ABSTRACT:
A self-powered computer-pointing device includes a housing and a roller ball accommodated within the housing. At least a portion of the roller ball is exposed through an opening in the housing to allow the roller ball to contact a surface on which the computer-pointing device rests. Movement of the computer-pointing device across the surface imparts rotation of the roller ball. A sensing mechanism senses movement of the roller ball and generates x-y movement signals corresponding to movement of the computer-pointing device across the surface. The sensing mechanism conveys the x-y movement signals to a host computer. A power generating mechanism is coupled to the roller ball and converts rotational movement of the roller ball into electrical energy that is used as power by the computer-pointing device.
