Multi-mode input control unit with infrared and laser capability
A multi-mode remote control unit that has both infrared command and laser pointer capability. In some examples, the multi-mode remote control unit together with one or both of a television receiver and a television may implement simulated touch gestures that typically require a touch sensitive screen. The multi-mode remote control unit in such an implementation advantageously may not include logic to implement simulated multi-touch gestures. Rather, one or both of the television receiver and the television may include logic to implement simulated touch gestures.
