It should be noted that the navigation information generated based on the navigation instruction input by the user can be generated by not only the server corresponding to the automobile terminal but also the processor of the automobile terminal itself.

FIG2 is a flow chart of a navigation information display method provided by an embodiment of the present application. The navigation information display method may be executed by an in-vehicle navigation system in a vehicle, for example, the computer device may be the vehicle terminal 120 shown in FIG1 above, or the computer device may be other computer devices, such as a server, or a personal computer, etc. The navigation information display method may include the following steps:

Step 210: Obtain user static information set by the driver user; the user static information at least includes the age of the driver user.

The driver user is a user who drives a car corresponding to the current in-vehicle navigation system.

The above user static information is the common information or fixed information of the user account corresponding to the current in-vehicle navigation system, and the user static information at least includes the age information of the driver user.

Optionally, the user static information may also be at least one of the driver's frequently used destinations, the language preference of the vehicle navigation system, and the user's gender information.

In an embodiment of the present application, the vehicle navigation system can obtain user static information by querying the terminal/server database according to the login account corresponding to the vehicle navigation system; it can also obtain user static information based on the driver's input/setting operations on the terminal interface of the vehicle navigation system.

In the embodiment of the present application, the user (specifically, the driver or the passenger) can set the user static information by triggering the terminal interface of the vehicle navigation system. The triggering operation can be, but is not limited to, at least one of a single click, a double click, a long press operation, a sliding operation, and an input operation. In some embodiments, the user can also set the user static information by voice commands, gesture commands, etc. The user's setting operation of the static information can be, but is not limited to, at least one of an adding operation, a deleting operation, a query operation, and a modifying operation.

Step 220: Acquire user dynamic information, which includes at least one of interaction information and emotion information; the interaction information is used to indicate the interaction between the driver user and the navigation interface of the vehicle navigation system, and the emotion information is used to indicate the emotion of the driver user.

The user dynamic information is real-time, dynamic data and information generated by the driver when using the vehicle navigation system, and the user dynamic information includes at least one of interaction information and emotional information.

Among them, the above-mentioned interactive information is the information generated by the driver user operating the navigation interface of the vehicle navigation system during navigation using the vehicle navigation system, such as operation interaction actions (such as interface zoom-in operation, interface zoom-out operation, etc.), operation task completion time, and error rate.

Among them, the above-mentioned emotional information is the emotional information of the current driver user when driving a car, such as the user's facial data (such as facial expressions), eye movement data (such as blinking frequency, eye movement direction) and EEG data (different brain wave frequencies), heart rate data, etc.

In the embodiment of the present application, the vehicle navigation system can obtain user dynamic information by querying the database in the terminal/server, or by collecting user dynamic information through sensors set in the vehicle navigation system. The sensors in the vehicle navigation system can be but are not limited to at least one of the following:

1) Global Positioning System: The Global Positioning System is used to determine the current location and direction of movement of the vehicle. By analyzing GPS data, the in-vehicle navigation system can obtain information such as the user's driving trajectory, speed, and driving direction, thereby providing real-time navigation guidance and route planning.

2) Vehicle speed sensor: The vehicle speed sensor is used to detect the real-time speed of the vehicle. By recording the current speed of the vehicle, the navigation system can determine whether the current vehicle is in a congested state and adjust the navigation route accordingly or provide traffic condition prompts.

3) Voice recognition sensor: Voice recognition sensor is used to recognize the voice commands of the driver. Through voice recognition technology, the in-vehicle navigation system can obtain the destination, route preference and other information input by the user in real time, thereby providing more convenient navigation services.

4) In-car camera: In-car camera can be used to record the facial expressions and behaviors of the driver. Through facial expression recognition technology, the in-car navigation system can infer the driver's emotional information, such as happiness, fatigue, etc., and adjust the navigation interface or provide corresponding driving suggestions.

5) Heart rate sensor: The heart rate sensor is used to record the driver's heart rate changes. By analyzing the heart rate data, the driver's current emotional and physical state can be inferred.

In the embodiment of the present application, the above-mentioned sensor can collect data through the hardware device of the vehicle navigation system or the connected external device. After the data is collected, the vehicle navigation system can obtain the dynamic information of the driver user through signal processing and analysis algorithm.

