Hanger Clinic’s somewhat simpler bebionic hand is already on the market, but, like most such devices, it’s prohibitively expensive. Torri Biddle, a 19-year-old Ohio woman who was born missing the lower part of her right arm, had always dreamed of getting a bionic hand.

What if instead of physically connecting a machine to the nervous system, we could let users control them with eye movements? The method has plenty of science to back it up but has been hard to make user-friendly. Equipment sensitive enough to track eyes precisely is expensive, and can confuse normal behaviors with intentional signals. Aldo Faisal at the Imperial College of London has devised a system that uses two off-the-shelf cameras, instead of one specialized device, and winks, instead of blinks. At a recent conference, the system was put to use to steer a wheelchair.
