Capacitive mouse

An input device configured to generate a first output in response to input device motion, the input device comprising:

• an enclosure, the enclosure including an external surface and a back surface opposite the external surface;
• a capacitive touch sensor mounted to the back surface;
• and
• a processor, the processor in electrically coupled with the capacitive touch sensor, the processor configured to generate a second output in response to object motion along the capacitive touch sensor.

A computer mouse configured to generate a first output for cursor control in response to computer mouse motion, the computer mouse comprising:

• an enclosure, the enclosure including a touch surface and a back surface opposite the touch surface;
• a circuit substrate mounted to the back surface;
• a plurality of conductive plates mounted to the circuit substrate, the plurality of conductive plates configured to capacitively detect object motion proximate the touch surface;
• a plurality of conductors on the circuit substrate, the plurality of conductors electrically coupled to the plurality of conductive plates;
• a processor, the processor electrically coupled to the plurality of conductive plates through the plurality of conductors, the processor configured to generate a second output for scrolling in response to said object motion proximate the touch surface.

A computer mouse configured to generate a first output for cursor control in response to computer mouse motion, the computer mouse comprising:
