It's hard to imagine a computer you can control with your eyes, but the technology exists and should be available on store shelves in the next couple of years.
Swedish company Tobii, a pioneer in eye tracking technology, has come up with a way to control the screen of a laptop or desktop with your eyes that's actuate within a quarter of an inch.
The technology was first made available to people with handicaps, but it's progressed and will soon be available to the general public.
Pretty soon you can read e-mails with your hands behind your head, scrolling up and down with your eyes. Or if you're playing FIFA soccer you can decide where to shoot the ball by looking at the upper left corner of the goal.
