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.

  1. 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. +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.

  3. Legos >= any other platform.

    If you can do it, good for you.

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

  4. 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) :)
