In general, existing products wear wearable debugging devices with inertial sensors on the wrist to measure the number of movements.However, the disadvantage of the existing products is that it is difficult to measure the number of movements of the wrist in a fixed movement, and it can not be determined according to the user's action characteristics.The purpose of this study is to improve the same existing characteristics as the above-mentioned. An inertial sensor is attached to a cotton hairband, and the number of movements can also be measured when the wrist is fixed.In addition, the user's action characteristics are input before the exercise, and the number of movements can be measured.In order to achieve the above purpose, this paper consists of the following two wrists and three devices worn on the head.first.The wristband 1 is a kind of strap that holds divas on the wrist and an inertial sensor that senses the movement of the user,Moreover, the data obtained by inertial sensor is transmitted to the Bluetooth output device and perceived data on the personal intelligent device through the display screen, which is composed of visual display device,This divas can be fixed to the wrist.Wrist strap 2 and wrist strap 1 have the same composition, but do not contain display screen, only with inertial sensor and output device, only perform measurement function.The headband is a form of belt attached to Dubai's head with inertial sensors and conveyors.According to the results of this study, not only the movement of wrist movement, but also push-up, push-up and other wrist fixed state movement, can also determine the number of exercise.In addition, it is not limited to the data of specific actions recorded in advance, but also can measure the number of movements of users' immediate actions.일반적으로, 기존 제품은 손목에 관성 센서를 포함한 측정 장비가 부착된 웨어러블 디바이스를 착용하여 운동 횟수를 측정한다. 그러나 기존 제품은 손목이 고정된 운동에 있어서 운동 횟수를 측정하기에 어려움이 있고, 원래 입력되어 있던 데이터를 바탕으로 운동 횟수를 판단하여 사용자의 행동 특성을 기준으로 한 측정이 불가능하다는 단점이
