Claim Text:
1. A cursor control device comprising: a light source for illuminating a sensitive region; a sensor for sensing a motion of an object in the sensitive region; a confidence calculation section for determining a tracking confidence value using illumination information received from the sensor; a projection calculation section for determining a projected tracking value using a historical tracking value; and an enhancement calculation section for determining an enhanced tracking value using the tracking confidence value, the projected tracking value and a measured tracking value, the measured tracking value being representative of the motion sensed by the sensor; wherein when the tracking confidence value is equal to zero, the enhanced tracking value is equal to the projected tracking value; and, wherein when the tracking confidence value is equal to a value between zero and one, the enhanced tracking value is equal to a sum of the measured tracking value and the projected tracking value.
