Description

Technical Field

[0001] This application relates to the field of racing simulation technology, and in particular to a display control method, an instrument display screen, and a racing simulator. Background Technology

[0002] In recent years, with the rapid development of science and technology and computer technology, the technology of simulating reality through virtual software has gradually been integrated into people's daily lives. Correspondingly, some virtual reality auxiliary devices have emerged, such as racing simulators. A racing simulator is an e-sports racing game simulator. In order to visually enhance the user's immersion in the simulated racing, racing simulators are generally equipped with instrument displays.

[0003] However, existing instrument displays are typically only used to simulate the dashboard, simulated track, equipment parameters, and other information of various brands and types of racing cars. They cannot directly interact with the host terminal that displays the game screen. Therefore, additional hardware devices such as buttons, mice, and keyboards are required to control the host terminal. This results in higher manufacturing costs and complexity for racing simulators, as well as additional placement space. It also greatly affects the smoothness, operational safety, and user immersion of the racing simulator. Summary of the Invention

[0004] The main technical problem addressed by this application is to provide a display control method, an instrument display screen, and a racing simulator, in order to solve the problem that the display control method in the prior art requires additional hardware devices such as buttons, mice, and keyboards to control the host terminal, which results in a large manufacturing cost and complexity for the racing simulator, requires additional placement space, and also greatly affects the smoothness, operational safety, and user immersion of the racing simulator.

[0005] To address the aforementioned problems, the first aspect of this application provides a display control method applied to an instrument display screen of a racing simulator. The method includes: acquiring touch point sampling data generated by the instrument display screen in response to user touch operations; identifying the touch point sampling data to determine the touch mode of the instrument display screen; wherein the touch mode includes an instrument interaction mode and a host interaction mode; in response to the touch mode being a host interaction mode, generating a host touch command using the touch point sampling data; and sending the host touch command to the instrument display screen and a host terminal to cause the instrument display screen to display a host interaction interface and to control the host terminal.

[0006] The display control method further includes: in response to the touch mode being an instrument interaction mode, generating an instrument touch command using touch sampling data; sending the instrument touch command to the instrument display screen to display the instrument interaction interface, and / or switching the display interface of the instrument interaction interface; acquiring the instrument editing command generated by the user input operation received by the instrument interaction interface; adjusting and configuring the instrument interaction interface in response to the instrument editing command, and / or adjusting the device parameters or the device preset configuration.

[0007] The host interaction mode includes a mouse simulation mode and a virtual button mode. Responding to the touch mode as the host interaction mode, the steps of generating host touch commands using touch sampling data include: responding to the touch mode as the mouse simulation mode, generating mouse touch commands using touch sampling data; sending the host touch commands to the instrument display screen and the host terminal, so that the instrument display screen displays the host interaction interface, and performing command control on the host terminal includes: sending mouse touch commands to the instrument display screen and the host terminal, so that the instrument display screen displays the mouse simulation interface, and performing mouse command control on the host terminal.

[0008] The steps of generating host touch commands using touch sampling data in response to a host interaction mode include: generating button mode commands using touch sampling data in response to a virtual button mode; and sending the host touch commands to the instrument display screen and the host terminal to display the host interaction interface on the instrument display screen and control the host terminal using commands. These steps include: sending button mode commands to the instrument display screen to display a virtual button interface; receiving virtual button commands generated by user pressing operations on the virtual button interface; and sending the virtual button commands to the host terminal to control the host terminal using button commands.

[0009] The touch mode also includes a lighting control mode, and the display control method further includes: in response to the touch mode being a lighting control mode, generating a lighting control command using touch sampling data; sending the lighting control command to the lighting display component to adjust the lighting display of the lighting display component; and / or sending the lighting control command to the instrument display screen to make the instrument display screen display a lighting effect editing interface; obtaining the lighting effect editing command generated by the user input operation in the lighting effect editing interface; adjusting the lighting control command in response to the lighting effect editing command; and / or sending the lighting effect editing command to the host terminal to make the host terminal store the lighting effect editing command.

[0010] Before the step of identifying the touch sampling data to determine the touch mode of the instrument display, the method further includes: detecting whether the touch feature parameters of the touch sampling data are within a first threshold range; if the touch feature parameters are within the first threshold range, acquiring the simulated racing car status parameters sent by the host terminal; adjusting the first threshold range in response to the simulated racing car status parameters, and / or adjusting the priority setting of the host touch command; if the touch feature parameters are not within the first threshold range, deleting the touch sampling data.

