ABSTRACT:
An optical reflective mouse or other pointing device for computers which provide an optical signal. The mouse modifies, e.g., interrupts, the optical signal from the computer as a function of the mouse movement or operation of one or more control buttons.
The mouse reflects or retroreflects the modified optical signal to the computer as a computer control signal. The mouse employs retroreflectors, diffraction gratings, prisms, mirrors and other optical elements in combination with a mouse ball operator to complete the mouse. No electronics, radiation sources or batteries or any cable connection to the computer is required.
