In order to timely move the neck so as to reduce the occurrence probability of cervical spondylosis, a user can move the neck according to the guidance in the video by watching related videos, and relax the neck. Illustratively, fig. 3 shows a schematic diagram of a prior art neck movement process. Referring to fig. 3, when a user views a guiding video through a handheld electronic device, the user needs to pay attention to a display screen, so that the movement range of the neck of the user is limited, and a better neck relaxing effect cannot be achieved; on the other hand, in the process of moving the neck, the user often hopes to achieve the purpose of relaxing both the spirit and the body, and if the user needs to pay attention to the guiding video appearing in the display screen at any time, the user needs to pay attention to the guiding video, so that the spirit cannot be fully relaxed, and the use experience of the user is further reduced. Therefore, the prior art has the defects of high operation difficulty and poor user experience when stretching the neck.

In this embodiment, in order to enable guidance of the neck activity, the electronic device may simulate to obtain one simulated sound source through two speakers configured. Because of the binaural effect, the sound source position perceived by the user can be controlled by controlling the loudness and frequency of the audio at the two sides of the ears, filtering the directional sound and other operations, and in this case, the electronic device can control the simulated sound source to move around the preset sound track through the principle of the binaural effect.

In one possible implementation manner, the electronic device may respond to a neck relaxing instruction initiated by a user, and perform control to move the simulated sound source on a preset sound surrounding track, so as to prompt the user to move the neck according to the sound surrounding track, that is, initiate a neck relaxing procedure. Illustratively, fig. 6 shows a schematic diagram of initiating a neck relaxing instruction according to an embodiment of the present application. Referring to fig. 6 (a), the electronic device is a smart phone, in which an application 61 for "sports health" is installed, if it is detected that a user clicks the application 61, an operation interface for sports health may be started, as shown in fig. 6 (b), in the operation interface for sports health, a plurality of different functional controls are included, including a functional control 62 for neck relaxation, and if it is detected that the user clicks the functional control 62, it is identified that the user initiates a neck relaxation instruction, and the operation of S501 is performed. Preferably, in order to facilitate the user to select a suitable speaker to perform neck relaxation guiding, after detecting that the user clicks the function control 62, the smart phone may generate a selection interface of an audio device, where the selection interface includes a plurality of selectable audio playing modes, including a local playing mode and an external device playing mode, where when playing the external device, the external device may be displayed through a corresponding device identifier, as shown in (c) in fig. 6, and the selection interface includes a plurality of selectable options respectively: local play 63, freebuds play 64 (i.e. play through wireless bluetooth headset), and outgoing horn play 65, and the user can select a suitable audio device to play audio according to the actual situation.

Further, as another embodiment of the present application, the electronic device may include a plurality of different audio files, each of which may guide audio corresponding to a different neck activity. For example, the activity amplitude, the activity duration and the exercise emphasis point corresponding to different audio files may be different, the electronic device may display a plurality of different audio files, and the user may select an appropriate target file to play according to the actual activity situation. Fig. 7 is a schematic diagram illustrating selection of an audio file according to an embodiment of the present application. Referring to fig. 7 (a), after the user determines the audio device to be used, a selection interface for audio files may be entered, where the selection interface includes a plurality of selectable audio files, respectively: light relaxed track 1, deep relaxed track 2, left focused relaxed track 3, and right focused relaxed track 4, the user can select the corresponding track according to the actual situation, for example, in this embodiment, the user can click on the control corresponding to deep relaxed track 2 and play the audio file, as shown in fig. 7 (b).

It should be noted that, in addition to the manner of selecting the playing files by user definition, the user may also play each audio file in turn according to the preset playing order, for example, after detecting that the user selects the corresponding audio device, the electronic device may directly enter the audio playing interface, i.e. as shown in (b) of fig. 7, and skip the selecting interface of the audio file, i.e. skip (a) of fig. 7, where in this case, the audio playing interface includes a track switching control, i.e. a previous control 71, a next control 72 and a track list viewing control 73, and of course, the audio playing interface further includes a switching mode selecting control 74, where multiple switching modes based on list playing, random playing, and single-track cyclic playing may be selected by the user according to the actual situation.

In one possible implementation, an electronic device may be configured with a plurality of different play modes. Among them, the play modes include, but are not limited to: normal audio play mode and neck relaxing play mode.

