END POINT DETECTION METHOD, MOUSE DEVICE APPLYING THE END POINT DETECTION METHOD AND OPERATING METHOD USING THE MOUSE DEVICE

摘要

End point detection method, a mouse device applying the same and an operating method for preventing complexity are provided to integrate a coordinates conversion function of 3D mouse cursor and a button input function. Noise of acceleration signal outputted from an accelerometer(110) arranged in a pen type mouse device is removed. The piecewise standard deviation toward the k number sample A(k) of the acceleration signal is obtained. In the constant section standard deviation, the local minimum is obtained. The local maximum value between adjacent two locality lowest prices is obtained. The local maximum value is compared with the threshold value.
