Abstract
A system and method is provided for selecting a light source in a pointing device such as a mouse. The selection of the light source may be based on attributes of a received image, which are in turn based on reflected light received at the pointing device from the tracking surface. Because the attributes of the receive image are related to characteristics of the tracking surface over which the pointing device is moved, an illumination source appropriate for a particular surface type can be chosen.
