Meta Perception: Human Interface / Smart Laser Scanner »

The problem of tracking hands and fingers on natural scenes has received much attention using passive acquisition vision systems and computationally intense image processing. We are currently studying a simple active tracking system using a laser diode (visible or invisible light), steering mirrors, and a single non-imaging photodetector. The system is capable of acquiring three dimensional coordinates in real time without the need of any image processing at all.
