Description

Technical Field

[0001] The present invention relates to the field of automated prompting of buses and bus stops, and in particular to a method and system for providing public transportation information prompting for the elderly. Background Art

[0002] Existing mobile apps are complex to use, feature unclear interfaces, small fonts, and difficult interactions. They serve all passengers, relying on traditional bus stop signage, active input from mobile users, or inquiries via electronic bus stop signs. Information is primarily presented in text or graphics, lacking multi-channel feedback via touch, vision, and hearing, making it less user-friendly for the elderly. The system architecture is universal, applicable to all passengers, and lacks age-friendly design.

[0003] Problems with existing mobile phone software:

[0004] 1) Many bus stops in cities and rural areas of my country do not have electronic bus stops. In areas where electronic bus stops have been built, the coverage rate is low, the construction cost is high, and maintenance is difficult. It is inconvenient for the elderly to obtain information and the waiting time is long.

[0005] 2) Existing travel service systems rely on smartphones, touch screens, or physical buttons (such as query terminals), requiring users to actively query and operate. The interface functions are redundant (such as map navigation and pop-up ads), and the interface fonts are small and the layout is dense. Due to lack of operational expertise or limited vision, it is difficult for the elderly to quickly complete interactions (such as accidental touches, inability to find buttons, etc.).

[0006] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0007] In response to the problems in the related art, the present invention proposes a method and system for providing public transportation information prompts for the elderly to overcome the above-mentioned technical problems existing in the existing related art.

[0052] Figure 2 This is a structural block diagram of a public transportation information prompt system for the elderly according to an embodiment of the present invention;

[0053] Figure 3 This is the second flowchart of a method for providing public transportation information prompts to the elderly according to an embodiment of the present invention. DETAILED DESCRIPTION

[0054] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention.

[0055] According to an embodiment of the present invention, a method and system for providing public transportation information prompts for the elderly are provided.

[0056] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1 As shown, a method for providing public transportation information prompts for the elderly according to an embodiment of the present invention includes:

[0057] Step S1: When a user uses a mobile application (i.e., a mobile phone) for the first time, he / she needs to set up location service authorization and complete the personalized setting of the travel range (i.e., the starting station, the destination station, and the route) through voice commands;

[0058] It should be noted that the automatic association of stations and routes based on mobile phone location information is different from the traditional method that requires users to manually input or select stations / routes. This method uses the mobile phones carried by the elderly as positioning anchor points, and continuously or periodically obtains the GPS, base station or Wi-Fi location information of the mobile phone through the background, and combines it with electronic map data to automatically determine the user’s current or nearby bus stop, and accurately distinguish between up and down buses, match the route information of the passing stations, and realize the "spatial" automatic association of information.

[0059] Step S2: Using the personalized travel pattern model, record the new travel interval information inquired by the user through voice commands;

[0060] It should be noted that the system automatically matches stops and routes based on travel patterns: Considering that elderly people may frequently travel between several fixed locations, such as home and hospitals, supermarkets, and parks, the system analyzes users' historical travel records (e.g., frequently taking specific routes from specific stops during specific time periods) to establish a personalized travel pattern model. When the system detects that the user's current location is near a bus stop they frequently visit at their usual travel time, even without explicit query instructions, it can automatically determine that the user has a need for a bus and prioritize push real-time vehicle information (such as estimated arrival time) for the routes they frequently take.

[0061] Step S3: Based on the personalized travel pattern model, when the mobile terminal approaches the identification radius of the travel interval, the application is automatically activated and the location information of the user and the travel interval is matched in combination with the electronic map data;

[0062] Step S4: The backend server receives and matches the user's location information with the bus interval, and uses a low-interaction mechanism to enable the mobile backend to continuously monitor the location and provide the user with a multi-modal reminder of the upcoming bus route and the estimated arrival time at the target stop.

[0063] Step S5: Based on the family care mechanism and the safe arrival notification mechanism, multiple application accounts are bound and the user's travel information is pushed to the family;

[0064] Step S6: Utilize feedback channels to collect user feedback and continuously optimize the interface design and interaction process of the application.

[0065] In this optional embodiment, when a user uses the mobile application for the first time, the user performs the location service authorization settings and completes the personalized settings of the travel interval through voice commands, including:

[0066] Step S11: When a user uses the mobile application for the first time, the user performs location service authorization settings. After the location service is authorized, the application background continuously monitors the geographical location information of the mobile terminal;

[0067] Step S12: Complete the personalized settings of the starting site, target site, and route through voice commands.

[0068] It should be noted that when a user uses the APP for the first time, a one-time initialization setting is required, including agreeing to the location service authorization. After the location service authorization, the APP background continuously monitors the user's geographic location information. At the same time, the user can complete some personalized settings through voice commands at this stage.