[0011] The process includes, after identifying the contact sampling data to determine the touch mode of the instrument display, acquiring the simulated racing car status parameters sent by the host terminal; detecting whether the simulated racing car status parameters are within a second threshold range; and disabling the host interaction mode if the simulated racing car status parameters are not within the second threshold range.

[0012] The step of identifying the touch sampling data to determine the touch mode of the instrument display screen includes: acquiring the operating status parameters of the instrument display screen and the host status parameters sent by the host terminal; identifying the touch sampling data, operating status parameters, and host status parameters to determine the touch mode of the instrument display screen.

[0013] To address the aforementioned problems, a second aspect of this application provides an instrument display screen, comprising a control component and a screen component, wherein the control component is connected to the screen component and is used for communication with a host terminal; wherein the control component uses the display control method described in any of the preceding claims to control the screen component and / or the host terminal.

[0014] To address the aforementioned issues, a third aspect of this application provides a racing simulator, which includes an instrument display screen and a host terminal, wherein the instrument display screen is communicatively connected to the host terminal; and the instrument display screen is the one described above.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, the display control method of this application obtains touch point sampling data generated by the instrument display screen sensing the user's touch operation, identifies the touch point sampling data, determines the touch mode of the instrument display screen, and when the touch mode is the host interaction mode, generates host touch commands using the touch point sampling data. These host touch commands are then used to display the host interaction interface on the instrument display screen and control the host terminal. This eliminates the need for additional hardware control devices for the host terminal. By displaying information such as the simulated racing car dashboard, simulated track, and equipment parameters on the instrument display screen, interactive control of the host terminal is achieved, reducing the manufacturing cost and complexity of the racing simulator and avoiding the need for additional hardware control devices. Furthermore, by integrating the interface display and interactive control on the same instrument display screen, it also avoids distraction between different devices, thereby effectively improving the smoothness, operational safety, and user immersion of the racing simulator.

[0020] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a flowchart illustrating the first embodiment of the control method shown in this application. Figure 2 This is a schematic diagram of one embodiment of the instrument display screen of this application. Specifically, it may include the following steps: S11: Acquire touch sampling data generated by the instrument display screen sensing user touch operations.

[0022] It is understood that the display control method in this embodiment is specifically applied to, for example... Figure 2 In the display control of the instrument display screen 100 shown, the instrument display screen 100 is specifically a display screen on a racing simulator (not shown in the figure). It is generally magnetically attached or fixedly installed on any reasonable location on the racing simulator, such as the steering wheel, base, or center console, to simulate and display information such as the instrument panel, simulated track, and equipment parameters of various brands and types of racing cars. Of course, in other embodiments, this display control method can also be applied to electric control handles, smart cockpits, industrial robots, or other reasonable electronic devices, and this embodiment does not impose any limitations on this.

[0023] In some embodiments, the instrument display screen 100 may specifically include a screen assembly 101 and a control assembly (not shown); or, the control assembly may be independent of the instrument display screen 100 and used for communication connection with the screen assembly 101; wherein, the control assembly implements display control on the screen assembly 101 using any of the display control methods described herein.

[0024] In some embodiments, the screen component 101 may be any reasonable touch display panel capable of sensing touch feedback signals generated by user touch operations, such as vector pressure sensing type, resistive type, capacitive type, surface acoustic wave type, infrared type, or surface acoustic wave type. It is preferably a capacitive touch screen to adapt to multi-point and sensitive interaction scenarios, or preferably an infrared touch screen to adapt to scenarios where users use gloves for touch operations. This application does not limit this.

[0025] In some embodiments, the control component may specifically include any reasonable circuit unit with signal processing function, such as a control chip, a DSP (Digital Signal Processing) chip, an MCU (Micro Controller Unit) circuit, a CPU (Central Processing Unit), a microcontroller, a field-programmable gate array, a programmable logic device, a discrete gate or transistor logic device, or discrete hardware. This application does not limit the scope of the application.

[0026] Specifically, the screen component 101 is used to sense user touch operations to generate corresponding touch sampling data, such as touch coordinates, touch pressure, touch area, sliding trajectory and speed, multi-touch state (single finger / two fingers), touch duration, and any reasonable characteristic parameters that reflect the user touch operation, and sends the touch sampling data to the control component. This application does not limit this.

[0027] S12: Identify the contact sampling data to determine the touch mode of the instrument display screen.

