Abstract: An input device is equipped with a cursor pointing unit including a mechanical control stick and an optical sensor. The optical sensor is mounted on the mechanical control stick and has a contact surface for sensing object motion thereon. A cursor signal is generated when the mechanical control stick is inclined by an exerted pressure. When the mechanical control stick is not inclined, a position frame of the object on the contact surface is retrieved as a reference frame. A real-time position frame of the object is retrieved when the object remains on the contact surface. A speed of the object is calculated according to the reference frame and the real-time position frame. When the speed does not exceed a threshold, a cursor position move is generated according to the speed; and when the speed exceeds the threshold, a switch signal is generated to initiate a gesture controlling mode.
