Description

Technical Field

[0001] This application belongs to the technical field of display control, and specifically relates to a method, system, remote control, and device for multi-display remote control of a screen. Background Art

[0002] Traditional in-vehicle screen interaction methods mainly rely on direct touch and click operations, which were originally designed for interaction scenarios with a single display content. In the application environment of the split-screen dual-display technology, since two sets of images are simultaneously displayed on the screen, it is difficult for users to accurately select the target image by touch, resulting in an increase in the error operation rate and a decrease in the interaction efficiency. In addition, due to the lack of intuitive operation feedback, users may be confused because they cannot clearly distinguish the current operation object, affecting the user experience. Especially in the driving scenario, when the driver or passenger needs to quickly switch or independently control different images, the limitations of traditional touch operations are more prominent, which may increase the operation burden and even distract attention, affecting driving safety.

[0003] Therefore, how to achieve an efficient, intuitive, and safe interaction method in the split-screen dual-display technology has become a key technical problem to be solved urgently. The existing technologies have not provided a mature solution, and there is an urgent need for an innovative interaction mechanism to adapt to the user operation requirements in the dual-display scenario and improve the usability of the system and the user experience. Summary of the Invention

[0004] To solve the above technical problems, this application proposes a method, system, remote control, and device for realizing independent remote control of multiple displays on one screen.

[0005] Specifically, this application proposes a method for multi-display remote control of a screen, including pre-integrating and deploying multiple multi-antenna UWB anchors on the screen. The method for multi-display remote control of the screen includes: Communicating with the corresponding UWB anchor through a UWB remote control to obtain phase difference data.

[0006] Obtaining the target pointing position of the UWB remote control relative to the screen based on the phase difference data.

[0007] And controlling the corresponding process on the screen based on the target pointing position.

[0008] In the above technical content, by integrating multiple UWB anchors with multiple antennas on the screen and combining with a UWB remote control for high-precision spatial positioning and pointing positions, precise remote control operations in the multi-display environment of the in-vehicle display screen are achieved. Through the phase difference data of multiple UWB anchors, the spatial position of the UWB remote control and the precise position pointing to the screen can be effectively calculated, thereby distinguishing which part of the display content the user is operating on. It effectively solves the inconvenience of users operating the screen in the multi-display mode. By positioning the spatial position and target pointing position of the UWB remote control, the accuracy of controlling the display screen content is improved, and misoperations are avoided. Multiple UWB remote controls can work simultaneously, and different display contents in the display screen are independently displayed and controlled respectively, supporting multi-user parallel operations, effectively improving the user experience. It avoids the safety hazards existing when directly touching the screen with hands for control.

[0009] As an implementation manner, each of the UWB remote controls is at least integrated with a UWB component and a Bluetooth component. The UWB remote control is connected to the screen through the Bluetooth component, and pulse communication is performed with the corresponding UWB anchor through the UWB component.

[0010] The combination of the Bluetooth component and the UWB component can achieve more efficient and stable interactive control. The Bluetooth component has the characteristics of low power consumption and stable pairing, which can make the power consumption of the remote control low in the standby state and can maintain the connection for a long time. Through the UWB component, the spatial position and pointing of the UWB remote control can be accurately calculated, ensuring the accuracy of screen control. By integrating the UWB component and the Bluetooth component in the UWB remote control and sharing the control signal transmission by the Bluetooth component, the UWB component focuses on positioning calculations, which can effectively improve the communication efficiency.

[0011] Furthermore, obtaining the target pointing position of the UWB remote control relative to the screen includes: Sending a forward pulse signal from the UWB component of each UWB remote control to the corresponding UWB anchor.

[0012] Obtaining the first phase difference data of each antenna of the UWB anchor based on the forward pulse signal.

[0013] Obtaining the spatial position of the UWB remote control based on the first phase difference data.

[0014] By utilizing the phase differences of the pulse signals received by multiple antennas of the UWB anchors to obtain the first phase difference data, sub-centimeter-level spatial positioning accuracy can be achieved. The UWB pulse signal has an extremely narrow time resolution, which can effectively distinguish the direct signal from the reflected signal, reduce the influence of the multipath effect, and ensure the positioning stability. By obtaining the first phase difference data through the phase differences of multiple antennas, even if some antennas are blocked, the spatial position of the UWB remote control can still be obtained through the phase difference data of the remaining antennas, improving the fault tolerance of the system.

