FreeTrack, an open source head-tracking program

Computers & Mobile

FreeTrack is an open-source head tracking program for Windows. Using a webcam (or WiiMote) and some LEDs, the software is able to determine where your head is and where you are looking. It appears to be used mostly for gaming, but could come in handy if you need a simple way to track things in your next project. [via nicholaswallen]