[0028] The control component uses a gesture recognition algorithm to identify the contact sampling data and determine the current touch mode of the instrument display screen 100.

[0029] It is worth noting that the gesture recognition algorithm can specifically employ a rule engine (threshold / state machine) or a lightweight ML (Machine Learning) model (running on the control component or host terminal) to improve recognition robustness.

[0030] In some embodiments, the touch mode may specifically include an instrument interaction mode and a host interaction mode; the control component may specifically use one or more combinations of touch area, gesture type, duration, multi-point operation, and context state as the basis for identification to determine whether the current touch mode of the instrument display screen 100 is an instrument interaction mode or a host interaction mode. For example, when the coordinates corresponding to the touch sampling data are in the tachometer or fuel gauge area of ​​the display interface, it is determined to be the instrument interaction mode; when they are in the edge area or the preset host entry area, it is determined to be the host interaction mode. When the gesture type is recognized as a click or short swipe, it is determined to be the instrument interaction mode; when the gesture type is recognized as a long press, double click, or specific gesture (such as drawing a circle), it is determined to be the host interaction mode. When the duration of the user touch operation corresponding to the touch sampling data is less than 300ms, it is determined to be the instrument interaction mode; when the duration of the user touch operation corresponding to the touch sampling data is greater than or equal to 500ms, it is determined to be the host interaction mode. When the multi-point operation is primarily single-finger, it is determined to be the instrument interaction mode; when the multi-point operation supports two-finger zoom / swipe, it is determined to be the host interaction mode. When the context state is "In Race → Prioritize Instrument", it is determined to be the instrument interaction mode; when the context state is "Pause / Menu State → Allow Host Interaction", it is determined to be the host interaction mode. This application does not limit this.

[0031] In other embodiments, the instrument display screen 100 may also be provided with physical buttons to switch the touch mode through any one or a combination of the physical buttons and the screen components 101, or the touch mode may be switched by the host terminal strategy. This application does not limit this.

[0032] S13: In response to the touch mode being host interaction mode, generate host touch commands using touch sampling data.

[0033] After determining that the touch mode is the host interaction mode, the identified touch sampling data, such as gestures or touch sequence, is mapped to host touch commands.

[0034] S14: Send the host touch command to the instrument display screen and the host terminal so that the instrument display screen displays the host interactive interface and performs command control on the host terminal.

[0035] The control component is also used to communicate with a host terminal, which can be understood as a terminal device that runs a racing simulator program and displays a racing simulator screen.

[0036] In some embodiments, the control component can communicate with the host terminal using any reasonable communication method such as USB HID (Human Interface Device), low-latency touch pipeline, Bluetooth, or local area network. Preferably, the communication connection between the two is achieved through a low-latency touch pipeline, so that the control component can perform sampling, edge filtering, local prediction, and the host terminal can minimize the mapping to achieve a low-latency, smooth pointer movement experience. This application does not limit this.

[0037] It is worth noting that minimizing mapping union is a technique that achieves efficient integration of multiple systems or datasets by optimizing resource consumption or cost.

[0038] This control component uses the standard USB HID mouse protocol by default to communicate with the host terminal, ensuring plug-and-play functionality. It also supports sending gestures / trigger events to the sim racing's proprietary interface for deeper interaction. This control component reports host touch events, which are then converted into mouse or virtual keyboard events by a plugin in the host terminal.

[0039] Specifically, the control component sends the host touch command to the instrument display screen 100 so that the instrument display screen 100 displays the host interactive interface, such as a display interface with a specific grayscale, or a specific virtual button selection box, or any reasonable interface that facilitates the control of the host terminal.

[0040] The control component is also used to synchronously send host touch commands to the host terminal, so as to control the host terminal in real time in response to user touch operations.

[0041] The above solution, through the instrument display screen 100, not only displays information such as the simulated racing car dashboard, simulated track, and equipment parameters, but also enables interactive control of the host terminal. This eliminates the need for additional hardware control devices for the host terminal, reducing the manufacturing cost and complexity of the racing simulator and avoiding the need for additional hardware control devices. Furthermore, by integrating the interface display and interactive control onto the same instrument display screen 100, it also avoids distraction between different devices, thereby effectively improving the smoothness, operational safety, and user immersion of the racing simulator.

[0042] Furthermore, during simulated driving, the driver can focus 100% on the instrument display screen and seamlessly switch to host control when paused; system settings can be completed without an additional keyboard / gamepad; all interactions are concentrated in front of the steering wheel, conforming to the real racing experience, achieving a seamless, safe, and intuitive switch between "driving focus" and "system control".

