[0013] In some embodiments of this disclosure, the number of both the first position and the second position is multiple; mapping the first position to the second position of the playground includes:

[0014] Each of the first positions is mapped to its corresponding second position using a mapping relationship;

[0015] The mapping relationship is related to the parameters of the first track of the playground, the position of the center point, and the rotation angle.

[0016] In some embodiments of this disclosure, before mapping each of the first positions to the corresponding second positions using a mapping relationship, the motion information generation method further includes:

[0018] The center point position and the rotation angle are determined based on at least a portion of the first position;

[0019] The mapping relationship is determined based on the first runway parameters, the center point position, and the rotation angle.

[0021] The average value of multiple first positions where the user moves around the playground is taken as the center point position;

[0022] The axis of the playground is determined based on multiple first positions of the user on the bends and / or straight sections of the playground;

[0023] The angle between the first straight line containing the axis and the second straight line containing the standard direction is taken as the rotation angle.

[0024] In some embodiments of this disclosure, after determining the mapping relationship based on the first runway parameters, the center point position, and the rotation angle, the motion information generation method further includes:

[0025] In response to the user's adjustment operation on the runway parameters, the first runway parameters are adjusted to the second runway parameters;

[0026] The mapping relationship is adjusted based on the second runway parameters.

[0027] In some embodiments of this disclosure, the number of the first locations is multiple; after obtaining the user's first location, the motion information generation method further includes:

[0028] Based on each of the first positions, determine the user's movement distance and number of laps;

[0029] The user's movement speed is determined based on each of the first positions and the user's movement time.

[0030] In some embodiments of this disclosure, after determining the user's movement speed based on the first position and the user's movement time, the motion information generation method further includes:

[0031] Display at least one of the first motion trajectory, the motion distance, the number of motion laps, and the motion speed.

[0033] The acquisition module is configured to acquire the user's first location when the user activates the playground mode;

[0041] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0042] When a user activates the playground mode, their initial location is obtained to determine their position during movement. If the playground mode is confirmed, a movement trajectory needs to be generated within that environment. The initial location is mapped to a second location on the playground. Based on this second location, the user's initial movement trajectory is generated, ensuring its characteristics match those of the playground. By mapping the obtained location to the playground location before generating the user's trajectory, the accuracy of trajectory generation is improved, avoiding errors caused by location acquisition biases. Furthermore, by confirming the playground mode after activation, the system avoids generating erroneous playground-like trajectories in non-playground environments due to user settings errors, thus enhancing the reliability of trajectory generation.

Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims. It should also be understood that the term “and / or” as used in this disclosure refers to and includes any or all possible combinations of one or more of the associated listed items.

[0059] With the development of electronic devices, various exercise modes are now available to accurately generate user exercise information. For example, electronic devices may offer running, rope skipping, and elliptical machine modes. Before exercising, the user selects the desired exercise mode on the electronic device and activates it. During exercise, sensors in the electronic device detect the user's heart rate, location, and other information. Based on this information, the device generates and displays the user's exercise data, allowing them to understand their progress. However, due to certain biases in the detection of the user's position by Global Navigation Satellite System (GNSS) sensors, the motion trajectories generated by electronic devices can be inaccurate.

[0060] To address the aforementioned technical issues, this disclosure provides a method for generating motion information. By mapping the acquired location to the location of the playground in playground mode, the user's motion trajectory is generated. This avoids discrepancies between the generated trajectory and the actual trajectory due to biases in detection by global navigation satellite system sensors, thereby improving the accuracy of motion trajectory generation. Furthermore, by confirming the motion mode after the user activates playground mode, discrepancies between the generated trajectory and the actual trajectory are avoided due to user settings errors, thus improving the reliability of motion trajectory generation.

[0061] This disclosure provides a method for generating motion information, such as... Figure 1 As shown, the method includes:

[0062] S100: When the user activates the playground mode, obtain the user's first location.

[0063] S200. If the movement mode is determined to be playground mode, map the first position to the second position on the playground.

[0064] S300: Generate the user's first motion trajectory based on the second position.

