    Abstract: An image identification method is used to eliminate accumulated error of operation of a joystick. The joystick has an optical sensor adapted to analyze a movement of a plurality of identification dots disposed on a stick body. The image identification method includes receiving a series of detection images, setting a first identification dot of the plurality of identification dots as being a reference identification dot, and setting a second identification dot of the plurality of identification dos as being the reference identification dot and cancelling the first identification dot as being the reference identification dot when the first identification dot is near a border of the detection image. A position change of the reference identification dot in the series of detection images is used for identifying a control status of the joystick.

    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.

    Abstract: A pen mouse is provided for controlling a movement of a cursor displayed on a monitor. The pen mouse includes a pen and an optical detection module assembled in the pen. The optical detection module includes a circuit board, two sensors, and a laser emitter, the latter two of which are assembled onto the circuit board. When the pen mouse is moved along a working surface to implement a mouse control motion, the two sensors receive a detection light emitted from the laser emitter and reflected by the working surface, so as to determine whether the mouse control motion is a pen-tilted motion or a pen-spinning motion, thereby compensating the movement of the cursor.
