Abstract

A system and method for providing dynamic feedback projection from a hand held pointing device is provided. The system includes a hand held pointing device that is capable of two way communication with appliance interfaces associated with appliances that are controllable by the hand held pointing device. The hand held pointer is capable of transmitting signals to the appliance interfaces and receiving response signals from the appliance interfaces. The hand held pointing device further includes a visible light projection apparatus for projecting light onto a remote surface. The projected light is displaced on the remote surface by a light projection modification apparatus such that the projected light creates images corresponding to the response signals from the appliance interfaces.