Step 230: Determine the information display style according to the user static information and the user dynamic information.

The above information display style is a display style on the interface of the in-vehicle navigation system corresponding to the navigation information generated by the in-vehicle navigation information based on the user static information and the user dynamic information.

In an embodiment of the present application, the terminal/server of the vehicle navigation system contains at least one database for storing at least two information display styles, wherein each information display style corresponds to a user static information/user dynamic information, and different information display styles correspond to different user static information/user dynamic information; in another possible manner, the terminal/server of the vehicle navigation system can instantly generate an information display style based on the user static information and the user dynamic information by setting itself/calling a machine learning model of a third-party platform.

In an embodiment of the present application, the vehicle navigation system can determine the navigation information display style in three ways: determining the information display style based on user static information, determining the information display style based on user dynamic information, and determining the information display style based on user static information and user dynamic information.

In the case where the in-vehicle navigation system determines the information display style based on the user static information of the driver user, the in-vehicle navigation system determines that the specified style is the display style of the generated navigation information on the terminal interface in response to the user static information satisfying the specified condition. Exemplarily, the in-vehicle navigation system responds to the user static information set by the driver user being "age", the specific age is "59", and the specified condition is that the age is greater than 50. After the in-vehicle navigation system detects that the user's age is greater than 50, it can search for a display style that matches the age of 59 in its own data (double the default display mode), and at this time the in-vehicle navigation system enlarges and displays the navigation information on the navigation terminal interface.

In the case where the in-vehicle navigation system determines the information display style based on the user dynamic information of the driver user, the in-vehicle navigation system determines that the specified style is the display style of the generated navigation information on the terminal interface in response to the acquired user dynamic information satisfying the specified conditions. Exemplarily, the above-mentioned specified conditions include: the user's emotions are "confused", "anxious" and other emotions, the in-vehicle navigation system recognizes the facial expression features of the current driver user through its own sensors, and analyzes the facial expression features by calling the machine learning model of the cloud server, and obtains that the facial expression belongs to "confusion", which satisfies the above-mentioned specified conditions. At this time, the specified navigation information display style can be determined, and in the specified navigation information display style, the display brightness of the key content in the navigation information is increased, such as highlighting the destination route or destination name of this trip.

When the in-vehicle navigation system determines the information display style based on the static user information and dynamic user information of the driver user, the in-vehicle navigation system can generate a target information based on the above two types of information, and in response to the target information satisfying specified conditions, determine that the specified style is the display style of the generated navigation information on the terminal interface.

Exemplarily, the specified conditions are: the user is a middle-aged or elderly person; assuming that the static information of the driver user is "age 56 years old", the dynamic information is the interactive information "operation error rate 90%" and the emotional information "anxiety", the in-vehicle navigation system combines the static information and the dynamic information to generate the target information "middle-aged and elderly people", which meets the above specified conditions. At this time, the in-vehicle navigation system determines that the display style of the navigation information is the specified style based on the target information of the driver user. Under the specified style, the navigation information (navigation route and destination location) is displayed flashing on the terminal interface.

Step 240: Display navigation information of the vehicle navigation system according to the information display style.

In the embodiment of the present application, after the in-vehicle navigation system acquires the display style corresponding to the navigation information, the corresponding navigation information is displayed on the interface of the in-vehicle navigation system according to the specified information display style.

It should be noted that the user static information and user dynamic information in the application embodiment of Figure 2 only take the user as a driver as an example. In other possible implementations, the user static information and user dynamic information may also be the information of a passenger (i.e., a non-driver user); the above-mentioned servers are all servers corresponding to the terminal devices of the vehicle navigation system, and may also be corresponding cloud servers.

In an embodiment of the present application, the in-vehicle navigation system may first obtain user static information and user dynamic information corresponding to the driver user, and based on these two types of information, determine the display style of the navigation information in the interface of the in-vehicle navigation system; determine different navigation information display modes through user static information and user dynamic information, expand the method of displaying navigation information, and determine the display style of the navigation information based on these two types of information, which is more suitable for the current driving state of the driver user, thereby improving the display effect of the navigation information.

