Using Kinect for eye tracking

"The technology works by figuring out where you’re sitting using a Microsoft Kinect camera, then guessing approximately where your right and left eyes are, and flashing images quickly on the screen targeted at each eye, which creates a 3D image in your brain."

Teenager Builds $300 Open Source Eye-Tracking System

From SlashDot:
"Developed by a 17-year-old electronics and programming whiz from Honduras, the Eyeboard system is a low-tech eyeball-tracking device that allows users with motor disabilities to enter text into a computer using eye gestures instead of a physical interface. This kind of system is not unique — there's plenty of eye tracking interfaces out there — but Luis Cruz has figured out a way to build the full system into a set of glasses for less than US$300, putting easier communication within reach of users in developing countries. He's also releasing the software as open source to speed up development."
