1. An entertainment device for generating an image of an object within a region, comprising: an ultrasonic transmitter that transmits ultrasound into the region; an ultrasonic receiver that receives an ultrasonic reflection of the transmitted ultrasound from a plurality of sites on the object within the region; a first imaging module that generates coarse image data of the object at a first resolution based on the received ultrasonic reflections, wherein the object includes one or more human controllers of the entertainment device; an identification module that identifies a portion of interest on the object based on the generated coarse image data; an electromagnetic radiation transmitter that transmits electromagnetic radiation into the identified portion of interest of the object within the region, wherein the identified portion corresponds to a particular body part of one of the human controllers; an electromagnetic radiation receiver that receives electromagnetic radiation from the identified portion of interest on the object; a second imaging module that generates fine image data of the portion of interest on the object at a second resolution based on electromagnetic radiation received by the electromagnetic radiation receiver, wherein the second resolution is greater than the first resolution; a compressed sensing module that enhances the fine image data using compressed sensing techniques; a kinematic determination module that determines a first kinematic value associated with the portion of interest on the object based on at least one of received electromagnetic radiation and received ultrasonic reflections; and a modification module that modifies a state of the entertainment device based on the first kinematic value associated with the portion of interest on the object.
