The method specifically includes:

S110. Determine the motion track of the user wearing the wearable device by using the somatosensory detection technology.

A wearable device refers to a portable device that is directly worn on the body or integrated into the user's clothes or accessories, such as a smart watch or a smart bracelet, etc., which generally have the functions of playing music, detecting motion and detecting physiological indicators. Features. Somatosensory technology refers to the fact that users can directly use body movements to interact with surrounding devices or environments without using any complicated control equipment; somatosensory detection technology refers to the technology of sensing and recognizing the user's human body movements, for example, through Motion sensor detects. The user's motion trajectory refers to the motion trajectory of the part where the user wears the wearable device, which can be detected by the motion sensor. Specifically, if the user wears the wearable device on the left wrist, the wrist swing trajectory of the left arm can be detected; the user can also simultaneously Wearing multiple wearable devices simultaneously detects the movement trajectories of different body parts of the user.

In this embodiment, the user can directly control the playback of music through the somatosensory action, which is different from the user's daily actions. For example, the somatosensory action can be shaking the arm three times in a row or a specific dance start action, etc. The user can choose to wear the device One of the recommended reference actions, you can also customize the settings.

If the actual time of the user's action track is faster than the standard time of the standard action track, then increase the playing speed of the music rhythm.

The actual time of the user's action track is the time when the user completes any action, and the standard time of the standard action track is the time when the action is completed in the standard action track in the wearable device. Compare the two times to judge the speed of the user's action , especially to compare and judge the trajectory node time of the action. Specifically, for action A, in the standard action track time axis, the time to complete action A is T1, and in the user action track time axis, the time to complete action A is T2. If T2 is greater than T1, it means that the user action track is slower than the standard action track. Action track, which controls the playback speed of slowing down the music rhythm; if T2 is less than T1, it means that the user's action track is block from the standard action track, and controls the playback speed of the music rhythm; if T2 is equal to or approximately equal to T1, it means that the user's action track Consistent or approximately consistent with the standard action track, maintaining the playback speed of the music rhythm. During the music playing process, it can detect and compare the user's motion trajectory in real time to control the playback speed of the music rhythm in real time.

In this embodiment, the playing speed of the music rhythm can have the following levels: beginner, slow down, standard and speed up. During music playing, if it is detected that the user's action track is slower or faster than the standard action track, the playback speed level of the music rhythm is controlled to enter the corresponding next or previous level. Users can also choose the level of playback speed before the music is played.

In this embodiment, by comparing the user's action track with the standard action track, and controlling the playback speed of the music rhythm in real time according to the comparison result, the music rhythm can be adapted to the user's action.
