Abstract
A mouse comprises a housing for sliding movement on a nonspecific work surface, and a stylus depending from the housing and contacting the work surface. The stylus bends and vibrates during movement, and the direction and distance of movement are derived from such bending and vibration. Strain gauges, mounted directly to the stylus or to a diaphragm mounting the stylus, are used to ascertain bending and vibration. Photocell means are also disclosed to ascertain bending a vibration of the stylus.
