Claim:
1. A method of tracking motion of a target object for gesture control of a system by determining positional information of the target object moving in a region of space within range of a light sensitive sensor, the method including: scanning the region of space monitored by the light sensitive sensor by selectively illuminating respective directionally oriented non-coplanar light sources of a plurality of directionally oriented non-coplanar light sources that (i) are mounted to a single non-coplanar surface and (ii) have at least some overlapping fields of illumination; measuring, using the light sensitive sensor, one or more differences in an intensity of returning light emitted from the respective directionally oriented non-coplanar light sources and reflected from the target object as the target object moves through the region of space; determining positional information of the target object based on, at least, a first position in space at a first time t determining a movement of the target object in response to a difference in the determined positional information of the target object at the first time t recognizing gesture control in response to the determined movement of the target object.
