Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a position display method, system, and display device. Background Technology

[0002] With the widespread adoption of smart TVs and large-screen devices, higher demands are being placed on the naturalness, efficiency, and accuracy of interaction methods. Traditional human-computer interaction methods have significant limitations when dealing with complex operations, which has led to the development of a "trigger-oriented" interaction mode based on spatial sensing.

[0003] Ultra-wideband (UWB) technology, with its centimeter-level high-precision positioning, strong anti-interference capabilities, and high time resolution, provides a core technological foundation for achieving highly reliable spatial pointing interaction. UWB pointing remote controls (often called "air mice" or "UWB pointing remote controls") have emerged to address this need. These remote controls calculate the precise pointing coordinates in space in real time by measuring parameters such as the time-of-flight (ToF) and angle of arrival (AoA) of the wireless signal between the remote control and the television.

[0004] When the remote control's transmitting antenna is located in the near-field region of the TV's UWB receiving antenna array, the phase distribution of the signal reaching each antenna of the receiving array will be severely uneven due to the near-field effect, even at the same propagation distance, depending on the remote control's location. In other words, the phase difference between the antennas at the receiving end will change non-linearly with the remote control's spatial position. This phase distribution distortion directly causes errors in the algorithm for calculating angles based on phase differences, leading to problems such as inaccurate cursor pointing and drift.

[0005] Therefore, the technology still needs to be improved and enhanced. Summary of the Invention

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2This is a schematic diagram of the pointing direction of the remote controller 11 in the UWB pointing remote control system provided in this application embodiment. A typical UWB pointing remote control system includes a remote controller 11 and a television 12. Its core principles are divided into two categories: distance measurement and angle measurement. In distance measurement pointing determination, two UWB tags with a fixed distance between them are generally arranged on the remote controller 11 along the long axis. The television 12 calculates the distance difference by measuring the distance between the two tags. In angle measurement pointing positioning, a multi-antenna array deployed on the television 12 is used to calculate the angle of arrival of the signal from the remote controller 11 by measuring the phase difference or time difference of the UWB signal arriving at different antennas, thereby directly determining its pointing line in space.

[0033] According to antenna theory, the complete structure of an electromagnetic field is divided into the near field (Fresnel region) and the far field (Fraunhofer region). In the near field, the electromagnetic field structure is complex; the phase wavefront is not planar, its distribution is uneven, and it varies drastically with spatial position. For a UWB directional remote control system operating in the 3.1GHz-10.6GHz frequency band with a wavelength (λ) of approximately 37mm, if the antenna length (L) of the remote controller 11 is 150mm, the critical distance (d) at the start of its far field region must satisfy the formula: d ≥ 2L² / λ. Calculations show that the far field distance is at least 122mm.

[0034] However, in real-world applications, the distance between the user and TV 12 is much greater than this value, seemingly satisfying the far-field condition. The key issue lies in the fact that the receiving antenna array used for direction finding at TV 12 may have a very large aperture (D). Assuming TV 12 is 1 meter wide and has four antennas arranged side-by-side, its effective aperture (D) could reach 0.6 meters. Therefore, the starting distance for the far-field of the antenna array at TV 12, calculated using d ≥ 2L² / λ, is 19.5 meters. However, in real-world applications, it's difficult to achieve the required far-field distance. Consequently, the operating area of ​​the UWB remote control system is mostly in the near-field region relative to the far-field region. However, when the azimuth angle or downtilt angle at remote control 11 is large, the phase difference distribution fluctuates greatly, resulting in poor uniformity. When the downtilt angle relative to remote control 11 is small, the phase difference at the same azimuth angle is relatively stable and consistent; when the azimuth angle is small, the phase difference at the same downtilt angle is relatively stable.

[0035] The aforementioned tilt angle refers to the angle between the remote control 11 pointing to the horizontal plane (e.g., ...). Figure 1 In the diagram (ɑ), when the tilt angle is 0 degrees, it indicates that the remote control 11 is pointing directly forward, and the tilt angle is 0 degrees. Raising or lowering the remote control 11 will affect the tilt angle. The azimuth angle refers to the angle between the projection of the remote control 11 onto the horizontal plane and the normal to the end of the television 12 (e.g., α). Figure 2 In the case of β), when the azimuth angle is 0 degrees, it can be understood that the remote control 11 is directly facing the center of the TV 12. The azimuth angle will change when the remote control 11 is deflected to the left or right relative to the TV 12.