[0065] In this embodiment, when the user activates the playground mode, the user's first location is obtained to determine the user's location during movement. If the movement mode is determined to be playground mode, and the user is moving on the playground, a movement trajectory needs to be generated in the playground environment. The first location is mapped to a second location on the playground. Based on the second location, the user's first movement trajectory is generated, ensuring that the characteristics of the first movement trajectory conform to the characteristics of the playground. By mapping the obtained location to the playground location before generating the user's movement trajectory, the characteristics of the movement trajectory are not affected by location acquisition errors, thereby improving the accuracy of movement trajectory generation. Simultaneously, by determining the movement mode after the user activates playground mode, the generation of a movement trajectory that incorrectly conforms to playground characteristics in non-playground environments due to user settings errors is avoided, thereby improving the reliability of movement trajectory generation.

[0066] For example, in step S100, the user can activate the playground mode by clicking on the sports mode on the electronic device. In the sports mode interface, the user can click on playground mode. In the playground mode interface, the track parameters are set, and the start button is clicked to activate playground mode.

[0067] For example, obtaining the user's first location in step S100 can be obtaining the first location detected by the Global Navigation Satellite System (GNSS) sensors. The first location can be represented by latitude and longitude. In addition to obtaining the first location, the altitude, horizontal accuracy, carrier-to-noise ratio (CN value), number of satellites, etc., detected by the GNSS sensors can also be obtained.

[0068] In one embodiment, such as Figure 2 As shown, determining the exercise mode as playground mode in step S200 can be achieved in the following way:

[0069] S210. Generate the user's second motion trajectory based on the first position.

[0070] S220. If the characteristics of the second motion trajectory match the characteristics of the playground, the motion pattern is determined to be the playground pattern.

[0071] In this embodiment, since users may mistakenly set the exercise mode to "playground mode," it is necessary to determine whether the exercise mode is indeed "playground mode" before generating the exercise trajectory. Because the characteristics of the exercise trajectory when a user is exercising on a playground match those of a playground, a second exercise trajectory is generated based on the user's first position. If the characteristics of the second exercise trajectory match those of a playground, the user is exercising on a playground, and the exercise mode is determined to be "playground mode." By combining the characteristics of the exercise trajectory to determine whether the exercise mode is "playground mode," the exercise mode can match the user's actual exercise, thereby improving the reliability of the exercise trajectory generation.

[0072] For example, in step S210, generating the user's second motion trajectory based on the first position can be achieved by connecting multiple first positions sequentially in chronological order to generate the second motion trajectory.

[0073] For example, the features of the second motion trajectory in step S220 conform to the features of the playground. This can be that the shape of the second motion trajectory is approximately the same as the shape of the historical motion trajectory generated when the playground mode is enabled at a historical moment, or that the shape of the second motion trajectory is approximately the same as the shape of the standard playground after rotation and / or scaling, or that at least a portion of the features of the second motion trajectory are approximately the same as the features of the straight sections and / or curves of the playground.

[0074] In one embodiment, determining the exercise mode as playground mode in step S200 can also be done in the following way:

[0075] Determine the percentage of users who enable the playground mode.

[0076] If the activation ratio is greater than or equal to the preset ratio, the exercise mode is set to playground mode.

[0077] In this embodiment, since user habits can reflect user preferences to some extent, the proportion of time a user activates the playground mode is determined, thus determining the proportion of time a user exercises in playground mode. When the activation proportion is greater than or equal to a preset proportion, the user prefers to exercise on the playground, and the exercise mode is determined to be playground mode. By combining the activation proportion of playground mode to determine whether the exercise mode is playground mode, there is no need to generate an additional exercise trajectory for comparison, thereby reducing the complexity of exercise trajectory generation.

[0078] For example, the preset ratio can range from 50% to 100%. The preset ratio can be 60%, 70%, 80%, etc.

[0079] For example, the motion information generation method further includes:

[0080] If the motion mode is determined to be non-playground mode, a first motion trajectory is generated based on the first position. That is, no mapping of the first position is performed.

[0081] In one embodiment, the mapping of the first position to the second position on the playground in step S200 is determined in the following manner:

[0082] The first position is mapped to the corresponding second position using a mapping relationship.

[0083] The mapping relationship is related to the parameters of the first track of the playground, the position of the center point, and the rotation angle.

[0084] In this embodiment, since the shape of the playground is related to the track parameters, and the location of the playground is related to the center point location and rotation angle, each first position is mapped to its corresponding second position using a mapping relationship related to the first track parameters, the center point location, and the rotation angle. By mapping the first positions using this mapping relationship, the mapped second positions can be located on the playground corresponding to the mapping relationship to avoid offset, thereby improving the accuracy of motion trajectory generation.

