Lecturer in Neurotechnology at Imperial’s Department of Bioengineering and the Department of Computing, is confident in the ability to utilise eye movements given that six of the subjects, who had never used their eyes as a control input before, could still register a respectable score within 20 per cent of the able bodied users after just 10 minutes of using the device for the first time.
