Description

Technical Field

[0001] The present disclosure relates to the technical field of device interaction and navigation, and particularly to a navigation method, a wearable device, a computer program product, and a readable storage medium. Background Art

[0002] Currently, the mainstream navigation methods mainly rely on the indication of the mobile phone navigation interface or navigation voice prompts.

[0003] However, these two current navigation methods have many limitations. For example, in a noisy environment, such as a bustling market, a construction site, or a busy street, the navigation voice is easily drowned out by background noise, making it difficult for users to hear clearly. For people with hearing impairments or hearing disabilities, the navigation voice is even ineffective.

[0004] For another example, in scenarios that require high concentration, such as running or cycling, frequently checking the navigation interface on the mobile phone screen will distract attention and pose a safety hazard. Summary of the Invention

[0005] The present disclosure provides a navigation method, a wearable device, a computer program product, and a readable storage medium, which can prompt the navigation direction by controlling a signal generating unit array in the wearable device to emit physical stimulation signals according to a control strategy, thereby avoiding the limitations of the current navigation methods.

[0006] In a first aspect, the present application provides a navigation method, which is applied to a wearable device provided with a signal generating unit array; the method includes: in response to the user reaching a path node in the navigation path, determining the navigation direction of the path node; based on the navigation direction of the path node, determining a first control strategy corresponding to the navigation direction; the first control strategy is used to determine a first target signal generating unit in the signal generating unit array and the order in which each first target signal generating unit emits physical stimulation signals; the first target signal generating unit is used to dynamically form a tactile perception trajectory corresponding to the navigation direction during the process of sequentially emitting physical stimulation signals in the order determined by the first control strategy; based on the first control strategy, controlling each first target signal generating unit to sequentially emit physical stimulation signals to indicate the navigation direction.

[0007] In a second aspect, the present disclosure provides a navigation device, which is applied to a wearable device including a signal generating unit array, and the navigation device includes each functional module for the method described in the first aspect above.

[0008] In a third aspect, the present disclosure provides a wearable device, including a signal generating unit array, for implementing the method described in the first aspect above.

[0009] Fourthly, the present disclosure provides a computer program product, including: computer instructions; when the computer instructions run in a wearable device including a signal generation unit array, the wearable device implements the method described in the first aspect above.

[0010] Fifthly, the present disclosure provides a readable storage medium, including: software instructions; when the software instructions run in a wearable device including a signal generation unit array, the wearable device implements the method described in the first aspect above.

[0011] It should be understood that in outdoor scenarios such as cycling or running, users need to constantly pay attention to road conditions. Traditional visual navigation methods are prone to distraction, and the voice prompts of auditory navigation methods may be unclear due to environmental noise, increasing the risk of accidents and posing safety hazards.

[0012] In the navigation method provided by the present disclosure, the wearable device can, in response to the user reaching a path node in the navigation path, determine the navigation direction of the path node, and then, based on the navigation direction of the path node, determine a first control strategy corresponding to the navigation direction. Based on the first control strategy, control each first target signal generation unit to sequentially emit physical stimulation signals to dynamically form a tactile perception trajectory corresponding to the navigation direction to indicate the navigation direction. In this way, by emitting physical stimulation signals through the signal generation unit array in the wearable device to form a tactile perception trajectory to indicate the navigation direction, the user does not need to frequently check the mobile phone screen and listen to voices, and can concentrate more attention on the road conditions ahead, greatly improving the travel safety factor.

[0013] In addition, the navigation method provided by the embodiments of the present disclosure can provide a convenient and efficient interaction through physical stimulation signals in contact with the skin. Without manual operation of the mobile phone, navigation instructions can be received in real time, especially suitable for scenarios where both hands are busy, such as when driving a car or carrying items. This convenient interaction method saves the user's operation time, makes the navigation process more smooth and natural, and improves the overall travel efficiency.

[0014] Finally, the navigation method provided by the embodiments of the present disclosure can provide a new travel navigation method for special groups such as visually impaired people, hearing impaired people, or the elderly when traveling. Through physical stimulation signals, special groups can clearly understand the traveling direction and effectively solve the travel problems of special groups. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Currently, the mainstream navigation methods mainly rely on the indication of the mobile phone navigation interface or the navigation voice prompt.