In the neck relaxing mode, the electronic device may adjust the original data of each sound track based on the above-mentioned sound surrounding tracks, so that the simulated sound source in each sound track moves based on the preset sound surrounding track, generate surrounding movement data, and perform the operation of S501 based on the surrounding movement data.

Further, as another embodiment of the present application, fig. 9 shows a flowchart of an implementation of a method for playing audio according to an embodiment of the present application. Referring to fig. 9, compared with the embodiment shown in fig. 5, the embodiment of the present application further includes the following steps before S501, which are specifically described as follows:

in S901, playing an mth course prompt message based on a preset course prompt list; the initial value of M is 1.

In this embodiment, since the neck activity guiding process is only guided by means of audio, the user may not be able to directly know how to perform the neck activity when in first contact, in this case, the electronic device may output corresponding course prompt information according to the preset course prompt list, so as to prompt the user, so that the user can learn how to perform the neck activity following the simulated sound source in the subsequent process conveniently.

For example, the course prompt information may be "please get close to the simulated sound source during the audio playing process", and "sound increase indicates close to the simulated sound source", and "sound decrease indicates far away from the simulated sound source", etc., and the user may determine the correspondence between the change rule of the audio and the relative position of the simulated sound source according to different course prompt information, so as to follow the neck activity subsequently.

In this embodiment, the course hint list may include a plurality of course hint information. The different course prompt messages comprise corresponding prompt orders which are sequentially arranged in the course prompt list. When the electronic equipment plays the prompt information, the electronic equipment can prompt the prompt information in sequence based on the prompt sequence of each information in the course prompt list.

In one possible implementation manner, the electronic device may record the number of times the user performs the neck activity, and if it is detected that the user initiates the neck relaxing instruction for the first time, the operation of S901 may be performed to perform the teaching process before the activity on the user, and after the teaching process is completed, the operation of S501 is performed to perform the neck activity.

In one possible implementation, the course prompt for the user may be initiated when the user first uses the neck activity, and may be performed again when it is detected that the score corresponding to the neck activity for multiple times is low. Specifically, the evaluation report includes an evaluation score of the neck activity, if the evaluation score in the evaluation report of the user for a plurality of times is smaller than a preset score threshold, the user is not able to follow the simulated sound source to perform the activity according to the preset sound surrounding track, and needs to perform the course prompt again, and then the operation of S901 is performed.

In one possible implementation manner, the electronic device may obtain identity information of the user performing the neck activity at this time, for example, through a biometric identification technology such as face recognition, or judge the number of times the user performs the neck activity according to account information such as an account number of the logged-in user, if the number of times of the activity is detected to be 0, it indicates that the user performs the neck activity for the first time, and at this time, the operation of S901 is performed to perform the activity course prompt.

In S902, the actual motion information of the user based on the mth course prompt information is acquired.

In this embodiment, when the electronic device plays the mth course prompt information, the user may be prompted to perform an activity according to the course prompt, and in this case, the electronic device may obtain actual motion information corresponding to the user based on the mth course prompt. The electronic equipment is provided with a motion sensor, and the motion condition of the head of the user can be acquired through the motion sensor, so that corresponding actual motion information is generated based on the motion condition of the head of the user within a preset effective duration. The actual motion information can comprise the motion trail, the motion direction, the motion speed, the motion acceleration and other related information of the head. The information items collected by different course prompt messages may be different, specifically determined according to the course content, that is, the information items contained in the actual motion information corresponding to the different course prompt messages may be different.

In this embodiment, each course prompt information may be associated with corresponding standard motion information, and the electronic device may calculate a matching condition between the standard motion information and the actual motion information, to determine whether the user performs a specified action according to the course prompt information. If the two match, then executing the operation of S903; otherwise, if the two do not match, the operation of S906 is performed.

In one possible implementation manner, the standard motion information includes a corresponding motion feature value, the electronic device may calculate a difference between the motion feature value and an actual motion value in the actual motion information, and if the difference is smaller than a preset deviation threshold, identify that the two motion feature values are matched; otherwise, if the difference value between the motion characteristic value and the actual motion value is greater than or equal to the deviation threshold value, the actual motion information is identified to be not matched with the standard motion information.

In S903, if the actual motion information matches with the standard motion information associated with the mth course alert information, a preset success alert sound is output, and the value of M is increased.

