The card-style desktop uses a segmented program card layout, with each program card corresponding to an independent function. Program cards include one or more types, such as navigation program cards, music program cards, air conditioning program cards, and entertainment program cards. Some card-style desktops support adding, deleting, and moving one or more program cards, making them easy to use and adaptable to different user habits, flexibly matching functional needs in different scenarios. The immersive entertainment desktop uses high-definition wallpapers or animated... Based on a static background, it integrates various entertainment functions including video playback, games, music, and screen mirroring, minimizing complex operation elements and enhancing the comfort and enjoyment of the ride. The simple wallpaper desktop mainly uses static or dynamic wallpapers, retaining a few function entries and supporting custom wallpaper changes to reduce interface clutter and meet the personalized aesthetic needs of drivers and passengers. The interactive desktop supports cross-screen content flow, breaking the functional limitations of a single screen, realizing multi-screen information sharing and collaborative control, adapting to the usage needs of different positions in the car, making interaction more flexible and smooth, and enhancing the overall intelligent experience of the cabin. The quick control desktop integrates high-frequency quick functions, with the interface mainly featuring large icons and simple buttons, some of which support voice linkage control, centralizing scattered control functions and shortening the operation path.

[0075] Icons: Icons are small, visual identifiers on the desktop that represent applications. They are typically presented as simple graphics (with a minimal text name) and serve as quick access points to launch applications. They are small in size, have fixed styles or support customization, and are associated with the launch command of the corresponding application. Icons allow users to intuitively distinguish between different applications, and by clicking an icon, they can quickly launch the application without having to search through complex menus, simplifying the operation path.

[0076] Application Cards: Application cards are visual interactive modules associated with a specified application. Application cards include one or more of the following characteristics: • Dynamically display real-time information for a specified application; • Integrates one or more entry points for operations / functions, enabling multiple functions without launching the full interface of the application; • At least one of the following: size, position, and display format can be flexibly adjusted by the user or system.

[0077] Unlike icons, which serve only as static launch points, application cards carry dynamic content for a single application and / or continuously update application data or information (such as navigation routes, music playback progress, and message notifications). Application cards also differ from feature-aggregated folders, which manage multiple application entry points; application cards do not collect or manage other applications or cards. Application cards are interactive cards or controls used to display real-time information about the application and implement all or part of the application's functions. They have real-time information preview capabilities and can be dynamically adjusted in real time.

[0078] Optionally, on an in-vehicle display, the application card may appear as a navigation preview, music playback controls, or an air conditioning settings panel; in the virtual space of virtual reality (VR) or augmented reality (AR) glasses, the application card may appear as a floating, spatially positioned 3D information panel; on a head-up display (HUD), it can be integrated with the real field of view, displaying key navigation or safety prompts as a transparent layer. The application card can be presented and interacted with as a unified information module across device forms (such as in-vehicle screens, VR or AR spaces, and HUDs).

[0079] Each application card is associated with an application, and the visual presentation of the application card includes at least one of the following: an information display area for continuously updating and displaying data or information from the associated application, an interactive operation area for integrating one or more functions for the application, and an identification area for displaying the application name or icon.

[0080] Secondly, the relevant content involved in this application will be introduced.

[0081] In related technologies, when operating the central control screen, users can add program cards to the display desktop by long-pressing any program card on the display desktop to enter the edit state and display a list of program cards that can be added; or an add button can be displayed, and clicking the button can jump to the program card library and click the program card that you want to add.

[0082] When deleting an application card on the central control screen's display desktop, users need to long-press the application card to enter edit mode. A red delete button or delete icon will appear on the application card. Click the icon to delete.

[0083] To address the issue of cumbersome operation steps in related technologies, this application adopts a method of continuously switching between display desktop and desktop editing state, which improves the correlation between various functional areas of the system, enhances operational efficiency and ease of use, and reduces the failure rate of functional operations.

[0084] Figure 2A flowchart illustrating a human-computer interaction method for a cockpit display screen provided in an exemplary embodiment of this application is shown. The method is performed by a display device and includes: Step 210: Display the first layout of the first desktop, which includes a first area and multiple controls, including the first control among the multiple controls.

[0085] The first desktop is a desktop with program cards on the screen of the in-vehicle display device, also known as a card-style desktop.

[0086] The first desktop can be deployed on one or more of various in-vehicle screens, including the central control screen, passenger entertainment screen, rear entertainment screen, sliding screen, magic control screen, and central touch screen.

[0087] On in-vehicle display screens, a card-based desktop is a main screen interface or system default user interface adapted to in-vehicle driving scenarios, using application cards as the primary interaction module. The card-based desktop transforms individual in-vehicle applications or functions into independent visual application cards, presented on the screen through a segmented layout. It supports customizing the position, combination, and addition / removal of application cards, directly displaying dynamic information about the corresponding functions of the application, and providing entry points for one or more operations / functions within the application card. For example, switching tracks in a music application card or viewing the remaining trip in a navigation application card can be done without entering the full application interface, thereby improving the convenience of operation and the intuitiveness of information acquisition during driving, and meeting the safety interaction needs while driving.

[0088] For example, such as Figure 3 As shown, the first control 30 is located in the lower left corner of the first desktop and is used to enable the first desktop to enter an editable state and / or change the layout of the first desktop.

[0089] In some embodiments, the upper area of ​​the first desktop is a vehicle status information bar, which displays the current system time status information, allowing users to quickly obtain the vehicle's operating parameters.

[0090] In some embodiments, the lower area of ​​the first desktop is an application shortcut bar containing app thumbnails of multiple applications. The layout of this area is fixed, and the apps displayed below are not necessarily related to the application cards of the applications currently displayed on the first desktop. The content displayed does not change with desktop switching. That is, during the process of switching from the first desktop to the second desktop, the third desktop, or other desktops, the app thumbnails in this shortcut bar remain fixed and do not change with the switching process. Users can quickly launch the corresponding application by clicking the thumbnail without having to go into the application list to find it.

[0091] For example, such as Figure 3As shown, the first layout is displayed. At this time, the first layout only has a first area and multiple controls. The first area includes program cards of n applications, and the multiple controls include the first control.

