Abstract
A joystick includes a casing, a stick body and an optical sensor. The casing has a hole. The stick body is movably disposed on the casing via the hole. The stick body includes a pressing portion, an indication portion and an identification pattern. The indication portion is connected to the pressing portion and inserts into the hole. A sunken structure is formed on a bottom of the indication portion. The identification pattern is disposed on an inner surface of the sunken structure. The optical sensor is disposed inside the casing and faces the sunken structure, and adapted to analyze a movement of the identification pattern to identify a control status of the stick body.