[0036] This application provides a location display method, system, and display device, which will be described in detail below.

[0037] The location display method provided in this application embodiment acquires the pulse signal output by the remote control device; determines the first spatial position coordinates of the remote control device based on the pulse signal; obtains the pixel coordinates of the target cursor on the target display interface based on the spatial position coordinates; and displays the target cursor on the target display interface based on the pixel coordinates; the target display interface displays a boundary for determining whether the remote control device is within the target position range in front of the display device.

[0038] Please see Figure 3 , Figure 3 This is a flowchart illustrating one embodiment of the location display method provided in this application. The location display method includes the following steps S100~S300, as detailed below: S100: Acquire the pulse signal output by the remote control device.

[0039] The remote control device is equipped with a UWB tag. The UWB RF chip inside the tag is driven by a highly stable clock, generating extremely short baseband pulses (e.g., 2 nanoseconds) at a specific repetition period (e.g., 1 million times per second). These baseband pulses are modulated onto a designated UWB frequency band (e.g., a center frequency of 6.5 GHz), amplified by a power amplifier, and then radiated omnidirectionally into space through the UWB antenna on the remote control device. This pulse signal encodes the remote control device's unique ID information; obtaining this pulse signal facilitates subsequent location tracking of the device.

[0040] S200. Determine the first spatial position coordinates of the remote control device based on the pulse signal.

[0041] By measuring the time or time difference of the pulse signal propagating from the remote control device to multiple fixed reference receivers at known locations, the distance from the remote control device to each node is calculated, and the first spatial position coordinates of the remote control device in the preset spatial coordinate system are calculated using known geometric principles.

[0042] Specifically, the steps for determining the first spatial position coordinates of the remote control device based on the pulse signal include: determining the second spatial position coordinates based on the pulse signal, and determining the first spatial position coordinates based on the second spatial position coordinates and attitude data information. The remote control device is equipped with an attitude sensor, which detects the device's acceleration and angular velocity, using these as attitude data information. The second spatial position can be understood as the initial three-dimensional spatial coordinates of the remote control device calculated based on the pulse signal using a time difference of arrival or angle of arrival algorithm. These three-dimensional spatial coordinates are then fused with the attitude data information, and the attitude is corrected and the trajectory smoothed using algorithms to obtain the first spatial position coordinates. The first spatial position coordinates represent a more optimal positioning point compared to the second spatial position coordinates.

[0043] S300: Obtain the pixel coordinates of the target cursor on the target display interface based on the first spatial position coordinates, and display the target cursor on the target display interface based on the pixel coordinates; the target display interface displays a boundary for determining whether the remote control device is within the target position range in front of the target display device.

[0044] In this embodiment, the target display device is the display device controlled by the remote control device, and the target position range refers to the area in front of the display device where the phase difference of the remote control device is relatively stable. A target display interface is established on the display device to display the position of the remote control device in front of the display device. Simultaneously, based on the known target position range, a boundary is pre-set and displayed on the target display interface. After obtaining the pixel coordinates of the target cursor based on the first spatial position coordinates, the target cursor is displayed on the target display interface. Therefore, based on the positional relationship between the target cursor and the boundary, it is possible to intuitively understand whether the remote control device is within the target position range, thus visualizing the relationship between the remote control device and the target position range. This allows the user to adjust the remote control device within the target position range, thereby mitigating the problem of inaccurate cursor pointing and drift caused by the near-field effect.

[0045] It should be noted that the boundary of the target display interface can be either a boundary surface or a boundary line. If the target display interface displays the target cursor in a three-dimensional manner, then the boundary corresponds to a boundary surface; if the target display interface displays the target cursor in a two-dimensional manner, then the boundary corresponds to a boundary line.

[0046] Please see Figure 4 , Figure 4 This is a flowchart illustrating another embodiment of the position display method provided in this application. In some embodiments, after displaying the target cursor on the target display interface according to pixel coordinates, steps S400 and S500 are included, which are detailed below: S400: Determine whether the target cursor is located within the target area defined by the boundary.