In this embodiment, when detecting that the actual motion information of the user matches with the standard motion information associated with the longer alert information, the electronic device indicates that the user has performed a corresponding action according to the tutorial alert information, and may output a corresponding success alert sound at this time to notify the user that the user may perform the teaching of the next tutorial through the tutorial, so that the value of M may be increased to report the next tutorial alert information in the tutorial alert list.

In S904, if the value of M is less than or equal to the total number of course prompt messages in the course prompt list, the execution is returned to the preset course prompt list, and the mth course prompt message is played.

In S905, if the value of M is greater than the total number of the course prompt messages, a preset completion prompt tone is output.

In this embodiment, if the value of M is smaller than or equal to the total number of the course prompt messages after the value of M is increased, the operation of broadcasting the next course prompt message is returned to be executed until all the course prompt messages in the course list are broadcasted, that is, the value of M is greater than the total number of the course prompt messages, at this time, a corresponding completing prompt sound may be output to prompt the user that the teaching process has been completed, at this time, a corresponding guiding process of the neck activity may be executed, that is, the operation of S501 is executed.

In S906, if the actual motion information does not match the standard motion information associated with the mth course prompt information, outputting a preset failure prompt tone, and returning to execute the operation of playing the mth course prompt information based on the preset course prompt list.

In this embodiment, when detecting that the actual motion information of the user does not match with the standard motion information associated with the course prompt information, the electronic device indicates that the user does not perform the corresponding motion according to the course prompt information, where the user may have a question about the course content and does not understand the action indicated by the course, a failed prompt may be output to prompt the user that the course fails in teaching, and the course prompt is played again, so that the user listens to the course content again and performs the corresponding action.

Illustratively, FIG. 10 shows a schematic diagram of a tutorial prompt provided by an embodiment of the application. Referring to fig. 10 (a), the simulated sound source is located on the left side of the user, and the tutorial prompt message is "moving head, approaching the simulated sound source". At this time, if the user controls the head to swing left, the user approaches the simulated sound source, at this time, the user can be identified that the actual motion information of the user matches with the standard motion information, and a successful prompt tone is output, as shown in (b) of fig. 10, at this time, the next course prompt message can be played; otherwise, if the user controls the head to swing to the right, the user is far away from the simulated sound source, at this time, it can be identified that the actual motion information of the user does not match the standard motion information, and a failed prompt tone is output, and as shown in (c) of fig. 10, the course prompt information is replayed once, that is, "moving the head, approaching the simulated sound source".

In the embodiment of the application, before the user performs the neck relaxing activity, the corresponding course prompt information is played so that the user can move along with the movement of the simulated sound source in the subsequent neck activity process, thereby greatly improving the success rate of the subsequent neck activity and improving the use efficiency.

In S502, head activity information of the user is collected during movement of the simulated sound source on the sound surrounding track.

In this embodiment, in the process of playing the simulated sound source, the simulated sound source moves on the preset sound surrounding track, and the user controls the head to move correspondingly along with the movement of the simulated sound source, so as to determine whether the head movement condition of the user matches with the preset sound surrounding track, the electronic device may acquire the head movement information of the user. The head activity information includes information about the direction, speed, angle, magnitude, etc. of the head activity.

In one possible implementation, the electronic device may establish a communication connection with a distributed camera module, obtain a user activity video including a user's head through the camera module, and locate a face region (i.e., a head region) of the user by performing face recognition on the user activity video, thereby obtaining coordinates of the head region in each frame of video image, and determine head activity information of the head region.

In one possible implementation, the electronic device is in particular a head mounted device comprising a headset assembly and an inertial sensor; the earphone part comprises loudspeakers at two sides of the ear; the inertial sensor is used for acquiring the head activity information. The headset device can be a wireless earphone, a virtual reality VR eyeshade device, a head massager and the like. Wherein the head-mounted device is provided with earphone parts, and each earphone part comprises a corresponding loudspeaker so as to realize control of the simulated sound source to move along the sound surrounding track; the head mounted device also comprises an inertial sensor (Inertial Measurement Unit, IMU) which can be used to obtain the angular acceleration and linear acceleration of the head mounted device to determine movement information of the head mounted device, and since the head mounted device is worn on the head of the user, the movement information of the head mounted device can be regarded as movement information of the head of the user, and the movement of the head is dependent on the neck, the purpose of the movement of the neck can be achieved.

