A new budget device could provide millions of disabled people with a way to interact with computers.
The device works by tracking the user's eye movements through motion sensing technology similar to the Nintendo Wii Remote and Microsoft's X-Box Kinnect. Known as GT3D, the mechanism consists of a pair of glasses with mounted cameras which constantly take pictures of the eyes and calculate the interactions based on what it sees.
"Crucially, we have achieved two things: we have built a 3D eye tracking system hundreds of times cheaper than commercial systems and used it to build a real-time brain machine interface that allows patients to interact more smoothly and more quickly than existing invasive technologies that are tens of thousands of times more expensive," said neurotechnology lecturer Dr Aldo Faisal.
"Millions of people suffering from multiple sclerosis, Parkinson's, muscular dystrophy, spinal cord injuries or amputees could soon interact with their computers and surroundings using just their eyes, thanks to a new device that costs less than £40."