[0092] Step 220: In response to the first trigger operation on the first control, switch the first layout to the second layout. The second layout includes a first area and a second area. The first area is used to display the program cards of n applications, and the second area is used to display the icons of m applications.

[0093] In some embodiments, when the first desktop is in the second layout, the first desktop is in an editable state. The editable state of the first desktop is a state in which program cards of n applications switch between a currently displayed state and a canceled display state, and / or a state in which icons of m applications switch between a first state and a second state. It can also be understood as a state in which a delete button appears in the upper right corner of the program cards of n applications in the first area, and at the same time, a first identifier appears in the upper right corner of the icons of n applications in the second area.

[0094] like Figure 4 As shown, the first desktop includes a first area 410 and a second area 420. The first area 410 is located above or below the second area 420. The first area 410 is used to display program cards of n applications, and the second area 420 is used to display icons of m applications. The types of the n applications and the m applications may overlap or not overlap.

[0095] The types of the n and / or m applications include: navigation and positioning applications, which meet the route guidance needs while driving; audio-visual entertainment applications, which provide users with auditory and visual entertainment; vehicle control and diagnostic applications, which directly connect to vehicle hardware to monitor vehicle conditions and ensure normal vehicle operation; interconnection and interaction applications, which break down device barriers and enable the vehicle to interact with other devices and scenarios, including mobile phone-vehicle interconnection programs and / or vehicle-home interconnection programs; system tools and personalization applications, which provide download and management of various applications, optimize the vehicle user experience, and / or enable personalized customization; and communication and collaboration applications, which support voice-controlled calling functions and / or synchronize mobile phone contacts and call logs for seamless integration.

[0096] In some embodiments, the second area is used to display icons of m applications, including: displaying icons of all or some applications in the system in the second area according to user usage frequency or system preset order.

[0097] Optionally, in the second area, icons corresponding to one or more program cards on the first desktop are displayed according to the user's usage frequency or a system preset order. For example, there are three desktops, each displaying three program cards, and nine icons corresponding to these nine program cards are displayed in the second area.

[0098] Optionally, the icon order can be preset based on driving operation convenience. Alternatively, the icon order can be preset by taking into account the driver's operating posture and touch range, and / or by following the relevance of functions and the logic of usage scenarios.

[0099] In some embodiments, the order of icons and the content displayed are not fixed, but dynamically adapted based on the user's usage scenario and operating habits.

[0100] Step 230: Control the linkage between the first application card and the first icon of the first application.

[0101] Wherein, the program cards of n applications include the first program card; and / or, the icons of m applications include the first icon, where n and m are both positive integers.

[0102] In some embodiments, the first program card is displayed in the first area, and the first icon is displayed in the second area, or is folded under the second area.

[0103] The linkage between the first program card and the first icon refers to the synchronized response between them in terms of function, information, and operation, achieving interoperability and information sharing to meet the safety and convenience requirements of in-vehicle scenarios. The linkage includes bidirectional synchronization of operations; when an operation is performed on the first program card or the first icon, a corresponding response will appear on the other side; and real-time synchronized display of information, where the first program card will synchronize the dynamic information of the application associated with its corresponding first icon in real time, allowing users to intuitively access content without entering the application.

[0104] In this application, the linkage between the first program card and the first icon includes changing the display state of the first program card or performing an operation on the first program card, and the display state of the first icon performing a corresponding response feedback, and / or changing the display state of the first icon or performing an operation on the first icon, and the display state of the first program card performing a corresponding response feedback.

[0105] In this application, the display state of the first program card includes a displaying state and a canceled display state, and the display state of the first icon includes a first state and a second state.

[0106] The states are as follows: the first program card is displayed on the first desktop; the state of being canceled is that the first program card is not displayed on the first desktop; the first state includes the first icon displaying the first identifier; and the second state includes the first icon not displaying the first identifier.

[0107] Optionally, the first identifier is a checkmark displayed in the upper right corner of the first icon. This application does not limit the implementation of the first identifier, as long as it supports distinguishing the two states of the first icon.

[0108] In some embodiments, such as Figure 4 As shown, the operation performed on the first icon "Application 4" includes a click operation. The click operation can be implemented as follows: after the user touches the first icon "Application 4" on the screen with their finger and immediately releases it, in response to the click operation on the first icon "Application 4", the display state of the first icon "Application 4" is changed, and according to the display state of the first icon "Application 4", the corresponding operation is performed on the first program card "Program Card 4".

[0109] For example, when a user touches the first icon "App 4" on the screen and immediately releases their finger, in response to the click operation on the first icon "App 4", the check mark in the upper right corner of the first icon "App 4" disappears, and the first application card "Application Card 4" is deleted.

[0110] Optionally, if the in-vehicle display supports floating touch, the click operation can also be implemented as follows: the user does not touch the screen, but points to the location of the first icon "Application 4" on the screen with their finger. When the first icon "Application 4" on the screen appears as a selected icon, the user slightly shakes their finger to change the display state of the first icon "Application 4". Based on the display state of the first icon "Application 4", the user performs the corresponding operation on the first program card "Program Card 4".

[0111] For example, when the in-vehicle display supports floating touch, the user can point to the location of the first icon "Application 4" on the screen without touching it. When the first icon "Application 4" appears with a selection mark, the user can slightly shake their finger, and the check mark in the upper right corner of the first icon "Application 4" will disappear, thus deleting the first program card "Program Card 4".

[0112] There are no restrictions on how users touch the screen or how they point at it.

[0113] In some embodiments, such as Figure 5As shown, the operations performed on the first program card "program card 4" include a click operation. The click operation can be implemented as follows: after the user touches a designated position on the first program card "program card 4" on the screen with their finger, they immediately release their finger. In response to the click operation on the first program card "program card 4", the display state of the first program card "program card 4" is changed, and according to the display state of the first program card, the corresponding operation is performed on the first icon.

[0114] For example, when a user touches the delete button on the first application card "Application Card 4" and immediately releases their finger, the first application card "Application Card 4" is deleted in response to the click operation on the first application card "Application Card 4", and the check mark in the upper right corner of the first icon "Application 4" disappears.

[0115] The method of deleting the first program card "Program Card 4" is not limited.

