ABSTRACT:
A method of moving the cursor is used in a computer system having a processor operatively coupled to a cursor control device having a light source and an image sensor for optically tracking motion of the cursor control device. The method is executed to move the cursor according to an enhanced tracking value generated based on a measured tracking value, a projected tracking value, and a tracking confidence value based on an illumination value representative of an intensity of light sensed by the sensor.