[0033] However, there are many limitations in these two current navigation methods.

[0034] For example, in a noisy environment such as a bustling market, a construction site, or a busy street, the navigation voice is easily drowned out by background noise, making it difficult for users to hear clearly. For people with hearing impairments or disabilities, the navigation voice is even more ineffective.

[0035] For another example, in scenarios that require high concentration, such as running or cycling, frequently checking the navigation interface on the mobile phone screen will distract attention and pose a safety hazard.

[0036] Based on this, the embodiments of the present disclosure provide a navigation method, a wearable device, a computer program product, and a readable storage medium, which can prompt the navigation direction by controlling the signal generation unit array in the wearable device to emit physical stimulation signals according to a control strategy, thereby avoiding the limitations of current navigation methods.

[0037] The following is an introduction with reference to the accompanying drawings.

[0038] Figure 1 FIG. is a schematic diagram of the composition of the navigation system provided by the embodiments of the present disclosure. As Figure 1 shown, the navigation system includes: a navigation device 100 and a wearable device 200. There is a communication connection between the navigation device 100 and the wearable device 200 ( Figure 1 illustrated by Bluetooth connection as an example).

[0039] The navigation device 100 can be a terminal device with navigation functions such as a mobile phone, a car navigation device, a handheld Global Positioning System (GPS) navigator, etc., Figure 1 illustrated by taking the navigation device 100 as a mobile phone as an example.

[0040] The navigation device 100 can be used to create a navigation path and detect the user's current position, and determine whether the user has reached a path node in the navigation path.

[0041] In some embodiments, the navigation device 100 can also be used to determine the navigation direction of the path node based on the user reaching the path node in the navigation path, and generate a navigation instruction based on the navigation direction of the path node. The navigation instruction includes the aforementioned navigation direction, and sends the navigation instruction to the wearable device 200 to prompt the navigation direction.

[0042] The wearable device 200 can be an in-ear headphone, an ear-hanging headphone, a watch, a smart bracelet, a wristband, an insole, clothing, a handbag, a lipstick, etc., which can be in direct contact with the human skin and include a signal generation unit array and are wearable items, Figure 1 illustrated by taking the wearable device 200 as an in-ear headphone and a smart bracelet as an example.

[0043] In some embodiments, as Figure 1As shown in the figure, an electrode feed point and a resistance feed point may be included in the wearable device.

[0044] As an example, Figure 2 FIG. is a schematic diagram of a simple circuit of the electrode feed point provided by an embodiment of the present disclosure. As Figure 2 shown, the simple circuit may include a power supply, a switch, a control chip, and an electrode feed point. The electrode feed point may specifically be an electrode array, and the electrode array includes a plurality of discharge electrodes distributed in an array.

[0045] As an example, Figure 3 FIG. is a schematic diagram of a simple circuit of the resistance feed point provided by an embodiment of the present disclosure. As Figure 3 shown, the simple circuit may include a power supply, a switch, a control chip, and a resistance feed point. The resistance feed point may specifically be a single heating resistor.

[0046] It should be noted that, in the above Figure 3 an example is given where the resistance feed point is a single heating resistor. In some embodiments, the resistance feed point may also be a resistance array similar to the structure shown in Figure 2 FIG., and the resistance array includes a plurality of heating resistors distributed in an array. The embodiments of the present disclosure do not limit this. When the resistance feed point is a resistance array, the resistance array and the foregoing electrode array may also be understood as a signal generating unit array.

[0047] It should be noted that, in order to ensure user safety, the current intensity of the discharge electrode and the temperature rise range of the heating resistor are both controlled within a safe range. The human body's perception range of microcurrents is between dozens of microamperes and hundreds of microamperes. Therefore, in the embodiments of the present disclosure, the microcurrent emitted by the discharge electrode may be set between 10 - 100 microamperes, which is lower than the current intensity that may cause harm to the human body, and the current is output in the form of pulses to further reduce the discomfort caused by long-term stimulation, which can not only ensure the user's clear perception but also not cause damage to the human body's nerves, muscles and other tissues.

[0048] The appropriate parameter temperature change of the temperature rise range of the heating resistor is also safe. The human body has a perceived temperature and the temperature range without being harmed is within 1 - 3°C deviation from the normal body temperature range. This range can not only ensure that the user perceives the temperature change but also does not cause discomfort. When the temperature rises, the maximum temperature generally does not exceed 3°C above the normal human body temperature (36.5°C), that is, does not exceed 39.5°C, to avoid the risk of scalding.

