Detailed Implementation

[0018] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure 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 disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] A first aspect of this disclosure is to provide a display method, such as... Figure 1 As shown, the method includes the following steps: Step 101: Send a probe wave signal.

[0020] This method is applicable to electronic devices with display and signal transmission / reception functions, such as mobile phones, tablets, smart screens, and wearable devices. These electronic devices are typically equipped with signal transmitting devices such as speakers, horns, millimeter-wave antennas, and radio frequency antennas. In this embodiment, the electronic device executing this method is taken as the target device.

[0021] In this step, the target device emits a probe wave signal through its built-in signal transmitting device. The probe wave signal can be either an acoustic signal or an electromagnetic signal, and the type of probe wave signal matches the activated signal transmitting device. Specifically, the target device can emit an acoustic signal as a probe wave signal through a speaker or horn, or it can emit an electromagnetic signal as a probe wave signal through its built-in antenna module.

[0022] Step 102: Receive the echo signal generated by the transmission of the probe wave signal.

[0023] After the target device's signal transmitting device emits a probe wave signal, the signal is reflected when it encounters obstacles such as a human body during its propagation through space, generating an echo signal that matches the type of the probe wave signal. The method of receiving the echo signal corresponds one-to-one with the type of probe wave signal emitted. That is, if the emitted probe wave signal is an acoustic signal, the reflected echo signal is an acoustic echo signal, which is received by the microphone built into the target device; if the emitted probe wave signal is an electromagnetic wave signal, the reflected echo signal is an electromagnetic echo signal, which is received by the antenna module built into the target device.

[0024] Step 103: Determine whether the target object exists based on the echo signal.

[0025] After the target device's signal receiving device acquires the echo signal, it transmits the echo signal to the data processing module built into the target device. The data processing module first performs preprocessing operations such as filtering and noise reduction on the acquired echo signal. After signal preprocessing, it can combine liveness detection algorithms, signal feature comparison, and other detection methods to analyze and judge the fluctuation characteristics of the echo signal, and identify whether there are live target objects such as users within the detection range.

[0026] Step 104: If a target object exists, determine the relative angle information between the target object and the initial display screen of the target device.

[0027] If a target object is determined to exist within the detection range, the deflection angle of the target object relative to the initial display screen of the target device (i.e., the display screen currently output by the target device) is obtained, and this angle is used as the relative angle information between the target object and the initial display screen.

[0028] For example: taking the vertical direction in space as the 0° reference reference; when the target object is facing the screen and the device's initial display screen is placed in the correct orientation, the relative deflection angle between the target object's viewing direction and the reference direction of the initial display screen is 0°; when the target object's head is tilted to the side, and the viewing direction is shifted by 30° relative to the initial orientation, and the orientation of the device's initial display screen remains unchanged, the relative deflection angle between the two is 30°.

[0029] Step 105: Based on relative angle information, determine the target display screen of the target device; the display direction of the target display screen is adapted to the orientation of the target object.

[0030] After obtaining the relative angle information, it is compared with a preset angle adjustment threshold. This angle adjustment threshold is used to define the critical conditions for image correction: if the relative angle information is greater than or equal to the threshold, it means that the target object's viewing direction deviates significantly from the reference orientation of the initial displayed image, which can easily lead to a poor viewing experience.

[0031] At this point, the display orientation of the initial display needs to be corrected and adjusted. This can be achieved by updating the display transformation matrix to rotate the image. The image generated after rotation and correction is the target display image. The display orientation of this target display image is adapted to the viewing direction of the target object, effectively improving viewing comfort.

[0032] Regardless of changes in the orientation of the target device or a shift in the target object's viewing direction, this solution can maintain the screen display facing the target object's view without requiring the user to manually adjust their viewing angle or move the device.

[0033] The display method disclosed in this embodiment transmits a probe wave signal and receives the reflected echo signal. Based on the echo signal, it determines whether a target object exists within the detection range. When a target object is detected, it determines the relative angle information between the target object and the current display screen (initial display screen) of the target device. Then, based on this relative angle information, it adjusts the display direction of the current display screen to obtain the adjusted display screen (target display screen). This solution can adaptively adjust the screen direction according to the deflection angle between the target object and the display screen, ensuring that the screen display direction always matches the target object's viewing direction, improving viewing angle matching and user visual experience.

