A scientist has created a budget device that can control a computer by tracking eye movement after stumbling on a £9.95 web camera being sold with a games console – a huge saving from the £20,000 that a similar apparatus used for medical research would have cost at the time.
German neuroscientist Dr Aldo Faisal was setting up a laboratory at Imperial College in London when he made the chance discovery.
Faisal and his team reconfigured two of the cameras and fixed them to a harness which attaches to the head, making a £43 device that opens up the use of computers to the 6 million people in the UK with restricted hand movement.

This new approach to computer control is interesting, especially if the developer can keep the cost down.

Well it is a huge difference from the £20000 for the medical instrument.

That's fascinating. I love when complex technology gets cheaper so that more people can experiment with it.