[0049] The wearable device 200 may be used to control the signal generating unit array to emit physical stimulation signals to indicate the navigation direction in response to the user reaching a path node in the navigation path. The specific process may refer to that described in the following method embodiments and will not be elaborated here.

[0050] In some embodiments, as described above, the navigation device 100 may send navigation instructions to the wearable device 200. The wearable device 200 may, in response to the navigation instructions, emit physical stimulation signals through the signal generating unit array to prompt the navigation direction.

[0051] In some embodiments, the wearable device 200 may also have a navigation function, that is, the wearable device 200 may create a navigation path and detect the user's current position, determine whether the user has reached a path node in the navigation path, and in response to the user reaching a path node in the navigation path, emit physical stimulation signals through the signal generating unit array to prompt the navigation direction.

[0052] Based on the above Figures 1 to 3 understanding, taking the navigation device 100 as a mobile phone and the wearable device 200 as an earphone as an example, Figure 4 is an interaction schematic diagram of the mobile phone and the earphone provided by the embodiments of the present disclosure. As Figure 4 shown, the mobile phone hardware navigation issues an instruction, and the mobile phone Bluetooth module in the mobile phone and the earphone Bluetooth module in the earphone can implement information transmission between the mobile phone and the wearable device (or referred to as the wearable device, that is, Figure 4 the earphone herein) through Bluetooth. The earphone Bluetooth receives the information and decodes it, analyzes and extracts the navigation instruction data therein, then converts the digital signal into an electrical signal that the earphone can process, and sends it to the earphone control chip. The earphone control chip sends a microcurrent control instruction, issues an instruction to control the current feeding points of the 9-square grid to be triggered sequentially from the lower left to the upper right and issues a microcurrent. If the user feels a microcurrent interaction feedback of turning right through the wearable device, the navigation information is obtained. The earphone control chip sends a temperature instruction, issues an instruction to control the resistance feeding points of the temperature interaction to increase the temperature, and increases the temperature. If the user feels a temperature increase interaction feedback through the wearable device, the information of prompting speeding is obtained.

[0053] It should be noted that the above description takes the navigation device 100 and the wearable device 200 as independent devices respectively as an example. In some embodiments, the above navigation device 100 and the wearable device 200 may also be combined into one body. That is, the navigation device 100 or its corresponding function, and the wearable device 200 or its corresponding function may be integrated in one device. For example, a wearable device with a navigation function. The embodiments of the present disclosure do not limit this.

[0054] The execution subject of the navigation method provided by the embodiments of the present disclosure is a wearable device (such as the above-mentioned wearable device 200), or it can also be a processor in the aforementioned wearable device (such as a central processing unit (CPU)); alternatively, it can also be a control chip in the aforementioned wearable device; or it can also be an application (APP) installed in the aforementioned wearable device; or it can also be a functional module for executing the navigation method in the aforementioned wearable device, etc. The embodiments of the present disclosure do not limit this.

[0055] For simplicity of description, hereinafter, the execution subject of the navigation method provided by the embodiments of the present disclosure is taken as a wearable device as an example for introduction.

[0056] The navigation method provided by the embodiments of the present disclosure is introduced below in conjunction with the accompanying drawings.

[0057] Figure 5 It is a schematic flowchart of the navigation method provided by the embodiments of the present disclosure. As Figure 5 shown, the method includes the following steps:

[0058] S101. In response to the user arriving at a path node in the navigation path, determine the navigation direction of the path node.

[0059] As an example, as described above, the wearable device can be communicatively connected to a navigation device. In this case, the wearable device can specifically receive a navigation instruction sent by the navigation device to determine the navigation direction of the path node.

[0060] Among them, the navigation instruction includes a navigation direction, and the navigation instruction is sent when the navigation device detects that the user arrives at the path node.

[0061] As another example, as described above, the wearable device can also have a navigation function. In this case, the wearable device can create a navigation path and detect the user's current position. Based on the navigation path and the user's current position, determine whether the user arrives at a path node in the navigation path, and in response to the user arriving at a path node in the navigation path, determine the navigation direction of the path node based on the navigation path.