[0043] Please continue reading. Figure 3 , Figure 3 yes Figure 1 A flowchart illustrating an embodiment of S11 is shown. In one embodiment, the display control method of this application, in addition to the above-described S11-S14, further includes some more specific steps. Specifically, S11 may further include the following steps: S111: Obtain the set of touch points generated by the instrument display screen sensing user touch operations.

[0044] Specifically, the screen component 101 uses a sampling rate of 100-200Hz, preferably 120Hz, to collect touch point and multi-point data of user touch operations, and reports the touch point set data.

[0045] In some embodiments, the screen component 101 may specifically be a capacitive multi-touch screen that supports at least 5 concurrent touch points and has a resolution and sampling rate that meet the requirements for smooth mouse interaction.

[0046] S112: The contact point set data is filtered and calibrated sequentially to obtain the contact point sampling data.

[0047] Understandably, in order to improve the accuracy and stability of recognizing user touch operations, it is also necessary to perform filtering, data calibration, and other processing on the touch point set data.

[0048] In some embodiments, the instrument display screen 100 may further include a touch controller, which is communicatively connected to a control component for performing one or more of the following data processing operations on the touch point set data: low-level sampling, preliminary filtering, jitter removal, and coordinate normalization (from physical touch area to screen resolution). For example, EMA (Exponential Moving Average) or Kalman filtering may be used to apply EMA to short-term jitter and combine a speed threshold to distinguish between intentional movement and micro-jitter; or the touch point sequence may be divided into time windows, such as 20-50 ms, and the start and end of the touch points may be identified to obtain touch point sampling data. This application does not limit this to any particular method.

[0049] Please continue reading. Figure 4 , Figure 4 yes Figure 1A flowchart illustrating an embodiment of S12 is shown. In one embodiment, the display control method of this application, in addition to the above-described S11-S14, further includes some more specific steps.

[0050] Specifically, the control component detects and acquires the operating status parameters of the instrument display screen in real time, such as one or more of any reasonable status parameters, including the display interface on the instrument display screen, the start / stop status of the background application, and the running status of the set program. This application does not limit this.

[0051] Furthermore, the control component is also used to receive host status parameters obtained by real-time monitoring of the local operating status sent by the host terminal, such as one or more of any reasonable status parameters, such as the host display interface, the start / stop status of the host application, the setting program running status, and the running simulation racing status parameters. This application does not limit this.

[0052] S122: Identify the contact sampling data, operating status parameters, and host status parameters to determine the touch mode of the instrument display screen.

[0053] Furthermore, the control component comprehensively identifies the currently acquired touch sampling data, operating status parameters, and host status parameters based on gesture recognition algorithms and preset recognition calculation programs to determine the current touch mode of the instrument display screen 100.

[0059] S24: Send the instrument touch command to the instrument display screen to make the instrument display screen show the instrument interaction interface, and / or switch the display interface of the instrument interaction interface.

[0060] The instrument touch command is sent to the instrument display screen 100 to make the instrument display screen 100 display the instrument interactive interface, such as the simulated racing instrument panel, simulated track, equipment parameters and other information; and / or, in response to the instrument touch command, the display interface of the instrument interactive interface is switched, for example, in response to the user touch operation, the instrument file (Formula One World Championship F1 / FIA World Championship GT, etc.) in the loaded display interface is switched by swiping up and down on the instrument display screen 100, or in response to swiping left and right to switch the page (main interface / tire page / engine page) in the same instrument file, so as to achieve an intuitive switching experience. This application does not limit this.

[0061] In some embodiments, the control component can specifically determine the type of triggered gesture by applying preset rules or a lightweight algorithm model in the recognition buffer, determine the instrument interaction mode, load / apply the instrument file of the racing simulator application, support reading the official instrument file format of the racing simulator application, and render / switch the instrument interaction interface in the instrument interaction mode.

[0062] In some embodiments, the instrument interface may specifically include one or more of any reasonable display interfaces such as the main interface of the simulated racing dashboard, the tire page, the engine page, the equipment parameter page, the simulated track page, and the equipment preset editing page, so as to be able to switch the display interface in response to the instrument touch command. For example, the user can swipe left or right to switch the page in the same instrument file according to the corresponding generated instrument touch command, so as to achieve an intuitive switching experience, and / or adjust and set the equipment parameters or interface layout through the equipment preset editing page. This application does not limit this.

