A real-time 3D motion tracking system
… is known as gaze control. The primary goal of motion tracking is to keep an object of interest, generally known as the visual target, in the view of the observer at all time. Tracking can be driven by changes perceived from the real world. One obvious change introduced by a moving object is the …