[0062] S102. Based on the navigation direction of the path node, determine a first control strategy corresponding to the navigation direction.

[0063] Among them, the first control strategy is used to determine the first target signal generating unit in the signal generating unit array and the order in which each first target signal generating unit emits physical stimulation signals. The first target signal generating unit is used to dynamically form a tactile perception trajectory corresponding to the navigation direction during the process of sequentially emitting physical stimulation signals in the order determined by the first control strategy.

[0064] In a possible implementation, a wearable device may preset a correspondence between different navigation directions and a first control strategy. In this case, the wearable device may specifically query the foregoing correspondence based on the navigation direction of a path node to determine the first control strategy corresponding to the navigation direction.

[0065] Exemplarily, Figure 6 FIG. is a schematic diagram of a tactile perception trajectory provided by an embodiment of the present disclosure. As Figure 6 shown, taking a 9-grid array of 9 signal generating units × 9 signal generating units in the signal generating unit array as an example, when the navigation direction is a right turn, the corresponding first control strategy may be to control three target signal generating units on the diagonal line from the lower left to the upper right to sequentially emit physical stimulation signals. When the navigation direction is a left turn, the corresponding first control strategy may be to control three target signal generating units on the diagonal line from the lower right to the upper left to sequentially emit physical stimulation signals. When the navigation direction is straight ahead, the corresponding first control strategy may be to control three target signal generating units in the middle column from bottom to top to sequentially emit physical stimulation signals. When the navigation direction is straight backward, the corresponding first control strategy may be to control three target signal generating units in the middle column from top to bottom to sequentially emit physical stimulation signals. When the navigation direction is a right turn and U-turn, the corresponding first control strategy may be to sequentially control the first signal generating unit in the third row, the first signal generating unit in the second row, the second signal generating unit in the first row, the third signal generating unit in the second row, and the third signal generating unit in the third row to sequentially emit physical stimulation signals. When the navigation direction is a left turn and U-turn, the corresponding first control strategy may be to sequentially control the third signal generating unit in the third row, the third signal generating unit in the second row, the second signal generating unit in the first row, the first signal generating unit in the second row, and the first signal generating unit in the third row to sequentially emit physical stimulation signals.

[0066] S103. Based on the first control strategy, control each first target signal generating unit to sequentially emit physical stimulation signals to indicate the navigation direction.

[0067] As an example, the signal generating units in the signal generating unit array as described above may specifically include discharge electrodes and / or heating resistors. In this case, the physical stimulation signals include electrical signals and / or temperature signals.

[0068] It should be understood that in outdoor scenarios such as cycling or running, users need to constantly pay attention to road conditions. However, traditional visual navigation methods are prone to distraction, and the voice prompts of auditory navigation methods may be inaudible due to environmental noise, increasing the risk of accidents and posing safety hazards.

[0069] In the navigation method provided by the embodiments of the present disclosure, the wearable device can determine the navigation direction of the path node in response to the user reaching the path node in the navigation path, and then determine the first control strategy corresponding to the navigation direction based on the navigation direction of the path node. Based on the first control strategy, control each first target signal generating unit to sequentially emit physical stimulation signals to dynamically form a tactile perception trajectory corresponding to the navigation direction to indicate the navigation direction. In this way, by emitting physical stimulation signals through the signal generating unit array in the wearable device to form a tactile perception trajectory to indicate the navigation direction, the user does not need to frequently check the mobile phone screen and listen to the voice, and can focus more attention on the road conditions ahead, greatly improving the travel safety factor.

[0070] In addition, the navigation method provided by the embodiments of the present disclosure can provide a convenient and efficient interaction through physical stimulation signals in contact with the skin. Without manually operating the mobile phone, the user can receive navigation instructions in real time, especially suitable for scenarios where both hands are busy, such as driving a car or carrying items. This convenient interaction method saves the user's operation time, makes the navigation process more smooth and natural, and improves the overall travel efficiency.

[0071] Finally, the navigation method provided by the embodiments of the present disclosure can provide a new travel navigation method for special groups such as visually impaired people, hearing impaired people, or the elderly when traveling. Through physical stimulation signals, special groups can clearly understand the traveling direction and effectively solve the travel problems of special groups.