[0085] For example, the mapping relationship can be expressed as a formula or as a lookup table. Substituting the first position into the mapping relationship yields the second position.

[0086] For example, if the mapping relationship is already determined at a historical time, the mapping relationship can be directly invoked to map each first position. If the mapping relationship is not determined at a historical time, the mapping relationship can be determined based on each first position. Specifically, if the mapping relationship is not determined at a historical time, a first motion trajectory can be generated based on each first position. After the user completes the first lap, the mapping relationship is determined based on each first position of the first lap, and the generated first motion trajectory is adjusted by backtracking through each first position of the first lap.

[0087] In one embodiment, such as Figure 3 As shown, in step S300, the generation of the user's first motion trajectory based on the second position is determined in the following way:

[0088] S310. Resample the second position to obtain the third position.

[0089] S320, Generate the first motion trajectory at the third position.

[0090] In this embodiment, since the second position is a mapped position and cannot be used directly, it is resampled to obtain a third position. A first motion trajectory is generated using this third position, ensuring that the first motion trajectory matches the actual playground where the user is located. By resampling the second position to generate the first motion trajectory, deviations from the actual playground are avoided, thereby improving the accuracy of the motion trajectory generation.

[0091] For example, resampling the second position in step S310 to obtain the third position can be done by uniformly sampling the second position over time to obtain the third position.

[0092] It is understandable that, in addition to using resampling to obtain the third position, methods such as thinning can also be used to obtain the third position; no limitation is made here.

[0093] In one embodiment, such as Figure 4 As shown, before mapping each first position to its corresponding second position using a mapping relationship in the above steps, the motion information generation method further includes:

[0094] S400: Obtain the first runway parameters set by the user. The first runway parameters include the runway distance and the runway number.

[0095] S410. Determine the center point position and rotation angle based on at least part of the first position.

[0096] S420. Determine the mapping relationship based on the parameters of the first runway, the position of the center point, and the rotation angle.

[0097] In this embodiment, since users need to set track parameters when activating the playground mode, and these parameters are related to the shape of the playground, the first track parameters set by the user are obtained to reflect the shape of the playground. Because the user's first position surrounds the center point position during movement on the playground, and some of these first positions are the endpoints of the major and / or minor axes of the playground, the center point position and rotation angle are determined based on at least some of these first positions to reflect the location of the playground. A mapping relationship is determined based on the first track parameters, the center point position, and the rotation angle to reflect the characteristics of the playground. By determining the mapping relationship using the first track parameters and the first position, and ensuring that the mapping relationship matches the actual characteristics of the playground, the accuracy of the motion trajectory generation is improved.

[0098] For example, before activating the track mode, users need to set the track distance and track number in the first track parameter settings within the track mode interface. The track distance can be a standard distance of 200m or 400m. The track number can be track 1, track 2, track 3, etc. Taking a standard distance of 400m as an example, the distance of one lap under different track numbers is explained below. With a standard distance of 400m, the distance of one lap on track 1 is 400m, on track 2 it is 407m, on track 3 it is 415m, on track 4 it is 422m, and so on. The correspondence between the standard distance, track number, and the distance of one lap can be preset.

[0099] In one embodiment, such as Figure 5 As shown, in step S410, the center point position and rotation angle are determined based on at least a partial first position in the following manner:

[0100] S411. Use the average of the multiple first positions of the user during one lap of the playground as the center point position.

[0101] S412. Determine the axis of the playground based on multiple first positions of the user on the curves and / or straight sections of the playground.

[0102] S413. The angle between the first straight line containing the axis and the second straight line containing the standard direction is taken as the rotation angle.

[0103] In this embodiment, since the first position surrounds the center point position, the average of multiple first positions taken by the user during a full lap of the playground is used as the center point position. Because the curves of the playground contain the endpoints of the major axis and the straight sections contain the endpoints of the minor axis, the axis of the playground is determined based on the user's multiple first positions on the curves and / or straight sections. Since the playground needs to rotate relative to the standard direction, the angle between the first straight line containing the axis and the second straight line containing the standard direction is used as the rotation angle. By processing at least a portion of the first positions to obtain the center point position and rotation angle, which correspond to the actual position of the playground, the accuracy of the motion trajectory generation is improved.