[0116] Optionally, if the in-vehicle display supports floating touch, the click operation can also be implemented as follows: the user does not touch the screen, but points to a designated location on the first program card on the screen with their finger. When a selection mark appears at the designated location on the first program card, the user slightly shakes their finger to change the display state of the first program card. Based on the display state of the first program card, the user performs the corresponding operation on the first icon. There are no restrictions on the way the user touches the screen or the way the user points to the screen.

[0117] For example, when the in-vehicle display supports floating touch, the user does not touch the screen. The user points to the delete key on the first program card with their finger. When the delete key on the first program card is selected, the user shakes their finger slightly to delete the first program card "Program Card 4". The check mark in the upper right corner of the first icon "Application 4" disappears.

[0118] In summary, the first layout of the first desktop is switched to a second layout, which includes a first area and a second area. The first area displays program cards for n applications, and the second area displays icons for m applications. The system controls the linkage between the first program card and the first icon of the first application. Without leaving the first desktop, program cards of the first application can be automatically added or deleted in response to trigger operations on the first icon. This reduces the user's extra operations, solves the problem of cumbersome and inefficient operation caused by multi-level human-computer interaction, improves the correlation between various functional areas of the system, enhances operational efficiency and ease of use, and reduces the failure rate of functional operations.

[0119] 1. In response to a first trigger operation on the first control, switch the first layout of the first desktop to the second layout.

[0120] Figure 6 A flowchart illustrating a human-computer interaction method for a cockpit display screen provided in an exemplary embodiment of this application is shown.

[0121] In some embodiments, for step 220: such as Figure 6 As shown, in response to a first trigger operation on the first control, switching the first layout to the second layout includes: Step 221: In response to a first trigger operation on the first control, shift the first region upward and display the second region below the first region; or shift the first region downward and display the second region above the first region.

[0122] In some embodiments, in response to a first trigger operation on a first control, the size of the application cards of n applications in the first region is proportionally reduced from a first size to a second size that does not overlap with the second region.

[0123] In some embodiments, in response to a first trigger operation on a first control, q application components, where q is a positive integer, are displayed above a first area.

[0124] like Figure 7 As shown, in response to a first trigger operation on the first control, the layout of the first desktop is changed by shifting the first area upwards and simultaneously reducing the size of the application cards of n applications in the first area to display the second area 420. The application cards of m applications are displayed in the second area. For example, the second area 420 can be expanded to display all applications in the system that support displaying application cards on the first desktop, and q application widgets are displayed above the application cards of the n applications.

[0125] 2. In response to a second trigger operation on the first control, switch the second layout of the first desktop to the first layout.

[0126] In some embodiments, such as Figure 8 As shown, in response to a second trigger operation on the first control, switching the second layout to the first layout includes: Step 240: In response to the second trigger operation on the first control, switch the second layout to the first layout.

[0127] In some embodiments, in response to a second triggering operation on a first control, the second layout is switched to the first layout.

[0128] In some embodiments, in response to a second trigger operation on the first control, the second area is switched to a de-display state.

[0129] In some embodiments, the size of the application cards of n applications in the second layout is a second size, and in response to a second trigger operation on the first control, the size of the application cards of the n applications in the first area is restored from the second size to the first size.

[0130] In some embodiments, the second layout also displays q application components, and in response to a second trigger operation on the first control, the display of the q application components is canceled.

[0131] For example, such as Figure 9 As shown, in response to a second click operation on the first control, such as Figure 10 As shown, the second area is switched from being displayed to being undisplayed, the size of n application cards is restored from the second size to the first size, and the widgets of q applications are undisplayed.

[0132] For step 230: it includes one or more of the following steps: • In response to a trigger operation on the first program card, change the display state of the first icon.

[0133] • When the display state of the first program card changes, change the display state of the first icon.

[0134] • In response to a trigger action on the first icon, change the display state of the first program card.

[0135] • When the display state of the first icon changes, change the display state of the first program card.

[0136] The following describes an exemplary embodiment of the human-computer interaction method for the cockpit display screen described above.

[0137] In some embodiments, when the display state of the first application card of the first application changes, and / or, in response to a triggering operation on a second control on the first application card, the display state of the first icon of the first application is changed.

[0138] In some embodiments, when the display state of the first icon of the first application changes, and / or, in response to a trigger operation on the first icon, the display state of the first application card of the first application is changed.

[0139] 3. In response to a trigger operation on the second control on the first program card, change the display state of the first icon.

[0140] In some embodiments, switching the first layout to the second layout in response to a first trigger operation on the first control further includes: displaying the second control on the application card of at least one of the application cards of n applications in the first region in response to the first trigger operation on the first control.

[0141] Figure 11 A flowchart illustrating a human-computer interaction method for a cockpit display screen provided in an exemplary embodiment of this application is shown.

[0142] In some embodiments, such as Figure 11 As shown, in response to a trigger operation on a second control on a first application card, changing the display state of a first icon of the first application includes: Step 231: In response to a third trigger operation on the second control, switch the first application card of the first application from the currently displayed state to the undisplayed state, and switch the display state of the first icon from the first state to the second state.

[0143] The first state indicates that the first program card is in the display state, and the second state indicates that the first program card is in the cancel display state.

[0144] In this application, as Figure 12 As shown, the third triggering operation includes a third click operation. The third click operation can be implemented as follows: the user touches a designated location on the first application card "Application Card 4" on the screen and immediately releases their finger. For example, the user touches the delete button in the upper right corner of the first application card "Application Card 4" and immediately releases their finger. In response to the click operation on the first application card, the first application card is deleted, and the display state of the first icon "Application 4" is changed accordingly. For example, the check mark in the upper right corner of the first icon "Application 4" is deleted.

[0145] Optionally, if the in-vehicle display supports floating touch, the third click operation can also be implemented as follows: the user does not touch the screen, but points to a specific location on the first program card "Program Card 4" on the screen with their finger. For example, the user points to the delete key on the first program card "Program Card 4". When the delete key on the first program card "Program Card 4" shows a selection mark, the user slightly shakes their finger to delete the first program card, which changes the display state of the first icon accordingly. For example, the check mark in the upper right corner of the first icon is deleted.

[0146] There are no restrictions on how users touch the screen or how they point at it.

