[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0017] Figure 1 This is a flowchart illustrating a control method for an earphone charging case according to an embodiment of the present invention. The present invention provides a control method for an earphone charging case, such as... Figure 1 As shown, the method in this embodiment includes the following steps:

[0018] Step S101: Obtain the attitude data of the earphone charging case detected by the attitude detection device.

[0019] Optionally, the attitude detection device is a hardware component or module capable of acquiring, measuring, and outputting attitude information (such as angle, position, orientation, and motion state) of an object (including a human body) in three-dimensional space. In some embodiments, the attitude detection device may include measuring devices such as accelerometers, gyroscopes, and magnetometers. In some embodiments, the attitude detection device may include measuring devices such as structured light / infrared sensors and cameras. In some embodiments, the attitude detection device may include measuring devices such as tilt sensors. These measuring devices are located inside the earphone charging case and can be used to measure attitude data such as acceleration and direction changes, facilitating the acquisition of the earphone charging case's position, motion posture, and motion trajectory, and enabling control of the earphone charging case's display screen to show the corresponding display.

[0020] Step S102: In interactive mode, determine the motion posture of the earphone charging case based on the posture data, and control the display screen of the earphone charging case to display the motion image corresponding to the motion posture; the motion posture includes at least one of tilting posture and shaking posture.

[0021] In this embodiment, the process of controlling the display screen based on posture data includes at least an interactive mode. In the interactive mode, the display screen and the movement posture of the earphone charging case have an interactive paradigm of "posture synchronization mapping". An algorithm is used to establish a matching relationship between the physical posture of the earphone charging case and the display screen. In this embodiment, the movement posture can be at least one of tilting posture and swaying posture, and can also be a flipping, impact, free fall, or other movement postures.

[0022] Optionally, controlling the display screen of the earphone charging case to show motion images corresponding to the motion posture can include: controlling the virtual image on the display screen of the earphone charging case to display motion images corresponding to the motion posture. Specifically, in this embodiment, the earphone charging case can have at least one preset virtual image, which can be a stick figure, cartoon character, animal model, or other fun virtual model. This creates a "posture synchronization mapping" interaction paradigm, establishing a real-time and precise correspondence between the physical posture of the earphone charging case and the skeletal movement of the virtual model through an algorithm. This achieves real-time synchronization between the virtual model and the motion posture (physical posture) of the earphone charging case, creating a "what you see is what you get" intuitive interactive experience. For example, if the user tilts the earphone charging case, the virtual image on the display screen of the earphone charging case can also tilt to the left, maintaining synchronized movement with the real world. The operating logic can be understood without learning, improving the user experience. This embodiment breaks away from the homogeneous competition of the "single charging case" earphone charging case, creating a memorable product through unique interactive and entertainment functions. Optionally, the virtual image in this embodiment can download new characters and skins through a mobile terminal APP, thereby continuously attracting user participation and forming an ecological closed loop.

[0023] In this embodiment of the invention, the earphone charging case integrates a display screen and a posture detection device, which detects the posture data of the earphone charging case. In interactive mode, the movement posture of the earphone charging case (including at least one of tilting and shaking postures) is determined based on the posture data, and the display screen of the earphone charging case is controlled to display the corresponding motion image based on the movement posture. This embodiment maps physical world posture changes and device state transitions into rich visual interactions, enabling the virtual image on the screen to achieve real-time synchronization and contextualized interaction with the physical posture. Users can obtain immersive or personalized visual feedback related to earphone use through the earphone charging case. This embodiment upgrades the traditional charging accessory into a smart earphone charging case that can provide richer visual information and interactive experience, reconstructing the functional value and user experience of the product.

[0024] The above is the core idea of ​​this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] Optionally, the attitude detection device may include a three-axis accelerometer to acquire attitude data of the earphone charging case detected by the attitude detection device. This may include: acquiring three-axis acceleration data of the earphone charging case detected by the three-axis accelerometer; correspondingly, determining the motion attitude of the earphone charging case based on the attitude data may include: determining the pitch angle and roll angle based on the three-axis acceleration data; if the absolute value of the pitch angle and / or roll angle is greater than a first angle, then determining that the motion attitude of the earphone charging case is tilted; and / or determining the composite acceleration vector based on the three-axis acceleration data; if the rate of change of the amplitude of the composite acceleration vector exceeds a first preset rate, then determining that the motion attitude of the earphone charging case is swaying.

