Description

Technical Field

[0001] This invention relates to the field of smart wearable devices, and in particular to a relaxation guidance method and a wearable device. Background Technology

[0002] Wearable devices (such as smart bracelets and smartwatches) can detect users' physiological indicators through built-in heart rate sensors and skin conductance sensors to analyze their emotional state or stress level. Some devices will issue simple alerts or push notifications when they detect that a user is under high stress, informing the user that they need to relax.

[0003] However, existing relaxation prompts are relatively simple, usually just providing reminders or fixed breathing training images. They cannot dynamically adjust relaxation strategies based on the user's real-time physiological feedback, nor can they provide personalized relaxation suggestions based on the user's current specific state (such as tension, fatigue, etc.). Summary of the Invention

[0004] The main objective of this invention is to provide a relaxation guidance method that aims to guide users into a relaxed state through vibration.

[0005] To achieve the above objectives, the relaxation guidance method provided by the present invention is applied to a wearable device, the wearable device comprising a plurality of vibration units arranged along a first direction and a detection module for detecting physiological parameters, the relaxation guidance method comprising: In response to the user's relaxation command, the detection module is driven to acquire the user's current physiological parameters; Based on a preset user emotion model, the user's current emotional state is determined according to the current physiological parameters. Based on the current emotional state, a corresponding vibration command is generated; According to the vibration command, the corresponding vibration unit is controlled to vibrate.

[0006] In one embodiment of the present invention, the step of generating a corresponding vibration command based on the current emotional state includes: Based on the current emotional state, obtain the emotional deviation information between the current emotional state and the target relaxed state; The vibration command is generated based on the emotional deviation information.

[0007] In one embodiment of the present invention, the step of generating the vibration command based on the emotional deviation information includes: Based on the preset deviation vibration mapping rules, vibration parameters are determined according to the emotional deviation information; The vibration command is generated based on the vibration parameters.

[0008] In one embodiment of the present invention, after the step of controlling the corresponding vibration unit to vibrate according to the vibration command, the method further includes: After the vibration unit finishes vibrating, the detection module is driven to obtain the user's latest physiological parameters; Based on the latest physiological parameters and the user emotion model, determine whether the user has entered a relaxed state; When the user is not in a relaxed state, the corresponding vibration unit is controlled to vibrate according to the latest physiological parameters.

[0009] In one embodiment of the present invention, the relaxation guidance method further includes: Receive the user's relaxation selection command and determine the preset relaxation guidance mode; Based on the relaxation guidance mode, a corresponding vibration command is generated; According to the vibration command, the corresponding vibration unit is controlled to vibrate.

[0010] In one embodiment of the present invention, the step of receiving a user's relaxation selection instruction and determining a preset relaxation guidance mode includes: Receive relaxation selection instructions input by the user through the interaction module of the wearable device, and / or receive relaxation selection instructions input by the user through an external device; Parse the relaxation selection command to obtain the corresponding mode identifier; Based on the mode identifier, the corresponding preset relaxation guidance mode is called from the pre-stored relaxation mode library.

[0011] In one embodiment of the present invention, after receiving the user's relaxation selection instruction and determining the preset relaxation guidance mode, the method further includes: The detection module is driven to acquire the user's current physiological parameters; Based on the current physiological parameters, calculate the degree of matching between the current emotional state and the target relaxation state corresponding to the determined preset relaxation guidance mode; When the current emotional state does not match the target relaxed state, a first prompt message is generated.

[0012] In one embodiment of the present invention, after the step of generating the first prompt information when the current emotional state does not match the target relaxation state, the method further includes: Based on the current physiological parameters, a second prompt message containing an alternative relaxation guidance mode is generated; In response to the user's selection command, the corresponding vibration unit is controlled to vibrate according to the selected alternative relaxation guidance mode.

[0013] In one embodiment of the present invention, after the step of calculating the matching degree between the current emotional state and the target relaxation state corresponding to the determined preset relaxation guidance mode based on the current physiological parameters, the method further includes: When the current emotional state matches the target relaxation state, the corresponding vibration unit is controlled to vibrate according to the determined preset relaxation guidance mode.

