14. A hand-held remote control for remotely controlling a system with at least one video display having at least one marker associated therewith, the remote control comprising:
-
at least one image sensor; at least one emitter; and a processor in communication with the at least one image sensor and the at least one emitter, the processor processing an image of the at least one marker formed on the at least one image sensor to determine position of a pointer relative to the image of the at least one marker and generating a signal to wirelessly transmit a command to control the video display based on at least the determined position of the pointer. - View Dependent Claims (15, 16, 17, 18, 19, 20)