[0072] In some possible embodiments, after starting navigation and setting the destination, the wearable device can also emit physical stimulation signals to prompt the user of the location type of the destination (such as home, company, or school, etc.).

[0073] In this case, the method may further include the following steps:

[0074] Step 1a, determine the location type of the destination of the navigation path.

[0075] As an example, the user can first configure the location types of different locations on the navigation device. When the navigation path is created, the navigation device can determine the location type of the destination based on the pre-configured location types of different locations and the destination of the currently created navigation path.

[0076] Exemplarily, Figure 7 is a schematic diagram of the tactile perception pattern setting provided by the embodiments of the present disclosure. As Figure 7As shown, for the destination location with the location type of home, the user can set the symbol for going home as a diamond. For the destination location with the location type of company, the user can set the symbol for going to work as a cross. For the destination location with the location type of frequently visited supermarket, the user can set the symbol for the frequently visited supermarket as a cross. For the destination location with the location type of primary school, the user can set the symbol for the primary school as a square.

[0077] Step 2a: Based on the location type of the destination location, determine the second control strategy corresponding to the location type of the destination location.

[0078] Among them, the second control strategy is used to determine the second target signal generation unit in the signal generation unit array and the order of the physical stimulation signals emitted by each second target signal generation unit. The second target signal generation unit is used to form a tactile perception pattern corresponding to the location type of the destination location of the navigation path during the emission of the physical stimulation signals.

[0079] In a possible implementation, the wearable device may preset the corresponding relationship between different location types and the second control strategy. The wearable device can search for the foregoing corresponding relationship based on the location type of the destination location to determine the second control strategy corresponding to the location type of the destination location.

[0080] As an example, the order in which the second control strategy controls the second target signal generation unit to emit physical stimulation signals can be in a clockwise order, a counterclockwise order, from left to right, from right to left, from top to bottom, from bottom to top, or simultaneously emit, etc. The specific order in which the second control strategy controls the second target signal generation unit to emit physical stimulation signals is not limited in the embodiments of the present disclosure.

[0081] Exemplarily, Figure 8 is a schematic diagram of triggering a tactile perception pattern provided by the embodiments of the present disclosure. As Figure 8 shown, as described above Figure 7Taking the set tactile perception patterns as an example, after the user starts navigating home to a destination with the location type set as home, the wearable device can control the signal generation unit array to emit stimulation signals according to the second control strategy to generate a diamond-shaped tactile perception pattern to prompt the user that the location type of the current destination is home. After the user starts navigating to work to a destination with the location type set as company, the wearable device can control the signal generation unit array to emit stimulation signals according to the second control strategy to generate a cross-shaped tactile perception pattern to prompt the user that the location type of the current destination is company. After the user starts navigating to a frequently visited supermarket to a destination with the location type set as frequently visited supermarket, the wearable device can control the signal generation unit array to emit stimulation signals according to the second control strategy to generate a cross-shaped tactile perception pattern to prompt the user that the location type of the current destination is frequently visited supermarket. After the user starts navigating to school or picking up / dropping off students to a destination with the location type set as primary school, the wearable device can control the signal generation unit array to emit stimulation signals according to the second control strategy to generate a square tactile perception pattern to prompt the user that the location type of the current destination is primary school.

[0082] Step 3a: Based on the second control strategy, control each second target signal generation unit to emit physical stimulation signals to prompt the location type of the destination.

[0083] In some possible embodiments, when the user is approaching the destination of the historical navigation path, even if no navigation is performed, the wearable device can also emit physical stimulation signals to prompt the user that they are approaching the destination of the historical navigation path. In this case, the method may further include the following steps:

[0084] Step 1b: Determine the distance between the user and the destination of the historical navigation path.

[0085] As an example, as described above, the wearable device can be communicatively connected to a navigation device. In this case, the distance between the user and the destination of the historical navigation path can be sensed and detected by the navigation device and sent to the wearable device.

[0086] As another example, as described above, the wearable device can also have a navigation function. In this case, the distance between the user and the destination of the historical navigation path can be directly sensed and detected by the wearable device.

[0087] Step 2b: When the distance is less than a preset distance threshold, determine the third control strategy corresponding to the location type of the destination of the historical navigation path.

