Lego head tracking

lego_tracking

[Epoch] Sent in this simple head tracking project using Lego pieces. He’s made a custom mount to hold 3 Lego light sensors on a baseball cap. Then, after modifying his webcam for IR with some floppy disk scraps, he loads up the free-track software and can control his games. For convenience, he has programmed the Lego Nxt to only turn on the lights while he’s holding a contact sensor. You can see it in action after the break. This appears to be very similar to [Johnny Lee's] head tracking. Judging by the video, it’s not as smooth though.

What? If anything, the Lego bricks make the project even cooler.

Lego is not necessary at all, you can rig this with 3 infrared LEDs, and a battery pack from radio-shack, and it wouldn’t require $200 Lego Robotics kit. It must be an April’s fool joke.

+2. 1 to negate your -1 and 1 just because like bacon makes anything you eat better, all hacks are better hacks when you use legos.

Legos >= any other platform.

If you can do it, good for you.

If you can do it with lego mindstorms, even better.

I think this is unique in that there’s really nobody that wants to be seen with this at all on this planet. (I assume the inventor HAD to though) :)