[0104] For example, in step S412, determining the axis of the playground based on the user's multiple first positions on the curves and / or straight sections can be achieved by using the direction of the line connecting two first positions on the major axis, or by using the direction of the line connecting two first positions on the minor axis. Alternatively, the axis can be calculated using a dimensionality reduction algorithm (such as principal component analysis), or by using a trajectory region segmentation method. The trajectory region segmentation method includes, but is not limited to, classification methods and clustering methods. Classification methods include, but are not limited to, K-Nearest Neighbor (KNN) and Support Vector Machine (SVM) methods. Clustering methods include, but are not limited to, Gaussian Mixture Model (GMM) and K-Means methods.

[0105] For example, the standard direction can be north-south, east-west, southeast, northwest, etc.

[0106] In one embodiment, such as Figure 6 As shown, after determining the mapping relationship based on the first runway parameters, center point position, and rotation angle in step S420, the motion information generation method further includes:

[0107] S430, in response to the user's adjustment operation on the runway parameters, adjusts the first runway parameters to the second runway parameters.

[0108] S440. Adjust the mapping relationship according to the parameters of the second runway.

[0109] In this embodiment, since users may switch tracks during exercise on the playground, in response to the user's adjustment of track parameters, the first track parameters are adjusted to the second track parameters. Based on the second track parameters, the mapping relationship is adjusted to reflect the characteristics of the adjusted track. By adjusting the mapping relationship after the user adjusts the track parameters, the generated motion trajectory changes and matches the actual characteristics of the track, thereby improving the accuracy of motion trajectory generation.

[0110] In one embodiment, such as Figure 7 As shown, there are multiple first locations. After obtaining the user's first location in step S100, the motion information generation method further includes:

[0111] S450: Determine the user's movement distance and number of laps based on each first position.

[0112] S460. Determine the user's movement speed based on each first position and the user's movement time.

[0113] In this embodiment, since the movement trajectory cannot intuitively reflect the user's situation, the user's movement distance and number of laps are determined based on each first position. The user's movement speed is determined based on each first position and the user's movement time. The movement distance, number of laps, movement speed, and movement trajectory are used as the user's movement information. By determining the movement distance, number of laps, and movement speed, the user can understand their exercise situation on the playground from multiple perspectives, thereby improving the reliability of the generated movement information.

[0114] For example, in step S450, determining the user's movement distance and number of laps based on each first position can be done by determining a distance based on two adjacent first positions in chronological order. The sum of these distances is then used as the movement distance. The first position obtained initially is taken as the starting position. Every certain period of time, once a first position matching the movement direction (to prevent the user from turning back) coincides with the starting position, the number of laps is incremented by one.

[0115] For example, in step S460, determining the user's movement speed based on each first position and the user's movement time can be done by determining the movement distance based on each first position and using the ratio of the movement distance to the movement time as the movement speed, or by calculating the movement distance based on each first position and the movement time using a preset algorithm. The movement speed can be corrected by incorporating the speed observed by the global navigation satellite system sensors.

[0116] For example, in addition to determining the user's movement distance and number of laps based on each first position, the user's movement distance and number of laps can also be determined based on each second or third position. Similarly, in addition to determining the user's movement speed based on each first position and the user's movement time, the user's movement speed can also be determined based on each second or third position. The method for determining the movement distance, number of laps, and movement speed after replacing the first position with the second or third position remains the same as described above and will not be repeated here.

[0117] In one embodiment, after determining the user's movement speed based on the first position and the user's movement time in step S460, the motion information generation method further includes:

[0118] Display at least one of the following: first motion trajectory, motion distance, number of motion laps, and motion speed.

[0119] In this embodiment, by displaying at least one of the first motion trajectory, motion distance, number of motion laps, and motion speed, the user can intuitively understand the motion information, thereby improving the user experience.

[0120] In one embodiment, after obtaining the user's first location in step S100, the motion information generation method further includes:

[0121] The first position is preprocessed, including at least one of drift point removal, cluster point removal, and trajectory smoothing.

[0122] In this embodiment, because the first position detected by the global navigation satellite system sensor may be inaccurate, or the user may acquire multiple similar first positions during a rest stop, the generated motion trajectory may not match the actual position. To address this, drift point removal is performed on the first position to eliminate inaccurately detected positions. Clustering is then applied to the first position to combine multiple similar positions into a single first position. Finally, trajectory smoothing is performed on the first position to smooth the resulting motion trajectory. By preprocessing the acquired first position, invalid first positions can be eliminated, retaining only valid ones, thereby improving the accuracy of motion information generation.

