1. A method for generating an image of an object within a region, comprising: transmitting ultrasound, via a first ultrasonic transmitter of an ultrasonic transmission system, into the region; receiving, via a first ultrasonic receiver of an ultrasonic receiver system, ultrasonic reflections of the transmitted ultrasound from a plurality of sites on the object within the region; generating, via a processor, coarse image data of the object at a first resolution based on the received ultrasonic reflections; identifying a portion of interest on the object based on the coarse image data; receiving electromagnetic radiation from the identified portion of interest on the object; generating fine image data of the portion of interest on the object at a second resolution based on the received electromagnetic radiation, wherein the second resolution is greater than the first resolution; determining a kinematic value associated with the portion of interest on the object based on at least one of the received electromagnetic radiation and the received ultrasonic reflections; and modifying the state of an entertainment device based on the determined kinematic value associated with the portion of interest on the object.