[0026] A three-axis accelerometer can detect the acceleration data of the earphone charging case along the X, Y, and Z axes. The X and Y axes are perpendicular to each other and lie in the horizontal plane, while the Z axis is perpendicular to the horizontal plane. The control module of the earphone charging case reads the raw data (three-axis acceleration data) from the three-axis accelerometer and interprets the motion posture using a specific algorithm. Specifically, the control module reads the raw acceleration values ​​along the three axes from the three-axis accelerometer, typically expressed as ax, ay, and az (units are usually gravitational acceleration g or m / s²). Theoretically, when the three-axis accelerometer is stationary and horizontally placed, only the Z-axis experiences 1g of gravity, and the X and Y axis accelerations should be 0. However, there is a zero-point error. At the factory or user trigger, the earphone charging case is kept horizontally stationary, and the readings of each axis at this time are recorded as "zero bias values." The corresponding zero bias value is subtracted from all subsequent readings. The three-axis accelerometer is very sensitive to high-frequency vibrations and instantaneous jitter, but this can introduce errors in the judgment of motion posture. This embodiment can use a first-order low-pass filter to filter out high-frequency noise in order to obtain relatively stable, low-frequency attitude changes.

[0027] After the three-axis acceleration data undergoes the aforementioned zero-bias calibration and low-pass filtering, the tilt angle of the acceleration vector is obtained. Specifically, the calibrated and filtered acceleration vector can be converted into intuitive pitch and roll angles. When the earphone charging case is stationary or moving slowly, the direction of the acceleration vector measured by the three-axis accelerometer is the direction of gravity. By analyzing the projection ratio of the gravity vector on each axis, the angle of the acceleration vector relative to the horizontal plane can be calculated. The pitch angle (θ) is the angle of rotation (forward and backward tilt) around the Y-axis. θ = atan 2 (-ax_filtered, az_filtered); Roll angle (Roll, φ) is the angle of rotation (left and right tilt) around the X-axis. φ = atan 2 (ay_filtered, az_filtered). Where ax_filtered is the filtered X-axis acceleration; az_filtered is the filtered Z-axis acceleration; ay_filtered is the filtered Y-axis acceleration; and atan... 2(y, x) is a two-parameter arctangent function that can correctly handle angles in all quadrants, with calculation results ranging from -180° to +180° (or -π to +π radians), making it more accurate than the single-parameter atan(). In the above formula, the direction of tilt is determined by the sign of the acceleration. In this embodiment, ax is negative when calculating the pitch angle, and to conform to common coordinate system definitions, the pitch angle is positive when the headphone charging case tilts forward. For example, the headphone charging case tilts forward when the pitch angle is positive; it tilts backward when the pitch angle is negative; it tilts to the right when the roll angle is positive; and it tilts to the left when the roll angle is negative.

[0028] In an optional embodiment of the present invention, if the absolute value of the pitch angle or roll angle is greater than a first angle, the movement posture of the earphone charging case is determined to be tilted. For example, the first angle can be 15 degrees. When the absolute value of the pitch angle is greater than 15 degrees, the earphone charging case is determined to be tilted forward or backward; when the absolute value of the roll angle is greater than 15 degrees, the earphone charging case is determined to be tilted left or right. In this embodiment, when the earphone charging case tilts to the left, the virtual image on the screen also tilts to the left; when the earphone charging case tilts to the right, the virtual image on the screen also tilts to the right, maintaining synchronization with the movement in the real world. It should be noted that the tilt angle of the earphone charging case and the tilt angle of the virtual image can be the same or different. If the tilt angle of the earphone charging case and the tilt angle of the virtual image are different, they can be proportionally mapped. For example, if the tilt angle of the earphone charging case is 30 degrees, then the tilt angle of the virtual image is 15 degrees.

[0029] In addition to the tilting posture mentioned above, the headphone charging case can also exhibit a shaking posture. During the shaking posture determination process, the composite acceleration vector sqrt(ax²+ay²+az²) of the three-axis acceleration data ax, ay, and az is obtained. If the rate of change of the amplitude of the composite acceleration vector exceeds a first preset rate, the headphone charging case's motion posture is determined to be shaking. For example, when shaking of the headphone charging case is detected (such as two rapid shakes), a preset specific animation (such as cheering or jumping) is triggered on the virtual avatar.