[0123] For example, the drift point removal process includes a drift point detection process and a drift point removal process. In the drift point detection process, simple rule-based judgment or a signal quality model can be used. In the simple rule-based judgment process, the judgment can be based on factors such as the horizontal accuracy and carrier-to-noise ratio detected by the Global Navigation Satellite System (GNSS) sensors, or it can be based on the distance between multiple adjacent first positions. In the signal quality model process, at least some information from the GNSS sensor detection can be input into the signal quality model to obtain the signal quality, and first positions detected with poor signal quality can be removed. The signal quality model can be a Convolutional Neural Network (CNN) model, a Transformer model, etc. Cluster point processing can be implemented using clustering algorithms, such as the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm. Trajectory smoothing processing can use SG filters, Kalman filters, extended Kalman filters, etc.

[0124] This disclosure provides a method for generating motion information, such as... Figure 8 As shown, the method includes:

[0125] S500: When the user activates the playground mode, it obtains the user's first location at different times.

[0126] S510, Preprocess each first position.

[0127] S520: Generate the user's second motion trajectory based on multiple preprocessed first positions.

[0128] S530. If the characteristics of the second motion trajectory match the characteristics of the playground, the motion mode is determined to be the playground mode.

[0129] S540: Obtain the first runway parameters set by the user.

[0130] S550: The average of the first positions after multiple preprocessing steps taken by the user during a lap around the playground is used as the center point position.

[0131] S560: Determine the axis of the playground based on the first position after multiple preprocessing steps of the playground's curves.

[0132] S570. The angle between the first straight line containing the axis and the second straight line containing the north-south direction is taken as the rotation angle.

[0133] S580. Determine the mapping relationship based on the parameters of the first runway, the position of the center point, and the rotation angle.

[0134] S590. Map each preprocessed first position to its corresponding second position using a mapping relationship.

[0135] S600, resample each second position to obtain multiple third positions.

[0136] S610, Generate the first motion trajectory using each third position.

[0137] S620: Determine the user's movement distance and number of laps based on the first position after each preprocessing step.

[0138] S630. Determine the user's movement speed based on the first position after each preprocessing step and the user's movement time.

[0139] S640 displays the first motion trajectory, motion distance, number of motion laps, and motion speed.

[0140] In this embodiment, when the user activates the playground mode, the user moves on the playground, and the user's first position at different times is obtained. Each first position is preprocessed to remove invalid first positions and retain valid ones. Based on multiple preprocessed first positions, a second movement trajectory of the user is generated to determine the characteristics of the second movement trajectory. If the characteristics of the second movement trajectory match the characteristics of the playground, the user moves on the playground, and the movement mode is determined to be playground mode. The first track parameters set by the user are obtained to determine the shape and size of the track. Since the track revolves around the center point, the average of multiple preprocessed first positions of the user moving one lap on the playground is used as the center point position. Since the line connecting the endpoints of the two curves is the major axis of the playground, the axis of the playground is determined based on the multiple preprocessed first positions of the user on the curves of the playground. The angle between the first straight line containing the axis and the second straight line containing the north-south direction is used as the rotation angle to make the direction of the playground consistent with the actual direction. Since the first track parameters, the center point position, and the rotation angle determine the characteristics of the playground, a mapping relationship is determined based on the first track parameters, the center point position, and the rotation angle. The preprocessed first positions are mapped to their corresponding second positions using a mapping relationship, ensuring the user's location is on the playground. Since the second positions are mapped and cannot be used directly, they are resampled to obtain multiple third positions. A first motion trajectory is generated using these third positions to obtain the user's motion trajectory on the playground. Based on the preprocessed first positions, the user's movement distance and number of laps are determined, resulting in the user's total movement distance and number of laps on the playground. Based on the preprocessed first positions and the user's movement time, the user's movement speed is determined, resulting in the user's movement speed on the playground. The first motion trajectory, movement distance, number of laps, and movement speed are displayed, allowing the user to intuitively understand the movement information. By mapping the acquired positions to the playground locations before generating the user's motion trajectory, the accuracy of motion trajectory generation is improved, avoiding the influence of position acquisition deviations on the trajectory characteristics. Furthermore, since motion information can be processed in real-time over short distances or post-processed, the flexibility of motion information generation is enhanced.