[0147] In some embodiments, in response to a third trigger operation on a second control on a first application card, switching the first application card of the first application from a currently displayed state to a de-displayed state, and switching the display state of the first icon from a first state to a second state, includes: In response to a third click operation on the second control on the first program card, the size of the first program card in the display state is proportionally reduced until the first program card is de-displayed, and the display state of the first icon is switched from the first state to the second state.

[0148] The first state includes the first icon displaying the first identifier in the upper right corner, and the second state includes the first icon not displaying the first identifier in the upper right corner.

[0149] like Figure 13 As shown, in response to a click operation on a specified location of the first program card "Program Card 4", the first program card "Program Card 4" is deleted, and the size of the first program card "Program Card 4" is reduced proportionally, such as... Figure 14 As shown, this continues until the first program card "Program Card 4" completely disappears. The specified location of the first program card "Program Card 4" includes the location of the delete key on the first program card "Program Card 4". For example, the delete key on the first program card "Program Card 4" is located in the upper right corner of the first program card.

[0150] For example, a third trigger operation for a first program card includes a first swipe operation for the first program card.

[0151] The first swipe operation includes swiping the first program card up or down, with the swipe distance meeting a first threshold, deleting the first program card, and putting the first program card in a canceled display state. This application does not limit the implementation method of the third trigger operation.

[0152] 4. When the display state of the first program card changes, change the display state of the first icon.

[0153] Figure 15 A flowchart illustrating a human-computer interaction method for a cockpit display screen provided in an exemplary embodiment of this application is shown.

[0154] In some embodiments, when the display state of the first application card of the first application changes, changing the display state of the first icon of the first application includes: Step 232: When the running state of the first application meets the first triggering condition, switch the first program card of the first application from the currently displayed state to the canceled display state, and switch the display state of the first icon from the first state to the second state.

[0155] The first state indicates that the first program card is in the display state, and the second state indicates that the first program card is in the cancel display state.

[0156] In some embodiments, when the running state of the first application meets a first triggering condition, switching the first application card of the first application from a currently displayed state to a canceled display state, and switching the display state of the first icon from a first state to a second state, includes: If the current working state does not support the first application card of the first application being displayed, the size of the first application card in the display state will be reduced proportionally until the first application card of the first application is de-displayed, and the display state of the first icon will be switched from the first state to the second state.

[0157] The first state includes the first icon displaying the first identifier in the upper right corner, and the second state includes the first icon not displaying the first identifier in the upper right corner.

[0158] For example, such as Figure 13 and Figure 14 As shown, when the first application card "Application Card 4" is not displayed in the current working state, the size of the first application card "Application Card 4" is proportionally reduced until the first application card "Application Card 4" is de-displayed, and the display state of the first icon "Application 4" is switched from the first state to the second state.

[0159] The first state includes a checkmark displayed in the upper right corner of the first icon, and the second state includes no checkmark displayed in the upper right corner of the first icon.

[0160] In some embodiments, the first triggering condition includes at least one of the following: the first application ends video playback; the first application exits navigation mode; the first application ends real-time call; the state change of the first application from running in the foreground to running in the background meets a preset condition.

[0161] In some embodiments, the first triggering condition includes the first application ending video playback. That is, when the system detects that the first application has switched from video playback state to non-video playback state, it determines that the first application card does not need to be displayed on the first desktop. Keeping the first application card displayed on the first desktop may cause space redundancy.

[0162] In some embodiments, the first triggering condition includes the first application ending a real-time call. That is, when the first application (such as a communication application) ends a voice or video call or the voice or video call is hung up, the system determines that it is not necessary to view communication-related information or perform communication-related operations at any time, and the first application card does not need to be displayed on the first desktop.

[0163] In some embodiments, the first triggering condition includes a state change where the first application switches from running in the foreground to running in the background, which satisfies a preset condition. This preset condition includes, but is not limited to, at least one of the following: the user actively switches to another application, or the current application does not require a high-priority task to be continuously displayed in the foreground.

[0164] In this application, the first icon has different first and second states to distinguish whether the first application corresponding to the first icon is displayed on the first desktop. When the first application card is not displayed on the first desktop, the first icon is in the first state; when the first application card is displayed on the first desktop, the first icon is in the second state.

[0165] This application does not limit the specific implementation of distinguishing between the first state and the second state. For example, the first icon being in the first state includes the display of a first identifier in the upper right corner of the first icon, and the first icon being in the second state includes the first icon not displaying the first identifier in the upper right corner of the first icon. The first identifier is a checkmark displayed in the upper right corner of the first icon.

[0166] In embodiments of “3. In response to a trigger operation on a second control on a first program card, change the display state of the first icon.” and / or “4. When the display state of the first program card changes, change the display state of the first icon.”, when the first program card is in a de-display state, the second program card adjacent to the first program card moves to the original position of the first program card.

[0167] The original location of the second program card is on the first desktop or on a second desktop adjacent to the first desktop.

[0168] 5. In response to a trigger operation on the first icon, change the display state of the first program card.

[0169] Figure 16 A flowchart illustrating a human-computer interaction method for a cockpit display screen provided in an exemplary embodiment of this application is shown.

[0170] In some embodiments, in response to a trigger operation on a first icon, changing the display state of a first application card of a first application includes: Step 233: Determine whether the first icon is in the first state.

[0171] If the first icon is in the first state, proceed to step 234; if the first icon is not in the first state, proceed to step 235. Step 234: In response to the fourth trigger operation on the first icon, switch the display state of the first icon from the first state to the second state, and switch the first application card of the first application from the currently displayed state to the canceled display state; Step 235: In response to the fifth trigger operation on the first icon, switch the display state of the first icon from the second state to the first state, and restore the first application card of the first application from the canceled display state to the displayed state.

[0172] In some embodiments, in response to a fourth trigger operation on the first icon, switching the display state of the first icon from a first state to a second state, and switching the first application card of the first application from a currently displayed state to a canceled display state, includes: In response to a fourth click on the first icon, such as Figure 13 As shown, the display state of the first icon is switched from the first state to the second state; and the size of the first program card in the currently displayed state is proportionally reduced until the first program card is in the undisplayed state; The first state includes the first icon displaying the first identifier in the upper right corner, and the second state includes the first icon not displaying the first identifier in the upper right corner.