In the embodiment of the application, the earphone part and the IMU are packaged in the head-mounted equipment, and the neck activity of the user is guided by the head-mounted equipment, so that the guiding efficiency can be improved, the neck activity can be completed without the need of holding the equipment by the user, and the operation difficulty of the neck activity is greatly reduced.

Further, as another embodiment of the present application, fig. 11 shows a flowchart for specifically implementing S502 in a method for playing audio according to another embodiment of the present application, and referring to fig. 11, compared with the embodiment described in fig. 5, S502 in the embodiment of the present application specifically includes the following steps, which are specifically described as follows:

in S5021, controlling the simulated sound source to move to an nth key position point on the sound surrounding track; and N is a positive integer.

In this embodiment, when the analog sound source moves on the sound surrounding track, the analog sound source may be divided into a plurality of key position points, where the number of key position points may be determined according to the adjustment accuracy of the audio, or may be determined according to the length of time that the analog sound source stays at each position on the track. If the number of the divided key position points is larger, the response speed of the subsequent user is higher when the head is controlled to move along the sound track; on the contrary, if the number of the divided key position points is smaller, the response speed of the subsequent user when the head is controlled to move along the sound track is slower.

In one possible implementation manner, the electronic device may be configured with a preset separation distance, and a plurality of different key location points are divided on the sound surrounding track based on the separation distance, that is, a distance value between the different key location points is the preset separation distance. Fig. 12 is a schematic diagram illustrating the division of a sound surround track according to an embodiment of the present application. Referring to fig. 12 (a), the sound surrounding track is a circle, but in other implementations, the sound surrounding track may be curved in any shape. The electronic device may divide a plurality of different key location points on the sound surrounding track according to a preset interval distance, where the distance values between the different key location points are the same.

In one possible implementation manner, the electronic device may identify key location points according to the residence time of the simulated sound source at each location, where the simulated sound source may stay at one or more preset key location points in the process of moving around the track, and the electronic device may identify residence time corresponding to each location point on the track, and if the residence time of any location point is greater than a preset time threshold, identify the location point as a key location point. Illustratively, referring to (B) in fig. 12, the duration of stay of the simulated sound source in the position point a is 1s, while not staying in the position point B (i.e., only the position point B is passed, the corresponding stay duration may be determined according to the moving speed of the simulated sound source, for example, the stay duration of all the position points which are passed but not stay may be set to 0.1 s), while the corresponding duration threshold is 0.5s, it may be determined that the stay duration of the position point a is greater than the duration threshold, while the stay duration of the position point B is less than the duration threshold, i.e., the position point a is a key position point, while the position point B is not a key position point.

In this embodiment, the sound surrounding track may be a plane curve or a three-dimensional curve, which is specifically determined according to the neck activity requirement of the user. Therefore, the plurality of key position points may be in the same plane or in different planes.

In S5022, a head pose of the user when the simulated sound source moves to the nth key position point is acquired.

In this embodiment, in order to facilitate the user to feel the relative position change between the head moving process and the simulated sound source, the electronic device may acquire, in real time, the head pose of the user in the process of simulating the movement of the sound source, where the head pose includes two partial parameters, that is, the position of the head and the pose of the head. Because the relative position relation between the simulated sound source and the simulated sound source is not only related to the position of the head, the difference of the head gestures can also influence the distance between the simulated sound source and the ears, so that the relative position relation between the user judgment and the simulated sound source is influenced, and therefore, the electronic equipment can determine the change condition of the head gestures of the user in the process of moving the simulated sound source to the key position point. The electronic equipment can determine the audio content to be played according to the change condition of the head pose, namely the audio content played by the loudspeaker is changed in real time according to the change of the head pose.

In S5023, determining a target audio of each speaker according to the head pose and the nth key position point; the target audio is used for audio segments in the process that the simulated sound source moves from the Nth key position point to the (n+1) th key position point.

In this embodiment, due to the change of the head pose, the relative position between the ears of the user and the simulated sound source is changed, so that in order to improve the simulation effect, the electronic device can determine the audio to be played by each speaker according to the real-time state of the head pose, so that the user can feel the change of the distance between the electronic device and the simulated sound source. Based on the above, the electronic device may determine the target audio to be played according to the relative positional relationship between the head pose and the key position point, and the relative positional relationship between the head pose and the subsequent key point (i.e., the n+1th key position point). In view of the binaural effect and the doppler effect, the loudness and frequency of the sound received by the user may change during the head movement, so the electronic device may determine the frequency change and the loudness change of the audio segment according to the movement speed and the movement distance of the head pose, so that the audio segment is matched with the state of the head movement, thereby simulating and obtaining the change of the relative position between the user and the simulated sound source, and improving the guiding accuracy.

