REMOTE CONTROL POINTING TECHNOLOGY

摘要

A pointing device (10) is disclosed comprising a light emitter (65) for emitting a plurality of light beams (100) in mutually different controlled directions. The light beams are individually identifiable. The receiving apparatus that is used with this pointing device comprises a light detector for detecting one or more of the plurality of light beams emitted by the pointing device. It determines which of the plurality of individually identifiable light beams are detected. Based thereon the orientation of the pointing device with respect to a target surface may be determined.
