[0044] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0045] Figure 1 This is a flowchart illustrating the steps of a bilingual navigation method for tourism, executed by a wearable device. This wearable device can be a VR (Virtual Reality) headset, AR (Augmented Reality) headset, or other virtual reality device, or a watch, bracelet, or other device worn on the user's wrist. The bilingual navigation method for tourism includes the following steps:

[0046] In step S10, the target location to be reached by the first user and the target language set by the first user are determined.

[0047] The first user can be a user wearing a wearable device. In the context of bilingual navigation for tourism, the first user can be a tourist.

[0048] The target location that the first user wants to reach is the destination location that the first user wants to reach. This target location can be set by the user or it can be the destination location that the wearable device automatically determines based on the environment in which the first user is located.

[0049] Optionally, in a scenario where the target location is set by the user, the wearable device can receive user setting information sent by the second visitor terminal, which includes the target location.

[0050] A first user (e.g., a tourist) can pre-bind a wearable device to a second tourist terminal (e.g., a mobile phone). After the first user sets their target location on the second tourist terminal, the second tourist terminal generates user setting information, which includes the target location set by the first user. The mobile phone then synchronously sends the user's location information to the wearable device, allowing the wearable device to obtain the target location the first user wants to reach. Understandably, because wearable devices are typically small and portable, their touch buttons are small—both on the screen and on the physical buttons—making it difficult for the first user to easily access these buttons and quickly set their target location. By binding the wearable device to the second tourist terminal, the first user can quickly set their target location on the larger second tourist terminal, and the second tourist terminal will also synchronously send the target location set by the first user to the second tourist terminal, enabling the second tourist terminal to obtain the target location the first user wants to reach.

[0051] The target language set by the first user is the language that the first user is accustomed to using. For example, the target language could be English, Korean, Russian, etc.

[0052] Optionally, the wearable device may also include the target language in the user settings information sent by the second visitor terminal. The user can set the target language on the second visitor terminal, and the target language will be included in the user settings information generated by the second visitor terminal.

[0053] In step S20, a first travel route is determined from the device location where the wearable device is located to the target location.

[0054] The device location of the wearable device is its current real-time location.

[0055] The first travel route is a travel route planned by the wearable device from its current location to the target location set by the user. The first travel route includes at least one travel route.

[0056] In step S30, navigation information is displayed using the target language; the navigation information includes the first travel route.

[0057] Navigation information is displayed in the target language, including at least one of the following: the initial route, obstacle warnings, walking speed, and remaining distance.

[0058] The obstacle warning is used to indicate whether there are obstacles ahead to the first user; the walking speed warning is used to indicate the first user's walking speed; and the remaining distance warning is used to indicate the remaining distance from the first user's current location to the target location.

[0059] Optionally, displaying navigation information in the target language includes: displaying the navigation information in at least one of the following forms: text, images, and audio, using the target language.

[0060] Taking VR glasses as an example of wearable devices, the first route from the device's location to the target location can be displayed on the VR glasses in the form of pictures and text, and voice prompts can be added to indicate whether there are obstacles in front of the user.

[0061] It is understood that bilingual navigation in this disclosure refers to translating navigation information from the initial language into the user-defined target language and then displaying the navigation information in the target language.

[0062] Taking the initial language as Chinese and the target language as English as an example, after the navigation software determines the first route from the location of the wearable device to the target location and outputs navigation information containing the first route in Chinese, it can translate the Chinese navigation information into English navigation information and display it.

[0063] Optionally, in addition to displaying navigation information, the wearable device can also collect image information about the surroundings of the wearable device and translate the text information in the image information into text information in the target language.

[0064] The image information indicates the environmental information around the wearable device. For example, if the wearable device is VR glasses and the first user is a tourist, the tourist can wear VR glasses and the VR glasses can collect image information of the environment in which the tourist is located in real time. If the image information displays a shop name, the shop name can be translated into the target language and displayed; if the image information displays a street name, the street name can also be translated into the target language and displayed.

