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.
Claims24
A self-powered computer-pointing device comprising:
- a housing;
- a roller ball accommodated within said housing, at least a portion of said roller ball being exposed through an opening in said housing to allow said roller ball to contact a surface on which said computer-pointing device rests, movement of said computer-pointing device across said surface imparting rotation of said roller ball;
- a sensing mechanism sensing movement of said roller ball and generating x-y movement signals corresponding to movement of said computer-pointing device across said surface, said sensing mechanism conveying said x-y movement signals to a host computer;
- and
- a power generating mechanism coupled to said roller ball, said power generating mechanism converting rotational movement of said roller ball into electrical energy that is used as power by said computer-pointing device.
