Researchers develop ultra low cost 3D gaze estimation
July 13, 2012 // Nick Flaherty
Reseachers at Imperial College, London, have developed a system for controlling computers with gaze detection that costs just €50.
Composed from off-the-shelf materials, the new device 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. The researchers 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.
"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 Dr Aldo Faisal, Lecturer in Neurotechnology at Imperial's Department of Bioengineering and the Department of Computing. "This is frugal innovation; developing smarter software and piggy-backing existing hardware to create devices that can help people worldwide independent of their healthcare circumstances."All news
