Claim:
1. A system for determining velocity data of an object within a region, comprising: a position module configured to determine a relative position of an object within a region; an ultrasonic transmitter configured to transmit ultrasound into the region; an ultrasonic receiver configured to receive an ultrasonic reflection of the transmitted ultrasound from a site on the object within the region; a shift module configured to detect a shift of the ultrasonic reflection received by the ultrasonic receiver relative to the transmitted ultrasound; a velocity calculation module configured to calculate a first velocity component associated with the site based on the detected shift of the received ultrasonic reflection; a modification module configured to modify the state of an entertainment device based on the relative position of the object and the first velocity component of the site; wherein the ultrasonic receiver is further configured to: a mapping system configured to:
