[Tempt One] is a graffiti artist who has Lou Gehrig’s disease. He can no longer physically produce art, since his disease has taken his ability to control his arms. His friends, won’t let that be the end of it though. They’re building a visual tracking system to let him work by moving his eye. It seems like it would be very difficult to get any kind of a smooth curve out of eye movement, but the short demonstration video, which you can see after the break, does a decent job, at least for something this early in development. The source code isn’t released yet, but they do plan to do so.  If you wanted to make your own, you could find some info in a past post of ours. We’re guessing they intend to use it with something along the lines of the laser tagging system.

[Alpay Kasal] of LitStudios as come up with an interesting way to use laser pointers as a wireless controller for games and applications. The process is currently being patented, which may explain why [Alpay]‘s blog is a little slim in the details. We doubt they’re doing anything more than just using a camera to track the laser pointer; exactly like laser tagging.

If you’re just itching to get your hands on some wireless game play and can’t wait for this to go commercial you could always just get a Nintendo Wii.
