ABSTRACT:
The present invention is a computer input module comprising: a base; a housing, attached to the base; and at least one set of light (infrared or laser) emitter and detector devices. The input module is adapted so as to generate output signals to a host computer based on the interruption of a light beam or beams between said adjustable emitter and detector devices. The preferred embodiment is a computer mouse wherein light switches, rather than the more typical buttons, are used to generate output signals from a computer mouse to its host computer (an “IR Mouse”). Another embodiment is a Wristband Mouse wherein a wristband replaces the base and housing.
