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.
