DEVICE FOR SENSING MOTION AND METHOD FOR SENSING MOTION

摘要

PURPOSE: A motion sensing device and a motion sensing method are provided to vary an ODR(Online Alternative Dispute Resolution) according to a change rate of signals outputted by a sensor, thereby outputting digital data precisely reflecting the movement of a sensing object. CONSTITUTION: A motion sensing device comprises a sensor(110), a change rate determining unit(142), an output data rate control unit(143), and a digital signal output unit(144). The sensor senses motions. The change rate determining unit determines a change rate of the signals output by the sensor. The output data rate control unit controls an output data rate. The digital signal output unit leads a signal value output by the sensor at the controlled output data rate, thereby outputting the same into a digital value.