[0069] In this optional embodiment, using the personalized travel pattern model to record the new travel interval information inquired by the user through voice commands includes:

[0070] Step S21: Automatically match the starting station, target station, and route based on the user's query instruction to form a user travel record and build a personalized travel pattern model;

[0071] Step S22: The personalized travel pattern model records the user's historical travel patterns and automatically identifies the user's frequently used starting and destination sites and routes.

[0072] It should be noted that when users use it for the first time, they can set the boarding and alighting stops or routes through voice commands. The system also records the user's historical query records and riding habits, automatically identifies the user's frequently used bus stops and routes, and in the information display interface, frequently used route information is displayed first to improve the efficiency of information acquisition.

[0073] In this optional embodiment, based on the personalized travel pattern model, when the mobile terminal approaches the identification radius of the ride interval, the application is automatically activated and, in combination with the electronic map data, the location information of the user and the ride interval is matched, including:

[0074] Step S31: using the positioning system on the mobile terminal to obtain the location information of the user and the starting station or the target station, and the departure interval of the line to be taken;

[0075] Step S32: Automatically activate the application, dynamically adjust the application activation recognition radius, and combine it with electronic map data;

[0076] Step S33: automatically determine the location of the user and the starting site or the target site, distinguish the coming and going directions of the vehicle, and match the location information of the user and the starting site or the target site.

[0077] It should be noted that when using the app for the first time, users can set boarding and alighting stops or routes through voice commands. When approaching a set boarding and alighting stop area for a bus route they have already taken, the positioning module detects the user's location and automatically triggers the app to activate. The system dynamically adjusts the software activation recognition radius by obtaining the departure interval of the route to be taken. The recognition radius for routes with a short departure interval of less than 5 minutes is 50 meters, and the recognition radius for routes with a long departure interval of more than 10 minutes is 200 meters. The recognition accuracy can distinguish between getting on and off vehicles. The activation process does not require manual operation by the user. The app automatically enters the bus information display interface when the screen is off. The user will not recognize intermediate bus stops while riding the bus. The system can record the user's travel data and automatically pop up arrival and home navigation reminders when the user approaches the last get-off stop.

[0078] In this optional embodiment, based on the backend server receiving and matching the user's location information with the travel interval, and utilizing a low-interaction mechanism, the mobile terminal backend performs continuous positioning monitoring, and the multimodal notification of the user's upcoming bus route and the target stop's estimated arrival time includes:

[0079] Step S41: After receiving the location information matching the user and the travel interval, the backend server extracts the bus arrival information from the real-time bus data source;

[0080] Step S42: Formatting the real-time data source of public transportation according to the principle of aging-friendly design using a low-interaction mechanism;

[0081] Step S43: The multimodal prompt mode supports various prompt forms such as voice broadcast, vibration reminder and high contrast display;

[0082] Step S44: When the mobile terminal approaches the starting station or the target station of the travel interval, a navigation reminder for arrival or return home will pop up automatically.

[0083] It should be noted that the low-interaction automatic push of route and vehicle information completely changes the passive model of traditional bus information systems, which require users to actively query. Using a low-interaction design, the system proactively pushes information such as bus routes and estimated arrival times to seniors, and pushes travel information to their families. Push notifications support a variety of methods, including voice broadcasts, vibration reminders, and high-contrast displays, eliminating the clicks and searches required by traditional apps. This breaks through the single-mode display limitations of traditional bus stop signs from the perspectives of vision, hearing, and touch, and specifically implements voice wake-up query functions, achieving "lightweight and aging-friendly transformation."

[0084] Users can preset various forms of information reminders in the APP in advance, including: Voice broadcast: The system automatically broadcasts the upcoming bus routes and estimated arrival times; Vibration reminder: The phone vibrates to remind the user within a set time before the estimated arrival time; High-contrast display: Key information is displayed in high-contrast colors to facilitate identification by elderly people with poor eyesight.

[0085] In this optional embodiment, after the backend server receives the location information matching the user and the travel interval, it extracts the bus arrival information from the real-time bus data source, including:

[0086] Step S411: The data processing mechanism filters and organizes the obtained bus arrival information, and extracts key information in combination with the priority sorting mechanism.

[0087] It's important to note that after receiving the positioning information, the backend server retrieves the arrival information for the relevant routes from the real-time bus data source. The data processing module systematically screens and organizes this information, including cleaning to remove duplicate, invalid, or abnormal data, such as excluding vehicle location information that hasn't been updated for a long time. It also uses a priority sorting mechanism to extract key data, such as the current route number, the estimated arrival time of the next bus, and the number of stops from the current location, ensuring concise and clear information.