In some embodiments, the user dynamic information further includes at least one of the following information: vehicle information, environmental information, and information of people outside the vehicle;

The vehicle information is used to indicate the driving status of the vehicle;

Environmental information is used to indicate the driving environment in which the vehicle is located;

The external personnel information is used to indicate the situation of the personnel around the vehicle.

The driving state may be the current speed of the vehicle, and may specifically be a situation where it is determined whether the current vehicle is speeding based on the current driving road of the vehicle.

Among them, the above-mentioned driving environment can be the road information on which the vehicle is currently traveling, such as the road type (for example, expressways, provincial roads, national roads, urban roads, country roads); it can be the natural environment information on which the vehicle is currently traveling, such as ambient light intensity (for example, ultraviolet intensity), weather information (for example, temperature); it can also be the terrain environment information on which the vehicle is currently traveling, such as mountain roads, plains, uphill and downhill.

The situation of the people around the above-mentioned vehicle may be the number of pedestrians around the current vehicle or the distance between the pedestrians and the current vehicle.

In the embodiment of the present application, the user dynamic information may include one or at least two of the above information. The user dynamic information types are expanded, and the vehicle navigation system can determine the display style of the navigation information that is closer to the current driving state of the driver based on different types of user dynamic information, and the method of displaying the navigation information is expanded, thereby improving the effect of displaying the navigation information.

In some embodiments, the above-mentioned user static information also includes at least one of the following information: the education level of the driver user, the occupation of the driver user, and the physical condition of the driver user.

The above-mentioned educational level includes the driver's education level, school and other information.

The physical condition of the driver user may be healthy, good, or sick, and may also be the driver user's medication history, allergy history, and major disease history.

In an embodiment of the present application, user static information may be one or at least two of the above-mentioned information, thereby expanding the type of static information. The vehicle navigation system determines the display style of the navigation information based on different types of user static information, thereby expanding the method of displaying navigation information, and making the display style of the navigation information closer to the user's current state, thereby improving the effect of displaying the navigation information.

Based on the above embodiment, step 230 can be implemented by inputting user static information and user dynamic information into the first model to obtain the information display style output by the first model; wherein the first model is a machine learning model trained by user static information samples, user dynamic information samples and annotated display styles.

Among them, the above-mentioned first model can be trained based on the user static information samples, user dynamic information samples and annotated navigation information display style of the driver user. For example, taking the above-mentioned first model as a model based on a convolutional neural network, during the training process, the vehicle navigation system uses the user static information samples and user dynamic information samples of the driver user as the input of the convolutional neural network, obtains the predicted navigation information display style output by the convolutional neural network, and then calculates the loss function value through the difference between the predicted navigation information display style and the annotated navigation information display style, and updates the parameters of the convolutional neural network through the loss function value to complete the training of the convolutional neural network, and uses the trained convolutional neural network as the first model.

In an embodiment of the present application, the vehicle navigation system can input the received user static information and user dynamic information into a first model with the ability to generate information display styles. The first model processes the input information and obtains an information display style corresponding to the input information. For example, the user static information and user dynamic information can be input into a convolutional neural network to obtain an information display style based on the output of the convolutional neural network.

Exemplarily, the in-vehicle navigation system inputs the user's age information and the user's physical condition information into a convolutional neural network to obtain an information display style output by the convolutional neural network; wherein the convolutional neural network is a machine learning model trained by user age information samples, physical condition samples and annotated display styles.

In an embodiment of the present application, the vehicle navigation system generates an information display style through a first model, which expands the method of generating the information display style. The information display style generated by the trained first model is more in line with the current state of the driver user and can effectively improve the display effect of the navigation information.

Based on the above embodiment, when the user static information meets the specified conditions, the above step 230 can also be implemented by inputting the user dynamic information into the second model to obtain the information display style output by the second model; wherein the second model is a machine learning model trained by user dynamic information samples and annotated display styles.

Among them, the above-mentioned specified conditions can be set by the developer/driver user.

Among them, the above-mentioned second model can be obtained by training based on the user dynamic information samples of the driver user and the annotated navigation information display style. For example, taking the above-mentioned second model as a Haar feature classifier, during the training process, the user dynamic information samples of the driver user are used as the input of the Haar feature classifier to obtain the predicted navigation information display style output by the Haar feature classifier, and then the loss function value is calculated by the difference between the predicted navigation information display style and the annotated navigation information display style. The parameters of the Haar feature classifier are updated by the loss function value to complete the training of the Haar feature classifier, and the trained Haar feature classifier is used as the second model.