[0065] In some scenarios, assuming the primary user is a tourist, the tourist's destination is the guide's location, the tourist's target language is English, and the wearable device is VR glasses, the tourist can wear VR glasses and set the guide's location. The VR glasses will then display real-time navigation information in English from the tourist's current location to the guide's location, enabling the tourist to navigate to the guide's location based on the displayed navigation information.

[0066] The above technical solution can determine the target location and target language set by the first user, and determine the first route from the wearable device's location to the target location, displaying navigation information in the target language. During this process, because the wearable device integrates navigation and translation functions, after the first user wears the device, it can display navigation information from the device's location to the target location in the user's preferred target language. The first user does not need to consult a translation system while navigating, bringing convenience to the user and improving the user experience.

[0067] Figure 2 This is an exemplary embodiment of the present disclosure, one of the exemplary schemes for interpreting and determining the target location to be reached by a first user, including the following steps:

[0068] In step S11, the first position is obtained when the distance between the wearable device and the target device is greater than a first preset distance and the position of the target device is within a first preset range.

[0069] The target device is a device used by a second user, who can be a tour guide. Therefore, the target device can be a device used by the tour guide. The target device can be a wearable device (such as VR glasses, AR glasses, watches, etc.) or a terminal device such as a mobile phone, computer, or tablet.

[0070] The first preset range is the range obtained with the target device's position as the center and a second preset distance as the radius, assuming the distance between the wearable device and the target device is less than or equal to a first preset distance. This first preset range can also be considered as the user's field of vision. Please refer to [link / reference]. Figure 3 As shown, when the distance between the wearable device and the target device is less than the first preset distance, it means that the wearable device is close to the target device. At this time, the first preset range of the target device's activity can be determined. The first preset range of the target device's activity is obtained by taking the position of the target device as the center and the second preset distance as the radius. The target device is active within the first preset range, or it can be considered that the target device is in a stationary state.

[0071] The second preset distance is less than or equal to the first preset distance. Taking a second preset distance of 20m and a first preset distance of 50m as an example, if the distance between the wearable device and the target device is less than 50m, the wearable device is considered to be close to the target device. At this time, the position of the target device can be obtained, and the first preset range is obtained with the position of the target device as the center and a radius of 20m. When the target device moves within the first preset range, it is considered to be in a stationary state.

[0072] The first location is the device location of the wearable device when the distance between the wearable device and the target device reaches a first preset distance, or it can be the departure location of the first user holding the wearable device when leaving the tour group of the second user holding the target device.

[0073] Taking a first preset distance of 50m as an example, when the distance between the wearable device and the target device reaches 50m, it is considered that the wearable device is far from the target device. At this time, the device position of the wearable device when the distance between the wearable device and the target device reaches 50m can be obtained, and the device position of the wearable device at this time can be used as the target position.

[0074] In some scenarios, taking a first preset distance of 50m and a first preset range as a circle with the target device as the center and a second preset distance of 20m as the radius, and taking a tourist as the first user and a tour guide as the second user as the second user, if the distance between the wearable device worn by the tourist and the target device held by the tour guide is greater than the first preset distance of 50m, it is determined that the tourist is far from the tour guide and has left the tour guide's position within the tour group. In this case, the first preset range of the tour guide's activity can be obtained with the tour guide's position as the center and the second preset distance of 20m as the radius. If the tour guide is within this first preset range, it can be considered that the tour guide is not moving. At this time, the tourist's position when the distance between the tourist and the tour guide is 50m can be obtained, and this tourist's position can be used as the final target position that the tourist needs to navigate to. Of course, this tourist's position is also the tourist's departure point from the tour group.

[0075] Understandably, if the distance between the tourist and the tour guide exceeds the first preset distance of 50 meters, it indicates that the tourist may have gone to the restroom or visited other places, causing the tour guide to be out of the tourist's sight. In this case, the tourist's previous departure point from the tour group can be used as the tourist's final destination. This allows the departing tourist to use navigation information to smoothly return to their previous departure point. When the tourist returns to their previous departure point, the tour guide will reappear within the tourist's sight, enabling the tourist to rejoin the group smoothly. Here, the departure point is the tourist's position when the distance between the tourist and the tour guide is 50 meters.