[0030] Based on the above embodiments, the motion posture includes a do-not-disturb posture. Controlling the display screen of the earphone charging case to display the motion image corresponding to the motion posture can include: when the motion posture of the earphone charging case is a do-not-disturb posture, controlling the earphone charging case and / or earphones to enter a do-not-disturb mode; wherein, in the do-not-disturb mode of the earphone charging case, the display screen of the earphone charging case displays a do-not-disturb message; in the do-not-disturb mode of the earphones, the earphones enter a noise cancellation mode.

[0031] In an optional embodiment of the present invention, the earphones and charging case can also quickly switch between scene modes based on the movement posture. Specifically, by performing a specific action (Do Not Disturb posture) on the earphone charging case, the working mode of the earphone charging case or earphones can be switched with one click. For example, when the movement posture is the Do Not Disturb posture, the earphone charging case can be controlled to display a Do Not Disturb message or the earphones can be controlled to enter noise cancellation mode. For example, the Do Not Disturb posture is flipping the earphone charging case. When the earphone charging case is flipped and placed face down on a table, the display screen of the earphone charging case displays "Do Not Disturb Mode" and the earphones enter noise cancellation mode. Optionally, when the earphone charging case is picked up again and shaken, the display screen of the earphone charging case can switch to display "Transparency Mode" and the earphones can be controlled to exit noise cancellation mode. Optionally, when the absolute value of the pitch angle or roll angle is greater than a set angle value (such as 180 degrees), the movement posture is determined to be flipping. In this embodiment, the virtual model of the earphone charging case and its physical posture can be synchronized in real time, creating a WYSIWYG intuitive interactive experience. This upgrades the traditional charging accessory into a smart earphone charging case that provides richer visual information and interactive experience. It is understood that in other embodiments, the "Do Not Disturb" posture can also be any posture other than rolling; this is not specifically limited here, but merely an example.

[0032] Optionally, the control method for the earphone charging case may further include: in interactive mode, controlling the display screen of the earphone charging case to display a motion image corresponding to the earphone status based on the earphone status; the earphone status includes earphone removal and earphone placement. In interactive mode, in addition to matching the display screen with the corresponding motion posture, the interaction between the earphone charging case and the user can also be realized through the earphone status. For example, when the earphone status is earphone removal, the control module controls the display screen of the earphone charging case to display the text "Goodbye"; when the earphone status is earphone placement, the control module controls the display screen of the charging case to display the text "Welcome Home". This embodiment develops a "contextualized event response" mechanism, which transforms hardware events such as earphone removal / placement into intelligent signals that trigger emotional feedback from the virtual avatar.

[0033] In an optional embodiment of the present invention, the control method for the earphone charging case may further include: controlling the scene mode of the motion display according to the state of the earphone charging case. Specifically, the state of the earphone charging case includes the remaining battery power. When the remaining battery power is lower than a first battery level, the earphone charging case display can show a tired or sleepy virtual image; when the remaining battery power is higher than a second battery level, the virtual image can show an energetic animation. This embodiment establishes an emotional connection between the user and the device through text or virtual image greeting animations and state responses (such as the model showing a tired state when the battery is low), further providing a smart earphone charging case with richer visual information and interactive experience. Furthermore, the control state information is personalized, transforming the monotonous battery power and connection status data into the "energetic state" of the virtual model, making the information acquisition process vivid and interesting.

[0034] In another embodiment of the present invention, in addition to realizing contextualized interaction, entertainment functions can also be realized, specifically, such as... Figure 2 As shown, Figure 2 This is a flowchart illustrating another control method for an earphone charging case provided in an embodiment of the present invention. The present invention provides another control method for an earphone charging case, such as... Figure 2 As shown, the method in this embodiment includes the following steps:

[0035] Step S201: Obtain the attitude data of the earphone charging case detected by the attitude detection device.

[0036] Step S202: In interactive mode, determine the motion posture of the earphone charging case based on the posture data, and control the display screen of the earphone charging case to display the motion image corresponding to the motion posture; the motion posture includes at least one of tilting posture and shaking posture.

