ABSTRACT:
The present invention includes a pointing device having a first surface on which a puck field of motion is defined, a moveable puck, and a position detector. The moveable puck is confined to move on the first surface within the puck field of motion. The position detector periodically determines a position of the puck in the puck field of motion and an angle of rotation of the puck about an axis perpendicular to the first surface. In one embodiment, the puck includes a puck electrode on a second surface on the puck that is parallel to the first surface. The first surface includes first, second, and third electrodes that are parallel to the puck electrode, the puck electrode overlying a portion of each of the first, second, and third electrodes.
