Existing screen adaptation usually adjusts the screen brightness according to the ambient light intensity. For example, in the Chinese patent "Method, Device, and Mobile Terminal for Controlling a Mobile Terminal Interface" with the application number 201210499473.1: The ambient light brightness is detected by a light sensor, and the display brightness of interface display elements is adjusted according to the ambient light brightness value. Users can still select the original user interface with fonts, icons, and backgrounds displayed under changing ambient light conditions, or select the display effect under a certain ambient light condition for use in other lights, improving the display performance of the mobile terminal and enhancing the user experience.

[0003] However, merely adjusting the interface display based on the environment cannot meet the reading needs of users of different ages. In actual applications and market research, it is found that the in-vehicle central control screen interface design of current new energy vehicle models generally has problems of insufficient adaptability to the elderly population and poor interaction usability, mainly manifested as follows: The color matching emphasizes aesthetics and sense of technology, ignoring the problems of reduced color vision and contrast sensitivity of the elderly population, making it difficult to read information.

[0008] In a further embodiment, the calculation formula for the initial color difference value is as follows:

[0009] In the formula, represents the initial color difference value; represents the CIELAB color value of the background color; represents the Lab value of the icon color; represents the color brightness, represents the value of the color in the red-green channel, represents the value of the color in the yellow-blue channel.

[0020] According to the age weight factor and the age correction factor, parameter optimization calculation is performed on the initial color difference value to highlight the recognition degree of the above-mentioned interaction elements on the interface background, and the target color difference value is obtained. Through the dual adjustment of the age weight factor and the age correction factor, the interface parameters (such as contrast) can be optimized more precisely according to the user needs of different age groups, and then the interface parameters are dynamically adjusted to adapt to the visual, cognitive and operation habits of different age groups, making the interface elements easier to distinguish and improving the information transmission efficiency.

The given embodiments are only for illustrative purposes and should not be construed as a limitation of the present invention. The drawings are only for reference and illustration and do not constitute a limitation on the scope of patent protection of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.

[0024] Embodiment 1 An interface adaptive display method provided by an embodiment of the present invention, as Figure 1 shown, in this embodiment, includes: S1. In response to an interface display instruction, detect interactive elements within the current interface, including: Obtain commands or instructions for controlling and managing the display of the user interface of the vehicle system. Based on biometric detection or seat detection, determine whether there is an interface interaction object. If so, in response to the interface display instruction, detect the interactive elements within the current interface. Among them, the interactive elements include at least one of text and pictures.

[0025] S2. Obtain the initial color difference values between each of the interactive elements and the interface background in the initial state, including: S21. Obtain the color parameters of each of the interactive elements in the initial state, and convert the color parameters of each of the interactive elements from the RGB color space to the CIELAB color space, including: Obtain the linear RGB of the RGB parameters of each of the interactive elements to remove gamma correction. Convert the linear RGB to the XYZ space through matrix multiplication. Use a reference white point for non-linear conversion to convert the XYZ space to the CIELAB color space.

[0026] S22. Obtain the color parameters of the interface background in the CIELAB color space, and obtain the color parameters of each of the interactive elements in the CIELAB color space. S23. Calculate the initial color difference values between the interactive elements and the interface background.

[0027] In this embodiment, the calculation formula for the initial color difference values is as follows:

[0028] In the formula, represents the initial color difference value; represents the CIELAB color value of the background color; represents the Lab value of the icon color; represents the color brightness, represents the value of the color in the red-green channel, represents the value of the color in the yellow-blue channel.

[0029] For example: The Lab value of the interface background is ( ) = (85, -2, -10), and the Lab value of the interactive element (taking the icon as an example) = (70, 10, 20), then:

[0030] S3. Collect the user information of the interface interaction object and identify the user information as an adaptive parameter, including: Collect an image through an image acquisition device, and use the user image of the interface interaction object as the user information; perform image recognition on one or more of the face, appearance, and clothing in the user image to determine the age information of the interface interaction object as an adaptive parameter; Alternatively, collect the user image of the interface interaction object through an image acquisition device, perform face recognition on the user image, determine the identity of the interface interaction object and obtain the user information carefully filled in by the user, and extract the age information therefrom as an adaptive parameter.

[0031] Among them, the image acquisition device includes, but is not limited to, the in-vehicle camera of the vehicle. The specific technical solution for judging age through face recognition is a conventional technology in this field and will not be elaborated in this embodiment.

