Abstract
A fingerpoint mouse includes an elastic finger pad having a recess formed therein. The recess is configured to receive a finger such as a user's index finger. A photo-diode attaches to the underside of the recess and photo-voltaic sensing cells form an array opposite the photo-diode beneath the recess. The user applies pressure to the fingerpad and thereby causes the diode to point in a direction opposite the direction of the applied pressure. The diode transmits light which impinges on one or more of the photo-voltaic sensing cells. The photo-voltaic cells generate voltage signals indicative of the direction of the pressure applied by the user on the fingerpad. The voltage signals produced by the photo-voltaic cells are decoded and converted to conventional mouse data. The mouse data is used to position a cursor on a graphics screen so that the user controls the movement of the cursor by applying pressure on the fingerpad in the direction of the desired cursor motion.