[0014] The present invention also proposes a wearable device, the wearable device comprising: A detection module configured to acquire the user's physiological parameters; Multiple vibration units, each vibration unit being arranged along a first direction; and A controller electrically connected to each of the vibration units and the detection module, the controller being configured to perform the relaxation guidance method as described in any one of the above.

[0015] Beneficial technical effects In this technical solution, the relaxation guidance method provided by the present invention employs multiple vibration units arranged along a first direction and a detection module for detecting physiological parameters. Based on a preset user emotion model, the method determines the user's current emotional state according to the current physiological parameters, and then generates corresponding vibration commands based on the emotional state to control the vibration of the vibration units at the corresponding positions. This solves the problems of the prior art, such as the single relaxation prompt method, the inability to dynamically adjust the relaxation strategy according to the user's real-time physiological feedback, and the difficulty in providing personalized relaxation suggestions. Specifically, when a user issues a relaxation command, the detection module collects physiological parameters such as heart rate and skin conductance in real time. The user's emotion model maps these parameters to specific emotional states (such as tension, fatigue, etc.), thereby identifying the user's current true psychological needs. Then, the controller generates a matching vibration command based on the identified emotional state. By combining the spatial position, vibration intensity, duration, and timing of multiple vibration units in the first direction, a vibration sequence is formed that can produce differentiated tactile effects for different emotional states—for example, outputting slow and gentle wave vibrations for tension, outputting clearly defined stimulating vibrations for fatigue, and outputting rhythmic guidance that starts fast and then slows down for excitement. By driving the vibration units at the corresponding positions to execute this vibration sequence, the user can be guided into a relaxed state solely through the touch of their wrist, without any visual or auditory assistance. Thus, this invention achieves closed-loop personalized relaxation guidance based on real-time physiological feedback, significantly improving the targeting and effectiveness of relaxation strategies and enhancing the user experience.

[0021] The main objective of this invention is to provide a relaxation guidance method that aims to guide users into a relaxed state through vibration.

[0022] To achieve the above objectives, the relaxation guidance method provided by this invention is applied to a wearable device. The wearable device includes multiple vibration units arranged along a first direction and a detection module for detecting physiological parameters. Please refer to [link to relevant documentation]. Figure 1 Relaxation guidance methods include: S10: Responding to the user's relaxation command, drive the detection module to obtain the user's current physiological parameters; S20: Based on a preset user emotion model, determine the user's current emotional state according to current physiological parameters; S30: Generates corresponding vibration commands based on the current emotional state; S40: Controls the corresponding vibration unit to vibrate according to the vibration command.

[0023] First, it needs to be explained that the wearing device proposed in this invention is explained using a wristband-type wearing device as an example, but it is not limited to this. It can also be other structural forms that can be worn on the wrist, such as a bracelet, watch, armband, or ring.

[0024] The wearable device mainly consists of two parts: a flexible wristband and a functional integration module. The flexible wristband can be made of skin-friendly materials such as silicone, fabric, or elastic plastic, and is strip-shaped. Its two ends are connected to the two sides of the frame of the functional integration module, forming a closed-loop structure for the user to wear on their wrist. Multiple vibration units are installed in the flexible wristband, arranged along a first direction (i.e., the circumference of the wrist, extending from the palm side to the back of the hand). Each vibration unit can be a linear resonant actuator (LRA), an eccentric rotating mass motor (ERM), or a piezoelectric ceramic vibrator. These vibration units can be electrically connected to the controller in the functional integration module via a flexible printed circuit board (FPC).

[0025] The functional integration module includes at least a rigid frame (typically made of metal or plastic) that serves as the supporting skeleton for the entire wearable device. The surface of this frame integrates a display screen, while the internal components include a detection module, buttons or touch sensors, a battery, a wireless communication module, and a controller (microcontroller (MCU) or digital signal processor (DSP)). The frame of the functional integration module is connected to both ends of a flexible wristband.

[0026] When worn, the functional integration module is usually located on the back of the wrist (back of the hand), while the flexible wristband wraps around the palm side and both sides of the wrist.

[0027] The detection module includes at least a PPG module (which uses photoplethysmography to detect heart rate and heart rate variability) and an EDA module (which detects skin conductance levels). The PPG module and EDA module are usually located at the bottom of the functional integration module to more accurately measure the user's physiological parameters.