[0032] S4. Perform parameter optimization calculation on the initial color difference value based on the adaptive parameter to highlight the recognition degree of the interaction element on the interface background, and obtain the target color difference value, including: S41. Obtain the age information in the adaptive parameter and obtain the age weight factor through the analytic hierarchy process. The age weight factor is a subjective coefficient. The older the elderly user is, the more obvious the decline in visual acuity is. Therefore, the older the age, the higher the value (range 0.7 - 1.0).

[0033] This embodiment gives a segmented interval of the age weight factor based on actual applications as follows:

[0034] S42. Obtain the age information in the adaptive parameter and confirm the age correction factor through the experimental test method. The age correction factor is a subjective coefficient. The older the age, the higher the value (range 0.6 - 1.0).

[0035] This embodiment gives a segmented interval of the age correction factor based on actual applications as follows:

[0036] n: Adjustment index. Determine the value of n through visual fatigue test (range 0.8 - 1.5).

[0037] In the formula, represents the age information. In other embodiments, the age weight factor and the age correction factor can also be finely segmented according to actual needs, and this embodiment does not make any restrictions.

[0038] For example, for a 70-year-old elderly user, Take 0.8, Take 0.8, and n takes 1.0, then:

[0039] S43. Optimize and calculate the parameters of the initial color difference value according to the age weight factor and the age correction factor to highlight the recognition degree of the interactive element on the interface background, and obtain the target color difference value.

[0040] In this embodiment, the calculation formula of the target color difference value is as follows:

[0041] In the formula, represents the optimized target color difference value; represents the initial color difference value; represents the age weight factor; represents the user age correction factor.

[0042] S5. Based on the target color difference value, keep the interface background unchanged, calculate the target color value corresponding to the interactive element and modify it.

[0043] In this embodiment, the calculation formula of the target color value of the interactive element is as follows:

[0044] Among them, the selection of the C value depends on the relative light and dark relationship between the background color and the element color, specifically as follows:

[0045] In the formula, represents the target color value; represents the optimized color difference value.

[0046] For example, in this embodiment, based on the above-mentioned 70-year-old elderly user, ( the L value of the color of the interactive element 70 < ( the L value of the color of the interface background 85), then C takes -1, then:

[0047] Therefore, the final target Lab value of the icon is (36.33, 10, 20).

[0048] That is, finally, modify the interactive element (icon) according to the target color value (36.33, 10, 20), and only change its color brightness from 70 to 36.33.

[0049] The order of the above steps S3 with respect to steps S1 and S2 is not limited in this embodiment and can be customized according to actual applications. For example, when the vehicle switches from the off state to the start state, the interface can be adaptively displayed regardless of whether step S3 is executed first or later. When the vehicle is temporarily parked, after detecting that the driver has left the seat through the seat sensor, step S3 can be preferentially executed. If the driver remains unchanged, the current interface parameters are maintained; if the driver changes, the adaptive display is adjusted.

[0050] Embodiment 2 The embodiment of the present invention further provides an electronic device, including: one or more processors; one or more memories; the one or more memories store one or more programs, and when the one or more programs are executed by the one or more processors, the electronic device executes the interface adaptive display method as described in Embodiment 1 above.

[0051] The beneficial effects of the embodiment of the present invention are as follows: During the vehicle usage process, when it is recognized that the vehicle is enabled or the user is changed, the user image of the current interface interaction object is collected in real time through the image acquisition device as user information, and then the age information of the interface interaction object is used as an adaptive parameter to automatically perform personalized adaptive adjustment on the interface, adapting to user needs, improving the efficiency of obtaining interface information, reducing operation difficulties, and effectively enhancing user satisfaction.

[0052] The initial color difference value is optimized and calculated according to the age weight factor and the age correction factor to highlight the recognition of the interaction elements on the interface background, and the target color difference value is obtained. Through the dual adjustment of the age weight factor and the age correction factor, the interface parameters (such as contrast) can be more accurately optimized according to the needs of users of different age groups, and then the interface parameters are dynamically adjusted to adapt to the visual, cognitive, and operation habits of different age groups, making the interface elements easier to distinguish and improving the information transmission efficiency.

[0053] During the process of adjusting the interface parameters, first convert the color parameters of each interaction element from the RGB color space to the CIELAB color space, and then, based on different background colors, only adjust the brightness of the icons without changing the values of the a and b channels. On the premise of maintaining the color coordination of the interface and the stability of the overall color scheme, the recognition of the interaction interface by elderly users is enhanced. The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
