Zusammenfassung: | A mouse having a shake-elimination function when leaving a working plane is provided. A light sensing unit detects a light emitted by a light emitting unit toward a working plane or a column shaped member, and outputs a detection signal. A microprocessor determines whether the mouse is apart from the working plane according to the detection signal. When it is determined that the mouse is positioned apart from the working plane, the microprocessor clears the displacement amount obtained from the communication interface of the optical displacement sensor, and meanwhile the microprocessor inform the computer that the mouse is apart from the working plane. In such a way, when the user lifts the mouse up from the working plane, the displacement signal outputted from the optical displacement sensor won't cause the cursor shake. |
