Eye-eye coordination: no hands required

Researchers from Imperial College London have fashioned a commercially viable eye tracking device. This simple innovation could soon allow victims of paralysis to interact much more effectively and easily with electronic devices. The glasses use two inexpensive video-game cameras to track eye movement, even capable of working out how far in the distance a user is looking.

Dr Aldo Faisal, Lecturer in Neurotechnology at Imperial, said: "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."