[0028] In step 10, the controller responds to the user's relaxation command and drives the detection module to acquire the user's current physiological parameters. Specifically, when the user issues a relaxation command through a button on a wearable device (such as a smart bracelet or smartwatch), a touchscreen, or a compatible external device (such as a mobile app), the controller immediately activates the detection module. The detection module continuously collects the user's physiological signals within a preset time window (e.g., 10 to 30 seconds) and obtains stable and reliable current physiological parameters through preprocessing algorithms such as filtering and noise reduction. These parameters objectively reflect the user's current autonomic nervous system state, providing basic data for subsequent emotion recognition.

[0029] In step 20, the controller determines the user's current emotional state based on a preset user emotion model and current physiological parameters. The preset user emotion model is a personalized classifier trained using machine learning algorithms (such as support vector machines, random forests, or lightweight neural networks) by pre-collecting physiological data such as heart rate, high-frequency HRV (HF), and skin conductance response level of the user under various typical emotional states (such as resting relaxation, tension, excitement, depression, and fatigue).

[0030] The user emotion model can map the current physiological parameters obtained in step 10 to specific emotional state labels, such as "nervous," "excited," "depressed," or "relaxed." Because different individuals have different physiological baselines, the model can adaptively update based on users' long-term usage data, thereby continuously improving the accuracy of emotion recognition.

[0031] In step 30, the controller generates a corresponding vibration command based on the current emotional state. Specifically, the controller selects a matching vibration pattern from a pre-stored vibration parameter library based on the identified current emotional state. The definition of the vibration pattern includes multiple parameters, such as the spatial position sequence of the vibration units (determining the direction and range of tactile movement on the wrist), the activation interval between adjacent vibration units (determining the speed of tactile propagation), the vibration intensity envelope of each vibration unit (determining the gentleness or intensity of the tactile sensation), the duration of a single vibration, and the vibration frequency.

[0032] For example, when a "tense" state is detected, the system generates a wave-like vibration command that is slow, gentle, and has a long cycle; when an "excited" state is detected, a massage-like vibration command with a faster rhythm and moderate intensity is generated first, and then gradually transitions to a soothing mode; when a "depressed" state is detected, a fixed-point pressing vibration command with clear points and a sense of encouragement is generated.

[0033] In step 40, the controller controls the corresponding vibration unit to vibrate according to the vibration command. Specifically, the controller parses the generated vibration command into a drive signal and inputs it to one or more vibration units. Based on the spatial position code in the vibration command, the controller selects one or more corresponding vibration units as target units; based on the timing and intensity codes, it controls these units to generate mechanical vibrations according to a preset sequence, time interval, and intensity envelope. The user's wrist skin will perceive a tactile sequence with specific spatial position changes and rhythm, thus being guided into a relaxed state without visual or auditory intervention.

[0034] Regarding step 40, although the palmar side of the wrist (wrist crease, Neiguan / Shenmen acupoint area) lacks C-tactile (CT) emotional fibers, it is densely covered with Meissner bodies and lamellar bodies. These vibration mechanoreceptors are all innervated by Aβ thick myelin sheath nerves (median nerve trunk). Aβ fibers are most sensitive to low-frequency vibrations of 5–50 Hz. When the vibration unit operates within this frequency range, it can efficiently activate Aβ fibers. Simultaneously, the median nerve signal ascends to the nucleus tractus solitarius (NTS) in the brainstem. The NTS is a key upstream node of the vagus nerve (parasympathetic nerve) center and plays an important regulatory role in the balance of the autonomic nervous system.

[0035] Therefore, low-frequency vibration stimulation on the palm side can effectively activate the nucleus tractus solitarius via the Aβ-median nerve pathway, thereby promoting parasympathetic nerve excitation and inhibiting sympathetic nerve activity, resulting in a sedative effect such as slowed heart rate, calmed breathing, and muscle relaxation.