[0097] The light control command is sent to the light display component 102 to adjust the light display of the light display component 102, such as adjusting the light display brightness, switching or selecting light effects (constant light, gradient, flashing, pulse, color switching, etc.), adjusting display parameters (frequency, duration, phase), editing or exporting the light effect script program, and any one or more of the following reasonable light display adjustments, which are not limited in this application.

[0098] S55: Sends lighting control commands to the instrument display screen to enable the display screen to show the lighting effect editing interface.

[0099] The control component is also used to synchronously send lighting control commands to the instrument display screen 100 so that the instrument display screen 100 can display the lighting effect editing interface.

[0100] In some embodiments, the lighting effect editing interface may specifically include one or more of any reasonable dialog boxes or pop-ups, such as a lighting effect scene switching dialog box, a light color dialog box, and a light display brightness dialog box; this application does not limit this.

[0101] S56: Obtain the lighting effect editing interface to receive lighting effect editing instructions generated by user input.

[0102] Understandably, the lighting effect editing interface can receive user input to generate lighting effect editing commands, such as generating a lighting effect scene switching command in response to the user clicking the lighting effect scene switching dialog box, or generating a lighting color switching command in response to the user clicking the light color dialog box, or generating a command to increase or decrease the light brightness in response to the user clicking the light display brightness dialog box, or generating a control command for a certain speed light or side light in response to the user clicking the select a certain speed light or side light dialog box, etc. This application does not limit this.

[0103] S57: Adjusts lighting control commands in response to lighting effect editing commands.

[0104] In response to a lighting effect editing command, the system enters editing mode to adjust the lighting effect script program, thereby regulating the generation logic of lighting control commands.

[0105] S58: Send the lighting effect editing command to the host terminal so that the host terminal can store the lighting effect editing command.

[0106] After editing, the lighting effect script can be previewed in real time on the instrument display screen 100, and the lighting effect script can be saved as an exportable configuration to send the lighting effect editing instructions or lighting effect script to the host terminal, so that the host terminal can store the lighting effect editing instructions or lighting effect script, or upload it to the cloud for sharing.

[0107] Furthermore, in some embodiments, the above-mentioned S53 may further include: in response to the touch mode being a light control mode, acquiring the simulated racing car status parameters sent by the host terminal; and generating a light control command using the simulated racing car status parameters and touch sampling data.

[0108] Understandably, the control component can specifically select simulated racing car state parameters as the binding trigger condition for the lighting control command. That is, when the preset state parameters are detected, the generation of the lighting control command is enabled to enhance the immersive experience of the simulated racing car. For example, DRS (Drag Reduction System) activation, ABS (Antilock Brake System) intervention, TC (Traction Control System) adjustment, a certain gear reaching the RPM (Revolutions Per Minute) threshold, RPM percentage, etc., and correspondingly select to generate lighting control commands with lighting effects (constant light, gradient, flashing, pulse, color switching, etc.) and parameters (frequency, duration, phase). This application does not limit this.

[0109] Among them, the control component can export configuration / scene switching scripts: supporting multiple sets of lighting and touch configuration combinations, and one-click switching according to the game / vehicle scene of the racing simulator, which is convenient for quick switching in the competition / multiplayer environment.

[0110] Please see Figure 9 , Figure 9 This is a flowchart illustrating the sixth embodiment of the display control method of this application. The display control method of this embodiment... Figure 1 A detailed implementation diagram of the display control method is shown, including the following steps: S61: Acquire touch sampling data generated by the instrument display screen sensing user touch operations.

[0111] Among them, S61 and Figure 1 The same applies to S11. Please refer to S11 and its related textual descriptions for details, which will not be repeated here.

[0112] S62: Detect whether the touch feature parameters of the contact sampling data are within the first threshold range.

[0113] Understandably, in order to improve the accuracy and stability of recognizing user touch operations, specific touch point shape judgment can also be performed. For example, based on the contact area / pressure difference of the user's touch operation, the palm touch and finger operation can be distinguished. When the contact area or duration is not within the preset first threshold range, it is judged as a touch and ignored.

[0114] Specifically, the control component is used to detect whether the touch feature parameters of the currently acquired touch sampling data are within a first threshold range.

[0115] In some embodiments, the touch feature parameter can be one or more of any reasonable parameters such as contact area, sliding direction, duration, and touch pressure. The first threshold range can also be one or more of any reasonable threshold range such as area threshold range, time threshold range, and pressure threshold range. This application does not limit this.

