Description

Technical Field

[0001] This application relates to the field of smart wearable technology, and in particular to an information prompting method, a wearable interactive device, and a storage medium. Background Technology

[0002] Wearable interactive devices refer to intelligent electronic devices that can be worn on the surface of the human body (such as the wrist, head, ears, etc.) and have information processing and feedback capabilities. Typical forms include smartwatches, wireless headphones, and virtual reality glasses.

[0003] While existing wearable interactive devices can convey information to users through visual displays, voice broadcasts, and vibration feedback, these methods offer extremely limited information dimensions. Essentially, they only express a binary state of presence or absence of a reminder, lacking directional vector information. With the widespread adoption of such devices, human-computer interaction is gradually evolving from screen-touch-dependent visual interaction to screenless, immersive, and natural interaction. Simultaneously, scenarios requiring high levels of concentration, such as outdoor cycling, fitness activities, and driving, are increasingly common, making the need for efficient navigation information acquisition ever more urgent for users who cannot continuously view screens or listen to voice prompts. Summary of the Invention

[0004] This application provides an information prompting method, a wearable interactive device, and a storage medium, aiming to solve the technical problem that existing wearable interactive devices have a single information feedback dimension, making them difficult to adapt to complex interactive scenarios requiring directional guidance, such as navigation. Accordingly, the technical solution disclosed in this application is as follows: In a first aspect, embodiments of this disclosure provide an information prompting method applied to a wearable interactive device. The wearable interactive device includes a wearable body adapted to a part of the human body, and the wearable body is provided with a plurality of electrostatic adsorption poles, each of which generates an electrostatic adsorption tactile sensation when energized; wherein, the method includes: In response to the interactive commands of the target application, determine the direction of the target vector; Based on the target vector direction, at least one target electrostatic adsorption pole is determined from all the electrostatic adsorption poles, and the at least one target electrostatic adsorption pole corresponds to the target vector direction. The target electrostatic adsorption pole is energized so that the target vector direction is indicated to the user through the electrostatic adsorption tactile sensation generated at the location of the target electrostatic adsorption pole.

[0005] In a second aspect, embodiments of this disclosure provide a wearable interactive device, comprising: The main body of the wearable device has a contact surface that conforms to the parts of the human body that are worn with it; Multiple electrostatic adsorption poles are disposed on the contact surface, and each electrostatic adsorption pole generates an electrostatic adsorption tactile sensation when energized. The main control module is configured to execute the method described in the first aspect.

[0006] Thirdly, embodiments of this disclosure provide a computer-readable storage medium for storing computer-executable instructions that, when executed by a processor, implement the method described in the first aspect.

[0007] In summary, this disclosure proposes an information prompting scheme for wearable interactive devices. The wearable interactive device includes a wearable main body adapted to the body part of the wearer. The wearable main body has multiple electrostatic adsorption poles. When energized, each electrostatic adsorption pole generates a local electrostatic adsorption tactile sensation at its respective location, thereby constructing multiple independent tactile feedback points at different locations on the skin surface. The corresponding information prompting process includes: firstly, responding to the interaction command of the target application, determining the target vector direction to be prompted to the user; this target vector direction is the directional information to be conveyed in scenarios such as navigation; then, based on the target vector direction, determining at least one target electrostatic adsorption pole corresponding to the target vector direction from all electrostatic adsorption poles; subsequently, energizing the target electrostatic adsorption pole, causing it to generate a local electrostatic adsorption tactile sensation at its location. The spatial location of this tactile sensation is consistent with the target vector direction. The user can directly obtain the prompted direction by perceiving the specific location of the tactile sensation, without needing to look at the screen or listen to voice commands. In the above manner, the embodiments of this disclosure map vector information such as navigation direction into local electrostatic adsorption tactile sensations at different spatial locations on the skin, thereby achieving the encoding and transmission of directional information at the tactile level. This overcomes the limitation of existing wearable interactive devices that can only express whether there is a reminder but cannot transmit directional information, and provides a directional information feedback scheme for wearable interactive devices that is suitable for complex interactive scenarios such as navigation, without visual or auditory tactile feedback.

Detailed Implementation

[0010] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0011] As mentioned earlier, while current wearable interactive devices have formed a multi-channel feedback system encompassing sight, hearing, and touch, they still face significant limitations in practical applications. Visual displays require users to actively look at the screen and continuously focus on the displayed content. In scenarios such as cycling or driving, where attention needs to be focused on road conditions, shifting gaze can pose significant safety hazards. Voice broadcasts are easily masked by ambient noise in noisy environments, leading to information transmission failure and interfering with the user's perception of external sounds. Mainstream vibration feedback is limited by the physical structure of a single motor, producing only a uniform, undifferentiated vibration sensation, unable to differentiate the spatial location of touch. Crucially, although the above three feedback methods cover different sensory channels, their information carrying capacity is extremely limited. Essentially, they can only express a binary state of having or not having a reminder, unable to convey directional vector information. When applied to complex interactive scenarios requiring directional guidance, such as navigation, users have to frequently interrupt their current focused task to check the screen to confirm their location, making it difficult to effectively guarantee both interaction efficiency and safety. In view of this, this application provides a wearable interactive device and navigation method, aiming to overcome the limitation of existing devices that can only express binary states by mapping vector information to spatial tactile differences on the skin surface, thereby solving the problem of efficient and audiovisual-free directional guidance in complex scenarios. The technical solutions provided by various embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0012] On one hand, this disclosure provides an information prompting method for wearable interactive devices. The wearable interactive device includes a wearable main body adapted to the body, and the wearable main body has multiple electrostatic adsorption poles. Each electrostatic adsorption pole generates an electrostatic adsorption tactile sensation when energized. Based on the above structure, the method of this embodiment conveys directional information to the user through electrostatic adsorption tactile sensation, completing the prompt without relying on visual or auditory channels. Wherein, Figure 1 This is a flowchart illustrating the information prompting method of this embodiment, which specifically includes the following steps: S101, in response to the interactive command of the target application, determines the target vector direction.