[0036] It is understood that the vibration frequency in this scheme can be obtained from multiple human experiments to obtain the optimal range. For example, by comparing the improvement effect of different frequencies (such as 5HZ, 10HZ, 20Hz, 30Hz, 40Hz, 50Hz) on the high frequency power (HF) of heart rate variability, the frequency range with the best effect can be selected, but the specific value is not a limitation of this invention.

[0037] In one application scenario, a user experiencing tension can click the "Relaxation Guidance" icon on the display to issue a relaxation command. Upon receiving this command, the controller drives the PPG and EDA sensors to collect current physiological parameters, detecting a faster heart rate, lower HRV high-frequency power, and higher skin conductance. Based on a preset user emotion model, the controller maps these parameters to a "mild tension" emotional state. Subsequently, based on the tension state, it generates a flowing vibration command that slowly moves from the center of the palm to the outside, with appropriate activation intervals between adjacent units, gradual increase and decrease in intensity, and a low frequency. Finally, it controls the palm-side vibration units to activate sequentially outward, allowing the user to feel a gentle vibration sliding from the inside to the outside of their wrist. Throughout this process, the user does not need to look at the screen or listen to voice commands; simply by sensing the tactile changes from flowing to single-point vibrations on their wrist, they can gradually transition from tension to relaxation under closed-loop guidance, achieving efficient and personalized relaxation guidance.

[0038] In this technical solution, the relaxation guidance method provided by the present invention employs multiple vibration units arranged along a first direction and a detection module for detecting physiological parameters. Based on a preset user emotion model, the method determines the user's current emotional state according to the current physiological parameters, and then generates corresponding vibration commands based on the emotional state to control the vibration of the vibration units at the corresponding positions. This solves the problems of the prior art, such as the single relaxation prompt method, the inability to dynamically adjust the relaxation strategy according to the user's real-time physiological feedback, and the difficulty in providing personalized relaxation suggestions. Specifically, when a user issues a relaxation command, the detection module collects physiological parameters such as heart rate and skin conductance in real time. The user's emotion model maps these parameters to specific emotional states (such as tension, fatigue, etc.), thereby identifying the user's current true psychological needs. Then, the controller generates a matching vibration command based on the identified emotional state. By combining the spatial position, vibration intensity, duration, and timing of multiple vibration units in the first direction, a vibration sequence is formed that can produce differentiated tactile effects for different emotional states. For example, a slow and gentle wave vibration is output for a tense state, a clearly defined stimulating vibration is output for a fatigued state, and a rhythmic guidance that is fast at first and then slows down for an excited state. By driving the vibration unit at the corresponding position to execute the vibration sequence, the user can be guided into a relaxed state by touch alone, without any visual or auditory assistance.

[0039] In one embodiment of the present invention, please refer to Figure 2 Step 30 includes: S31: Based on the current emotional state, obtain information on the emotional deviation between the current emotional state and the target relaxed state; S32: Generate vibration commands based on emotional deviation information.

[0040] In step 31, the controller compares the identified current emotional state with a pre-set target relaxation state to obtain emotional deviation information. The target relaxation state can be a personalized relaxation baseline established based on the user's physiological parameters at rest, such as a moderate heart rate, high HRV high-frequency power, and low skin conductance. Compared to a general fixed physiological threshold, using a user-specific resting baseline for benchmarking can effectively avoid individual physiological differences between different users, significantly improving the accuracy and personalized adaptation of emotional deviation judgment. Emotional deviation information includes at least two dimensions: deviation direction and deviation magnitude.

[0041] Among them, the deviation direction is used to characterize the abnormal type of the user's current emotion deviating from the relaxed state. Specifically, it can correspond to three typical emotional deviation scenarios: when the current state is tense, it is manifested as sympathetic nerve hyperactivity and parasympathetic nerve inhibition; when the current state is excited or agitated, it is manifested as excessive neural activity and disordered physical and mental rhythms; when the current state is depressed or tired, it is manifested as insufficient sympathetic nerve activity and low physical and mental tension.

[0042] The deviation magnitude is used to characterize the degree to which the current emotional state deviates from the target relaxed state. It can be divided into three levels: mild deviation, moderate deviation, and severe deviation. It can transform the user's qualitative emotional labels into quantifiable and gradeable deviation parameters.