[0116] If the touch feature parameters are not within the first threshold range, then S63 is executed; if the touch feature parameters are within the first threshold range, then S64 is executed.

[0117] S63: Delete contact sampling data.

[0118] When it is determined that the touch feature parameters are not within the first threshold range, it indicates that the current user touch operation is a mis-touch or a malfunction, and the currently acquired touch sampling data is deleted.

[0119] S64: Obtain the simulated racing car status parameters sent by the host terminal.

[0120] When the touch feature parameters are determined to be within the first threshold range, it indicates that the current user touch operation is a valid operation. The host terminal can obtain the simulated racing car status parameters obtained by real-time monitoring of the simulated racing car, such as one or more of any reasonable status parameters such as the vehicle speed, steering angle, during the race, when parked, and historical parameters of the user's identity recognition. This application does not limit this.

[0121] S65: In response to the adjustment of the first threshold range of the simulated racing state parameters, adjust the priority setting of the host touch command.

[0122] Understandably, to ensure smooth gameplay, operational safety, and user immersion, the sensitivity of touch controls needs to vary depending on the sim's state. For example, during intense races, the sensitivity of the instrument display needs to be reduced to prevent accidental touches that could disrupt the immersive experience, while when the sim is stopped, the sensitivity needs to be increased for better touch control. Furthermore, the sensitivity requirements for touch operations, especially host-based touch commands such as mouse functions, also differ for different users.

[0123] Specifically, in response to the currently acquired simulated racing car status parameters, the first threshold range can be dynamically adjusted, and / or the priority of the host touch commands can be set. For example, in response to the simulated racing car speed being greater than a preset speed threshold or being in a race, the first threshold range can be increased to reduce the sensitivity of the host touch commands or completely block the host touch commands; and / or, the priority of the instrument touch commands can be adjusted to the highest, or only the instrument touch commands can be responded to, and the host touch commands can be disabled to avoid accidental touches; or, in response to changes in the historical parameters of the identified user, the first threshold range can be increased or decreased to match the usage habits of different users. This application does not limit this.

[0124] S66: Identify the contact sampling data to determine the touch mode of the instrument display screen.

[0125] S67: In response to the host interaction mode of the touch mode, host touch commands are generated using touch sampling data.

[0126] S68: Send the host touch command to the instrument display screen and the host terminal so that the instrument display screen displays the host interactive interface and performs command control on the host terminal.

[0127] Among them, S66, S67 and S68 and Figure 1 S12, S13 and S14 are the same. Please refer to the textual descriptions of S12, S13 and S14 and their related texts for details. They will not be repeated here.

[0128] Please see Figure 10 , Figure 10 This is a flowchart illustrating the seventh embodiment of the display control method of this application. The display control method of this embodiment... Figure 1 A detailed implementation diagram of the display control method is shown, including the following steps: S71: Acquire touch sampling data generated by the instrument display screen sensing user touch operations.

[0129] S72: Identify the contact sampling data to determine the touch mode of the instrument display screen.

[0130] Among them, S71 and S72 and Figure 1 S11 and S12 are the same. Please refer to the textual descriptions of S11 and S12 for details, which will not be repeated here.

[0131] S73: Obtain the simulated racing car status parameters sent by the host terminal.

[0132] Specifically, the control component receives the simulated racing car status parameters obtained from real-time monitoring of the simulated racing car sent by the host terminal, such as one or more of any reasonable status parameters of the simulated racing car, such as vehicle speed, steering angle, during the race, and when parking. This application does not limit this.

[0133] S74: Detects whether the simulated racing car's status parameters are within the second threshold range.

[0134] Understandably, in order to ensure the smoothness, operational safety, and user immersion of the sim racing in different states, the required responsiveness of user touch operations usually varies. Especially during intense races, in order to avoid accidental touches on the instrument display screen that could affect the immersion of the sim racing, it is necessary to block the host touch commands to prevent the host terminal from interrupting the sim racing screen or popping up interfering dialog boxes.

[0135] Specifically, the system detects the state parameters of the simulated racing car, such as whether the car's speed is within the second threshold range.

[0136] It is worth noting that the second threshold range can specifically be a speed threshold range or a steering angle threshold range, which can be used to determine whether the simulated race car is in a race state, or in a specific race scenario, such as when the speed of the simulated race car has exceeded the set value, or when the steering angle has exceeded the set value.