[0013] At the beginning of the information prompting process, it is first necessary to determine the target vector direction to which the prompt should be directed. The interaction commands received by the wearable interactive device come from different types of target applications, such as navigation applications, sports applications, or message reminder applications. It should be noted that the above-mentioned target applications can run on external terminals (such as smartphones, tablets, etc.). The external terminal establishes a connection with the wearable interactive device of this embodiment through a wireless communication link and sends the interaction commands generated by the target application to the wearable interactive device. Alternatively, the target application can run directly on the wearable interactive device itself, where the processor inside the wearable interactive device executes the relevant logic of the target application and directly generates interaction commands. Regardless of whether the target application is deployed on an external terminal or on the wearable interactive device itself, the interaction commands it sends are transmitted to the main control module of the wearable interactive device for unified parsing and processing. Subsequent processing is not affected by the difference in the deployment location of the target application. The information content and information structure carried by the interaction commands sent by different applications are different: some commands have clearly indicated the direction, while others are only used to activate a certain function and do not yet contain specific spatial direction information. Therefore, upon receiving an interactive command, the command content needs to be parsed and judged to extract or gradually determine the directional information that needs to be prompted to the user, providing a clear directional basis for subsequent tactile feedback. If this step is skipped and the electrostatic adsorption poles are directly activated, it becomes impossible to determine which electrostatic adsorption pole should be activated, thus failing to convey directional tactile information to the user. It is evident that this step is the prerequisite and foundation for the entire information prompting method to achieve directional guidance.

[0014] In practical implementation, depending on the information content carried by the interactive command, this embodiment needs to adopt differentiated processing methods to determine the target vector direction. As an example, this embodiment mainly distinguishes between the following two cases and processes them separately.

[0015] In the first scenario, the interaction command itself already contains explicit directional information. In this case, the target application has completed data processing and direction decision-making, and sends the specific direction of travel as structured data within the interaction command to the wearable device. This embodiment directly extracts the directional indication from the interaction command and determines it as the target vector direction. Taking a navigation application as an example, when the navigation application detects that the user has deviated from the preset navigation route, it issues the interaction command "Please correct your direction to the right." This command explicitly contains the "right" directional information, and this embodiment directly determines "right" as the target vector direction. This method has a short response path and fast processing speed, making it suitable for scenarios where the target application has already completed its direction decision.

[0016] Unlike the above scenario, in the second scenario, the interaction command is an activation command, which itself does not contain any directional indication information. In this case, this embodiment recognizes the interaction command as a trigger signal for the direction determination process, rather than the final source of directional information. The purpose of the interaction command is to activate a function or start a process. The specific directional information does not exist when the command is initiated and needs to be determined gradually based on real-time data generated during subsequent operation. Taking a navigation application as an example, when the interaction command is "Start Navigation," this command is only used to start the guidance process of the preset navigation route and does not include any travel direction information. At this time, the device cannot determine which direction to prompt the user. For this type of activation command, this embodiment confirms the entry into the direction prompt state after receiving the command and waits for the target application to provide data information for determining the target vector direction during subsequent operation. Specifically, in the navigation application scenario, this embodiment responds to the interaction command issued by the navigation application, obtains the preset navigation route and the user's current location information. The preset navigation route can be pre-stored in the storage unit inside the wearable interactive device to reduce dependence on real-time communication and reduce power consumption, or it can be provided in real time by the navigation application through wireless communication to support dynamic updates and flexible adjustments of the route. Subsequently, this embodiment determines the positional deviation of the user's current location relative to the preset navigation route based on the user's current location information and the preset navigation route, and determines the target vector direction based on this positional deviation. Specifically, the target vector direction can be a corrected direction guiding the user back to the preset navigation route from the current location, or it can be the next direction guiding the user to continue along the route when the user is already on the preset navigation route. Taking a real-world navigation scenario as an example, when the user is on the preset navigation route and needs to turn right at the next intersection, this embodiment determines "turn right" as the target vector direction based on the direction information of the preset navigation route at the current location; when the user deviates from the preset navigation route, this embodiment determines "corrected direction to return to the preset navigation route" as the target vector direction based on the direction and distance of deviation. As the user's location continues to move and the user's current location information is continuously updated, this embodiment also recalculates the positional deviation and dynamically updates the target vector direction to ensure that the direction information is always synchronized with the current scene.

[0017] In summary, for interactive commands that already include directional indication, this embodiment directly extracts and determines the target vector direction; for activation-type interactive commands that do not contain directional information, they are used as trigger signals, and the target vector direction is gradually determined and continuously updated based on real-time data during the subsequent operation of the target application. Therefore, this step is compatible with interactive commands of different types and information content, and can accurately determine the target vector direction in various application scenarios, providing a reliable directional data foundation for subsequent haptic prompts.

[0018] S102, Based on the target vector direction, determine at least one target electrostatic adsorption pole from all electrostatic adsorption poles, wherein the at least one target electrostatic adsorption pole corresponds to the target vector direction.