For example, when the current driver user's age information is greater than 60 years old, the vehicle navigation system can input the user's emotional information into a Haar feature classifier to obtain the information display style output by the Haar feature classifier; wherein the Haar feature classifier is a machine learning model trained through user emotional information samples and annotated display styles.

In an embodiment of the present application, the vehicle navigation system can input the received user dynamic information into a second model with the ability to generate information display styles, and generate an information display style suitable for the current status of the driver user through the second model, thereby expanding the method of obtaining the information display style and improving the display effect of the overall navigation information.

In some embodiments, the above information display style is used to indicate at least one of the following:

Display information type, display size, color, brightness, display level, and volume.

The above information type is the display type of navigation information in the vehicle navigation system, and the information type may be at least one of text information, voice information, picture information and video information.

The above display size refers to the display size of the navigation information in the terminal interface of the vehicle navigation system (for example, 8 inches).

The above display levels are the display levels of the navigation information in the terminal interface of the vehicle navigation system, for example, different information is displayed layer by layer according to the priority of the navigation information.

In the embodiment of the present application, the above information display style can be displayed in a fixed style in the terminal interface of the vehicle navigation system, or it can be dynamically adjusted according to the dynamic information and static information of the current driver user. For example, when the terminal device of the vehicle navigation system receives the age information of the current driver user as "56 years old", the font size of the navigation information in the current navigation interface is bolded, and when the vehicle drives to dangerous areas such as intersections, turns, uphill and downhill, the vehicle navigation system automatically enlarges the scene diagram of the dangerous area in the terminal interface, and after the vehicle passes the dangerous area, the scene diagram returns to the default size.

In the embodiment of the present application, the driver user can obtain different navigation information through different information display styles, which expands the information display style, helps the driver user to obtain navigation information more effectively, and thus improves the display efficiency of the navigation information.

Exemplarily, based on the embodiment corresponding to FIG. 2 , the embodiment of the present application proposes an aging-friendly car navigation system based on intelligence and perception technology.

The current in-vehicle navigation systems mainly use visual and voice prompts for navigation, and the interface operations are mainly touch-based. However, the functional structure and operation information of the navigation system are relatively complex. For elderly drivers, due to their limited cognitive and behavioral abilities, they are unable to understand the navigation functions and operation guidance information, which can easily lead to frustration and even cause driving safety problems.

Intelligence and perception technology refers to the study of "human-centered" intelligent information processing and control technology based on biometrics, natural language and dynamic image understanding, and the study of system technologies in related fields such as biometric identification and intelligent transportation. It maps the signals of the physical world to the digital world through hardware devices such as cameras, microphones or other sensors, with the help of cutting-edge technologies such as voice recognition and image recognition, and then further enhances the digital information to a cognitive level, such as memory, understanding, planning, decision-making, etc. In the research process of elderly driving experiments, through intelligence and perception technology, the static and dynamic information of the elderly using the navigation system can be collected and analyzed in real time, which helps to explore the specific impact of interface elements on the operation of the elderly.

Please refer to FIG3 , which shows a functional flow chart of a car navigation system provided by an embodiment of the present application. The system includes a system display unit 320 , an intelligent sensing and computing unit 330 , and a cloud database 340 :

System display unit 320: The system display unit 320 is an important medium for the system to display functions and interact with users. It mainly includes a display screen and a user interface, and is an interface for providing navigation information to the driver and receiving input. Modern navigation systems are usually equipped with high-resolution color displays and intuitive user interfaces so that drivers can easily view maps, routes and other relevant information. The aging-friendly car navigation system display unit 320 not only has a display screen digital interface, but also includes HUD (Heads-Up Display) and gestures and other hardware and software operation structures, providing more options for aging-friendly navigation information interaction.

Intelligent sensing and computing unit 330: The intelligent sensing and computing unit 330 is the basic unit of the car navigation system, which mainly includes GPS vehicle navigation positioning, vehicle's own state perception sensor, user perception unit and intelligent computing and analysis unit. It is composed of an embedded computer or integrated circuit and can effectively collect, process and analyze vehicle, environment, user and other information during vehicle driving.