[0137] If the simulated racing car's status parameters are within the second threshold range, then S75 is executed; if the simulated racing car's status parameters are not within the second threshold range, then S76 is executed.

[0138] S75: Disable host interaction mode.

[0139] If the simulated racing car's status parameters are determined to be within the second threshold range, it indicates that the simulated racing car is in racing mode or that the simulated racing car's speed has exceeded the set value. In order to avoid affecting the immersive experience of the simulated racing car, the host interaction mode is disabled, that is, the host interaction mode is blocked and does not respond to host touch commands, but instrument touch commands are still allowed.

[0140] S76: Responds to the host interaction mode in touch mode, and generates host touch commands using touch sampling data.

[0141] If the simulated racing car's status parameters are not within the second threshold range, it indicates that the simulated racing car is in a stopped state or that the simulated racing car's speed has not exceeded the set value. After determining that the touch mode is the host interaction mode, the identified touch sampling data, such as gestures or touch sequence, will be mapped to host touch commands.

[0142] S77: Sends host touch commands to the instrument display screen and the host terminal, so that the instrument display screen displays the host interactive interface and performs command control on the host terminal.

[0143] The control component is also used to communicate with a host terminal, which can be understood as a terminal device that runs a racing simulator program and displays a racing simulator screen.

[0144] In some embodiments, the control component also includes fault tolerance, exception handling, and security mechanisms. For example, a disconnection / reconnection strategy: after disconnection from the host terminal, local editing cache is retained; after reconnection, configuration and incomplete editing operations are automatically synchronized. Concurrency conflict resolution: when conflicts exist between user touch operations and host terminal commands simultaneously, a priority strategy is adopted (e.g., user touch operations take precedence over remote commands within editing mode). Security / permissions: when sending control commands (such as exporting / writing configuration) to the host terminal, authorization confirmation from the host terminal plugin is required to prevent malicious scripts from being written to the device.

[0145] Specifically, the control component sends the host touch command to the instrument display screen 100 so that the instrument display screen 100 displays the host interactive interface, such as a display interface with a specific grayscale, or a specific virtual button selection box, or any reasonable interface that facilitates the control of the host terminal.

[0146] The control component is also used to synchronously send host touch commands to the host terminal, so as to control the host terminal in real time in response to user touch operations.

[0147] S78: In response to the touch mode as the instrument interaction mode, it generates instrument touch commands using touch sampling data.

[0148] After determining that the touch mode is the instrument interaction mode, the control component maps the identified touch sampling data, such as gestures or touch sequence, into instrument touch commands.

[0149] S79: Send the instrument touch command to the instrument display screen to make the instrument display screen show the instrument interaction interface, and / or switch the display interface of the instrument interaction interface.

[0150] Sending instrument touch commands to the instrument display screen 100 to cause the instrument display screen 100 to display the instrument interactive interface, such as a simulated racing dashboard, simulated track, equipment parameters, etc.; and / or, switching the display interface of the instrument interactive interface in response to the instrument touch commands, which is not limited in this application.

[0151] In some embodiments, the control component can specifically determine the type of triggered gesture by applying preset rules or a lightweight algorithm model in the recognition buffer, determine the instrument interaction mode, load / apply the instrument file of the racing simulator application, support reading the official instrument file format of the racing simulator application, and render / switch the instrument interaction interface in the instrument interaction mode.

[0152] In some embodiments, the instrument interface may specifically include one or more of any reasonable display interfaces such as the main interface of the simulated racing dashboard, the tire page, the engine page, the equipment parameter page, the simulated track page, and the equipment preset editing page, so as to be able to switch the display interface in response to the instrument touch command. For example, the user can swipe left or right to switch the page in the same instrument file according to the corresponding generated instrument touch command, so as to achieve an intuitive switching experience, and / or adjust and set the equipment parameters or interface layout through the equipment preset editing page. This application does not limit this.

[0153] S710: Obtain instrument editing instructions generated by user input operations through the instrument interaction interface.

[0154] Specifically, when the instrument interface corresponds to the device's preset editing page, it can also receive user input to generate instrument editing instructions and send these instructions to the control component.

[0155] S711: Adjusts and configures the instrument interface in response to instrument editing commands, and / or adjusts device parameters or device preset configurations.

[0156] The control component responds to instrument editing commands to adjust and configure the current instrument interaction interface of the instrument display screen 100, and / or adjust device parameters, such as the power parameters, 100-meter acceleration, color, etc. of the simulated racing car; and / or adjust the preset configuration of the device, such as the track scene, sound effects, start screen, etc. of the simulated racing car, etc. This application does not limit this.

