Abstract: A computer input device includes a touch pad module comprising a flexible, rectangular, optically transmissive touch pad and a touch pad controller electrically interconnecting the touch pad and a microprocessor; a flexible, rectangular characters printing membrane disposed under the touch pad; and an EL module comprising at least one flexible, rectangular EL panel disposed under the characters printing membrane, and a programmable driver electrically interconnected the microprocessor and the at least one EL panel, the programmable driver being adapted to program to sequentially activate the at least one EL panel for controlling brightness, color, and overlap of a plurality of light emitting areas of the computer input device.

Abstract: A key shaped pointing device adapted to mounted on a keyboard of a notebook computer, a keypad of a mobile phone, or a keyboard of a PC includes a substrate including two opposite top latches; a circuit board releasably secured to the substrate; a chip fixedly mounted on the substrate and including a light source, a photosensor, and a processor; and a casing including a transparent top window and opposite openings releasably secured to the latches. The finger as a reflection member is adapted to contact the window for creating a first optical path from the light source to the photosensor via the finger. A movement of the finger is adapted to create a second optical path. The processor is adapted to calculate a direction and a distance corresponding to the movement by comparing the second optical path with the first optical path for generating a cursor control output.