[0019] After determining the target vector direction, the directional information needs to be converted into a physical signal that the user can perceive through touch. This means determining which one or more locations on the wearer's contact surface generate an electrostatic adsorption sensation so that the user can perceive the spatial orientation corresponding to the target vector direction. Since directional information is an abstract vector concept, while electrostatic adsorption sensation is a physical feeling occurring at a specific spatial location on the skin surface, it is necessary to establish a correspondence between directional information and the location of the sensation. The significance of this step is that, based on the pre-distributed electrostatic adsorption poles on different locations on the wearer's contact surface, the target vector direction determined in the previous step is mapped to one or more electrostatic adsorption poles corresponding to that direction. This allows the localized electrostatic adsorption sensation generated after energizing the target electrostatic adsorption pole to be perceived by the user at a specific location on the skin surface, thus transforming abstract directional information into a concrete and perceptible spatial location signal.

[0020] In the specific implementation, this embodiment pre-constructs a mapping relationship between multiple vector directions and each electrostatic adsorption pole. This mapping relationship is based on the different orientations of each electrostatic adsorption pole in its distribution location. The purpose is to enable the subsequent power-on process to clearly identify which one or more electrostatic adsorption poles correspond to the target vector direction to be indicated. Since each electrostatic adsorption pole itself only represents its spatial position and does not contain directional semantic information, it is necessary to pre-bind each direction (such as front, back, left, right, etc.) with the corresponding electrostatic adsorption pole in the orientation to form a direction-pole correspondence table that can be quickly looked up. This allows the target vector direction to be directly located to the corresponding electrostatic adsorption pole once it is determined, without the need for temporary direction-to-position calculation. Specifically, the wearable interactive device in this embodiment supports expressing multiple vector directions, including the target vector direction. Each vector direction corresponds to at least one electrostatic adsorption pole, and the electrostatic adsorption tactile sensation corresponding to each vector direction is generated by all the electrostatic adsorption poles corresponding to that vector direction at their respective distribution positions. In other words, when a certain vector direction needs to be indicated, one or more electrostatic adsorption poles corresponding to that direction are activated. The electrostatic adsorption tactile sensation generated by each activated electrostatic adsorption pole at its respective position collectively forms an overall tactile perception pointing in that direction on the user's skin surface. The user can identify the currently indicated direction by feeling the location where the tactile sensation occurs. Taking a navigation scenario as an example, when the target vector direction is "turn left," the mapping relationship binds the "turn left" direction to the electrostatic adsorption pole located on the left side. After this electrostatic adsorption pole is activated, it generates an electrostatic adsorption tactile sensation at its location. The user can know that a left turn is needed by sensing the tactile sensation occurring on the left side. When the target vector direction is "turn right," it is bound to the electrostatic adsorption pole located on the right side. The user can know that a right turn is needed by sensing the tactile sensation occurring on the right side. Through the above mapping relationship, a clear correspondence is established between each vector direction and the corresponding electrostatic adsorption pole, so that after determining the target vector direction, the corresponding target electrostatic adsorption pole can be directly screened based on the mapping relationship, thereby ensuring the efficiency and accuracy of the mapping process.

[0021] To support the physical realization of the above mapping relationship, this embodiment provides corresponding electrostatic adsorption pole arrangement methods for different wearable carrier structural forms, so as to realize directional indication within different spatial coverage areas, thereby ensuring that an accurate correspondence between direction and pole can be established under different wearing forms.

[0022] For example Figure 2As shown, when the wearable body 510 is fitted in a ring shape to the wearing part of the human body, at least some of the electrostatic adsorption poles 520 are arranged at equal angles along the circumference of the contact surface to achieve uniform coverage of the entire surrounding wearing part. Taking the uniform arrangement of eight electrostatic adsorption poles 520 at 45-degree intervals as an example, they can correspond to the eight directions of front, back, left, right, left front, right front, left back, and right back, respectively, thereby covering all directions within a 360-degree circumference of the wearing part, ensuring that navigation commands from any direction can generate accurate tactile prompts at the corresponding circumferential position. Figure 2 The eight electrostatic adsorption poles 520 distributed circumferentially around the central part exemplify the aforementioned ring-shaped arrangement. Each electrostatic adsorption pole 520 is arranged at equal angular intervals along the circumference, with each direction represented by a corresponding electrostatic adsorption pole 520. Users can identify the direction by sensing the circumferential position of the tactile sensation. Taking the "right-front" direction as an example, when a user needs to be prompted to move to the right-front, the electrostatic adsorption pole 520 corresponding to the right-front direction is activated. The user senses a localized electrostatic adsorption sensation at the location of this pole 520, directly identifying the "right-front" direction without relying on visual or auditory aids. In practical applications, to accommodate differences in the size of different user wearing areas and wearing tightness preferences in different usage scenarios, the wearable body 510 is further equipped with a tightness adjustment structure. For example… Figure 7 As shown, the wearable body 510 can achieve three tightness levels (loose, medium, and tight) through adjustable fixing structures such as hook and loop fasteners. Users can select the appropriate level based on the thickness of their wrist, fingers, or neck to ensure the contact surface adheres to the skin with appropriate pressure. Too loose a fit may cause the wearable body 510 to rotate or shift during use, causing the electrostatic adsorption poles 520 to deviate from their preset position. Too tight a fit may affect wearing comfort and is not conducive to long-term use. Based on the above tightness adjustment structure, to accommodate the positional shift of the electrostatic adsorption poles 520 caused by changes in the circumference of the wearable body 510 under different tightness levels, each electrostatic adsorption pole 520 in this embodiment further adopts a modular design. (Continuing...) Figure 7 As shown, each electrostatic adsorption pole 520 is installed as an independent module on the slide rail structure provided on the inner side of the contact surface of the wearable body 510, and can be slidably adjusted along the extension direction of the wearable body 510 on the slide rail. Figure 7The document demonstrates the tension adjustment structure of the hook and loop fasteners and the setting of three positions: loose, medium, and tight. It also shows the modular installation position of the electrostatic adsorption poles 520 on the slide rail. The slide rail is arranged along the extension direction of the wearer, and each electrostatic adsorption pole 520 is embedded as an independent module within the slide rail, allowing it to slide freely to adjust its circumferential position. Users can adjust the installation position of each electrostatic adsorption pole 520 along the slide rail according to the actual tightness setting and personal usage habits, ensuring that each electrostatic adsorption pole 520 is always aligned with its corresponding preset reference position. For example, when the user adjusts the wristband from the loose position to the tight position, the circumference of the wristband shortens, and the relative spacing between the electrostatic adsorption poles 520 needs to be adjusted accordingly to ensure that the electrostatic adsorption poles 520 in all eight directions remain aligned with the correct position. Through this modular sliding adjustment design, different users and different tightness settings can easily adjust to ensure the accurate correspondence between the position of each electrostatic adsorption pole 520 and the user's body coordinate system, thereby ensuring the accuracy and reliability of the directional indication.

