The PrimeSensor is a low-cost, plug and play, USB-powered device that can either sit on top or next to a television screen or a monitor, or be integrated into them. It generates real-time depth, color and audio data of a scene. It provides the algorithmic framework for development of rich natural interaction applications design on one hand, and games development on the other. It works in all room lighting conditions, and does not require the user to wear or hold anything, does not require calibration or computational resources from the host’s processor.