Cloud database 340: Cloud database 340 is important external information required to complete car navigation driving, including: map data, which covers information such as road networks, geographical features and points of interest. The accuracy and update frequency of map data are crucial to the effectiveness of the navigation system; external space information, mainly real-time changes in people and objects in the external environment, as a supplement to map information; user feature big data, mainly the experience, preferences, habits, etc. of elderly users in using such digital products, provides a basis for the system to process and calculate the information collected by the current user. In addition, cloud database 340 also includes automobile regulations related to car navigation, the latest public related technical patents and some external system data to provide support for real-time adjustment of the system.

Furthermore, after the user uses the above-mentioned car navigation system, the user's operating behavior (corresponding to the interactive information in the above-mentioned embodiment), language expression (corresponding to the emotional information in the above-mentioned embodiment) and task completion status (corresponding to the interactive information in the above-mentioned embodiment) will be recorded and fed back, and will be re-applied in the adjustment of the system.

A) During the information processing and analysis stage, the above-mentioned car navigation system will intelligently process the collected information, simplify the information that elderly users need to access and process (for example, process the information through a machine learning model to obtain simplified information), feedback the operations that need to be performed to the elderly users, and match the elderly users' cognitive logic and operating habits.

B) During the system interface setting phase, the following contents are included:

First of all, regarding the form of interface elements, the car navigation system itself comes with visual and auditory elements of different styles, colors, and sizes, which can be adjusted in real time.

Secondly, the interface information interaction forms also present a variety of methods, including visual interaction, auditory interaction, tactile interaction, gesture interaction, etc., to meet the needs of users with different information conditions. Important functions can be completed with clicks and touches, which are most commonly used by the elderly, and the interaction methods must be consistent between each page.

Finally, the interface information structure follows the principle of simplification, and is streamlined, deleted, and hidden based on the priority of the content, so that the original broad and deep content is extracted and transformed into narrow and shallow core content, and the secondary content or unimportant content is narrow and deep, ensuring that the content is well-organized and clearly layered. The core functions such as navigation, radio, and telephone that have the greatest impact on system usability are extracted to form a shortcut layer and placed on the main page first, so that elderly drivers can complete the task with just one step, improving interaction efficiency.

Based on FIG. 3 above, the best implementation of the above-mentioned aging-friendly car navigation system based on intelligence and perception technology includes the following steps:

Step S1: Preliminary setup input.

Before using the navigation system, the elderly user 310 can input relevant information about himself (age, occupation, hobbies, physical condition, etc.) and navigation-related information such as the desired destination, and wait to start using the navigation function.

Step S2: Navigation data analysis and processing.

After the navigation function starts, by utilizing intelligent and perception technology, based on the intelligent perception and computing unit 330, combined with the cloud database 340, the information involved in the entire process of the elderly user 310 using the navigation system (including the environment, vehicle, and the elderly driver's operating information) is continuously analyzed and processed to provide a basis for the navigation system interface information display.

Step S3: Interface information display feedback.

Based on the results of data analysis, relying on the relevant display and interactive channels of the information display unit, the navigation function's information display and interactive feedback are automatically performed to complete the entire functional process.

In the process of system function practice, the car navigation system will continuously adjust the presentation and interaction of interface information according to the user's operation behavior, such as interface operation interaction behavior, operation task completion time, error rate, eye movement data, EEG data, etc., to improve the user experience and form a virtuous cycle. The relevant experience and data generated can be continuously iterated and used to form a virtuous cycle, and external standards, regulations, and databases can be updated in real time to avoid technological backwardness.

In an embodiment of the present application, an aging-friendly car navigation system based on intelligent and sensing technology is provided, the system comprising an intelligent sensing and computing unit, a cloud database and a system display and operation unit. By using intelligent and sensing technology, the system can sense, record and analyze the environment in which the vehicle is located, the vehicle itself and the dynamic and static behavior information of the elderly user, and explore the system form that meets the needs of the elderly users in combination with the cloud big data. The system can selectively adjust the structure and functional interface form of the car navigation system, including the form, quantity and layout of information on the interface, to reduce the cognitive load of the elderly users, thereby improving the efficiency and experience of the elderly drivers' operation and reducing the risk of traffic accidents.