[0023] For example Figure 3 As shown, when the wearable device is attached to the body in a planar shape, at least some electrostatic adsorption poles are arranged in an array on the contact surface. This planar array arrangement covers different areas within the contact surface, thus achieving multi-directional tactile differentiation within the planar contact area. Compared to the circumferential omnidirectional coverage achieved by a ring-shaped arrangement, the planar array arrangement can achieve multi-directional differentiation within a limited local contact area. This is suitable for wearing scenarios where the contact surface itself has a certain curvature or a limited area, such as the back of a smartwatch, the earphone, or the virtual reality glasses. Figure 3 The array distribution of electrostatic adsorption poles on the contact surface is indicated by gray, with different positions of the electrostatic adsorption poles in the array corresponding to different orientations within the planar area. When the determined target vector direction is "forward," this embodiment can select one or more electrostatic adsorption poles located in the upper region of the array as target electrostatic adsorption poles based on the mapping relationship; when the target vector direction is "to the right front," one or more electrostatic adsorption poles located in the upper right region of the array are selected as target electrostatic adsorption poles. By activating the electrostatic adsorption poles in the corresponding region, the outline of the activated electrostatic adsorption poles on the contact surface can present an arrow shape corresponding to the target vector direction, allowing the user to directly identify the direction through the shape features perceived by touch. Compared to the dot-like indication of a single electrostatic adsorption pole, the arrow shape formed by the combination of multiple points in the array has stronger directional guidance and recognizability.

[0024] Through the above processing, this embodiment, based on the pre-established mapping relationship between the vector direction and the electrostatic adsorption pole, selects at least one target electrostatic adsorption pole from all electrostatic adsorption poles according to the determined target vector direction, thus completing the mapping process from abstract directional information to the specific physical tactile sensation location.

[0025] S103, energize the target electrostatic adsorption pole to indicate the target vector direction to the user through the electrostatic adsorption tactile sensation generated at the location of the target electrostatic adsorption pole.

[0026] After identifying the target electrostatic adsorption pole, it is necessary to control the current flow to this pole, causing it to generate a perceptible electrostatic adsorption sensation at its location. The significance of this step lies in converting the spatial mapping of directional information from the previous steps into a physical tactile signal. This allows the user to perceive a localized electrostatic adsorption sensation corresponding to the target vector direction at a specific location on the skin surface, thus completing the final transformation from abstract directional information to concrete tactile perception.

[0027] In this embodiment, a driving voltage is applied to the target electrostatic adsorption pole to energize it, thereby generating a localized electrostatic adsorption sensation at the location of the target electrostatic adsorption pole. The principle behind this electrostatic adsorption sensation is as follows: when a driving voltage is applied to the electrostatic adsorption pole, an electrostatic field is formed between the pole and the skin. This field penetrates the layers of structure between the pole and the skin, inducing polarized charges on the skin surface. These polarized charges and the pole generate a Coulomb attraction, which, acting on the skin surface, is perceived by the user as a localized electrostatic adsorption sensation. Since the spatial location of this localized electrostatic adsorption sensation coincides with the orientation of the target electrostatic adsorption pole, and the target pole is selected based on the target vector direction, the user can directly determine the indicated target vector direction by perceiving the specific spatial location of the sensation.

[0028] In practical applications, different users exhibit individual differences in their sensitivity to electrostatic adsorption, and the perceived intensity of the touch also varies for the same user in different usage scenarios. Therefore, this embodiment, when determining to energize the target electrostatic adsorption pole, also adaptively adjusts the energizing parameters based on the intensity level information. Specifically, this embodiment uses pulse width modulation (PWM) to control the energizing of the target electrostatic adsorption pole. Based on the intensity level information, the corresponding driving voltage and switching frequency are determined, and a pulse width modulation signal is output according to the determined driving voltage and switching frequency to achieve precise adjustment of the electrostatic adsorption force intensity. The driving voltage directly determines the magnitude of the electrostatic field strength, thus affecting the magnitude of the induced polarized charge on the skin surface and the magnitude of the adsorption force; the switching frequency affects the continuity and stability of the electrostatic adsorption force. Through the coordinated adjustment of the driving voltage and switching frequency, multi-level tactile intensity adjustment, from gently perceptible to clearly forceful, can be achieved. PWM, by adjusting the duty cycle of the pulse signal to equivalently change the average output voltage, has advantages such as high adjustment accuracy, fast response speed, and low power consumption, meeting the stringent requirements of wearable devices for energy consumption and response time. The intensity level information can be determined through any of the following methods: user-defined settings based on personal preferences, automatic matching based on the target application's usage scenario, or matching based on the user's historical usage habits. For example, when a user is in an outdoor sports scenario requiring high concentration, a higher intensity level can ensure that the tactile feedback is clearly perceived; while in low-interference environments such as sitting or working, a lower intensity level can provide a gentle and unobtrusive feedback experience. By introducing the above intensity level information and adjusting the corresponding pulse width modulation parameters, users can customize the tactile feedback intensity according to their own sensitivity and the current usage scenario, enabling wearable interactive devices to maintain a comfortable and effective tactile feedback effect for different user groups and diverse usage conditions.

