Chris Rojas cooked up some dazzling interactive eye candy using IR-bot tracking + video projection –
I just finished installing some hardware for SparkFun’s robot tracking system. It’s sort of a mixed reality system combining home made robots and hacked together control systems, IR tracking and sweet high res projections from above.
It uses a modded PS3 eye, an ultra-short throw projector mounted above the ceiling, Community Core Vision and Processing running MSAFluid.
The robots can consist of pretty much anything, all that the robots need to be tracked is a simple IR LED pointing upward towards the modded PS3 webcam which now only sees infrared. In this case Tim has attached a small throwy style cell battery, resistor, switch and IR LED together and literally just taped it to his robot.
