Abstract: A computer input device includes a housing, a move tracking module, and a light pervious plate. The move tracking module is disposed in the housing, and emits a sensing light. The light pervious plate is movably disposed between the housing and the move tracking module, and may be moved between a first position and a second position relatively to the move tracking module. In this manner, the sensing light selectively penetrates the light pervious plate and is emits out of the housing, or is directly emits out of the housing, so that the computer input device correspondingly executes a touch mode or a mouse mode.

Abstract: An illuminating computer input device includes a base, a housing and a light source mounted inside the housing, wherein the housing is transparent or translucent. An covering layer is applied on an outer surface or an inner surface of the housing. A patterned-window is further formed in the covering layer by removing a portion of the covering layer from the housing. By such arrangement, light generated by the light source is able to transmit out of the housing via the patterned-window so as to create an illuminating effect.
