Israeli scientists have created a nose-powered device that severely paralyzed can use to control a computer. A small tube carries the breath of a person to a tiny sensor that detects changes in pressure. A computer translates the puffs into letters, allowing the person to type.
'I have a locked-in patient who sends me e-mails,' says Noam Sobel, a neuroscientist at Weizmann Institute in Israel who’s developing the approach."