[0037] The specific steps of steps S201 to S202 have been described in detail in the above embodiments and will not be repeated here.

[0038] Step S203: In motion-sensing game mode, determine the motion command of the earphone charging case based on posture data and motion-sensing game type; and control the display screen of the earphone charging case to display the game screen corresponding to the motion command according to the motion command; the motion command includes at least one of gesture command and shaking command.

[0039] In this embodiment, in addition to the interactive mode, a motion-sensing game mode is also included. In motion-sensing game mode, independent motion-sensing games can be played through the earphone charging case without the need for a mobile terminal such as a mobile phone, allowing users to enjoy entertainment anytime, anywhere, turning the earphone charging case into a portable game console, perfectly filling fragmented time such as charging and waiting.

[0040] Optionally, determining the motion command of the earphone charging case based on posture data and the type of motion-sensing game may include: if the motion-sensing game is a gesture game and it is determined that there is a gesture operation based on posture data, then the motion command of the earphone charging case is determined to be a gesture command; the gesture command includes at least one of a circle drawing command and a slashing command; and / or, if the motion-sensing game is a dice game and it is determined that there is a shaking operation based on posture data, then the motion command of the earphone charging case is determined to be a shaking command.

[0041] This system aims to transform the earphone charging case into a motion-sensing game controller, with its data processing method serving the gameplay itself. Of course, this embodiment also requires the detection of the earphone charging case's posture data via a posture detection device. Optionally, the posture detection device includes a three-axis accelerometer. Acquiring the posture data of the earphone charging case detected by the posture detection device can include: acquiring the three-axis acceleration data of the earphone charging case detected by the three-axis accelerometer. In this embodiment, the control module can perform targeted processing on the three-axis acceleration data according to the currently running game type. However, when filtering the three-axis acceleration data, the filtering parameters can be improved as needed to retain different motion responses. Unlike the interaction mode, this embodiment no longer calculates a general tilt angle, but directly maps the three-axis acceleration data into discrete or continuous game control commands (motion commands).

[0042] In this embodiment, the motion commands include at least one of gesture commands and shaking commands, and the motion-sensing game types include gesture games and dice games. If the current motion-sensing game is a gesture game, the gesture operation can be determined through three-axis acceleration data. Optionally, the existence of a gesture operation can be determined based on posture data, including: according to the data sequence of three-axis acceleration data within a preset collection time period; if the feature value of the data sequence matches the feature value of a preset gesture operation, then it is determined that a gesture operation exists; the feature value includes at least one of peak value, waveform, and trajectory. Peak value: refers to the local maximum value of the three-axis accelerometer data in the time domain. Waveform: refers to the overall morphological characteristics of the three-axis accelerometer data changing over time, including time-domain attributes such as signal period, amplitude, and rise / fall slope. Trajectory: refers to the path characteristics formed by the continuous changes in posture or position of the earphone charging case when it moves in three-dimensional space, which is obtained by fusion calculation of three-axis accelerometer data.

[0043] This embodiment can collect a continuous data sequence of three-axis acceleration data within a preset collection time period, and then extract feature values ​​from the data sequence. These feature values ​​can be parameters such as peak values, waveforms, and trajectories. The feature values ​​of the data sequence are then matched with the feature values ​​of preset gesture operations pre-stored in the earphone charging case. For example, if the motion trajectory of the data sequence is the same as the trajectory of the gesture operation, it is determined that the current three-axis acceleration data sequence of the earphone charging case matches the preset gesture operation, and the motion command of the earphone charging case is determined to be a gesture command. This controls the display plane to show the game screen after the gesture command is executed. Gesture commands can include circle drawing commands and slicing commands. For example, if the gesture game is a fruit-slicing game, when the motion command is a slicing command, the display screen can show the fruit being sliced. When the current motion-sensing game is a dice game, it is determined whether the motion command of the earphone charging case is a shaking command. If so, the display screen of the earphone charging case displays random numbers. Correspondingly, determining the existence of a shaking operation based on posture data can include: obtaining a composite acceleration vector based on the three-axis acceleration data; and determining the existence of a shaking operation when the amplitude of the composite acceleration vector exceeds a set amplitude threshold.

