a second IMU module for sensing information on movement generated by a user's contact; and an LED module for displaying information received from the application.
In the application, as the user maximally relaxes the muscle of the part to which the electromyography part is attached, the first EMG setting information sensed by the electromyography part and the user contract the muscle of the part to which the electromyography part is attached to the maximum. Accordingly, an initial EMG setting step of receiving the second EMG setting information sensed by the EMG measuring unit and setting the initial EMG information of the user;
