For example, as illustrated in (b) of FIG. 4, the reference data A may mean position information of each of the coronal axis, sagittal axis, and vertical axis of the exercise image. The movement angle value (B) is an angle of inclination of the joint of the portion where the sensor 100 is worn on the basis of the coronal axis of the exercise image, and an angle of inclination of the joint of the portion of the portion on which the sensor 100 is worn on the basis of the sagittal axis of the exercise image. , And may refer to an angle at which the joint of the portion where the sensor 100 is worn is inclined based on the vertical axis of the exercise image.

The application 210 may generate the exerciser's movement data C using the reference data A and the exercise angle value B (S160). For example, the motion data C may mean data in which the reference data is moved by the size of the exercise angle value with respect to the reference data.

The application 210 may display movement information including the reference data A, the movement data C, and the exercise angle value B (S170). Therefore, the exerciser can grasp his movement in degrees in real time.

According to an embodiment, each of the reference data A and the movement data C may be displayed so as to be connected in an ellipse shape, and the movement data C is the magnitude of the movement angle value B around the reference data A. FIG. Can be displayed by rotating clockwise or counterclockwise.

Therefore, it is possible to provide the exerciser with feedback on the wrong movement and to provide a guide for performing the exercise in the correct posture. In particular, each of the reference data (A) and the movement data (C) is displayed in an ellipse shape so that the athlete can quickly identify his or her wrong movement and monitor in real time which direction the wrong movement occurred in which direction. have.

Referring back to FIG. 3, the application 210 may compare the exercise angle value and the reference angle value (S180). As a result of the comparison, if the exercise angle value coincides with the reference angle value (YES in S180), the application 210 increases the count for the exercise step of the exerciser (S190), and the exercise angle value is equal to the reference angle value. If it does not match, it is possible to reduce the count for the exercise step of the exerciser (S200).

According to an embodiment, the application 210 increases the count for the exercise step of the exerciser if the exercise angle value is within a predetermined range (S190), and if the exercise angle value is repeatedly out of the predetermined range, The count for the exercise step may be reduced (S200).

If the exercise angle value does not match the reference angle value, the application 210 may determine an exerciser's exercise state as an incorrect movement. According to an embodiment, the application 210 may determine that the exercise state of the exerciser is a wrong movement when the exercise angle value repeatedly deviates from a certain range. For example, if it is repeatedly detected that the movement of the pelvis is more than 10 ° while performing the exercise for strengthening the core and hip muscles, the exercise state of the exerciser may be determined to be a wrong movement.

The application 210 may display movement information including reference data (A), movement data (C), and movement angle value (B) while the exerciser performs an exercise with a wrong movement, thereby angling his movement. Not only does it provide real-time insights, but it also provides feedback to the athlete about whether they are exercising in the correct posture.

According to an embodiment, the application 210 may display a message (eg, “the pelvic movement is more than 10 degrees forward” in which direction the wrong movement occurred in which direction during or after the exerciser performed the movement with the wrong movement). Has occurred. ”). Therefore, the athlete may be provided with a guide to perform the exercise in the correct posture.

The application 210 may transmit exercise information including the movement data, the exercise angle value, the exercise step, and the exercise state to the server 300 (S210). The server 300 may present an exercise in which an incorrect movement appears to the exerciser or encourage the exercise based on the exercise information (S220).

For example, the server 300 may present an exercise in which an incorrect movement appears by sending an alarm to perform an exercise of a recently performed exercise step to an exerciser who repeatedly shows an incorrect movement (S220).

In addition, the server 300 may encourage the exercise by sending an alarm to perform the exercise if the exerciser does not perform the exercise for more than a week (S220).

In addition, the server 300 may determine the next exercise step based on the exercise information.
