Abstract:
A pointing device comprising:a return member being resiliently supported on a substrate surface having an electrically conductive material, the return member having an electrically conductive surface which is spaced from the substrate surface in a first position; anda controller coupled to the return member for moving the return member between the first position and a second position where the electrically conductive surface makes contact with the substrate surface at a contact location, the controller having a disk-like shape with a convex control surface on which to place one or more human digits for manipulating the controller to move the return member between the first position and the second position and to rock the electrically conductive surface on the substrate surface to change the contact location, the convex control surface facing away from the substrate surface, the electrically conductive surface varying in shape during movement on the substrate surface.