[0047] The target display interface can intuitively show the position of the remote control device in front of the display device, facilitating visual observation by the user. In some embodiments, the display device can determine whether the target cursor is within the target area defined by the boundary by comparing the position of the target cursor with the position of the boundary. This target area is used to characterize the target location range. If the target cursor is within the target area, it indicates that the remote control device is within the target location range; conversely, if the target cursor is outside the target area, it indicates that the remote control device is outside the target location range.

[0048] S500: When the target cursor is outside the target area, the first alarm message is output.

[0049] Specifically, if the target cursor is located outside the target area, it indicates that the remote control device is outside the target location range. The phase difference within the target location range is relatively stable and highly consistent, while the phase difference outside the target location range is relatively unstable. Therefore, to mitigate the impact of the near-field effect on the remote control device, which can lead to unstable phase differences outside the target location range and cause inaccurate cursor pointing or drifting, a first alarm message will be directly output to inform the user that the current position of the remote control device is outside the target location range, allowing for timely adjustment of the remote control device's position.

[0050] The first alarm information can be a voice prompt output from the display device, a display prompt indicating that the target cursor is blinking, or a display prompt indicating that a separate indicator light is illuminated, etc. The specific manner of the first alarm information is not limited in this embodiment.

[0051] In some embodiments, after step S400, the method further includes: when the target cursor is located within the target area, determining the distance between the target cursor and the boundary; when the distance is less than a preset distance, outputting a second alarm message.

[0052] Once the target cursor is confirmed to be within the target area, it indicates that the remote control device is within the target location range. The system then continues to monitor the distance between the target cursor and the boundary, determining whether to issue a warning based on this distance. If the distance between the target cursor and the boundary is less than or equal to a preset distance, it indicates that the remote control device is approaching the boundary of the target location range. To prevent the remote control device from crossing the boundary, a second alarm message can be output to provide a warning. If the distance between the target cursor and the boundary is greater than the preset distance, it indicates that the remote control device is located near the center of the target location range. In this case, no alarm message needs to be output, and the monitoring of the distance between the target cursor and the boundary continues.

[0053] The second alarm information is presented in the same way as the first alarm information. For example, the second alarm information could be a voice alarm output by a display device, a display prompt indicating a blinking target cursor, or a display prompt indicating the illumination of a separate indicator light. The difference between the second and first alarm information lies in the alarm level. For example, for voice alarm information, different alarm levels can be indicated by different voice content; for display prompts indicating a blinking target cursor, different alarm levels can be indicated by different blinking frequencies or colors; and for display prompts indicating illuminated indicator lights, different alarm levels can be indicated by different illuminated colors or numbers. This application does not specifically limit the method of indicating alarm levels.

[0054] In one embodiment, after step S400, the method further includes: when the target cursor is outside the target area, outputting a first boundary trigger command to the remote control device. When the target cursor is outside the target area, the display device can output a first alarm message. Simultaneously, a first boundary trigger command can be sent to the remote control device, causing the remote control device to output a corresponding third alarm message based on the first boundary trigger command. Similarly, the third alarm message can be a voice message, a display prompt indicating that an indicator light is on, or a vibration message, etc. Specifically, it can be selected according to actual needs, and this application does not limit it.

[0055] As one embodiment, after determining the distance between the target cursor and the boundary, the method further includes: when the distance is less than a preset distance, outputting a second boundary trigger command to the remote control device. When the distance between the target cursor and the boundary is less than the preset distance, while outputting the second alarm information on the display device side, a second boundary trigger command can also be sent to the remote control device side, causing the remote control device to output corresponding fourth alarm information according to the second boundary trigger command. Similarly, the fourth alarm information can be voice information, display prompts with indicator lights, vibration information, etc. Specifically, it can be selected according to actual needs, and this application does not limit it. The third alarm information and the fourth alarm information differ in alarm level. For example, for voice alarm information, different alarm levels can be indicated by different alarm voice content; for display prompts with indicator lights, different alarm levels can be indicated by different colors or numbers of indicator lights; for vibration information, different alarm levels can be indicated by different vibration amplitudes, etc. This application embodiment does not specifically limit the indication method of alarm level.