[0015] Further, the obtaining of the target pointing position of the UWB remote control relative to the screen further includes: Sending reverse pulse signals from each UWB anchor to the corresponding UWB remote control; obtaining the second phase difference data of each antenna of the UWB remote control based on the reverse pulse signals; obtaining the positions of each UWB anchor based on the second phase difference data.

[0016] By multiple UWB anchors transmitting reverse pulse signals and the UWB components of the UWB remote control receiving the reverse pulse signals, the accuracy and stability of the obtained target pointing position of the UWB remote control relative to the screen can be ensured. Utilizing the reverse pulse signals to obtain the second phase difference data of each antenna of the UWB remote control, and then obtaining the positions of each UWB anchor based on the second phase difference data, ensures the accuracy and reliability of the obtained UWB anchors.

[0017] Further, the obtaining of the target pointing position of the UWB remote control relative to the screen further includes: Based on the positions of the UWB anchors and the spatial position of the UWB remote control, obtaining the spatial pointing positions of each UWB remote control relative to its corresponding UWB anchor.

[0018] Based on the positions of the UWB anchors and the spatial pointing positions, obtaining the target pointing positions of each UWB remote control relative to the screen.

[0019] According to the positions of the UWB anchors on the screen and the spatial position of the UWB remote control, obtaining the spatial pointing positions of the UWB remote control relative to the UWB anchors improves the confidence level of the final pointing position of the UWB remote control to the screen. Establishing independent UWB anchors for each UWB remote control ensures the isolation of operation data of multiple users and ensures the independent control of each UWB remote control over the application processes in the screen.

[0020] Further, controlling the corresponding process on the screen based on the target pointing position includes: Sending the target pointing position to the screen through the Bluetooth components in each UWB remote control; determining the process on the screen corresponding to the target pointing position based on the address of the Bluetooth component to control the determined process.

[0021] By establishing a unique binding relationship between the addresses of each Bluetooth component and the corresponding screen partitions, it is ensured that the UWB remote control can accurately control the processes of the corresponding screen partitions, ensuring that multiple users can control the screen simultaneously without interference from each other. Through the Bluetooth components of the UWB remote control and the Bluetooth components of the screen for communication, UWB has high-frequency positioning, and Bluetooth transmits lightweight control instructions, effectively reducing the communication load compared with the pure UWB solution.

[0022] Based on the same inventive concept, the present application also proposes a system for a screen multi-display remote control method, the system comprising: A data acquisition module, configured to communicate with a corresponding UWB anchor through a UWB remote control to acquire phase difference data.

[0023] A position acquisition module, configured to acquire a target pointing position of the UWB remote control relative to the screen based on the phase difference data.

[0024] And a process control module, configured to control a corresponding process on the screen based on the target pointing position.

[0025] Further, the position acquisition module further includes a remote control position acquisition module, an anchor position acquisition module, and a target pointing position acquisition module.

[0026] Wherein, the remote control position acquisition module is configured to send a forward pulse signal from each UWB remote control to a corresponding UWB anchor, acquire first phase difference data of each antenna of the UWB anchor based on the pulse signal, and acquire the spatial position of each UWB remote control based on the first phase difference data.

[0027] The anchor position acquisition module is configured to send a reverse pulse signal from each UWB anchor to a corresponding UWB remote control, acquire second phase difference data of each antenna of the UWB remote control based on the reverse pulse signal, and acquire the positions of each UWB anchor based on the second phase difference data.

[0028] The target pointing position acquisition module is configured to acquire a spatial pointing position of each UWB remote control relative to its corresponding UWB anchor based on the UWB anchor position and the spatial position of the UWB remote control, and acquire a target pointing position of each UWB remote control relative to the screen based on the UWB anchor position and the spatial pointing position.

[0029] Based on the same inventive concept, the present application also proposes a remote control, at least including a UWB component and a Bluetooth component, connecting the remote control to the screen through the Bluetooth component, and performing pulse communication with a corresponding UWB anchor deployed on the screen through the UWB component to implement the screen multi-display remote control method.