[0173] For example, such as Figure 17 As shown, in response to the fourth trigger operation for the first icon "Application 4", the display state of the first icon "Application 4" is switched from the first state to the second state, and the size of the first application card "Application Card 4" which is currently being displayed is proportionally reduced until the first application card "Application Card 4" of the first application is in the undisplayed state.

[0174] The first state includes a checkmark displayed in the upper right corner of the first icon, and the second state includes no checkmark displayed in the upper right corner of the first icon.

[0175] In some embodiments, in response to a fifth trigger operation on the first icon, switching the display state of the first icon from a second state to a first state, and restoring the first application card of the first application from a canceled display state to a currently displayed state, includes: In response to the fifth click on the first icon, the display state of the first icon is switched from the second state to the first state, and the first application card is added to the far right of the first desktop. The first state includes the first icon displaying the first identifier in the upper right corner, and the second state includes the first icon not displaying the first identifier in the upper right corner.

[0176] For example, such as Figure 18 As shown, in response to the fifth triggered action for the first icon "Application 4", as Figure 19 As shown, the display state of the first icon "Application 4" is switched from the second state to the first state, and the first program card "Program Card 4", which is currently being displayed, is added to the far right of the first desktop.

[0177] The first state includes a checkmark displayed in the upper right corner of the first icon, and the second state includes no checkmark displayed in the upper right corner of the first icon.

[0178] In some embodiments, the fourth triggering operation includes a fourth click operation, and the fourth triggering operation includes a fifth click operation.

[0179] The fourth click operation can be implemented as follows: after the user touches the first icon on the screen in the first state with their finger and immediately releases their finger, in response to the click operation on the first icon in the first state, the display state of the first icon is switched from the first state to the second state, and the first program card of the first application corresponding to the first icon is deleted on the first area of ​​the first desktop. Optionally, the fourth click operation can also be implemented as follows: without touching the screen, the user points to the location of the first icon in the first state on the screen with their finger. When the first icon in the first state on the screen appears as a selected icon, the user slightly shakes their finger to switch the display state of the first icon from the first state to the second state, and deletes the first program card of the first application corresponding to the first icon on the first area of ​​the first desktop. There are no restrictions on the way the user touches the screen or the way the user points to the screen.

[0180] The fifth click operation can be implemented as follows: after the user touches the first icon on the screen in the second state with their finger and immediately releases their finger, in response to the click operation on the first icon in the second state, the display state of the first icon is switched from the second state to the first state, and the first program card of the first application corresponding to the first icon is added to the first area on the first desktop. Optionally, the fifth click operation can also be implemented as follows: without touching the screen, the user points to the location of the first icon in the second state on the screen with their finger. When the first icon in the second state on the screen appears as a selected icon, the user slightly shakes their finger to switch the display state of the first icon from the second state to the first state, and adds the first application card of the first application corresponding to the first icon to the first area on the first desktop. There are no restrictions on the way the user touches the screen or the way the user points to the screen.

[0181] This application does not limit the specific implementation method of adding the first program card. For example, in response to the fifth click operation of the first icon, the first program card slides out from top to bottom or from bottom to top, or the size of the first program card gradually increases and is displayed in the first area of ​​the first desktop.

[0182] 6. The display state of the first icon changes, thus changing the display state of the first program card.

[0183] Figure 20 A flowchart illustrating a human-computer interaction method for a cockpit display screen provided in an exemplary embodiment of this application is shown.

[0184] In some embodiments, when the display state of the first icon of the first application changes, changing the display state of the first application card of the first application includes: Step 233: Determine whether the first icon is in the first state.

[0185] If the first icon is in the first state, proceed to step 236; if the first icon is not in the first state, proceed to step 237.

[0186] Step 236: If the running state of the first application meets the second triggering condition, switch the display state of the first icon from the first state to the second state, and switch the first application card of the first application from the currently displayed state to the canceled display state; or, Step 237: When the running state of the first application meets the third triggering condition, switch the display state of the first icon from the second state to the first state, and switch the first program card of the first application from the canceled display state to the displaying state.

[0187] The first state indicates that the first program card is in the display state, and the second state indicates that the first program card is in the cancel display state.

[0188] In some embodiments, when the running state of the first application meets the second triggering condition, switching the display state of the first icon from the first state to the second state, and switching the first application card of the first application from the currently displayed state to the canceled display state, includes: If the current working state does not support the first icon to be displayed in the first state, switch the display state of the first icon from the first state to the second state, and proportionally reduce the size of the first program card that is currently being displayed until the first program card is in the undisplayed state.

[0189] The first state includes the first icon displaying the first identifier in the upper right corner, and the second state includes the first icon not displaying the first identifier in the upper right corner.

[0190] For example, if the current working state does not support the display state of the first icon being in the first state, the display state of the first icon "Application 4" is switched from the first state to the second state, and the size of the first application card "Application Card 4" which is currently being displayed is proportionally reduced until the first application card "Application Card 4" of the first application is in the undisplayed state.

[0191] The first state includes a checkmark displayed in the upper right corner of the first icon, and the second state includes no checkmark displayed in the upper right corner of the first icon.

[0192] In some embodiments, the second triggering condition includes at least one of the following: the first application ends video playback; the first application exits navigation mode; the first application ends real-time call; the state change of the first application from running in the foreground to running in the background meets a preset condition.

[0193] In some embodiments, the second triggering condition includes the first application ending video playback. That is, when the system detects that the first application has switched from video playback state to non-video playback state, it determines that the first application card does not need to be displayed on the first desktop. Keeping the first application card displayed on the first desktop may cause space redundancy.

[0194] In some embodiments, the second triggering condition includes the first application ending a real-time call. That is, when the first application (such as a communication application) ends a voice or video call or the voice or video call is hung up, the system determines that it is not necessary to view communication-related information or perform communication-related operations at any time, and the first application card does not need to be displayed on the first desktop.

[0195] In some embodiments, the second triggering condition includes a state change where the first application switches from running in the foreground to running in the background, which satisfies a preset condition. This preset condition includes, but is not limited to, at least one of the following: the user actively switches to another application, or the current application does not require a high-priority task to be continuously displayed in the foreground.

[0196] When the display state of the first icon changes, the display state of the first program card will automatically change, which can reduce visual interference, reduce driving safety risks, automatically delete invalid and low-frequency program cards, reduce redundant information on the screen, make important function program cards stand out, release system resources, improve the smoothness of vehicle system operation, and improve interaction efficiency.