[0043] In step 32, the controller generates corresponding vibration commands based on the obtained emotional deviation information. These vibration commands are used to subsequently drive the vibration unit to produce specific tactile effects, achieving targeted correction of the user's emotional state. Different types and gradients of emotional deviation information correspond to completely differentiated vibration commands, forming an adaptive control logic of "deviation type matching vibration mode, and deviation gradient matching vibration intensity and duration."

[0044] For example, when the emotional deviation is small, with only slight emotional deviation, a gentle, short-duration sustaining vibration stimulus is output to help the user maintain a stable and relaxed state. When the emotional deviation is large, with a higher degree of emotional deviation, a moderately intense, more varied, and longer-lasting corrective vibration stimulus is output to effectively intervene in abnormal emotional states. In this way, vibration commands can be matched with the user's current degree of emotional deviation, achieving personalized relaxation guidance.

[0045] Further, please refer to Figure 3 Step 32 includes: S321: Based on the preset deviation vibration mapping rule, determine the vibration parameters according to the emotional deviation information; S322: Generate vibration commands based on vibration parameters.

[0046] In step 321, the controller queries the preset deviation vibration mapping rules based on the obtained emotional deviation information. The deviation vibration mapping rules define the one-to-one correspondence between different emotional deviation directions, different deviation degrees and various vibration parameters, and are used to realize the correction logic of "outputting the corresponding vibration intervention strategy based on which emotional indicator of the user deviates and to what extent".

[0047] The vibration parameters may include: the spatial position sequence of the vibration units (which determines the movement path and coverage of the tactile sensation on the wrist), the activation interval between adjacent vibration units (which determines the speed of tactile transmission and the overall rhythm), the vibration intensity envelope (which determines the gentleness or intensity of the tactile sensation and supports dynamic changes such as gradual rise and fall, and gradual increase and decrease), vibration duration, and vibration frequency, among other multi-dimensional core parameters.

[0048] Through this mapping rule, the controller can transform abstract, qualitative emotional deviation information into specific, quantifiable, and hardware-executable vibration control parameters, allowing the vibration output to adapt to the user's current emotional deviation state and ensuring the effectiveness of relaxation intervention.

[0049] In step 322, the controller generates vibration commands that can be directly executed by the drive circuit based on a determined set of vibration parameters.

[0050] The vibration command includes specific control information such as the vibration unit to be activated, the start time of each vibration unit, the vibration duration, the intensity change curve, and the vibration frequency. After the command is sent to the drive circuit, it can control the corresponding vibration unit to generate mechanical vibration according to the preset sequence, intensity, duration, and frequency. Ultimately, through tactile stimulation of the dedicated neural pathway on the palm side of the wrist, it guides the user's autonomic nervous system to restore balance and achieves emotional relaxation.

[0051] In one embodiment of the present invention, please refer to Figure 4 After step 40, the following also includes: S50: After the vibration unit finishes vibrating, drive the detection module to obtain the user's latest physiological parameters; S60: Based on the latest physiological parameters and user emotion models, determine whether the user has entered a relaxed state; S70: When the user is not in a relaxed state, the corresponding vibration unit is controlled to vibrate according to the latest physiological parameters.

[0052] In step 50, after the vibration unit completes the preset vibration sequence, the controller immediately drives the detection module to collect the user's physiological parameters again. Here, "latest physiological parameters" refers to the user's current physiological indicators after the completion of a single vibration guidance cycle, including heart rate, heart rate variability high-frequency power (HRV-HF), and skin conductance response level. By updating the physiological data promptly after each vibration cycle, the system can assess the initial effect of the vibration and provide a basis for subsequent adjustments.

[0053] In step 60, the controller, based on the latest acquired physiological parameters, calls the preset user emotion model again to map the physiological parameters to the current user emotional state and determines whether the emotional state has reached the target relaxation state. If all indicators of the current emotional state fall within the preset tolerance range of the target relaxation state, the user is determined to have successfully relaxed; if any indicators deviate, the user is determined not to have reached a relaxation state.

[0054] In step 70, when step 60 determines that the user has not yet entered a relaxed state, the controller will determine the current emotional state based on the user's emotional model according to the latest physiological parameters obtained in step 50, generate the corresponding vibration command, and control the vibration unit to vibrate again.