[0030] Based on the same inventive concept, the present application also provides a computer device, including a processor and a memory. The memory stores computer-executable instructions that can be read by the processor and execute the screen multi-display remote control method.

[0031] Compared with the prior art, the present application has at least the following beneficial effects: The present application effectively solves the inconvenience of users operating the screen in a one-screen multi-display mode. Through the positioning of the spatial position and the target pointing position of the UWB remote control, the accuracy of controlling the content of the display screen is improved, and misoperations are avoided. By integrating multiple multi-antenna UWB anchors on the screen and combining with the UWB remote control for high-precision spatial positioning and pointing position, precise remote control operations in the one-screen multi-display environment of the vehicle-mounted display screen are realized. Through the phase difference data of multiple UWB anchors, the spatial position of the UWB remote control and the precise position pointing to the screen can be effectively calculated, so as to distinguish which part of the display content the user is operating on. Multiple UWB remote controls can work simultaneously, and different display contents in the display screen are independently displayed and controlled respectively, supporting multi-user parallel operations, effectively improving the user experience. It avoids the safety hazards caused by the driver directly touching the screen with his hand for control. Description of the Drawings

[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or server that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0037] Embodiment 1: Please refer to Figure 1 , and this screen multi-display remote control method mainly includes steps S1 to S3.

[0038] Among them, step S1 includes: communicating with the corresponding UWB anchor through the UWB remote control to obtain phase difference data. Multiple antennas are deployed in the UWB remote control and the UWB anchor. The UWB remote control at least includes a UWB component and a Bluetooth component. A forward pulse signal is sent through the UWB component, and the multiple antennas of the corresponding UWB anchor receive the forward pulse signal. Due to the phase differences of the multiple antennas, phase difference data of each antenna is obtained. For example, as Figure 3 described, three antennas are deployed in the UWB anchor, and the obtained multiple phase difference data are respectively PDOA1, PDOA2, and PDOA3.

[0039] Step S2 includes: obtaining the target pointing position of the UWB remote control relative to the screen based on the phase difference data. Among them, multiple arrival angles of the pulse signal reaching the position of the UWB anchor deployed on the screen can be calculated through the multiple phase difference data, and the spatial position of the UWB remote control is determined based on the multiple arrival angles. The target pointing position of the UWB remote control relative to the screen is obtained based on the spatial position.

[0040] And step S3 includes: controlling the corresponding process on the screen based on the target pointing position. The processes on the screen can be one or more. For example, when two application processes on the screen need to be controlled simultaneously, two UWB anchors need to be deployed on the screen, and two UWB remote controls communicate with the two UWB anchors to control these two application processes respectively, so as to achieve independent control of dual display on one screen. Based on the target pointing position, the process on the screen can be accurately controlled.

[0041] In the specific implementation process, by pre-integrating and deploying multiple multi-antenna UWB anchors on the screen, please refer toFigure 2 , two UWB anchors are integrally deployed above the screen. The UWB remote control is connected to the screen through the Bluetooth component in the UWB remote control, and a forward pulse signal is transmitted through the antenna on the UWB remote control. The corresponding UWB anchor on the screen receives the forward pulse signal, so as to obtain a plurality of phase difference data according to the phase difference of the forward pulse signals received by multiple antennas in the UWB anchor. Based on the phase difference data, a plurality of arrival angles of the forward pulse signal reaching the position of the corresponding UWB anchor on the screen are obtained, and the spatial position of the UWB remote control is determined based on the arrival angles. Based on the spatial position, the target pointing position of the UWB remote control relative to the screen is obtained. Refer to Figure 2 , two application processes are deployed in the host screen. Process 1 is controlled through the target pointing position of UWB remote control 1 relative to the screen, and process 2 is controlled through the target pointing position of UWB remote control 2 relative to the screen, so as to realize multi-display remote control on one screen.

[0042] In some embodiments, each UWB remote control is at least integrated with a UWB component and a Bluetooth component. The UWB remote control is connected to the screen through the Bluetooth component, and pulse communication is performed with the corresponding UWB anchor through the UWB component.