[0197] In some embodiments, when the running state of the first application meets a third triggering condition, switching the display state of the first icon from the second state to the first state, and switching the first application card of the first application from the canceled display state to the currently displayed state, includes: If the current working state does not support the display state of the first icon being in the second state, switch the display state of the first icon from the second state to the first state, and add the first program card to the far right of the first desktop. The first state includes the first icon displaying the first identifier in the upper right corner, and the second state includes the first icon not displaying the first identifier in the upper right corner.

[0198] For example, if the current working state does not support the display state of the first icon being in the second state, the display state of the first icon "Application 4" is switched from the second state to the first state, and the first program card "Program Card 4" which is currently being displayed is added to the far right of the first desktop.

[0199] The first state includes a checkmark displayed in the upper right corner of the first icon, and the second state includes no checkmark displayed in the upper right corner of the first icon.

[0200] In some embodiments, the third triggering condition includes the first application playing a video. That is, when the system detects that the first application has switched from a non-video playback state to a video playback state, it determines that the first application card needs to be added to the first desktop so that video-related information and / or the first application operation entry can be quickly found later.

[0201] In some embodiments, the third triggering condition includes the first application entering navigation mode. That is, when the first application switches from route planning and location search to real-time navigation guidance mode, the system determines that the first application card needs to be added to the first desktop so that the route display, intersection magnification map and traffic information, and / or the first application operation entry can be quickly found later.

[0202] In some embodiments, the third triggering condition includes the first application receiving a real-time call request. That is, when the first application (such as a communication application) receives a call request for a voice or video call, the system determines that the first application card needs to be added to the first desktop so that the caller's information can be quickly found later, and / or the first application's operation entry point.

[0203] In some embodiments, the third triggering condition includes a state change where the first application switches from running in the background to running in the foreground that meets a preset condition. This preset condition includes, but is not limited to, at least one of the following: the application is activated by an important notification; the application is launched directly by the user via an icon or other shortcut; or the task being performed in the background by the application has a high priority and requires foreground monitoring.

[0204] In this application, in response to a trigger operation on the first icon, the display state of the first program card is changed. During driving, without leaving the first desktop, the first program card can be added to the first desktop simply by performing a fifth trigger operation on the first icon or changing the display state of the first icon. This shortens the operation time, avoids reduced efficiency due to hidden multi-level menus, reduces driving safety risks, reduces system response pressure, and minimizes the impact of lag.

[0205] In this application, any one of the following can be implemented individually as an embodiment of a human-computer interaction method for a cockpit display screen; or, the above embodiments can be combined to jointly implement an embodiment of a human-computer interaction method for a cockpit display screen.

[0206] In this application, all names of modes, areas, interfaces, and related prompts are examples. This application uses the desktops of various screens in a vehicle cabin as examples for illustration. The application scenarios of this application are not limited to the field of intelligent vehicles.

[0207] In summary, the first layout of the first desktop is switched to a second layout, which includes a first area and a second area. The first area displays program cards for n applications, and the second area displays icons for m applications. The system controls the linkage between the first program card and the first icon of the first application. Without leaving the first desktop, program cards of the first application can be automatically added or deleted in response to trigger operations on the first icon. This reduces the user's extra operations, solves the problem of cumbersome and inefficient operation caused by multi-level human-computer interaction, improves the correlation between various functional areas of the system, enhances operational efficiency and ease of use, and reduces the failure rate of functional operations.

[0208] Figure 21 A flowchart illustrating a human-computer interaction method for a cockpit display screen according to an exemplary embodiment of this application is shown. The steps of the method are as follows: Step 1: Display the first layout of the first desktop. The first layout includes a first area and multiple controls, including the first control.

[0209] In some embodiments, the first control is located in the lower left corner of the first desktop and is used to enable entry into the editable state of the first desktop and / or change the layout of the first desktop.

[0210] In some embodiments, the editable state of the first desktop is a state in which program cards of n applications switch between a currently displayed state and a canceled display state, and / or a state in which icons of m applications switch between a first state and a second state. It can also be understood as a state in which a delete button appears in the upper right corner of the program cards of n applications in the first area, and at the same time, a first identifier appears in the upper right corner of the icons of n applications in the second area.

[0211] Step 2: In response to the first trigger operation on the first control, switch the first layout to the second layout.

[0212] In some embodiments, such as Figure 3 As shown, the first desktop is displayed. At this time, the first desktop only has a first area and multiple controls. The first area includes application cards for n applications, and the multiple controls include the first control. Figure 3 As shown, in response to a first click operation on the first control, the layout of the first desktop is changed by shifting the first area upwards and simultaneously reducing the size of the application cards of n applications in the first area to display a second area. In the second area, application cards of m applications are displayed. For example, the second area can be expanded to display all applications in the system that support displaying application cards on the first desktop, and widgets of q applications are displayed above the application cards of the n applications.

[0213] For a detailed description of the first trigger operation, please refer to "1. In response to the first trigger operation on the first control, switch the first layout of the first desktop to the second layout." It will not be repeated here.

[0214] Step 3: Determine whether to execute the third trigger operation on the second control on the first program card.

[0215] If a third trigger operation is performed on the second control on the first program card, proceed to step 4; if no third trigger operation is performed on the first program card, proceed to step 5.

[0216] For a detailed description of the third trigger operation, please refer to "3. In response to the trigger operation of the second control on the first program card, change the display state of the first icon." It will not be repeated here.

[0217] Step 4: Switch the first application card of the first application from the currently displayed state to the undisplayed state, and switch the display state of the first icon from the first state to the second state.

[0218] For details regarding the switching of the first application card from the currently displayed state to the undisplayed state, and the switching of the display state of the first icon from the first state to the second state, please refer to "3. In response to a trigger operation on the second control on the first application card, change the display state of the first icon." These details will not be repeated here.

[0219] Step 5: Determine whether the first program card meets the first trigger condition.

[0220] If the first program card meets the first trigger condition, proceed to step 4; if the first program card does not meet the first trigger condition, proceed to step 6.

[0221] For a detailed description of the first triggering condition, please refer to "4. When the display state of the first program card changes, change the display state of the first icon." It will not be repeated here.

