Abstract
A pointing device having a puck that is confined to move in a field of motion on a surface and that provides pointing and clicking functions analogous to those of a conventional mouse is disclosed. The puck has first and second members that are spaced apart from one another by a resilient spacer when no force is applied between the members. The puck includes a tilt mechanism for allowing the first and second members to assume a tilted configuration with respect to one another in response to a force being applied between the first and second members. A position detector determines the position of the puck in the puck field of motion and a tilt position of the first member with respect to the second member. The determined tilt position is used to emulate two or more switches that are actuated by varying the tilt position.