[0056] The target location range can be set by referring to one or more of the following parameters: the range of horizontal angles, the range of tilt angles, and the range of remote control distances from the display device. Setting the target location range by referring to all three parameters simultaneously improves the accuracy of alarm prompts. For example, the target location range can be defined as a conical space with a horizontal angle of 60 degrees to the left and right of the display device, a tilt angle of 20 degrees up and down, and a remote control distance of 1 to 4 meters. In this case, the target location range is a conical space with a tilt angle <20°, an azimuth angle <50°, and a remote control distance of 1 to 4 meters.

[0057] Please see Figure 5 , Figure 5 This application provides a phase difference distribution map within 180 degrees in front of the display device at a distance of 1.5 meters. According to this distribution map, the phase difference is large in the areas near the left and right sides of the display device (i.e., areas with large azimuth angles), and small in the area directly in front of the display device (i.e., areas with small azimuth angles). When the downtilt angle is greater than 20°, the phase difference distribution fluctuates more and the uniformity deteriorates, while in areas with a downtilt angle less than 20°, the phase difference at the same azimuth angle is relatively stable and consistent. Therefore, setting the target position range as a conical space with a downtilt angle <20°, an azimuth angle <50°, and a remote control distance of 1-4 meters, and placing the remote control device within this target position range, can alleviate the problems of inaccurate cursor pointing and drift caused by the near-field effect.

[0058] This application embodiment also provides a location display method, which acquires the pulse signal output by the remote control device; determines the first spatial position coordinates of the remote control device based on the pulse signal; obtains the pixel coordinates of the target cursor on the target display interface based on the first spatial position coordinates; and outputs alarm information when the target cursor meets the preset alarm conditions.

[0059] Unlike the method of displaying the boundary position on the target display interface, this embodiment only needs to obtain pixel coordinates to display the target cursor, without displaying the boundary on the target display interface. It only needs to compare the target cursor with the target area defined by the preset boundary. If the target coordinates are outside the target area, it indicates that the pixel coordinates meet the preset alarm conditions, and therefore an alarm message can be directly output. Similarly, if the target cursor is within the target area, but the distance between the target cursor and the boundary is less than or equal to a preset distance, it also indicates that the target coordinates meet the preset alarm conditions, and therefore an alarm message can also be directly output to prompt the user to adjust the position of the remote control device. The presentation type of the alarm message and the alarm levels for different situations can be the same as the position display method described above.

[0060] In another embodiment, after the alarm information is output, the boundary for determining whether the remote control device is within the target position range in front of the target display device can be displayed on the target display interface, so that the user can adjust the position of the remote control device by referring to the boundary, thereby improving the accuracy of the adjustment.

[0061] Please see Figure 6 , Figure 6 This is a structural block diagram of the display device provided in the embodiments of this application. The embodiments of this application also provide a display device including a display module 110, a first positioning module 120, and a first control module 130. Both the first positioning module 120 and the display module 110 are connected to the first control module 130. The first positioning module 120 is used to acquire pulse signals output by the remote control device and determine the first spatial position coordinates of the remote control device based on the pulse signals. The first control module 130 is used to obtain the pixel coordinates of the target cursor on the target display interface based on the spatial position coordinates and control the display module 110 to display the target cursor on the target display interface based on the pixel coordinates. The target display interface displays a boundary for determining whether the remote control device is within the target position range in front of the display device.

[0062] In this embodiment, the display device utilizes display module 110 to display the target cursor, the target display interface, and the boundary. After obtaining the pixel coordinates of the target cursor based on the first spatial position coordinates, the target cursor is then displayed on the target display interface. Based on the positional relationship between the target cursor and the boundary, it is possible to intuitively understand whether the remote control device is within the target position range, thus visualizing the remote control device and the target position range. This allows the user to adjust the remote control device within the target position range, thereby mitigating the problem of inaccurate cursor pointing and drift caused by the near-field effect.

[0063] Please see Figure 7 , Figure 7 This is a structural block diagram of the first positioning module 120 in the display device provided in this application embodiment. In some embodiments, the first positioning module 120 includes a communication unit 122 and a positioning unit 121. The positioning unit 121 is connected to the communication unit 122 and the control module respectively. The communication unit 122 is used to acquire the attitude data information of the remote control device. The positioning unit 121 is used to determine the second spatial position coordinates of the remote control device according to the pulse signal, and to determine the first spatial position coordinates according to the second spatial position coordinates and the attitude data information.

