A mouse encoding device that includes an operating interface for the user to operate on and a sensing device for sensing user input through the operating interface in order to modulate light pulses and generate encoded electrical signals. Through the rotation of a wheel in the mouse device, a mechanically linked photo-grid wheel is driven to generate a series of encoded signals. Furthermore, the wheel can move slightly in the vertical direction so that an activating switch can be turned on or off to produce yet another signal. Therefore, the movement of a mouse by a user is fully tracked.