[0088] In this optional embodiment, using a low-interaction mechanism and formatting the real-time bus data source according to the principle of aging-friendly design includes:

[0089] Step S421: Based on the extracted key information, enlarge the font, enhance color contrast, simplify the interface layout, reduce the information hierarchy, and use icons to aid understanding according to the principles of aging-friendly design;

[0090] Step S422: The user views the processed key information through sliding, clicking, or voice commands.

[0091] It should be noted that the system formats data according to the principles of aging-friendly design, including enlarging fonts, enhancing color contrast, simplifying interface layout, reducing information levels, and using icons to assist understanding, so that the elderly can quickly identify core content. In addition, the voice interaction entrance is highlighted in the interface, making it convenient for users to obtain information or perform operations through voice. When the user is detected approaching a bus stop, the system will display push information through the system-level notification bar or lock screen. The information push adopts a simple and eye-catching design to ensure that it can be clearly seen even when the screen is off. The information display interface adopts a large font and high contrast design to ensure that the elderly can clearly identify it. Users can view information on different routes with simple sliding or clicking operations or voice commands.

[0092] In this optional embodiment, based on the family care mechanism and the safe arrival notification mechanism, multiple application accounts are bound and the user's travel information is pushed to the family members, including:

[0093] Step S51: Based on the family care mechanism, the family can view the elderly person's real-time location, current bus route and estimated arrival time in the application by binding the user's application account;

[0094] Step S52: Based on the safe arrival notification mechanism, when the user successfully gets on the bus or approaches the destination, a text or voice reminder is automatically triggered and sent to the family account to confirm the user's travel status.

[0095] It should be noted that the system provides a family care module that supports account binding to family members, which is particularly suitable for children to keep an eye on the travel of elderly family members. Through this module, children can view the elderly person's real-time location, current bus route, estimated arrival time, and other information in the app. The system also has a built-in "safe arrival notification" mechanism. When the elderly person successfully boards the bus and approaches the destination, a text or voice reminder is automatically triggered and sent to the designated relatives to confirm their travel status and enhance their sense of travel safety. All data transmission involved is encrypted to protect user privacy and information security.

[0096] In this optional embodiment, utilizing feedback channels to collect user feedback and continuously optimizing the interface design and interaction process of the application program includes:

[0097] Step S61: Provide a user feedback channel based on the application, collect user opinions and suggestions during use, and optimize the interface design and interaction process based on user feedback.

[0098] It should be noted that the system provides a user feedback channel to collect opinions and suggestions from the elderly during use. Based on user feedback, the interface design and interaction process are continuously optimized to enhance the user experience.

[0099] like Figure 2 As shown, according to another embodiment of the present invention, a public transportation information prompting system for the elderly is provided, and the prompting system includes:

[0100] Program setting module 1 is used for the first time when a user uses the mobile application to perform location service authorization settings and complete the personalized setting of the travel range through voice commands;

[0101] Information recording module 2, used to record new travel interval information inquired by users through voice commands using a personalized travel pattern model;

[0102] Information matching module 3 is used to automatically activate the application when the mobile terminal approaches the identification radius of the travel interval based on the personalized travel pattern model, and match the location information of the user with the travel interval in combination with the electronic map data;

[0103] Information monitoring module 4 is used to receive and match the user's location information with the bus interval based on the backend server, and use a low-interaction mechanism to enable the mobile backend to perform continuous positioning monitoring, and multi-modally prompt the user of the upcoming bus route and the target station's estimated arrival time;

[0104] Information push module 5, used to bind multiple application accounts based on the family care mechanism and safe arrival notification mechanism, and push the user's travel information to the family;

[0105] The program optimization module 6 is used to collect user feedback through feedback channels and continuously optimize the interface design and interaction process of the application.

[0106] In summary, with the help of the above technical solution of the present invention, it is possible to automatically determine whether the user has entered the target station area based on location sensing technology without manual operation by the user. Its core features include: first, a non-sensing trigger mechanism, which automatically and dynamically activates the app through mobile phone positioning after the app is opened in advance; second, intelligent information aggregation, which integrates real-time arrival data of multiple bus routes and designs an elderly-friendly display interface; third, a low-interaction design, which can push arrival information even when the screen is off, simplifying the clicks, searches, and other steps required by traditional apps; fourth, multi-modal prompts, which support voice broadcasts, vibration reminders, and high-contrast displays, providing users with a convenient and efficient bus information service experience; fifth, user preference memory for frequently used routes, which pushes route information of passing stations in order of frequency; and sixth, support for account binding with family members, which tracks the travel status of the elderly at any time and ensures their safety.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