[0076] Furthermore, since the first preset range is relatively small, tourists can still see the tour guide moving within the first preset range when they return to their original departure position after leaving the group. Therefore, when the tour guide is moving within the first preset range, it can be considered that the tour guide is in a stationary state.

[0077] Using the above technical solution, the first location is obtained when the distance between the wearable device and the target device is greater than a first preset distance, and the location of the target device is within a first preset range. When a tourist is far from the tour guide and the tour guide is moving, the tourist's departure point from the tour guide can be taken as the tourist's final destination. This allows for the planning of a first route from the current location to the destination. Following this first route, the tourist can smoothly return to their previous departure point and rejoin the group.

[0078] Furthermore, compared to the solution of obtaining the tour guide's location in real time and using it as the final destination for tourists, this solution only needs to obtain the tourist's departure location once and use that departure location as the destination location, without needing to obtain the tour guide's location in real time. This reduces the network resource consumption caused by obtaining the tour guide's location in real time.

[0079] Figure 4 This is an exemplary embodiment of the present disclosure, which is a second exemplary scheme for interpreting the determination of the target location to be reached by a first user, including the following steps:

[0080] In step S12, if the distance between the wearable device and the target device is greater than a second preset distance, and the location of the target device is outside the first preset range, the second location periodically sent by the target device is received.

[0081] The second location is the real-time location of the target device.

[0082] When the distance between the wearable device and the target device is greater than the second preset distance, it indicates that the tourist holding the wearable device is far away from the tour guide holding the target device. Furthermore, if the location of the target device is determined to be outside the first preset range, it indicates that the tour guide's location has changed significantly and the tour guide is in a moving state. In this case, even if the tourist who left the group successfully returns to the previous departure location, there is no tour guide within the first preset range. Therefore, in this situation, the second location periodically sent by the target device can be received.

[0083] Optionally, if the distance between the wearable device and the target device is greater than a second preset distance, and the location of the target device is outside the first preset range, the target device may periodically send its second location to the wearable device.

[0084] Taking an interval of 3 seconds as an example, when the distance between the wearable device and the target device is greater than the second preset distance, and the position of the target device is outside the first preset range, the target device can send its second position to the wearable device every 3 seconds, so that the wearable device can obtain the real-time changing second position of the target device.

[0085] Through the above technical solution, when the distance between the wearable device and the target device is greater than a second preset distance, and the target device is located outside the first preset range, the system receives a second location periodically sent by the target device. During this process, even when the tourist is far from the tour guide and the tour guide is moving, the system can receive the second location sent by the target device held by the tour guide in real time, thereby enabling real-time planning of a first route from the wearable device to the target device based on the periodically updated second location of the target device.

[0086] Figure 5 This is an exemplary embodiment of the present disclosure, used to illustrate an exemplary solution when the remaining battery power of a wearable device is low, including the following steps:

[0087] In step S40, if the remaining battery power of the wearable device is lower than the first preset battery power, a first prompt message is sent to the target device.

[0088] The first prompt message is used to indicate to the target device that the remaining battery power of the wearable device is too low. The first prompt message can also instruct the target device to generate a location acquisition request, which is used to request the device location of the wearable device.

[0089] Understandably, when the remaining battery power of the wearable device is lower than the first preset battery level, it means that the remaining battery power of the wearable device is low. In order to avoid the situation where the wearable device runs out of power and the target device cannot contact the wearable device, the wearable device can send a first prompt message to the target device so that the target device knows that the wearable device is about to run out of power and thus take subsequent countermeasures.

[0090] In step S50, in response to receiving the location acquisition request from the target device, the device location of the wearable device is sent to the target device.

[0091] The device location of the wearable device is used to instruct the target device to generate a second travel route from the target device to the wearable device based on the device location of the wearable device.

