A Zero-Moving-Parts Mouse Using Strain-Gauge Technology

      This article describes a mouse which requires no moving parts
and no special pad or surface for operation.

                            (Image Omitted)

      Two or more piezoelectric or other solid-state strain gauge
transducers are mounted in the body of this mouse between two plates.
These plates are held separate by flexible elastomer elements.

      The transducers are coupled to the upper and lower plates in
such a way as to provide output when pressure is placed along
horizontal (X and Y) axes.

      When the body of the mouse is moved across a surface, these
piezoelectric elements output a voltage proportional to the vectors
and pressures involved in moving the mouse. This voltage is then
amplified and digitized to provide the mouse vector and velocity
information required by the computer.