Further, as another embodiment of the present application, the step S5023 may specifically include the following five steps:

step 1: and determining a first distance value between the head of the user and the Nth key position point according to the initial pose of the user and the Nth key position point when the simulated sound source moves to the Nth key position point.

Step 2: a second distance value between the head pose and the nth key position point is determined.

Step 3: determining a first audio segment according to the first distance value and the second distance value; the first audio segment is for simulating a relative change in position between the user's head and the simulated sound source.

Step 4: determining a second audio segment according to the nth key position point, the (n+1) th key position point and the head pose; the second audio segment is for simulating movement of the simulated audio from the nth key location point to the n+1th key location point.

Step 5: and generating the target audio according to the first audio piece and the second audio piece.

In this embodiment, the process of moving the head of the user following the simulated sound source may be divided into two different phases, wherein the first phase is that the user approaches the simulated sound source, and the second phase is that the simulated sound source moves to the next position key point. Based on the method, the electronic equipment can acquire the corresponding initial pose of the head of the user before following the movement of the simulated sound source. The initial pose can be obtained through an IMU of the electronic device, and can also be determined by shooting a video image of the head of the user. The electronic device may determine a first distance value between the first pose of the user's head and the nth key location point according to the first pose. The first distance value is used for determining the relative position relation between the user head and the simulated sound source before the user head approaches the simulated sound source.

In this embodiment, after the user's head tries to approach the simulated sound source, the head's posture changes from the initial posture to the head posture, at which point the electronic device may again determine a second distance value between the head posture and the nth key position point. The second distance value is used for determining the relative position relationship between the user head and the simulated sound source after the user head approaches the simulated sound source.

In this embodiment, the electronic device may follow up the first distance value and the second distance value, determine a position change amount between the head of the user and the simulated sound source, then determine a loudness change, and determine a speed of movement of the head of the user according to a change time between the initial pose and the head pose, thereby determining a frequency change of the first audio segment, and determine a sound change condition of the simulated sound source received by the user according to the loudness change and the frequency change, thereby determining the first audio segment corresponding to each speaker.

In addition to the change of the relative position relationship between the user head and the simulated sound source caused by the movement of the user head, the change of the relative position relationship is caused when the simulated sound source moves on the sound source movement track, and the movement of the simulated sound source needs to determine a second distance value between the Nth key position point and the head pose and a third distance value between the (n+1) th key position point and the head position, and the loudness change of the second audio segment can be determined based on the difference of the two distance values; similarly, the simulated sound source moves on the sound surrounding track at a preset moving speed, so that the frequency change of the second audio segment can be determined according to the preset moving speed, the sound change condition of the process of moving the simulated sound source to the (n+1) th key position point at the (N) th key position point is determined according to the loudness change and the frequency change, the second audio segment corresponding to each loudspeaker is determined, and the first audio segment and the second audio segment are overlapped, so that the target audio in the process can be obtained.

Illustratively, fig. 13 shows a schematic diagram of audio segment determination provided by an embodiment of the present application. Referring to fig. 13 (a), the user's head rotates from point a to point B to approach point C where the simulated sound source is located, at this time, the distance between the two changes from d1 to d2, and the electronic device may determine the first audio segment corresponding to each speaker according to the change in distance between d1 and d 2. On the other hand, referring to fig. 13 (B), when the simulated sound source can move from the position point C to the position point D, the distance value between the simulated sound source and the user head point B is changed from D2 to D3, and the electronic device can determine the second audio segment corresponding to each speaker according to the change of the distance between D2 and D3. The two audio segments are integrated to obtain the target audio segment.

In the embodiment of the application, the process of audio change is divided into two parts, the audio segments corresponding to each part are respectively determined, and then the two audio segments are overlapped to obtain the target audio, so that the accuracy of generating the target audio can be improved, and the simulation effect is improved.

In S5024, increasing the value of N, if the increased value of N is smaller than the total number of key position points on the sound surrounding track, returning to the operation of collecting the head pose of the user after the simulated sound source moves to the nth key position point.