[0043] Please refer to Figure 2 , a Bluetooth component is integrated in each UWB remote control, and is connected to the Bluetooth component in the host screen through the Bluetooth component to transmit control instructions for the processes in the screen. A forward pulse signal is transmitted from the multiple antennas in the UWB remote control to the UWB anchor deployed on the screen, and pulse communication is performed through the multiple antennas deployed in the UWB anchor to determine the spatial position of the UWB remote control and the target pointing position relative to the screen, so as to control the corresponding application process on the screen according to the control instructions transmitted by the Bluetooth component.

[0044] Optionally, obtaining the target pointing position of the UWB remote control relative to the screen includes: Sending a forward pulse signal from the UWB component of each UWB remote control to the corresponding UWB anchor; obtaining first phase difference data of each antenna of the UWB anchor based on the forward pulse signal; obtaining the spatial position of the UWB remote control based on the first phase difference data.

[0045] Among them, a plurality of first phase difference data are obtained based on the multiple antennas deployed in the UWB anchor, for example Figure 3As described above, three antennas can be set in the UWB anchor. The forward pulse signal is received by the UWB anchor. Due to the phase differences of the three antennas, three different phase difference data PDOA1, PDOA2, and PDOA3 can be obtained. Based on each first phase difference data, multiple arrival angles of the forward pulse signal arriving at the UWB anchor can be calculated, and the spatial position of the UWB remote control can be obtained based on the arrival angles.

[0046] Optionally, obtaining the target pointing position of the UWB remote control relative to the screen further includes: Sending reverse pulse signals from each UWB anchor to the corresponding UWB remote control; obtaining second phase difference data of each antenna of the UWB remote control based on the reverse pulse signals; obtaining the positions of each UWB anchor based on the second phase difference data.

[0047] By sending the reverse pulse signal emitted by the UWB anchor to the UWB remote control to obtain the second phase difference data of each antenna of the UWB remote control, thereby obtaining the position of the UWB anchor, which ensures the accuracy of the obtained UWB anchor position. For example, sending a reverse pulse signal from UWB anchor 2 to UWB remote control 2, based on the reverse pulse signal, the second phase difference data PDOA1, PDOA2, and PDOA3 of each antenna of the UWB remote control, and obtaining the position of UWB anchor 2 on the screen based on the second phase difference data.

[0048] Optionally, obtaining the target pointing position of the UWB remote control relative to the screen further includes: Based on the position of the UWB anchor and the spatial position of the UWB remote control, obtaining the spatial pointing position of each UWB remote control relative to its corresponding UWB anchor.

[0049] Based on the position of the UWB anchor and the spatial pointing position, obtaining the target pointing position of each UWB remote control relative to the screen.

[0050] Among them, since the position of the UWB anchor in the screen is fixed and unchanged, the spatial pointing position of the UWB remote control relative to its corresponding UWB anchor can be obtained according to the position of the UWB anchor and the spatial position of the UWB remote control. The spatial pointing position of the UWB remote control relative to the UWB anchor can be converted into the target pointing position relative to the screen according to the position of the UWB anchor in the screen.

[0051] Optionally, controlling the corresponding process on the screen based on the target pointing position includes: Sending the target pointing position to the screen through the Bluetooth component in each UWB remote control; determining the process on the screen corresponding to the target pointing position based on the address of the Bluetooth component to control the determined process.

[0052] Connect with the Bluetooth components in each UWB remote control through the Bluetooth components pre-integrated and deployed in the screen. Send the target pointing position to the Bluetooth component of the screen through the Bluetooth component in the UWB remote control, and then transmit the control instructions issued by the UWB remote control to the screen based on the Bluetooth component to control the application process in the screen. The Bluetooth component in each UWB remote control has a unique address, and the address corresponds to an application process in a screen partition in the screen, so as to control the processes in multiple partitions of the screen respectively based on the Bluetooth addresses of multiple UWB remote controls, realizing multi-person sharing of independent screen interactions in one screen.

