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: A two-dimensional navigation module of a cursor controller includes a top plate, a first rod, a sliding roller sleeved at the first rod, and a first OTS sensor. The top plate has an elongated groove recessed thereon. The first rod is arranged in the groove. Two opposite ends of the first rod are fastened to the top plate. The sliding roller is movable along the first rod between a first position and a second position, and the sliding roller is spinable along the first rod in a range of 0˜360 degrees. When the sliding roller is moved, a center segment of the first rod keeps touching the sliding roller. The first OTS sensor is arranged under the center segment of the first rod for detecting at least one of a moving distance and a spinning angle of the sliding roller.

Abstract: A pen-typed navigation device includes a housing, a pen tip, a pressure detecting unit, and a navigation module having an optical large depth of field detecting unit and a processing unit. The pen tip is disposed on the housing. The pressure detecting unit is disposed on the pen tip to detect a pressure of the pen tip applied to a working plane. The optical large depth of field detecting unit is disposed by the pen tip and has a specific range about the depth of field, and can detect movement information of the pen tip relative to the working plane while a distance between the pen tip and the working plane is smaller than the foresaid specific range. The processing unit is adapted to acquire navigation information generated by the pen tip according to detection result of the pressure detecting unit and the optical large depth of field detecting unit.

Abstract: An electronic device with waterproof structure includes an assembly and a manipulation member movably disposed on an outer surface of the assembly. The assembly includes a case and an optical detection module. The case defines a waterproof space and has a translucent region. The optical detection module is arranged in the waterproof space. The optical detection module has a lighting unit and a sensor array. Light emitted from the lighting unit enables to travel out of the waterproof space by penetrating through the translucent region. At least part of the manipulation member is corresponding in position to the translucent region. The lighting unit is configured to emit light onto the manipulation member, and the sensor array is configured to receive the light reflected from the manipulation member.