[0088] Among them, the preset distance threshold can be preset in the wearable device. For example, the preset distance threshold can be set to 1000 meters, 800 meters, 500 meters, or 100 meters, etc. The embodiments of the present disclosure do not limit the specific value of the preset distance threshold. The third control strategy is used to determine the third target signal generating units in the signal generating unit array and the order in which each third target signal generating unit emits physical stimulation signals. The third target signal generating unit is used to form a tactile perception pattern corresponding to the location type of the destination of the historical navigation path during the process of emitting physical stimulation signals. The tactile perception pattern of the third control strategy can specifically refer to that described in the above second control strategy and will not be elaborated here.

[0089] Step 3b: Based on the third control strategy, control each third target signal generating unit to emit physical stimulation signals to prompt the location type of the nearby destination of the historical navigation path.

[0090] In some embodiments, for the above second control strategy and / or third control strategy for generating the tactile perception pattern, the wearable device can also adjust the frequency and / or intensity of the physical stimulation signals according to the distance from the destination. In this case, the method can further include the following steps:

[0091] Step 1c: Based on the distance between the user and the destination, adjust the frequency and / or intensity of the emitted physical stimulation signals.

[0092] Among them, the frequency of the physical stimulation signals emitted by the wearable device is negatively correlated with the distance between the user and the destination. That is, the closer the distance between the user and the destination, the higher the frequency of the physical stimulation signals emitted by the wearable device; the farther the distance between the user and the destination, the lower the frequency of the physical stimulation signals emitted by the wearable device. The intensity of the physical stimulation signals emitted by the wearable device is negatively correlated with the distance between the user and the destination. That is, the closer the distance between the user and the destination, the greater the intensity of the physical stimulation signals emitted by the wearable device; the farther the distance between the user and the destination, the smaller the intensity of the physical stimulation signals emitted by the wearable device.

[0093] It should be noted that during the navigation process, in order to avoid confusion of the physical stimulation signals emitted by the first target signal generating unit and the second target signal generating unit, the range for the first control strategy to select the first target signal generating unit can be different from the range for the second control strategy to select the second target signal generating unit. For example, the range for the first control strategy to select the first target signal generating unit can be within a 9-grid range in the signal generating unit array, and the range for the second control strategy to select the second target signal generating unit can be within a 25-grid range in the signal generating unit array.

[0094] In some possible embodiments, the wearable device may also emit a physical stimulation signal to prompt the user that they have deviated from the navigation path. In this case, the method may further include the following steps:

[0095] Step 1d: In response to the user deviating from the navigation path, control all or part of the signal generating units in the signal generating unit array to emit a physical stimulation signal to prompt the user that they have deviated from the navigation path.

[0096] For example, the wearable device may obtain the degree of deviation or the distance between the user and the navigation path, and determine whether the user has deviated from the navigation path based on the degree of deviation or the distance.

[0097] As an example, as described above, the wearable device may be communicatively connected to a navigation device. In this case, the degree of deviation or the distance between the user and the navigation path may be sensed and detected by the navigation device and sent to the wearable device.

[0098] As another example, as described above, the wearable device may also have a navigation function. In this case, the degree of deviation or the distance between the user and the navigation path may also be directly sensed and detected by the wearable device.

[0099] As another example, the navigation device may obtain the degree of deviation or the distance between the user and the navigation path, determine whether the user has deviated from the navigation path based on the degree of deviation or the distance, and send an instruction to the wearable device to indicate that the user has deviated from the navigation path when the user has deviated from the navigation path.

[0100] Exemplarily, as described above, the signal generating units in the signal generating unit array may specifically be heating resistors, and the wearable device may control the heating resistors to increase in temperature and emit a temperature signal to prompt the user that they have deviated from the navigation path in response to the user deviating from the navigation path.

[0101] In some embodiments, the wearable device may also control the signal generating units in the signal generating unit array to stop emitting the physical stimulation signal that prompts the user that they have deviated from the navigation path in response to the user returning to the navigation path.

[0102] In some possible embodiments, the wearable device may also emit a physical stimulation signal to prompt the user that they are speeding. In this case, the method may further include the following steps:

[0103] Step 1e: In response to the user's speed exceeding the speed threshold, control all or part of the signal generating units in the signal generating unit array to emit a physical stimulation signal to prompt the user that they are speeding.