[0053] In the specific implementation process, the technical content described in this case can be applied not only to the multi-display control of in-vehicle screens, but also to other screens, such as TV screens, computers, etc. By pre-setting multiple UWB anchors in the screen, and setting multiple antennas in each UWB anchor for receiving the forward pulse signals emitted by the UWB remote control. Each UWB remote control is integrated with a UWB component and a Bluetooth component. Among them, the Bluetooth component of the UWB remote control is connected to the Bluetooth component in the screen, and each Bluetooth component has a unique address, and the address corresponds to the process in a screen partition in the screen. Each UWB remote control is responsible for remotely controlling the application process in the screen partition corresponding to the address of its Bluetooth component. Multiple antennas are also deployed in the UWB component of the UWB remote control for receiving the reverse pulse signals emitted by the UWB anchor. Thus, the specific position of the corresponding UWB anchor can be obtained in real time based on the reverse pulse signal.

[0054] For example, deploy two three-antenna UWB anchors on the in-vehicle host screen. The host screen is respectively connected to two UWB remote controls through Bluetooth components. UWB remote control 1 communicates with UWB anchor 1. UWB remote control 1 transmits a forward pulse signal to UWB anchor 1, and three different first phase difference data PDOA1, PDOA2, and PDOA3 are obtained based on the phase differences of the three antennas in UWB anchor 1. The spatial position of UWB remote control 1 is obtained through these three phase difference data. Then, a reverse pulse signal is transmitted from UWB anchor 1 to UWB remote control 1, and second phase difference data is obtained based on the three antennas of the UWB component in UWB remote control 1. Based on this second phase difference data, the position of UWB anchor 1 can be obtained. Since the position of UWB anchor 1 on the screen remains unchanged, the spatial pointing position of UWB remote control 1 relative to UWB anchor 1 can be obtained according to the spatial position of the UWB remote control. According to the position of the UWB anchor on the screen, the spatial pointing position of UBW remote control 1 relative to UWB anchor 1 can be converted into the target pointing position of UWB remote control 1 relative to the screen. Similarly, the spatial pointing position of UWB remote control 2 relative to UWB anchor 2 can be obtained and converted into the target pointing position of UWB remote control 2 relative to the screen. The target pointing positions are respectively sent to the Bluetooth component of the vehicle-mounted screen through the Bluetooth components in UWB remote control 1 and UWB remote control 2, and based on the screen partitions corresponding to the addresses of the Bluetooth components in each UWB remote control, the application processes in this screen partition are controlled. Thus, UWB remote control 1 and UWB remote control 2 can issue control instructions to independently control the application processes in different partitions of the same screen simultaneously.

[0055] Embodiment 2: Please refer to Figure 4 , this application also proposes a system adopting the screen multi-display remote control method described in Embodiment 1. The system includes: a data acquisition module, a position acquisition module, and a process control module.

[0056] The system of the screen multi-display remote control method is mainly applied to the control of the vehicle-mounted display screen. By performing pulse communication between multiple multi-antenna UWB anchors pre-integrated and deployed on the screen and the UWB remote control, the target pointing position of the UWB remote control relative to the screen is accurately obtained. The Bluetooth component in the UWB remote control is connected to the Bluetooth component of the vehicle-mounted screen to transmit control instructions for application processes, so as to perform multi-display control on the vehicle-mounted screen.

[0057] Among them, the data acquisition module is used to communicate with the corresponding UWB anchor through the UWB remote control to obtain phase difference data. A forward pulse signal is sent from the UWB remote control to the UWB anchor, and based on the phase differences of multiple antennas integrated and deployed in the UWB anchor, multiple first phase difference data can be obtained. A reverse pulse signal is transmitted from the UWB anchor to the UWB remote control, and the second phase difference data of each antenna of the UWB remote control is obtained based on the reverse pulse signal.

[0058] The position acquisition module is used to obtain the target pointing position of the UWB remote control relative to the screen based on the phase difference data. Among them, the spatial position of the UWB remote control can be mainly obtained through the first phase difference data. Then, the position of the UWB anchor is obtained through the second phase difference data. Based on the fact that the position of the UWB anchor on the screen remains unchanged, the spatial pointing position of the UWB remote control relative to the UWB anchor is obtained. Then, according to the relative position of the UWB anchor on the screen, the pointing position of the UWB remote control relative to the UWB anchor is converted into the target pointing position relative to the screen.

[0059] And, the process control module is used to control the corresponding process on the screen based on the target pointing position. Among them, the target pointing position of the UWB remote control relative to the screen is sent to the Bluetooth component of the screen through the Bluetooth component in the UWB remote control to control the application process in the corresponding screen partition on the screen, so as to realize the interaction of independent screens for multi-user screen sharing.