[0029] In the aforementioned power-on control process, the fit between the wearable interactive device and the skin directly affects the transmission effect of electrostatic adsorption tactile sensation. Electrostatic adsorption tactile sensation relies on the induction of polarized charges on the skin surface by an electrostatic field. This physical process requires a tight and stable electrical contact interface between the area where the electrostatic adsorption poles are located and the skin. If the wearable interactive device becomes loose or partially detaches from the skin, the distance between the electrostatic adsorption poles and the skin increases, preventing the electric field lines from effectively coupling to the skin surface. This results in a significant decrease or even complete disappearance of the tactile sensation. More seriously, if erroneous tactile sensations are output even when not in contact, users are unable to perceive the expected navigation prompts, easily leading to misjudgments, deviations from the intended direction of travel, and even potential safety risks. Therefore, to ensure the effectiveness of the tactile sensation output, this embodiment introduces a fit evaluation mechanism based on real-time monitoring of electrical parameters. Specifically, this embodiment further detects the contact impedance and capacitance changes between each electrostatic adsorption pole and the wearing part of the body, and quantifies the fit of each area accordingly. In terms of physical characteristics, when the electrode is in close contact with the skin, the contact interface exhibits low impedance and a relatively stable capacitance value. Conversely, if gaps appear at the contact surface or only point contact occurs, the contact impedance will increase significantly, and the capacitance value will fluctuate drastically due to changes in the dielectric environment. By capturing the dynamic characteristics of the above electrical parameters in real time, the adhesion status of each electrostatic adsorption pole area can be accurately identified. Based on the above detection results, this embodiment implements a control strategy of independent detection and selective power-off prohibition. When the adhesion degree of a certain electrostatic adsorption pole area is lower than a preset standard, this embodiment immediately determines that the area is in a non-adhesive state and immediately prohibits power to that specific pole, while other well-adhesive poles are not restricted and are allowed to work normally. The preset standard supports adaptive configuration according to different usage scenarios and wearing locations. Taking a wristband-shaped device as an example, if a user experiences vigorous arm movement during exercise, causing one side of the wristband to temporarily lift and one or more electrostatic adsorption points on that side to detach from the skin, this embodiment will only disable power supply to the non-adhering points on that side. The remaining tightly adhered points will still be able to generate electrostatic adsorption and tactile feedback normally, continuously transmitting directional information to the user. Through this mechanism, this embodiment avoids invalid or misleading tactile output caused by poor local adhesion, while maximizing the protection of the wearable interactive device's limited but reliable directional feedback capability even under non-ideal wearing conditions.

[0030] Furthermore, when first wearing a wearable interactive device, due to differences in the tightness of the fit among different users, or the rotational offset of the device on the limb, the actual contact position of each electrostatic adsorption pole in the human body coordinate system often deviates from the preset reference position. Without correction, even if the target electrostatic adsorption pole is energized strictly according to the preset direction mapping relationship, the tactile orientation perceived by the user will be misaligned with the actual desired navigation direction. This phenomenon is particularly pronounced on ring-shaped wearable interactive devices, directly weakening the reliability of directional guidance. Therefore, this embodiment adds an orientation self-calibration step before performing the power-on operation. Specifically, this embodiment first detects the actual contact position of each electrostatic adsorption pole relative to the wearing part of the body and calculates the angular deviation between it and the preset reference position. Then, it visualizes this deviation data to the user through the display screen of an external terminal, guiding the user to adjust the wearing position or rotate the device. Taking the wristband form as an example, if the wearable interactive device rotates relative to the wrist, causing the electrostatic adsorption pole, which should be facing directly forward of the wrist, to shift to the left front, the external terminal's interface will visually display the current offset direction and angle, prompting the user to rotate the wristband until the electrostatic adsorption pole aligns with the preset forward reference position. Through the above interactive calibration process, this embodiment can quickly achieve precise matching between the electrostatic adsorption pole position and the user's body coordinate system when first worn or when the user perceives an abnormal orientation, thereby fundamentally ensuring the accuracy and reliability of the direction of subsequent power-activated touch sensations.

