ABSTRACT:
A pressure-actuated pointing device (PAPD), especially adapted for application in a personal, laptop, or notebook computer, is finger-activated and is used to control the displacement of a cursor on a graphics screen. The PAPD includes at least one rigid finger pad rigidly mounted to and supported by a flexible stem. The stem, in turn, is rigidly mounted to a base plate with the finger pad positioned flush with a forward-facing surface of a computer enclosure. A system operator applies pressure to the finger pad in order to displace the cursor on the graphics screen. The magnitude of the applied positive pressure gradient and point of pressure application on the finger pad determine the magnitude and direction of the cursor's displacement on the graphics screen.
