Pico Projector Applications

Detecting false bodies is a common problem in gesture recognition. It is becoming a harder problem for the projection displays. This video introduces a novel secure control technique for mobile projectors , which combines retroreflectors, a light source and a processing unit. Retroreflectors reflect incident  light back toward the direction of the light source, therefore the technique is based on a relatively simplistic algorithm which can detect multiple bodies real time and at high refresh rates.