[0060] Furthermore, the position acquisition module further includes a remote control position acquisition module, an anchor position acquisition module, and a target pointing position acquisition module; Among them, the remote control position acquisition module is used to send forward pulse signals from each UWB remote control to the corresponding UWB anchor, obtain the first phase difference data of each antenna of the UWB anchor based on the pulse signals, and obtain the spatial positions of the UWB remote controls based on the first phase difference data.

[0061] The anchor position acquisition module is used to send reverse pulse signals from each UWB anchor to the corresponding UWB remote control, obtain the second phase difference data of each antenna of the UWB remote control based on the reverse pulse signals, and obtain the positions of the UWB anchors based on the second phase difference data.

[0062] The target pointing position acquisition module is used to obtain the spatial pointing position of each UWB remote control relative to its corresponding UWB anchor based on the UWB anchor position and the spatial position of the UWB remote control, and obtain the target pointing position of each UWB remote control relative to the screen based on the UWB anchor position and the spatial pointing position.

[0063] Embodiment 3: The present application also provides a remote controller, which at least includes a UWB component and a Bluetooth component. The remote controller is connected to the screen through the Bluetooth component, and performs pulse communication with corresponding UWB anchors deployed on the screen through the UWB component, so as to implement the screen multi-display remote control method described in Embodiment 1.

[0064] In the UWB component of the remote controller, multiple antennas can be set. The UWB component emits a forward pulse signal to perform pulse communication with the corresponding UWB anchor on the screen, and the set multiple antennas receive the reverse pulse signal emitted by the UWB anchor, so as to determine the position of the UWB anchor on the screen and the target pointing position of the UWB remote controller relative to the screen. The target pointing position and control instructions of the remote controller are sent to the screen through the Bluetooth component to control the application process in the screen. The number of antennas in the UWB component can be mainly set to three, but there is no limitation. The address of the Bluetooth component in the remote controller corresponds to the process of a screen partition in the screen, so as to control the application process of the screen partition corresponding to the address of the Bluetooth component in the screen by sending control instructions through the remote controller.

[0065] Embodiment 4: The present application also provides a computer device, which includes a processor and a memory. Computer-executable instructions are stored in the memory, and the computer-executable instructions can be read and executed by the processor to implement the screen multi-display remote control method described in Embodiment 1.

[0066] In the computer device, it can be implemented in whole or in part by software, hardware, firmware, or any combination thereof. When implemented using software, it can be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer program instructions are loaded and executed on a computer, the processes or functions described in the embodiments of the present application are generated in whole or in part. The computer can be a general-purpose computer, a special-purpose computer, a computer network, or other programmable devices. The computer instructions can be stored in a computer-readable storage medium or transmitted from one computer-readable storage medium to another. For example, the computer instructions can be transmitted from one website, computer, server, or data center to another website, computer, server, or data center via wired (such as coaxial cable, optical fiber, digital subscriber line) or wireless (such as infrared, wireless, microwave, etc.) means. The computer-readable storage medium can be any available medium that the computer can access or a data storage device such as a server or data center that includes one or more integrated available media. The available medium can be a magnetic medium (such as a floppy disk, hard disk, magnetic tape), an optical medium (such as a DVD), or a semiconductor medium (such as a solid-state disk (SSD)).

[0067] In summary, the present application effectively solves the inconvenience of users' operations on the screen in the multi-display mode of one screen. By positioning the spatial position and the target pointing position of the UWB remote control, the accuracy of controlling the content on the display screen is improved, and misoperations are avoided. By integrating multiple multi-antenna UWB anchors on the screen and combining with the UWB remote control for high-precision spatial positioning and pointing position, precise remote control operations in the multi-display environment of the in-vehicle display screen are realized. Through the phase difference data of multiple UWB anchors, the spatial position of the UWB remote control and the precise position pointing to the screen can be effectively calculated, so as to distinguish which part of the display content the user is operating on. Multiple UWB remote controls can work simultaneously, and different display contents are independently displayed and controlled on the display screen, supporting multi-user parallel operations, effectively improving the user experience.
