Motion state detection method and device

The invention provides a motion state detection method. The method comprises the following steps: acquiring motion amplitude information of an arm; in order to obtain the motion amplitude informationof the arm, a user can be required to wear a watch, and configuring a sensor on the watch; filtering the motion amplitude information of the arm to obtain effective motion feature information; and detecting motion state data according to the effective motion characteristic information; filtering processing is performed on the motion amplitude information of the arm, so that abnormal data can be removed, and the accuracy and effectiveness of motion feature information can be ensured. After the motion characteristics are determined to be the effective motion characteristics, the motion state ofthe user is detected, so that more targeted motion data is obtained. Therefore, the motion state of the user is detected in a targeted manner. Therefore, the next operation is facilitated. 本发明提供了一种运动状态检测的方法，方法：获取手臂的运动幅度信息；为了获取
