Abstract
A computer input device, such as a mouse, has a surface movement sensor in communication with a processing circuit for providing to the processing circuit first signals indicative of sensed movement of the computer input device upon a surface, and one or more touchless sensor subsystems in communication with the processing circuit for providing to the processing circuit second signals indicative of sensed surface movements relative to the computer input device. A transmission circuit under control of the processing circuit issues transmissions to a computer representative of the first and second signals.