[0222] Step 6: Determine if the first icon is in the first state.

[0223] If the first icon is in the first state, proceed to step 7; if the first icon is not in the first state, proceed to step 8.

[0224] In this application, when the first icon is not in the first state, it is in the second state. The first state and the second state of the first icon are different, used to distinguish whether the first application corresponding to the first icon is displayed on the first desktop. When the first application's first application card is not displayed on the first desktop, the first icon is in the first state; when the first application's first application card is displayed on the first desktop, the first icon is in the second state.

[0225] This application does not limit the specific implementation of distinguishing between the first state and the second state. For example, the first icon being in the first state includes the display of a first identifier in the upper right corner of the first icon, and the first icon being in the second state includes the first icon not displaying the first identifier in the upper right corner of the first icon. The first identifier is a checkmark mark existing within a square frame displayed in the upper right corner of the first icon.

[0226] Step 7: Determine whether to execute the fourth trigger operation on the first icon.

[0227] If the fourth trigger operation is performed on the first icon, proceed to step 4; if the fourth trigger operation is not performed on the first icon, proceed to step 9.

[0228] For a detailed description of performing the fourth trigger operation on the first icon of the first application, please refer to "5. In response to the trigger operation on the first icon, change the display state of the first application card." It will not be repeated here.

[0229] Step 8: Determine whether to execute the fifth trigger operation on the first icon.

[0230] If the fifth trigger operation is performed on the first icon, proceed to step 11; if the fifth trigger operation is not performed on the first icon, proceed to step 12.

[0231] For a detailed description of performing the fifth trigger operation on the first icon of the first application, please refer to "5. In response to the trigger operation on the first icon, change the display state of the first application card." It will not be repeated here.

[0232] Step 9: Determine if the first icon meets the second trigger condition.

[0233] If the second triggering condition is met, proceed to step 4; if the second triggering condition is not met, proceed to step 10.

[0234] For a detailed description of the second triggering condition, please refer to "6. The display state of the first icon changes, thus changing the display state of the first program card." It will not be repeated here.

[0235] Step 10: In response to the second trigger operation on the first control, switch the second layout to the first layout.

[0236] For a detailed description of the second trigger operation, please refer to "2. In response to the second trigger operation on the first control, switch the second layout of the first desktop to the first layout." It will not be repeated here.

[0237] Step 11: Switch the display state of the first icon from the second state to the first state, and switch the first application card of the first application from the canceled display state to the currently displayed state.

[0238] Step 12: Determine whether the first icon meets the third trigger condition.

[0239] If the first icon of the first application meets the third trigger condition, proceed to step 11; if the first icon of the first application does not meet the third trigger condition, proceed to step 10.

[0240] For a detailed description of the fifth trigger condition, please refer to "6. The display state of the first icon changes, thus changing the display state of the first program card." It will not be repeated here.

[0241] In the above flowchart, the numbers in each step are used to uniquely identify and reference each step, and do not represent any time order, logical sequence or importance level. For example, the judgment steps of steps 3, 5 and 6 can be performed simultaneously, and the judgment steps of steps 8 and 12 can be performed simultaneously. There is no sequential relationship between the judgment steps, and this application embodiment does not impose any restrictions on this.

[0242] Figure 22 A block diagram of a human-machine interface device 2200 for a cockpit display screen provided in an exemplary embodiment of this application is shown. The in-vehicle display device 2200 includes a display module 2210 and a control module 2220.

[0243] Display module 2210 is used to display a first layout of a first desktop. The first layout includes a first area and multiple controls, among which the first control is included.

[0244] The first desktop is a desktop with program cards on the screen of the in-vehicle display device, also known as a card-style desktop. The screen of the in-vehicle display device includes one or more screen carriers such as the central control screen, passenger entertainment screen, rear entertainment screen, sliding screen, magic control screen, and central touch screen.

[0245] On in-vehicle display screens, a card-based desktop is a main screen interface or system default user interface adapted to in-vehicle driving scenarios, using application cards as the primary interaction module. The card-based desktop transforms individual in-vehicle applications or functions into independent visual application cards, presented on the screen through a segmented layout. It supports customizing the position, combination, and addition / removal of application cards, directly displaying dynamic information about the corresponding functions of the application, and providing entry points for one or more operations / functions within the application card. For example, switching tracks in a music application card or viewing the remaining trip in a navigation application card can be done without entering the full application interface, thereby improving the convenience of operation and the intuitiveness of information acquisition during driving, and meeting the safety interaction needs while driving.

[0246] The control module 2220 is also configured to switch the first layout to a second layout in response to a first trigger operation on the first control. The second layout includes a first area and a second area, wherein the first area is used to display program cards of n applications and the second area is used to display icons of m applications.

[0247] In some embodiments, when the first desktop is in the second layout, the first desktop is in an editable state. The editable state of the first desktop is a state in which program cards of n applications switch between a currently displayed state and a canceled display state, and / or a state in which icons of m applications switch between a first state and a second state. It can also be understood as a state in which a delete button appears in the upper right corner of the program cards of n applications in the first area, and at the same time, a first identifier appears in the upper right corner of the icons of n applications in the second area.

[0248] like Figure 4 As shown, the first desktop includes a first area 410 and a second area 420. The first area 410 is located above or below the second area 420. The first area 410 is used to display program cards of n applications, and the second area 420 is used to display icons of m applications. The n applications and the m applications may or may not overlap.

[0249] The types of the n and / or m applications include: navigation and positioning applications, which meet the route guidance needs while driving; audio-visual entertainment applications, which provide users with auditory and visual entertainment; vehicle control and diagnostic applications, which directly connect to vehicle hardware to monitor vehicle conditions and ensure normal vehicle operation; interconnection and interaction applications, which break down device barriers and enable the vehicle to interact with other devices and scenarios, including mobile phone-vehicle interconnection programs and / or vehicle-home interconnection programs; system tools and personalization applications, which provide download and management of various applications, optimize the vehicle user experience, and / or enable personalized customization; and communication and collaboration applications, which support voice-controlled calling functions and / or synchronize mobile phone contacts and call logs for seamless integration.

[0250] In some embodiments, the second area is used to display icons of m applications, including: displaying icons of all or some applications in the system in the second area according to user usage frequency or system preset order.