[0031] Furthermore, when applied to navigation scenarios, this embodiment can, after determining the target vector direction based on the deviation between the user's current location and the preset navigation route, dynamically adjust the driving voltage and switching frequency of the target electrostatic adsorption poles according to the magnitude of this positional deviation. Through this closed-loop adjustment mechanism, the magnitude of the electrostatic adsorption force changes positively correlated with the degree of route deviation: when the user deviates significantly from the predetermined route, the corresponding electrostatic adsorption poles will generate a stronger adsorption force to warn the user of the urgent need to correct their direction; conversely, when the deviation is small, the adsorption force weakens accordingly. In this way, the user can not only obtain directional information ("where to go") through touch, but also perceive the degree of deviation, achieving a leap from single-directional prompts to two-dimensional navigation information with enhanced direction, allowing the user to flexibly adjust their travel strategy accordingly. Further, when the user's location information confirms that they have reached the navigation destination, this embodiment needs to switch to a specific arrival prompt mode to distinguish it from directional guidance during travel, allowing the user to clearly know they have reached their destination without visual assistance. For this purpose, this embodiment sequentially controls the energization of at least two electrostatic adsorption poles according to a preset timing sequence. Figure 4As shown, by controlling the sequential activation of multiple electrostatic adsorption poles along the circumference of the wearing area, a dynamic tactile sequence can be formed, exhibiting changes in both time and space. Specifically, starting from the electrostatic adsorption pole indicated by number "1", the electrostatic adsorption poles indicated by numbers "2", "3", and "4" are activated sequentially according to the direction indicated by the arrows, progressing in this order until a full circumferential scan is completed, ultimately forming a dynamic tactile trajectory that circumferentially sweeps across the skin surface. This circular scanning dynamic sequential tactile sensation differs fundamentally from static point-like tactile sensations that act in a single direction and have a relatively fixed position during movement. Users can clearly distinguish the type of prompt they are receiving simply by the temporal sequence and spatial direction of the tactile sensations, accurately determining whether they are in the directional guidance stage or have reached the prompt state without the need for visual assistance. Through the aforementioned differentiated tactile coding design, the arrival prompts for navigation destinations have clear recognizability at the perception level, effectively avoiding confusion with directional guidance during travel, thereby further enhancing the integrity and ease of use of the navigation experience.

[0032] Through the above processing, this embodiment controls the energization of the target electrostatic adsorption poles. Combining multiple mechanisms such as intensity level adjustment, adhesion state detection and selective energization restriction, orientation calibration, deviation feedback, and endpoint serialization prompts, it transmits the directional information determined in the preceding steps to the user's skin surface in the form of localized electrostatic adsorption tactile sensation, ensuring the effectiveness, safety, and accuracy of the tactile output. The user can obtain the target vector direction information without relying on visual or auditory channels by perceiving the spatial location and intensity characteristics of the tactile sensation.

[0033] It should be noted that the above examples are all specific implementation methods of the device-side embodiments of this application. The correspondence between the electrostatic adsorption pole positions and the target vector directions, as well as the directional prompting methods in navigation scenarios, are only for illustrative purposes and do not constitute a limitation on the technical solutions of this application. In practical applications, users can flexibly customize the electrostatic adsorption pole combinations corresponding to each target vector direction through interaction between the external terminal and the main control module, according to their personal usage habits and specific scenario requirements. For example, a certain direction can be remapped to an electrostatic adsorption pole at any position, or multiple electrostatic adsorption poles can be assigned to the same direction to enhance the tactile intensity. In addition, users can also flexibly configure the mapping relationship between electrostatic adsorption poles and prompting information according to actual needs, so that the type of tactile feedback prompts is not limited to navigation direction guidance, but can be extended to more diverse application scenarios, such as call reminders, message notifications, and schedule reminders. For example, users can sequentially activate multiple electrostatic adsorption poles distributed around the circumference to form a circular dynamic tactile sensation that sweeps across the skin surface in the circumference, as a personalized prompting method for early morning wake-up or timed reminders.

[0034] On the other hand, corresponding Figure 1 In addition to the information prompting method shown, another embodiment of this application also provides a wearable interactive device. Wherein, Figure 5 This is a structural diagram of the wearable interactive device 500, which includes a wearable main body 510, multiple electrostatic adsorption poles 520, and a main control module 530.

[0035] The wearable body 510 has a contact surface that conforms to the part of the human body it is worn on. In this embodiment, the wearable body 510, as the basic structural component of the wearable interactive device, is responsible for fixing the entire interactive system to the user's body. The contact surface serves as the interface between the wearable interactive device and the user's skin, and is a crucial link in whether tactile signals can be effectively transmitted to the user's sensory system. To achieve a good fit and wearing safety, the wearable body 510 can be made of a flexible printed circuit board substrate. The flexible substrate's bendability adapts to deformation caused by limb movements, thereby meeting the comfort requirements for long-term wear. Furthermore, the wearable body 510 can be adapted to various structural forms according to different usage scenarios, such as a ring-shaped structure or a surface structure. A ring-shaped structure can specifically take the form of a smart ring, wristband, or neckband, suitable for scenarios where it surrounds the wearing area; a surface structure can specifically take the form of the back of a smartwatch, the earphone, or the virtual reality glasses, suitable for scenarios where it partially conforms to the wearing area. These various forms can cover the user's needs for different wearing areas.