In S5025, if the value of N after the increase is greater than or equal to the total number, the head activity information is generated based on all the head poses.

In this embodiment, when the simulated sound source does not reach the final key position point, the target audio of each speaker is continuously determined in the above manner until the simulated audio has been moved, so that the head activity information of the user can be generated according to all head poses acquired by the head of the user during the movement of the simulated sound source. The electronic device may associate corresponding acquisition times for each head pose, and determine a pose order of each head pose based on each acquisition time, thereby generating the head activity information.

In the embodiment of the application, the simulated sound source can be changed along with the change of the head pose of the user by acquiring the head poses corresponding to different key position points and determining the target audio of the next stage, so that the authenticity of the simulated sound source is improved, and the accuracy of neck activity guidance is improved.

In S503, a scoring report is generated based on the head activity information and the sound surround track.

In this embodiment, the electronic device may determine a movement track of the user's head when obtaining the head activity information corresponding to the user in the process of simulating the movement of the sound source along the sound surrounding track, so as to determine the activity effect of the user's current neck activity according to the movement amplitude, the movement duration and the similarity with the sound surrounding track corresponding to the movement track, thereby obtaining a corresponding evaluation score, and generating a score report corresponding to the evaluation score based on the evaluation score.

In one possible implementation manner, the electronic device may determine an activity amplitude of the head activity information, determine a corresponding activity amplitude score based on the activity amplitude, then determine a total movement duration of the current sound surrounding track (i.e., a total neck activity duration of the user), determine a corresponding duration score, finally generate a head activity track according to all head poses, calculate a similarity between the head activity track and the sound surrounding track, determine an anastomosis score, calculate a corresponding activity total score according to the activity amplitude score, the duration score and the anastomosis score, and obtain a corresponding score report.

In one possible implementation manner, if the electronic device is a head-mounted device, the score report may be output in a voice broadcast manner, and the user may determine the content of the score report by listening to the audio corresponding to the score report. Optionally, if the head-mounted device is connected to other electronic devices, for example, a smart phone, the head-mounted device may send the corresponding score report to the smart phone, and the display module of the smart phone displays the score report, so that the user may view the content of the score report on the smart phone.

Illustratively, FIG. 14 shows a display schematic of a scoring report provided by an embodiment of the present application. Referring to fig. 14 (a), the electronic device that obtains the head activity information of the user is a head-mounted device, and after generating the score report of the current neck activity of the user, the head-mounted device may send the score report to the smart phone through a bluetooth communication connection. The smart phone is provided with a client program associated with the head-mounted device, and the corresponding scoring report can be displayed by starting the client program, as shown in (b) of fig. 14, and the scoring report can display scoring conditions of different dimensions, such as activity magnitude scores, duration scores and coincidence scores.

Further, as another embodiment of the present application, fig. 15 shows a flowchart for specifically implementing S503 in a method for playing audio according to another embodiment of the present application, and referring to fig. 15, compared with the embodiment described in fig. 5, S503 in the embodiment of the present application specifically includes the following steps, which are specifically described as follows:

in S5031, a head motion trajectory of the user during the movement of the simulated sound source on the sound surrounding trajectory is generated according to a plurality of head poses in the head activity information.

In S5032, a trajectory similarity between the head motion trajectory and the sound surrounding trajectory is calculated.

In S5033, a range of motion of the user is determined from the head motion trajectory.

In S5034, the score report is generated according to the trajectory similarity and the range of motion.

In this embodiment, the electronic device acquires a plurality of head gestures in the process that the user follows the simulated sound source to move, and connects each head gesture in turn based on the sequence of the acquisition of each head gesture, so as to generate a head motion track corresponding to the user. And carrying out similarity calculation on the head motion track and the sound motion track of the simulated sound source to obtain the track similarity.

In one possible implementation, the manner of calculating the track similarity may be: based on the acquisition time, establishing an association relation between each coordinate point on the head motion track and each coordinate point on the sound surrounding track, then calculating distance values between each coordinate point on the head motion track and the corresponding coordinate point on the sound surrounding track, and determining track similarity between the two based on the sum of the distance values corresponding to all the head motion tracks or the average value of the distance values. Wherein, the smaller the sum of the distance values or the average value of the distance values is, the larger the corresponding track similarity is; otherwise, if the sum of the distance values or the average value of the distance values is larger, the corresponding track similarity is smaller.