[0251] Optionally, in the second area, icons corresponding to one or more program cards on the first desktop are displayed according to the user's usage frequency or a system preset order. For example, there are three desktops, each displaying three program cards, and nine icons corresponding to these nine program cards are displayed in the second area.

[0252] Optionally, the icon order can be preset based on driving operation convenience. Alternatively, the icon order can be preset by taking into account the driver's operating posture and touch range, and / or by following the relevance of functions and the logic of usage scenarios.

[0253] The control module 2220 is used to control the linkage between the first program card and the first icon of the first application.

[0254] Wherein, the application cards of n applications include a first application card; and / or, the icons of m applications include a first icon, where n and m are both positive integers. In some embodiments, the first application card is in a first area, and the first icon is in the display area of ​​a second area, or is folded under the second area.

[0255] The linkage between the first program card and the first icon refers to the synchronized response between them in terms of function, information, and operation, achieving interoperability and information sharing to meet the safety and convenience requirements of in-vehicle scenarios. The linkage includes bidirectional synchronization of operations; when an operation is performed on the first program card or the first icon, a corresponding response will appear on the other side; and real-time synchronized display of information, where the first program card will synchronize the dynamic information of the application associated with its corresponding first icon in real time, allowing users to intuitively access content without entering the application.

[0256] In this application, the linkage between the first program card and the first icon mainly includes changing the display state of the first program card or performing an operation on the first program card, and the display state of the first icon performing a corresponding response feedback, and / or changing the display state of the first icon or performing an operation on the first icon, and the display state of the first program card performing a corresponding response feedback.

[0257] In this application, the display state of the first program card includes a displaying state and a canceled display state, and the display state of the first icon includes a first state and a second state.

[0258] The states are as follows: the first program card is displayed on the first desktop; the state of being canceled is that the first program card is not displayed on the first desktop; the first state includes the first icon displaying the first identifier; and the second state includes the first icon not displaying the first identifier.

[0259] Optionally, the first identifier is a checkmark displayed in the upper right corner of the first icon. This application does not limit the implementation of the first identifier, as long as it supports distinguishing the two states of the first icon.

[0260] In some embodiments, such as Figure 4 As shown, the operation performed on the first icon "Application 4" includes a click operation. The click operation can be implemented as follows: after the user touches the first icon "Application 4" on the screen with their finger and immediately releases it, in response to the click operation on the first icon "Application 4", the display state of the first icon "Application 4" is changed, and according to the display state of the first icon "Application 4", the corresponding operation is performed on the first program card "Program Card 4".

[0261] For example, when a user touches the first icon "App 4" on the screen and immediately releases their finger, in response to the click operation on the first icon "App 4", the check mark in the upper right corner of the first icon "App 4" disappears, and the first application card "Application Card 4" is deleted.

[0262] In some embodiments, such as Figure 5 As shown, the operations performed on the first program card "program card 4" include a click operation. The click operation can be implemented as follows: the user touches a designated position on the first program card "program card 4" on the screen and immediately releases his / her finger. For example, the user touches the delete key on the first program card "program card 4" and immediately releases his / her finger. In response to the click operation on the first program card "program card 4", the display state of the first program card "program card 4" is changed, and the corresponding operation is performed on the first icon according to the display state of the first program card.

[0263] For example, when a user touches the delete button on the first application card "Application Card 4" and immediately releases their finger, the first application card "Application Card 4" is deleted in response to the click operation on the first application card "Application Card 4", and the check mark in the upper right corner of the first icon "Application 4" disappears.

[0264] Optionally, if the in-vehicle display supports floating touch, the click operation can also be implemented as follows: the user does not touch the screen, but points to a designated location on the first program card on the screen with their finger. When a selection mark appears at the designated location on the first program card, the user slightly shakes their finger to change the display state of the first program card. Based on the display state of the first program card, the user performs the corresponding operation on the first icon. There are no restrictions on the way the user touches the screen or the way the user points to the screen.

[0265] For example, when the in-vehicle display supports floating touch, the user does not touch the screen. The user points to the delete key on the first program card with their finger. When the delete key on the first program card is selected, the user shakes their finger slightly to delete the first program card "Program Card 4". The check mark in the upper right corner of the first icon "Application 4" disappears.

[0266] In some optional designs, the control module is also used to switch the first layout to a second layout in response to a first trigger operation on the first control, including: In response to a first trigger operation on the first control, the first area is shifted upwards and the second area is displayed below the first area; or, the first area is shifted downwards and the second area is displayed above the first area.

[0267] In some optional designs, the control module is also used to, in response to a first trigger operation on the first control, scale down the program card size of n applications in the first area from a first size to a second size that does not overlap with the second area.

[0268] In some optional designs, the control module is also used to display q application components above the first area in response to a first trigger operation on the first control, where q is a positive integer.

[0269] In some embodiments, the control module 2220 is further configured to switch the second layout to the first layout in response to a second trigger operation on the first control.

[0270] In some embodiments, the control module 2220 is further configured to switch the second area to a canceled display state in response to a second trigger operation on the first control.

[0271] In some embodiments, the size of the application cards of n applications in the second layout is a second size, and the control module 2220 is further configured to restore the size of the application cards of n applications in the first area from the second size to the first size in response to a second trigger operation on the first control.

[0272] In some embodiments, the second layout also displays components of q applications, and the control module 2220 is further configured to cancel the display of components of q applications in response to a second trigger operation on the first control.

[0273] In some embodiments, the control module 2220 is further configured to display a second control on the program card of at least one of the program cards of n applications in the first region in response to a first trigger operation on the first control.

[0274] In some embodiments, the control module 2220 is further configured to change the display state of the first icon of the first application when the display state of the first application card of the first application changes, and / or, in response to a triggering operation on the second control on the first application card.

[0275] In some embodiments, the control module 2220 is further configured to change the display state of the first program card of the first application when the display state of the first icon of the first application changes, and / or, in response to a triggering operation on the first icon.

[0276] In some embodiments, the control module 2220 is further configured to, in response to a third trigger operation on the second control, switch the first application card of the first application from a displaying state to a canceled display state, and switch the display state of the first icon from a first state to a second state. The first state indicates that the first program card is in the display state, and the second state indicates that the first program card is in the cancel display state.