[0036] Multiple electrostatic adsorption poles 520 are disposed on the contact surface between the wearable body 510 and the wearing part of the human body. When each electrostatic adsorption pole 520 is energized, it generates an electrostatic adsorption tactile sensation. In this embodiment, the electrostatic adsorption poles 520 are not concentrated in a localized area of ​​the contact surface, but are distributed in different orientations on the contact surface. This creates independent tactile feedback points at different locations on the user's skin surface, providing a spatial distribution basis for subsequent directional cues based on orientation encoding. To achieve the above electrostatic adsorption function and provide a basis for detecting the fit, refer to... Figure 6 As shown, a flexible conductive adhesive layer 511 and a biocompatible coating 512 are sequentially stacked on the contact surface of the wearable body 510. The flexible conductive adhesive layer 511 serves as an electrode layer on the contact surface, covering the areas where each electrostatic adsorption pole 520 is located. It establishes an electrical contact interface between the electrostatic adsorption pole 520 and the wearer, ensuring that the electrostatic field can be effectively conducted to the skin surface. The biocompatible coating 512 is disposed on the outer surface of the flexible conductive adhesive layer 511. On the one hand, it physically isolates the flexible conductive adhesive layer 511 from direct contact with the wearer, ensuring the biocompatibility of the wearable interactive device during long-term wear; on the other hand, it allows the electrostatic field to penetrate the coating to generate an electrostatic adsorption sensation on the skin surface. This stacked structure design allows the electrical characteristics of the areas where each electrostatic adsorption pole 520 is located to be independently sensed, providing a physical prerequisite for subsequent adhesion status detection and selective energization control. Specifically, when the area containing a certain electrostatic adsorption pole 520 is in close contact with the skin, the electrical contact interface between the flexible conductive adhesive layer 511 and the skin is intact, the contact impedance is low, and the capacitance value is relatively stable, indicating that the electric field coupling efficiency in this area is good, and the electrostatic adsorption pole 520 can be energized and function normally. However, when a gap is created between the contact surface and the skin due to loose wearing, limb movements, or incorrect wearing position, the intervention of the air gap changes the dielectric environment of the contact interface, the contact impedance increases significantly, and the capacitance value fluctuates significantly, indicating that the electric field coupling efficiency in this area decreases drastically, and even if energized, it is impossible to effectively induce polarized charges on the skin surface. Figure 6The above detection and control mechanism is illustrated using three electrostatic adsorption poles 520 as an example. In the left and right electrostatic adsorption poles 520, there are gaps or only partial contact between the poles and the skin, resulting in an incomplete electrical contact interface. This prevents the flexible conductive adhesive layer 511 from effectively establishing electrical contact between the electrostatic adsorption poles 520 and the skin. Consequently, the contact impedance in these two areas increases significantly, and the capacitance fluctuates. Upon detecting these changes in electrical parameters, this embodiment classifies these two electrostatic adsorption poles 520 as non-adhesive and prohibits them from being energized. Conversely, the electrostatic adsorption pole 520 in the middle position is in close contact with the skin, establishing a complete electrical contact interface between the flexible conductive adhesive layer 511 and the skin. The contact impedance is low, and the capacitance is stable. Upon detecting that the electrical parameters meet preset standards, this embodiment classifies the electrostatic adsorption pole 520 as adhesive and allows it to operate normally. With the synergistic effect of the aforementioned layered structure and bonding detection mechanism, each electrostatic adsorption pole 520 generates a local electrostatic adsorption tactile sensation at its respective location through energization control.

[0037] In practical applications, the wearable interactive device of this embodiment supports the expression of multiple vector directions, including the target vector direction. Each vector direction corresponds to at least one electrostatic adsorption pole 520, and the electrostatic adsorption tactile sensation corresponding to each vector direction is generated jointly by all the electrostatic adsorption poles 520 corresponding to that vector direction at their respective distribution positions. In other words, when a certain vector direction needs to be indicated, one or more electrostatic adsorption poles 520 corresponding to that direction are activated. The electrostatic adsorption tactile sensation generated by each activated electrostatic adsorption pole 520 at its respective position collectively forms an overall tactile perception pointing in that direction on the user's skin surface. The user can identify the currently indicated direction by feeling the location where the tactile sensation occurs. The above-mentioned encoding method of multiple electrostatic adsorption poles 520 jointly representing a single orientation allows the same vector direction to be perceived by the user through the combination of multiple tactile points. Compared with the indication method of a single electrostatic adsorption pole 520, the tactile area formed by the combination of multiple points is larger and the spatial recognition is higher, effectively enhancing the intuitiveness and accuracy of direction recognition.

[0038] Based on the above coding principle, this embodiment provides a corresponding electrostatic adsorption pole 520 layout method for different wearable body 510 structural forms, so as to realize directional prompts within different spatial coverage areas.

[0039] For example Figure 2As shown, when the wearable body 510 is fitted in a ring shape to the wearing part of the human body, at least some of the electrostatic adsorption poles 520 are arranged at equal angles along the circumference of the contact surface to achieve uniform coverage of the entire surrounding wearing part. For example, eight electrostatic adsorption poles 520 are evenly arranged at 45-degree intervals, corresponding to the eight directions of front, back, left, right, left front, right front, left back, and right back, respectively, thereby covering all directions within a 360-degree circumference of the wearing part, ensuring that navigation commands from any direction can generate accurate tactile feedback at the corresponding circumferential position. Figure 2 The eight electrostatic adsorption poles 520 distributed circumferentially around the central part exemplify the aforementioned ring-shaped arrangement. Each electrostatic adsorption pole 520 is arranged at equal angular intervals along the circumference, with each direction represented by a corresponding electrostatic adsorption pole 520. Users can identify the direction by sensing the circumferential position of the tactile sensation. Taking the "right-front" direction as an example, when a user needs to be prompted to move to the right front, the electrostatic adsorption pole 520 corresponding to the right-front direction is activated. The user senses a localized electrostatic adsorption sensation at the location of this electrostatic adsorption pole 520, directly identifying the "right-front" direction without relying on visual or auditory aids. In practical applications, to accommodate differences in the size of different user wearing areas and wearing tightness preferences in different usage scenarios, the ring-shaped wearable body 510 is further equipped with a tightness adjustment structure. For example... Figure 7As shown, the annular wearable body 510 can achieve three tightness levels (loose, medium, and tight) through adjustable fixing structures such as hook and loop fasteners. Users can select the appropriate level according to the thickness of their wrists, fingers, or necks to ensure that the contact surface adheres to the skin surface with appropriate pressure. Too loose a fit may cause the wearable body 510 to rotate or shift during use, causing the electrostatic adsorption poles 520 to deviate from their preset positions; too tight a fit may affect wearing comfort and is not conducive to long-term use. Based on the above tightness adjustment structure, to accommodate the positional shift of the electrostatic adsorption poles 520 caused by changes in the circumference of the wearable body 510 under different tightness levels, each electrostatic adsorption pole 520 in this embodiment further adopts a modular design. Each electrostatic adsorption point 520 is installed as an independent module on a slide rail structure located inside the contact surface of the wearable body 510. It can slide and adjust along the extension direction of the wearable body 510. Users can adjust the installation position of each electrostatic adsorption point 520 along the slide rail according to their actual wearing tightness and personal usage habits, ensuring that each electrostatic adsorption point 520 is always aligned with its corresponding preset reference position. For example, when the user adjusts the wristband from a loose to a tight position, the circumference of the wristband shortens, and the relative spacing between the electrostatic adsorption points 520 needs to be adjusted accordingly to ensure that the electrostatic adsorption points 520 in all eight directions remain aligned with the correct position. Through this modular sliding adjustment design, different users and different tightness levels can easily adjust the position of each electrostatic adsorption point 520 to ensure accurate correspondence with the user's body coordinate system, thereby ensuring the accuracy and reliability of the directional indication.