[0044] In other examples of this embodiment, the motion-sensing game type can also be a balance game, a level game, a jump rope game, or a pedometer game. Specifically, if the motion-sensing game is a balance game, the X-axis and Y-axis acceleration data from the three-axis acceleration data can be directly mapped to the velocity vector (Vx, Vy) of the ball on the display screen; if the motion-sensing game is a level game, the calculated real-time pitch and roll angles are mapped to the simulated bubble or horizontal line position on the headphone charging case's display screen, providing a precise level measurement tool or a challenge game based on this (such as a challenge to place the headphone charging case at a specified angle); if the motion-sensing game is a jump rope game, the periodic acceleration changes of the headphone charging case in the vertical direction (Z-axis) are monitored, and each "jump" action is identified through a peak detection algorithm and accumulated, displaying a virtual jump rope animation and real-time count on the headphone charging case's display screen; if the motion-sensing game is a pedometer game, by analyzing the periodic vibration patterns in the three-axis acceleration data that match the gait characteristics of pedestrians, a gait detection algorithm is used to estimate the number of steps taken, and the step count, estimated distance, and other data can be displayed on the headphone charging case's screen.

[0045] In this embodiment, the control module determines control commands (such as directions, buttons, and gesture codes) that can be recognized by the game logic based on the motion-sensing game type and posture data. The game engine receives the control commands (motion commands) and updates the game state (such as character position, score, and level progress) according to the game rules. Based on the new game state, the engine renders a complete game scene interface, which is independent of the model interaction interface. The control module outputs a complete frame of game screen image data and displays it on the display screen, so the user can see the game progress interface.

[0046] In another embodiment of the invention, in addition to providing contextualized interaction and entertainment functions, a safety monitoring capability is also included, thereby upgrading the traditional charging accessory into a smart terminal integrating emotional interaction, entertainment functions, and safety protection, completely reconstructing the product's functional value and user experience. Specifically, as... Figure 3 As shown, Figure 3 This is a flowchart illustrating another control method for an earphone charging case provided in an embodiment of the present invention. The present invention provides another control method for an earphone charging case, such as... Figure 3 As shown, the method in this embodiment includes the following steps:

[0047] Step S301: Obtain the attitude data of the earphone charging case detected by the attitude detection device.

[0048] Optionally, the attitude detection device may include a three-axis accelerometer to acquire attitude data of the earphone charging case detected by the attitude detection device. This may include: acquiring three-axis acceleration data of the earphone charging case detected by the three-axis accelerometer, wherein the three-axis acceleration data includes X-axis acceleration, Y-axis acceleration and Z-axis acceleration.

[0049] Before step S301, the control method for the earphone charging case may further include: initializing the accelerometer and display screen, and entering a safety monitoring mode; selecting different working modes according to the mode selection command input by the user; the working modes include at least an interactive mode and a motion-sensing game mode.

[0050] In this embodiment, the safety monitoring mode is a background-based safety monitoring system. Once the earphone charging case completes the initialization of the accelerometer and display screen, it directly enters the safety monitoring mode. The attitude detection device runs continuously in the background with low power consumption, collecting data such as three-axis acceleration. This embodiment can thus focus on identifying specific risk situations, improving the safety performance and reliability of the earphone charging case. Upon entering the safety monitoring mode, the controller can also select different operating modes based on user input. Selectable operating modes include the aforementioned interactive mode and motion-sensing game mode. This embodiment uses a unified hardware platform, and the software architecture includes a safety monitoring system that always runs in the background, and two foreground application systems available for user selection: an interactive system and a motion-sensing game system. All three share underlying three-axis sensor data, but the data processing logic, application objectives, and user interface are completely separated.

[0051] This embodiment provides a smart headphone charging case integrating a display screen and a posture detection device. Through an innovative data processing architecture, this charging case maps physical world posture changes and device state transitions into rich visual interactions. It can not only drive virtual avatars on the screen to achieve real-time synchronization and contextualized interaction with physical postures, but also independently run various motion-sensing games and applications, and possesses persistent background security monitoring capabilities. Thus, it upgrades a traditional charging accessory into a smart terminal integrating emotional interaction, entertainment functions, and security protection, completely reconstructing the product's functional value and user experience.

[0052] Step S302: In interactive mode, determine the motion posture of the earphone charging case based on the posture data, and control the display screen of the earphone charging case to display the motion image corresponding to the motion posture; the motion posture includes at least one of tilting posture and shaking posture.

