Hand tracking in bimanual movements

A general hand-tracking algorithm is presented for tracking hands in bimanual movements. The problem is approached from a neuroscience point of view. Using a dynamic model and some motor control phenomena, the movement of the hands during a bimanual movement is recognised. By capturing the hands velocities and recognising the bimanual synchronisation, the hands are tracked and reacquired in different types of movements. This includes tracking hands when they are separated, and reacquiring them at the end of hand-hand occlusion. Different applications are demonstrated including active vision where the camera view direction and position change.