[0157] Furthermore, in some embodiments, the above-mentioned S72 can be replaced by: identifying the touch sampling data based on the gesture recognition algorithm, so as to map the touch sampling data into instrument touch commands, mouse touch commands, virtual button commands or light control commands.

[0158] Understandably, this control component is based on a preset gesture recognition algorithm to recognize any reasonable gesture operation such as single click, double click, long press, swipe, zoom, and two-finger scroll. It dynamically adjusts the first threshold range and the priority of each gesture in combination with the simulated racing car state parameters, and then directly maps the recognized gesture or touch point sequence, i.e., touch point sampling data, into one of the instrument touch command, mouse touch command, virtual button command, and light control command, so as to directly use it to realize display control of the instrument display screen 100 and / or realize interactive control of the host terminal.

[0159] The mouse touch command can also be understood as a system mouse event, the instrument touch command corresponds to the instrument switching command, and the light control command corresponds to the light editing command or the light trigger event.

[0160] In some embodiments, the basic gesture set corresponding to the instrument display screen 100 for the preset gesture recognition algorithm may specifically include: a single short press as a trigger command for a left click on the host terminal; a single double click as a left double click or opening a shortcut menu; a single long press (duration > 400ms) as a right click or entering context / edit mode; a single finger swipe as switching instrument files (up and down) or turning pages (left and right) in instrument interaction mode, and as pointer movement in mouse mode; a two-finger vertical movement as scrolling the mouse wheel; a two-finger tap as a middle click / switching mode; and three-finger or more gestures can be customized as shortcut operations (such as one-click saving configuration, returning to the main interface) or any reasonable gesture rules.

[0161] The gesture priority rule is as follows: long press > two-finger operation > single-finger swipe > single-finger short press. That is, when two-finger contact is detected, it should be recognized as scrolling rather than a single-finger tap.

[0162] Race Context Suppression: When the telemetry simulation racing car status parameters indicate that the vehicle speed is greater than the set speed threshold or that the car is in a race, the mouse sensitivity is reduced or mouse clicks are completely blocked by default, allowing only important instrument switching gestures (such as swiping up and down to switch instrument files, which requires two fingers + swiping up) to avoid accidental touches.

[0163] Contact morphology judgment: Based on the contact area / pressure difference corresponding to the contact sampling data, distinguish between palm touch and finger operation; when the contact area is not within the first threshold range, it is judged as a touch and ignored.

[0164] The communication layer of this control component supports standard USB HID (mouse / multi-touch) output; it can also exchange events (e.g., enter edit mode, light binding commands, export requests) with the racing simulator application plugin or custom protocol on the host terminal via USB / network port.

[0165] The configuration / editing interface of this control component features a built-in simplified editor that allows direct editing of lighting effects on the instrument display screen 100 and export of JSON (JavaScript Object Notation, a lightweight, interpreted, or just-in-time compiled programming language key-value pair data) / binary preset files.

[0166] This application also provides a racing simulator; please refer to [link / reference needed]. Figure 11 , Figure 11 This is a schematic diagram of one embodiment of the racing simulator of this application. In this embodiment, the racing simulator 80 includes an instrument display screen 81 and a host terminal 82, and the instrument display screen 81 is communicatively connected to the host terminal 82.

[0167] It should be noted that the instrument display screen 81 described in this embodiment is the same as the instrument display screen 100 described in any of the above embodiments. Please refer to the following for details. Figures 1-9 The relevant textual content will not be elaborated upon here.

[0168] The beneficial effects of this application are as follows: Unlike the prior art, the display control method provided by this application obtains touch sampling data generated by the instrument display screen sensing user touch operations, identifies the touch sampling data, determines the touch mode of the instrument display screen, and when the touch mode is the host interaction mode, generates host touch commands using the touch sampling data. These host touch commands are then used to display the host interaction interface on the instrument display screen and control the host terminal. This eliminates the need for additional hardware control devices for the host terminal. The instrument display screen simultaneously displays information such as the racing car dashboard, simulated track, and equipment parameters while enabling interactive control of the host terminal, reducing the manufacturing cost and complexity of the racing simulator and avoiding the need for additional hardware control devices. Furthermore, by integrating the interface display and interactive control onto the same instrument display screen, it avoids distraction between different devices, effectively improving the smoothness, operational safety, and user immersion of the racing simulator.

[0169] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