[0055] Specifically, the controller calculates the new emotional deviation from the target relaxed state based on the latest physiological parameters, and adjusts the parameters of the next round of vibration accordingly (e.g., changing the vibration mode, intensity, speed, or spatial position sequence), and then drives the corresponding vibration unit to execute. This process is repeated until the user enters a relaxed state or receives a stop command.

[0056] Through this closed-loop feedback mechanism, the relaxation guidance method of the present invention can continuously track the user's physiological changes, dynamically optimize the vibration strategy, and significantly improve the relaxation effect and personalization.

[0057] In one application scenario, after the first round of flowing vibration relaxation guidance for the user's tense state ends, the controller drives the detection module to re-collect the user's latest physiological parameters after a very short preset time interval or immediately, and completes a secondary state determination in combination with the user's emotional model.

[0058] At this point, the user's heart rate was still slightly higher than the individual's resting baseline, and the skin conductance level had not yet fully returned to the relaxation range. However, compared to the initial state before the intervention, all core physiological indicators had clearly converged towards the target relaxation state. The controller determined that the user had not yet fully entered the standard relaxation state, but the overall mood was in the process of continuous improvement, and there was no need for high-intensity corrective vibration intervention.

[0059] Based on this determination, the controller adaptively adjusts the vibration parameters for this round, switching from the previous round's flow vibration mode adapted for tension correction to a lower-intensity, slower-rhythm single-point sustained vibration mode. Through gentle and stable fixed-point tactile stimulation, it continuously soothes the user's tense nerve state, gradually guiding the user's heart rate to further decrease and skin conductance level to gradually stabilize, until the user's various physiological indicators match the personalized target relaxation baseline, ultimately completing the complete loop relaxation guidance process.

[0060] In one embodiment of the present invention, please refer to Figure 5 Relaxation guidance methods also include: S11: Receive the user's relaxation selection command and determine the preset relaxation guidance mode; S12: Generates corresponding vibration commands based on the relaxation guidance mode; S13: Control the corresponding vibration unit to vibrate according to the vibration command.

[0061] Specifically, the relaxation guidance method proposed in this invention, in addition to the relaxation guidance mode based on the user's physiological state, is also equipped with a preset relaxation guidance mode that can be selected by the user, realizing dual-mode compatible control of adaptive and user-selected modes, and adapting to the usage habits and scenario needs of different users.

[0062] In step 11, the controller receives the user's relaxation selection command and determines the preset relaxation guidance mode. The controller receives the user's actively input relaxation selection command through an interactive module on the wearable device (such as a touch screen or physical buttons) or through wireless communication with an external device (such as a mobile app).

[0063] The relaxation selection command carries an identifier for the user's desired relaxation mode, such as "massage for stress relief," "guided breathing," or "white noise for sleep." Based on this identifier, the controller retrieves the corresponding preset relaxation guidance mode from a relaxation mode library stored locally or on a cloud server.

[0064] Each preset mode contains a fixed sequence of vibration parameters, such as the spatial order of vibration units, vibration intensity envelope, vibration duration, and activation interval of adjacent vibration units, which can be executed without relying on real-time physiological parameters.

[0065] In step 12, the controller generates a corresponding vibration command based on the relaxation guidance mode. Specifically, the controller converts the vibration parameter sequence corresponding to the preset relaxation guidance mode into a vibration command that can be directly executed by the drive circuit. This command specifies the vibration units to be activated, the start-up time of each vibration unit, the vibration duration, the intensity change curve, and the vibration frequency, among other control information.

[0066] In step 13, the controller controls the corresponding vibration unit to vibrate according to the vibration command. The controller sends the generated vibration command to the drive circuit, driving one or more corresponding units among the multiple vibration units to generate mechanical vibration according to the spatial order, timing interval, intensity envelope and vibration frequency set in the command.

[0067] Users perceive a tactile sequence corresponding to the selected pattern through the skin of their wrists, such as wave-like flow, fixed-point pressure, or breath-synchronized rise and fall, thereby achieving relaxation guidance.