[0040] For example Figure 3 As shown, when the wearable body 510 is attached to the wearer's body in a planar shape, at least some of the electrostatic adsorption poles 520 are arranged in an array on the contact surface. This planar array arrangement covers different areas within the contact surface, thereby achieving multi-directional tactile differentiation within the planar contact area. Compared to the circumferential omnidirectional coverage achieved by the aforementioned ring-shaped arrangement, the planar array arrangement can achieve multi-directional differentiation within a limited local contact area. This is suitable for wearing scenarios where the contact surface itself has a certain curvature or a limited area, such as the back contact surface of a smartwatch, the contact surface of an earphone, or the contact surface of virtual reality glasses. In the above scenarios, the contact surface of the wearable body 510 only covers a local area of ​​the wearer's body, making it impossible to arrange electrodes circumferentially. However, the array layout can encode directional information within a limited two-dimensional plane through the spatial differences in the positions of the electrostatic adsorption poles 520. Figure 3The array distribution of each electrostatic adsorption pole 520 on the contact surface is schematically marked in gray, and two directional indication scenarios are illustrated: When the target vector direction is "forward", one or more electrostatic adsorption poles 520 located in the upper region of the array are activated. These activated electrostatic adsorption poles 520 together form an arrow shape pointing directly upward. The user can identify the "forward" directional indication by perceiving the arrow-shaped tactile distribution in this area. When the target vector direction is "to the right and forward", one or more electrostatic adsorption poles 520 located in the upper right region of the array are activated. These activated electrostatic adsorption poles 520 together form a diagonal arrow shape pointing to the upper right. The user can identify the "to the right and forward" directional indication by perceiving this diagonal arrow-shaped tactile distribution. In other words, by activating multiple electrostatic adsorption poles 520 in different regions and arrangements in the array, the collective outline of the activated electrostatic adsorption poles 520 on the contact surface can present an arrow pattern corresponding to the target vector direction, allowing the user to directly identify the direction through the shape features perceived by touch. Compared to the dot-like indication of a single electrostatic adsorption pole 520, the arrow shape formed by multiple points in the array provides stronger directional guidance and recognizability. Electrostatic adsorption poles 520 at different locations correspond to different orientations within the planar area. By activating the corresponding electrostatic adsorption poles 520 and making them display the corresponding arrow shape, richer and more intuitive directional information can be expressed. Therefore, whether in a circumferentially omnidirectional coverage scenario with a ring structure or a localized coverage scenario with a planar structure, users can directly obtain directional guidance by perceiving the spatial location and distribution shape of the touch sensation.

[0041] Main control module 530, used for execution Figure 1The information prompting method involves the main control module 530 first determining the target vector direction based on interactive commands. This target vector direction represents the directional information to be prompted to the user, such as left turn, right turn, or straight-ahead direction indicators in a navigation scenario. After determining the target vector direction, the main control module 530 identifies at least one target electrostatic adsorption pole 520 corresponding to the target vector direction from all electrostatic adsorption poles 520. Since each electrostatic adsorption pole 520 is pre-distributed at different locations on the contact surface, and each location corresponds to a specific direction, the main control module 530 only needs to quickly filter out one or more electrostatic adsorption poles 520 matching the target direction as target electrostatic adsorption poles 520 based on the correspondence between the target vector direction and the locations of each electrostatic adsorption pole 520. Subsequently, the main control module 530 controls the target electrostatic adsorption pole 520 to be energized, causing the target electrostatic adsorption pole 520 to generate a local electrostatic adsorption tactile sensation at its location. The target electrostatic adsorption pole 520 is located in the same direction as the target vector. Users can directly determine the indicated direction by sensing the specific location of the touch on their skin; the location of the touch indicates the direction in which movement or adjustment is needed. Throughout the interaction, users do not need to look at the screen or listen to voice prompts; they can obtain directional information solely through localized tactile sensation on their skin, achieving completely sensory-free directional guidance without the need for visual or auditory input. It should be noted that when the interaction command is an activation command and the target vector direction is not yet determined, the main control module 530, after confirming the need to enter the directional prompt state, does not immediately execute the screening and power-on control of the target electrostatic adsorption pole 520. Instead, it waits for the target application to provide data information to determine the target vector direction during subsequent operation. Only after the target vector direction is determined does it execute the subsequent screening and power-on operation of the electrostatic adsorption pole 520, thereby ensuring the accuracy of the directional prompt.

[0042] It should be noted that the main control module 530 in this embodiment is controlled by... Figure 1 The method shown achieves its function, and therefore has the same Figure 1 The technical effects of the information prompting method shown are not elaborated here.