[0053] Step S303: In motion-sensing game mode, determine the motion command of the earphone charging case based on posture data and motion-sensing game type; and control the display screen of the earphone charging case to display the game screen corresponding to the motion command according to the motion command; the motion command includes at least one of gesture command and shaking command.

[0054] Step S304: In safety monitoring mode, determine the risk posture of the earphone charging case based on posture data; and control the display screen of the earphone charging case to display the alarm screen corresponding to the risk posture according to the risk posture; the risk posture includes at least one of free fall, fall and impact.

[0055] Accordingly, determining the risk posture of the earphone charging case based on posture data can include: determining the composite acceleration vector based on three-axis acceleration data; if the difference between the composite acceleration vector and zero is less than a preset difference and continues for a first set time, the risk posture of the earphone charging case is determined to be free fall; if the difference between the composite acceleration vector and zero is less than a preset difference, and the composite acceleration vector is greater than or equal to a second preset amplitude within a preset time, the risk posture of the earphone charging case is determined to be falling; if any of the X-axis acceleration, Y-axis acceleration, Z-axis acceleration, and composite acceleration vector is detected to be greater than or equal to a third preset amplitude, the risk posture of the earphone charging case is determined to be impact.

[0056] In this embodiment, triaxial acceleration data is continuously monitored. When the difference between the composite acceleration vector and zero is less than a preset difference (the composite acceleration vector is close to zero), and this state continues for a first set time, the risk posture of the earphone charging case is determined to be free fall. The display screen can then show a virtual image of the falling object or display the flashing text "Free Fall" to remind the user to pick up the earphone charging case, preventing its loss and facilitating its timely retrieval if it falls. When the difference between the composite acceleration vector and zero is less than a preset difference, and the composite acceleration vector is greater than or equal to zero within a preset time... The second preset amplitude indicates that the earphone charging case has fallen and hit an obstacle after free fall. In this case, the display shows a virtual image of the earphone charging case falling or flashes the text "Fall Alarm" to remind the user to retrieve the earphone charging case. When it is detected that any of the X-axis acceleration, Y-axis acceleration, Z-axis acceleration, and the composite acceleration vector is greater than the third preset amplitude, it is determined that the earphone charging case has received a high G-value impact signal, which is generally a serious impact. In this case, the display shows a virtual image of the earphone charging case being hit or flashes the text "Caution Impact" to remind the user to quickly retrieve the earphone charging case.

[0057] Optionally, once the aforementioned risk posture is identified, the control module immediately triggers the alarm process. Specifically, the control method for the earphone charging case may further include: controlling the speaker of the earphone charging case and / or the earphones connected to the earphone charging case to send an alarm prompt tone corresponding to the risk posture, based on the risk posture of the earphone charging case. On one hand, this embodiment can generate alarm prompt tones through the speaker and earphones. For example, when the earphones are placed in the earphone charging case, an acoustic alarm is emitted through the speaker of the earphone charging case; when the earphones are removed from the earphone charging case, an acoustic alarm is emitted through the earphones to prompt the user to retrieve the earphone charging case in time and prevent the earphone charging case from being lost. The aforementioned alarm prompt tone can be a high-frequency, rapid warning tone.

[0058] This embodiment features a safety monitoring mode that immediately alerts the user via a display screen and acoustic alarm when the earphone charging case experiences risky actions such as freefall, drop, or impact, potentially preventing further drops or allowing for quick retrieval of the device after a fall. For the first time on the earphone charging case hardware platform, a parallel system architecture of "background safety monitoring + foreground dual applications" is proposed. This architecture implements a collaborative working mode consisting of a resident background process (safety monitoring) and two optional foreground applications (model interaction and motion-sensing games), ensuring uninterrupted core safety functions while providing diverse interactive and entertainment experiences. Furthermore, a multi-path parallel processing mechanism is established for the same three-axis accelerometer data source. The system can feed raw data into three processing pipelines according to different application objectives: an event detection pipeline for risk identification, a model-driven pipeline for attitude synchronization, and a command mapping pipeline for game control, thereby maximizing the value of single sensor data.

[0059] This invention also provides an earphone charging case. Figure 4 This is a schematic diagram of the structure of an earphone charging case provided in an embodiment of the present invention, as shown below.