[0064] The remote control device is equipped with an attitude sensor, which detects the device's acceleration and angular velocity, using these as attitude data. The second spatial position can be understood as the initial three-dimensional spatial coordinates of the remote control device calculated based on pulse signals using time difference of arrival or angle of arrival algorithms. Then, the positioning unit 121 fuses these three-dimensional spatial coordinates with the attitude data, and corrects the attitude and smooths the trajectory through algorithms to obtain the first spatial position coordinates. The first spatial position coordinates are a better positioning point than the second spatial position coordinates.

[0065] As one embodiment, the first positioning module 120 can be a UWB dongle module. The UWB dongle module is installed in the display device and can interact with the display device through a connection interface (such as a USB interface). The UWB dongle module includes a communication unit 122 and a positioning unit 121. The communication unit 122 can be implemented through a first Bluetooth module. The positioning unit 121 includes a UWB receiving chip and an antenna array and a main control processor 123. The UWB receiving chip and the antenna array acquire pulse signals, and the first Bluetooth module acquires attitude data information. Finally, the main control processor 123 performs high-attitude data fusion with the attitude data processor and the second spatial position coordinates obtained from the pulse signals, thereby outputting smoother and more jitter-resistant first spatial position coordinates. Then, the first spatial position coordinates are compared with a preset target area to determine whether the remote control device is within the target position range, so as to facilitate the subsequent control of the display module 110 to display the target display interface, boundary, and target cursor, as well as the output of alarm information by other modules in the display device (such as audio modules or indicator lights).

[0066] When the main control processor 123 determines that alarm information needs to be output, it can send a corresponding trigger command to the remote control device through the first Bluetooth module.

[0067] As one embodiment, the first control module 130 can be the main controller in the display device. The main controller realizes the display of the target display interface, the target cursor and the boundary based on the first spatial position coordinates and the target area defined by the boundary output by the main control processor 123, and controls the voice module or indicator light to output alarm information accordingly.

[0068] Please see Figure 8 , Figure 8 This is a first structural block diagram of the remote control device 200 in the location display system provided in this application embodiment. This application embodiment also provides a location display system, which includes the remote control device 200 and the aforementioned display device 100. The display device 100 is used to execute the aforementioned location display method. Since the location display method has been described in detail above, it will not be repeated here.

[0069] Specifically, the remote control device 200 includes a second positioning module 210, which sends pulse signals to the display device 100. In this embodiment, the second positioning module 210 can be a UWB tag and a UWB antenna. The UWB tag includes a UWB radio frequency chip, which is driven by a highly stable clock and generates baseband pulses with extremely short durations (e.g., 2 nanoseconds) according to a specific repetition period (e.g., 1 million times per second). These baseband pulses are modulated to a specified UWB frequency band (e.g., a center frequency of 6.5 GHz), amplified by a power amplifier, and then radiated omnidirectionally into space through the UWB antenna. This pulse signal encodes the unique ID information of the remote control device 200. Obtaining this pulse signal facilitates subsequent positioning of the remote control device 200.

[0070] Please see Figure 9 , Figure 9 This is a second structural block diagram of the remote control device 200 in the location display system provided in this application embodiment. The remote control device 200 further includes a detection module 220, a communication module 230, and a second control module 240. Both the detection module 220 and the communication module 230 are connected to the second control module 240. The remote control device 200 collects attitude data information through the detection module 220 and outputs the attitude data information to the display device 100 through the communication module 230. As one embodiment, the detection module 220 includes an attitude sensor, which acquires the motion acceleration and angular velocity of the remote control device 200 and outputs the motion acceleration and angular velocity to the second control module 240, which then sends them to the display device 100 through the communication module 230. The communication module 230 includes a second Bluetooth module, which is used to transmit the motion acceleration and angular velocity to the first Bluetooth module.

[0071] Please see Figure 10 , Figure 10 This is a third structural block diagram of the remote control device 200 in the location display system provided in this application embodiment. In some embodiments, the remote control device 200 further includes a prompting module 250. The remote control device 200 also receives a boundary trigger command output by the display device 100 through the communication module 230, and controls the prompting module 250 to output corresponding prompt information according to the boundary trigger command. As one embodiment, the prompting module 250 includes a vibration motor, which can be controlled by the second control module 240 to perform vibration in different modes according to the boundary trigger command received by the second Bluetooth module, so as to achieve the function of alarm prompting.