[0092] Optionally, in response to receiving a first prompt message from the wearable device, the target device sends a location acquisition request to the target device; in response to receiving the device location from the wearable device, the target device generates a second travel route from the target location to the wearable device. This second travel route is displayed on the target device in a target language set by a second user.

[0093] When the remaining battery power of the wearable device is lower than the first preset battery power, it indicates that the remaining battery power of the wearable device is low. At this time, a first prompt message can be sent to the target device to notify the target device that the remaining battery power of the wearable device is low. The target device then sends a location acquisition request to the wearable device. The wearable device sends its own device location to the target device. The target device generates a second travel route from the target device's device location to the wearable device's device location. Then, the second user holding the target device (e.g., a tour guide) can navigate to the location of the first user wearing the wearable device (e.g., a tourist) based on the second travel route.

[0094] Optionally, after receiving a location acquisition request from the target device, the wearable device may also output a second prompt message, which is displayed in the target language set by the first user, and is used to prompt the first user to wait for the second user in place.

[0095] Through the above technical solution, when the wearable device has low remaining battery power, the target device can generate a second route from the target device to the wearable device based on the wearable device's location. This allows a second user holding the target device to find the first user wearing the wearable device based on the second route, reducing the risk of the first user losing contact with the first user holding the target device due to the wearable device running out of power. For example, when a tourist's wearable device has low battery power, a tour guide holding the target device can determine a second route from their current location to the wearable device's location. The tour guide can then find the tourist based on this second route and continue the tour, thus reducing the impact of language barriers on the tourist's experience.

[0096] Furthermore, after the wearable device receives the location acquisition request from the target device, it will also output a second prompt message to remind the first user to wait for the second user in place, thereby reducing the occurrence of situations where the second user has already arrived at the location of the first user, but the first user has moved to another location.

[0097] Figure 6 This is an exemplary solution disclosed herein, used to interpret the real-time display of the positions of a first user and a second user on a wearable device, including the following steps:

[0098] In step S60, a map of the scenic area where the first user is located is obtained.

[0099] Optionally, wearable devices can obtain scenic area maps from scenic area servers or map service providers via the internet. These maps contain information such as the location of various attractions, road layout, entrances and exits, activity areas, and rest areas.

[0100] For example, wearable devices can determine whether their location is within the scenic area. If the location is within the scenic area, the scenic area map can be loaded automatically. If the location is outside the scenic area, the name of the scenic area can be manually entered on the wearable device, and the wearable device will then obtain the scenic area map from the scenic area server corresponding to that name.

[0101] It is understandable that the scenic area map where the first user is located is also the scenic area map where the second user is located.

[0102] In step S70, the target location and the device location of the wearable device are displayed on the scenic area map.

[0103] Optionally, the target location of the target device and the device location of the wearable device can be distinguished by different colors on the scenic area map. For example, the target device is marked in red, and the wearable device is marked in blue. Furthermore, the target location and the device location of the wearable device displayed on the scenic area map will dynamically change according to the location of each user.

[0104] Through the above technical solution, when the first user wearing the wearable device uses the wearable device, the wearable device can display a scenic area map and display the location of the tour guide holding the target device and the location of the tourist wearing the wearable device in real time on the scenic area map, thereby determining the relative position and relative distance between the tour guide and the tourist, thus providing a reference for the tourist's travel route after leaving the group.

[0105] Figure 7 This is an exemplary solution disclosed herein, used to interpret multiple location information of multiple first tourist terminals sent by a target device, including the following steps:

[0106] In step S80, multiple location information of multiple first tourist terminals sent by the target device are received.

[0107] Multiple location information is sent when the remaining battery power of the target device is less than the second preset remaining battery power.

[0108] Optionally, the target device can be bound to multiple first tourist terminals. When the remaining battery power of the target device is less than a second preset battery power, the target device can send multiple location information of the bound first tourist terminals to the wearable device.

[0109] In some scenarios, when a tour guide is leading multiple tourists on a tour with the target device, the tour guide can bind the target device to the first tourist terminal of multiple tourists, and use any one of the first tourist terminals as the wearable device proposed in this disclosure, and send the location information of the other first tourist terminals to the wearable device, so that any tourist in the tour group can perceive the location of other tourists.

