Method and system for controlling a display device
First Claim
1. A method for controlling a display device comprising:
- registering a start position, wherein a first location and a first orientation of a remote controller are defined relative to said display device;
detecting movement of said remote controller and responsive thereto determining a second location and a second orientation of said remote controller;
determining a point on a front plane of said display device wherein a line extending from a front edge of said remote controller along a longitudinal axis of said remoter controller intersects said front plane; and
sending a message for causing a cursor displayed upon said display device to be moved to said point.

Abstract
Embodiments of the present invention are directed to a method and system for controlling a display device. In one embodiment, a start position is registered which defines the first position and orientation of a remote controller relative to the position of the display device. When movement of the remote controller is detected, a second position and orientation of the remote controller is determined. A point on the display device is determined where a mathematical line extending from the front edge of the remote controller along its longitudinal axis intersects the front plane of the display device. Finally, a message is sent for causing a cursor displayed on the display device to be moved to the point where the mathematical line intersects the front plane of the display device.

8. A remote controller for a display device comprising:
-
a motion detecting mechanism coupled to a bus;
a memory coupled to said bus;
a wireless communications device coupled to said bus; and
a processor coupled to said bus and for performing;
a) determining a current location and a current orientation of said remote controller in response to a movement of said remote controller relative to a known start position;
b) deriving a point on a display device, wherein a mathematical line extending from a front edge of said remote controller along a longitudinal axis of said remote controller intersects a front plane of said display device; and
c) initiating a message via said wireless communications device for causing said display device to display a cursor at said point on said display device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
