Abstract: Provided herein are an auxiliary device and a navigation system using the auxiliary device. The auxiliary device is configured to integrate with a pen mouse. When the pen mouse is tightly combined with the auxiliary device, the auxiliary device determines to use a first cursor displacement information data provided by the pen mouse and/or a second cursor displacement information data provided by the auxiliary device as a control signal for controlling a cursor corresponding to an electronic device according to an operation mode selected by the user.

Abstract: An optical detecting device includes a multi-axis instruction outputting mechanism and an optical detecting module, and shift of the multi-axis instruction outputting mechanism is determined accordingly. An actuating component of the multi-axis instruction outputting mechanism is moved in reciprocation at a first operating direction to output an instruction. The optical detecting module is disposed by the actuating component. An interval between the optical detecting module and the actuating component is varied according to a relative movement between the optical detecting module and the actuating component at a second operating direction, and the actuating component can be shifted between different gears. The optical detecting module determines the interval and related gearshift according to variation of a reflecting signal actuated by the actuating component, and utilizes the reflecting signal to acquire a movement of a feature point on the actuating component along the first operating direction to interpret the instruction.