[0110] In step S90, at least one of the multiple location information is used as the target location.

[0111] Optionally, the regions where multiple location information of multiple first visitor terminals are located can be sent to the wearable device.

[0112] In some scenarios, if the remaining battery power of the target device is less than the second preset battery power, it indicates that the remaining battery power of the target device is low. In this case, in order to enable the wearable device that has left the group to return to the tour group smoothly, at least one of the multiple location information of multiple first tourist terminals bound to the target device, or the location area of ​​multiple first tourist terminals, can be sent to the wearable device so that the tourist holding the wearable device can know the location of the tour group.

[0113] Optionally, the distance between the two farthest first visitor terminals among the plurality of first visitor terminals is less than a third preset distance. For example, please refer to... Figure 8 As shown, the target device detects multiple first tourist terminals bound to it, namely tourist terminal A, tourist terminal B, tourist terminal C and tourist terminal D. Among them, the distance between tourist terminal A and tourist terminal D is the farthest. Then it will determine whether the distance between tourist terminal A and tourist terminal D is less than a third preset distance. If it is less than the third preset distance, it means that the distance between tourist terminal A, tourist terminal B, tourist terminal C and tourist terminal D is relatively close.

[0114] The target device can cluster multiple first tourist terminals bound to it, thereby dividing the multiple tourist terminals into multiple different groups and eliminating tourist terminals outside the groups. This ensures that the distance between the two farthest tourist terminals within a single group is less than a third preset distance. In this way, the multiple location information sent to the multiple first tourist terminals of the wearable device is more concentrated tourist information, rather than scattered tourist information, so that tourists holding wearable devices can be successfully navigated to the concentrated tourist location within the tour group.

[0115] Through the above technical solution, when the target device's remaining power is less than the second preset power, it will send multiple location information of multiple first tourist terminals bound to it to the wearable device. The wearable device will use at least one of the multiple location information as the final target location to be reached. In this way, before the target device used by the tour guide runs out of power, it can send multiple location information of multiple first tourist terminals gathered in the tour group to the wearable device, providing a reference destination for the wearable device to return to the group.

[0116] Figure 9 This is an exemplary embodiment involving step S20 above, which is used to interpret an exemplary scheme for obtaining the first travel route, including the following steps:

[0117] In step S21, the travel costs of multiple routes from the device location to the target location are determined.

[0118] The A* algorithm can generate multiple travel routes from the device location to the target location by dividing the map into a grid model, setting the device location as the starting point and the target location as the ending point.

[0119] For each path, the sequence of nodes it passes through is recorded for subsequent calculation of the travel cost. The travel cost is positively correlated with at least one of the following: travel distance, number of obstacles, and number of turns.

[0120] For example, the sum of distances between all nodes on the travel path can be calculated as the walking distance; the number of obstacles on each travel path can be counted, and the more obstacles there are, the higher the cost score; for example, the angle between two adjacent positions of the first user can also be calculated, and if the angle is greater than a threshold (e.g., 90 degrees), it is considered a turn.

[0121] When calculating the cost of traveling a certain route, the cost can be obtained based on the distance traveled, the first weight corresponding to the distance traveled, the number of obstacles, the second weight corresponding to the number of obstacles, the number of turns, and the third weight corresponding to the number of turns. The calculation formula is as follows:

[0122] Q = L*W1 + N1*W2 + N2*W3

[0123] Where Q is the cost of traveling the route, L is the distance traveled, W1 is the first weight corresponding to the distance traveled, N1 is the number of obstacles, W2 is the second weight corresponding to the number of obstacles, N2 is the number of turns, and W3 is the third weight corresponding to the number of turns.

[0124] In step S22, the first travel route with the lowest travel cost is selected from multiple travel costs.

[0125] The first route with the lowest walking cost means that the cost for the first user holding the wearable device to reach the second user holding the target device is relatively small, such as a shorter walking distance, fewer obstacles encountered, or fewer turns.