[0104] Among them, the speed threshold can be a fixed threshold, or it can also be different thresholds set corresponding to different navigation modes. For example, the speed threshold can be the upper limit of the speed limit of the road through which the navigation path passes. Or, for electric vehicle navigation, the speed threshold can be set to 25 km / h or 30 km / h, etc.; for car navigation, the speed threshold can be set to the upper limit of the road speed limit. The specific value of the speed threshold is not limited in the embodiments of the present disclosure.

[0105] For example, the wearable device can obtain the user's speed and determine whether it exceeds the speed threshold according to the user's speed.

[0106] As an example, as described above, the wearable device can be communicatively connected to the navigation device. In this case, the user's speed can be sensed and detected by the navigation device and sent to the wearable device.

[0107] As another example, as described above, the wearable device can also have a navigation function. In this case, the user's speed can also be directly sensed and detected by the wearable device.

[0108] For another example, the navigation device can obtain the user's speed, determine whether the user is speeding according to the user's speed, and send an instruction to the wearable device to indicate that the user is speeding when the user is speeding.

[0109] Exemplarily, as described above, the signal generating unit in the signal generating unit array can specifically be a heating resistor. The wearable device can control the heating resistor to heat up and emit a temperature signal to prompt the user that they are speeding in response to the user's speed exceeding the speed threshold.

[0110] In some embodiments, the wearable device can also control the signal generating unit of the signal generating unit array to stop emitting the physical stimulation signal that prompts the user of speeding in response to the user's speed dropping below the speed threshold.

[0111] In some possible embodiments, before assisting navigation through the signal generating unit array, due to wearing habits and angle problems, the direction of the signal generating unit array also needs to be calibrated, similar to entering fingerprint recognition information for a new device, and no further calibration is required when the subsequent wearing habits are fixed.

[0112] Exemplarily, Figure 9 is a calibration schematic diagram provided for the embodiments of the present disclosure. As Figure 9As shown, taking a smart bracelet as an example of a wearable device, when the signal generating unit array in the smart bracelet is placed correctly on the arm, it can correctly generate a tactile perception pattern. When the signal generating unit array is tilted left or right on the arm, it cannot correctly generate a tactile perception pattern. Taking in-ear headphones as an example of a wearable device, when the signal generating unit array in the in-ear headphones is placed correctly in the ear, it can correctly generate a tactile perception pattern. When the signal generating unit array is tilted left or right in the ear, it cannot correctly generate a tactile perception pattern.

[0113] In some possible embodiments, before the signal generating unit array is controlled to emit a physical stimulation signal, the wearable device may also obtain the user's authorization for navigation assisted by the physical stimulation signal. For example, the navigation device may display an introduction interface for the navigation function assisted by the physical stimulation signal, and the introduction interface may include a user authorization option. When the navigation device receives the user's selection operation on the authorization option, it may send an instruction to the wearable device to enable the function of navigation assisted by the physical stimulation signal.

[0114] Based on the understanding of the above embodiments, the navigation method provided by the embodiments of the present disclosure can be applied to the following several navigation scenarios:

[0115] For example, in a running training scenario, when a running enthusiast is training, the wearable device can indicate the direction with a microcurrent and prompt whether the speed meets the standard according to the established route and training plan. For example, when performing a long-distance running training, it can guide the runner to complete the training according to the planned route, avoiding affecting the training effect due to getting lost or unreasonable speed.

[0116] For another example, in an outdoor sports scenario, in outdoor sports such as mountain climbing and hiking, the wearable device can be combined with a mobile phone positioning and altitude sensor, etc. The microcurrent prompts the traveling direction, and the temperature gives feedback according to the altitude change, deviation from the preset route, etc., helping outdoor sports enthusiasts to maintain the correct traveling route in a complex natural environment and at the same time understand their own sports status.

[0117] For yet another example, in a warehouse operation scenario, when a staff member is carrying out tasks such as goods handling and sorting in a large warehouse, the wearable device can receive task instructions and route guidance. The microcurrent prompts the direction to the goods storage location, and the temperature prompts whether the best working path is deviated, so as to improve work efficiency and reduce time waste caused by getting lost or unreasonable routes.

[0118] The above mainly introduces the solution provided by the embodiments of the present disclosure from the perspective of methods.