In one possible implementation manner, the electronic device may perform scaling processing on the head motion track, so as to maximize the contact ratio between the scaled head motion track and the sound surrounding track, and use the corresponding value when the contact ratio between the two tracks is maximized as the track similarity between the two tracks.

In this embodiment, the electronic device determines, in addition to the similarity between the two tracks, the range of motion of the head in the current neck motion process, that is, the motion amplitude. The movement amplitude can be determined according to the distance value between the movement track of the head and the axis of the human body, and also can be determined according to the swinging angle of the head, and the movement amplitude is specifically set according to the actual situation.

In this embodiment, the electronic device may import the track similarity and the activity range into a preset report template, so as to generate a score report corresponding to the neck activity. Optionally, the electronic device is configured with a scoring conversion algorithm, the track similarity and the activity range are imported into the scoring conversion algorithm, an evaluation score corresponding to the neck activity can be calculated and obtained, and the evaluation score is added into the scoring report, so that the user can conveniently determine the effect of the neck activity.

In the embodiment of the application, the head activity track in the current activity process is generated through the head activity information, so that the track similarity between the head activity track and the sound surrounding track is determined, the activity range of the user is determined, the neck activity of the user is evaluated from multiple angles, and the accuracy of an evaluation report can be improved.

Further, as another embodiment of the present application, after S503, it may further include:

in S5035, an actual activity magnitude of the user in a plurality of activity directions is determined according to the activity range.

In S5036, if the actual activity amplitude corresponding to any activity direction is smaller than the preset amplitude threshold, identifying any activity direction as the strengthening activity direction.

In S5037, neck exercise cues are generated based on all of the reinforcement activity directions.

In this embodiment, after generating the score report of the current neck activity, the electronic device may perform related exercise advice according to the activity condition of the user at this time. For example, if the user deflects his head to the left by a significantly smaller amount than his head to the right while following the movement of the simulated sound source, the user may experience an imbalance in the left and right neck movements, which may be caused by lack of exercise of the left neck muscles, in which case the electronic device may alert the user to the exercise. Therefore, after the scoring report of the present neck activity is generated, the electronic device can identify the actual activity amplitude corresponding to each preset activity direction in the activity range, compare the actual activity amplitude with the preset amplitude threshold, and if the actual activity amplitude is greater than the amplitude threshold of the corresponding direction, the fact that no abnormality exists in the activity direction is indicated, and the neck exercise prompt information of the activity direction is not required to be generated; on the contrary, if any actual activity amplitude is a preset amplitude threshold value, it indicates that when the neck of the user moves towards the activity direction, there is an abnormal condition with smaller amplitude, and exercise needs to be enhanced, so that neck exercise prompt information about the activity direction can be generated.

Illustratively, fig. 16 shows a schematic diagram of neck exercise prompt information provided by an embodiment of the present application. Referring to fig. 16, after the electronic device outputs the score report, the neck exercise prompt information may be displayed by means of a pop-up frame, so that a user may be reminded of a targeted exercise, for example, "the left side activity range is small, please strengthen the left muscle of the neck", and the user may exercise targeted.

In the embodiment of the application, when the fact that the user has limited activity in a certain activity direction is identified, the user can be prompted, the readability of the evaluation report is improved, and the user can conveniently and well exercise the neck.

It can be seen from the foregoing that, in the audio playing method provided by the embodiment of the present application, corresponding speakers are configured on two sides of a user's ears, so that a simulated sound source is obtained through simulation based on binaural effects, the purpose of prompting the user to perform neck activity is achieved by controlling the simulated sound source to move on a preset sound surrounding track, in the process of user activity of the neck, that is, in the process of moving the simulated sound source on the sound surrounding track, head activity information of the user is collected, and finally matching is performed according to the head activity information and the sound surrounding track, so that an evaluation score of the user's current neck activity is obtained, and the purpose of screen-free guiding activity is achieved. Compared with the existing multimedia playing technology, the embodiment of the application can simulate the corresponding simulated sound source through the binaural effect, achieves the purpose of guiding the activities of the user by controlling the simulated sound source to perform surrounding movement, does not need the user to stare at the screen at any time, but can move towards the appointed direction and the appointed track according to the relative position relation between the simulated sound source and the user, thereby reducing the operation difficulty of the user, enabling the operation of the neck activity to be more flexible and improving the use experience of the user.
