Abstract
A touchpad jogger for emulating operator contact with a touchpad surface has a ball rotatably mounted at the end of a spring arm cantilever mounted to one end of an axle. A knob is fixedly mounted to the other end of the axle so that when the knob is rotated the ball is caused to roll across the touchpad surface to emulate operator contact. A plate through which the axle extends provides for attaching the touchpad jogger to a housing containing the touchpad surface.
