Abstract: A pen mouse includes a housing, a rotatable actuator, an optical sensor and a processor. The rotatable actuator is movably disposed inside the housing along a structurally longitudinal direction and a structurally horizontal direction of the housing. The optical sensor is adapted to detect surface reflection of the rotatable actuator. The processor is electrically connected with the optical sensor and adapted to compute a rotating direction, a rotating angle and depth variation of the rotatable actuator via analysis of the surface reflection.

Abstract: A navigation device with distance detecting function can utilize a distance detecting mechanism to detect a distance relative to a working surface. The distance detecting mechanism includes a base, a connecting component, a feature unit and a detection unit. The connecting component partly protrudes from the base. The connecting component optionally contacts against or is spaced from the working surface to generate a distance variation relative to the base along an axial direction. The feature unit is disposed on the connecting component. The detection unit is connected to the base. The detection unit can detect parameter difference of the feature unit according to the distance variation of the connecting component relative to the base, so as to determine the distance between the working surface and a bottom of the base via the parameter difference.
