2. Description of Related Art
A mouse device is a general input device of a computer system. Recently, speed, resolution and precision of the laser mouse or the optical mouse are better than the mechanical mouse. Even if the speed, resolution and precision are improved, an optimization process of the computer mouse wastes a lot of time to detect the surface parameters of the mouse pad when the mouse device has not been used on the mouse pad for a long time.
Therefore, how to develop a mouse pad providing calibration parameters of the optimization process or the surface parameters of the mouse pad is the topic of the present disclosure.

When the calibration parameters corresponding to the identification number of the mouse device are stored in the storage module of the mouse pad, the calibration parameters can be transmitted to the mouse device through the communication module. Therefore, the optimization process of the mouse device can be sped up. The mouse pad further stores the surface parameters of the first surface detected at different time points and an optimization parameter interval for monitoring the mouse device or the mouse pad. Therefore, the sensitivity of the mouse device moving on the mouse pad can be detected.
