Abstract
A mouse device and method for calibrating sensitivity thereof are provided. The method for calibrating sensitivity includes the following steps. First, sampling information is obtained under a test mode. A calibration factor is obtained according to the sampling information and a preset value. The calibration factor can be obtained by dividing the preset value by the resolution. Under a normal mode, an actual count detected by the mouse device is calibrated according to the calibration factor. Whenever the mouse device is moved on the operating surface for a distance, the actual count detected by the mouse device can be calibrated to obtain a calibrated count. The calibrated count can be calculated by multiplying the actual count by the calibration factor.