[0068] In one embodiment of the present invention, please refer to Figure 6 Step 11 includes: S111: Receive relaxation selection instructions input by the user through the interaction module of the wearable device, and / or receive relaxation selection instructions input by the user through an external device; S112: Parse the relaxation selection command to obtain the corresponding mode identifier; S113: Based on the mode identifier, call the corresponding preset relaxation guidance mode from the pre-stored relaxation mode library.

[0069] In step 111, the controller can receive the user's relaxation selection command through two methods. The first method is directly through the wearable device's local interaction module, such as a mode selection menu displayed on a touchscreen, physical buttons, or a rotating crown; the user clicks or presses to generate the corresponding command. The second method is receiving commands from external devices via wireless communication (such as Bluetooth or Wi-Fi). For example, after the user selects a relaxation mode on a mobile app, the app sends the command to the wearable device. Both methods can be used individually or simultaneously, allowing the user to choose flexibly according to their usage habits.

[0070] In step 112, the controller parses the received relaxation selection command and extracts the mode identifier carried within it. This mode identifier is a preset numerical code, character code, or label identifier, with each type of identifier corresponding one-to-one with a relaxation guidance mode, ensuring the uniqueness and accuracy of mode recognition and avoiding pattern matching errors. If the command is input through the local interaction module, the controller can directly convert the button number or menu option into an internal identifier; if the command comes from an external device, it is decoded according to the communication protocol to obtain a clear mode identifier.

[0071] In step 113, the controller retrieves the corresponding preset relaxation guidance mode from the pre-stored relaxation mode library based on the mode identifier. The relaxation mode library is a set of parameters pre-stored in local memory or a cloud server. The library contains a variety of standardized vibration modes adapted to different physical and mental states such as tension, excitement, depression, and general relaxation. Each mode is pre-configured with a set of fixed parameters such as independent vibration spatial position, temporal rhythm, frequency, intensity, and duration. By matching the mode identifier, the target relaxation mode can be quickly and accurately retrieved, providing a reliable basis for subsequent generation of standardized vibration commands and execution of fixed tactile relaxation guidance.

[0072] To verify whether the preset relaxation mode selected by the user matches their current emotional state, please refer to [link / reference]. Figure 7 Step 11 and the following steps also include: S14: Drive the detection module to obtain the user's current physiological parameters; S15: Based on the current physiological parameters, calculate the degree of matching between the current emotional state and the target relaxation state corresponding to the determined preset relaxation guidance mode; S16: When the current emotional state does not match the target relaxed state, generate the first prompt message.

[0073] In step 14, the controller drives the detection module to acquire the user's current physiological parameters. Specifically, after the user selects a preset relaxation guidance mode, the controller immediately drives the detection module to collect the user's current physiological parameters, including heart rate, heart rate variability high-frequency power (HRV-HF), and skin conductance response level. These parameters objectively reflect the user's current autonomic nervous system state, providing basic data for subsequent matching degree calculations.

[0074] In step 15, the controller calculates the matching degree between the current emotional state and the target relaxation state corresponding to the determined preset relaxation guidance mode based on the current physiological parameters. The controller maps the current physiological parameters collected in step 14 to the user's current emotional state (e.g., tension, excitement, depression, or relaxation) based on a preset user emotion model. Simultaneously, each preset relaxation guidance mode corresponds to an ideal target relaxation state.

[0075] The controller calculates the degree of match between the current emotional state and the ideal state corresponding to the pattern, which can be quantified by methods such as Euclidean distance, cosine similarity, or classification confidence. The higher the degree of match, the more suitable the user's current state is for the pattern; the lower the degree of match, the less likely the pattern will achieve the expected relaxation effect.

[0076] In step 16, a first prompt message is generated when the current emotional state does not match the target relaxation state. When the calculated matching degree is lower than a preset threshold (e.g., matching degree less than 0.5), the controller determines that the current emotional state does not match the preset relaxation guidance mode. At this time, the controller will generate a first prompt message, which is used to inform the user that the currently selected mode does not match their own state, reminding the user that they may need to change the mode or use other relaxation methods.

