Patent ID: 8462011

Claim:
A remote controller comprising: a first movement sensor operable to sense a first movement parameter of the remote controller, the first movement sensor outputting a first signal if the first movement sensor senses the first movement parameter of the remote controller, a second movement sensor operable to sense a second movement parameter of the remote controller, a control unit operable to control the second movement sensor to be deactivated so that the second movement sensor is in a power consumption saving mode, and to output a second signal to re-activate the second movement sensor if the control unit receives the first signal output from the first movement sensor while the second movement sensor is deactivated, and a transmission unit which transmits data regarding at least one of the sensed first movement parameter and the sensed second movement parameter of the remote controller to the image display apparatus to control a movement of a pointer displayed on an image display apparatus that is discrete from the remote controller.
