    Markerless Laser-based Tracking for Real-Time 3D Gesture Acquisition



    We describe here our latest work on a prototype finger-tracking system based on a wide-angle photodetector and an eye-safe laser diode whose beam is steered by a pair of micro-mirrors. Essentially, it is a smart rangefinder scanner that instead of continuously scanning over the full field of view, restricts its scanning area, on the basis of a real-time analysis of the backscattered signal, to a very narrow window precisely the size of the target. The complexity of the whole setup is equivalent to that of a portable laser-based barcode reader.
