Imagine not being able to move a mouse or use a keyboard to control your computer. Frustrating, right? A company Timothy Lord found at CES named Eyetech has a solution for this problem: an eye tracker system that can control your computer or TV (or whatever) purely through eye movements. This isn't something you buy on a whim; the system costs $3000. That's a lot, but Eyetech claims they were the first ones to produce a high-accuracy eye tracker for less then $20,000. Obviously, this is a boon to profoundly disabled people. But Eyetech's Keith Jackson says, in the video, that they also have customers who use Eyetech instead of a mouse because of carpal tunnel syndrome, and that with voice recognition and on-screen keyboards -- and Eyetech, of course -- you can use your computer without (literally) lifting a finger.