[0077] The first prompt message can be output in at least one of the following ways: controlling the vibration unit of the wearable device to vibrate with a preset prompt vibration sequence (such as two short vibrations); displaying a text prompt (such as "The current mode does not match your status") on the display screen of the wearable device; or sending a prompt message to an external device (such as a mobile phone app) via wireless communication.

[0078] In one embodiment of the present invention, please refer to Figure 8 Step 16 is followed by: S17: Based on current physiological parameters, generate a second prompt message containing an alternative relaxation guidance mode; S18: In response to the user's selection command, control the corresponding vibration unit to vibrate according to the selected alternative relaxation guidance mode.

[0079] In step 17, the controller generates a second prompt message containing alternative relaxation guidance modes based on the current physiological parameters. When the controller determines that the user's current emotional state does not match the selected mode, the controller further selects one or more alternative relaxation guidance modes with a high degree of matching with the current emotional state from the pre-stored relaxation mode library based on the current physiological parameters collected in step 14.

[0080] Specifically, the controller inputs the current physiological parameters into the user's emotion model to obtain the current emotion state label; then it iterates through the relaxation mode library, calculates the matching degree between the current emotion state and the ideal state corresponding to each mode, and selects the one or several modes with the highest matching degree as alternative options.

[0081] The controller then generates a second prompt message to inform the user that the current mode is not a match, and also explicitly includes the name, number, or brief description of the alternative relaxation guide mode (e.g., "We recommend trying the 'Wave Relaxation' mode").

[0082] The second prompt can be presented as text or icons on the wearable device's display screen, or as a push notification from an external device (such as a mobile app), or as a tactile prompt via a vibration unit using a specific encoded sequence (such as different modes corresponding to different vibration rhythms).

[0083] In step 18, the controller responds to the user's selection command and controls the corresponding vibration unit to vibrate according to the selected alternative relaxation guidance mode. Specifically, after receiving the second prompt, if the user is willing to accept the recommended alternative mode, they can issue a selection command through the interactive module of the wearable device (such as a touch screen or button) or an external device (such as a mobile app), for example, by clicking the "switch" button or directly clicking the recommended mode icon.

[0084] After receiving the selection command, the controller parses the mode identifier of the user-specified alternative relaxation guidance mode, retrieves the corresponding vibration parameter sequence from the relaxation mode library, generates a vibration command, and drives the corresponding vibration unit to perform vibration operations according to preset parameters such as spatial position, timing, intensity, and frequency. If the user ignores the prompt or does not make a selection, the system can maintain the original mode or exit automatically.

[0085] Through this mechanism, the relaxation guidance method proposed in this invention can proactively recommend a better solution when the user's selected mode is not suitable for the current state, and allow the user to switch with one click, thereby improving the intelligence level of relaxation guidance and user experience.

[0086] In one embodiment of the present invention, step 15 is followed by: When the current emotional state matches the target relaxation state, the corresponding vibration unit is controlled to vibrate according to the predetermined preset relaxation guidance mode.

[0087] Specifically, if the matching degree calculated in step 15 reaches or exceeds the preset threshold, it is determined that the current emotional state matches the ideal relaxation state corresponding to the preset relaxation guidance mode selected by the user, that is, the mode is suitable for the user's current physical and mental state.

[0088] At this time, the controller does not need to generate any prompts. Instead, it directly calls the vibration parameter sequence corresponding to the preset relaxation guidance mode, generates vibration commands, and drives the corresponding vibration units arranged along the first direction to perform vibration operations according to the preset spatial position sequence, time interval, intensity envelope, and vibration frequency, so that the user can start relaxation guidance immediately.

[0089] This step allows the controller to respond and execute quickly when the user's selected mode is suitable for the current state, avoiding unnecessary prompts and waiting, and improving the efficiency of relaxation guidance and user experience.

[0090] The present invention also proposes a wearable device, which includes a detection module, multiple vibration units, and a controller. The detection module is configured to acquire the user's physiological parameters. Each vibration unit is arranged along a first direction. The controller is electrically connected to each vibration unit and the detection module, and is configured to execute the relaxation guidance method as described above. Since the wearable device proposed by the present invention adopts all the technical solutions of the above-described relaxation guidance method embodiments, it has at least all the beneficial effects brought about by the above embodiments, which will not be elaborated here.
