Claim:
A remote controllable video display system, comprising: (1) a video display host; (2) a light source for emitting a light signal; (3) a remote controller movable three-dimensionally for generating control information, including: (3a) an optical sensor for sensing the light signal to detect a relative position of the optical sensor to the light source, and generating a first electronic signal representing positional information; (3b) a signal processing and transmitting device for receiving and processing the first electronic signal to transmit a first wireless signal; and (3c) a first button with a predetermined function; and (4) a receiver device coupled to the video display host, the receiver device receiving the first wireless signal and generating a second electronic signal which is inputted to the video display host, wherein when the first button is pressed or released, action information about the status of the first button (pressed or released) is outputted, but (i) the positional information is not outputted or not processed within a predetermined period of time, or (ii) the positional information is not outputted or not processed when the remote controller has an acceleration larger than a predetermined value.
