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.