[0034] Existing conventional solutions generally use attitude sensing components such as gravity sensors and gyroscopes to switch between horizontal and vertical display modes by detecting the device's own attitude. These devices rely on gravity components to complete attitude recognition, and can only be triggered when the device's orientation changes; when the device's orientation remains unchanged, they cannot adaptively correct the display direction, which has significant limitations.

[0035] This embodiment does not require a gravity-based attitude detection architecture and is not limited by the device's own placement posture. It can adaptively adjust the screen according to the user's posture, making it applicable to a wider range of scenarios. This display method is particularly suitable for electronic devices where the screen and host can be separated: after the physical connection between the screen and the host is broken, the screen's orientation is flexible and can easily lead to a mismatch between the screen orientation and the user's viewing direction. This solution can correct the display orientation in real time. When the screen and host remain connected, the overall placement of the device is relatively fixed. Even if the user's posture shifts, the screen orientation can be adjusted in time to ensure that the screen always adapts to the user's viewing direction.

[0036] Meanwhile, this solution can utilize existing hardware resources such as speakers, microphones, and antenna modules in the target device to achieve sound wave transmission and reception and orientation perception, without the need to add additional attitude sensing components such as gravity sensors and gyroscopes. The hardware structure design is simpler, effectively reducing the overall hardware development and material costs of the device.

[0037] In another embodiment of this disclosure, determining the relative angle information between the target object and the initial display screen of the target device includes: acquiring the spatial positioning information of the target object; establishing a spatial calibration coordinate system based on the display direction of the initial display screen; mapping the spatial positioning information of the target object to the spatial calibration coordinate system to obtain the relative angle information between the target object and the initial display screen of the target device.

[0038] First, spatial positioning information of the target object is collected. This information characterizes the target object's spatial orientation. Using the initial display orientation as a reference, a spatial calibration coordinate system is constructed. The direction parallel to the horizontal edge of the screen is set as the horizontal axis, and the direction parallel to the vertical edge of the screen is set as the vertical axis. This spatial calibration coordinate system serves as a unified reference system for calculating relative orientation. For its specific structure, please refer to the appendix. Figure 2 .

[0039] The collected spatial positioning information of the target object is then transformed and mapped to the spatial calibration coordinate system, as exemplified by the following structure: Figure 3 As shown, the angle between the spatial positioning information and the horizontal or vertical axis of the coordinate system is obtained, and this angle value is used as the relative angle information of the target object relative to the initial display screen of the target device. The solution in this embodiment constructs a spatial calibration coordinate system based on the display direction of the initial display screen, which can accurately quantify the deflection angle (relative angle information) of the target object's viewing direction relative to the screen image.

[0040] In another embodiment of this disclosure, obtaining the spatial positioning information of the target object includes: determining the contour features of the target object based on the echo signal; determining the preset positioning point corresponding to the target object based on the contour features of the target object; constructing the head baseline and shoulder baseline corresponding to the target object based on the preset positioning point; and obtaining the spatial positioning information of the target object based on the head baseline and shoulder baseline.

[0041] First, the acquired echo signals are analyzed to extract characteristic parameters such as time delay, phase, and reflection intensity. Based on these extracted parameters, the contour features of the target object are constructed, representing its overall spatial shape distribution. Specifically, the propagation distance of the probe wave can be calculated from the time delay value, and the three-dimensional spatial coordinates of each reflection point are obtained by combining the probe wave emission angle. The reflection intensity at each location is used to distinguish the human body area from background obstacles, eliminating low-intensity clutter noise. All valid human body reflection coordinate points are collected, and surface interpolation or point cloud mesh fitting is used to generate a continuous closed point cloud contour. This point cloud contour is the contour feature of the target object, capable of completely reconstructing the spatial morphological distribution of the human head, torso, and shoulders.

[0042] After acquiring the contour features, preset positioning points on the contour features are identified and calibrated. These preset positioning points are pre-defined feature points within the human contour that accurately represent the human posture and orientation, specifically including the head center feature point, left and right shoulder feature points, etc. Specifically, after contour extraction, the contour is divided into head and shoulder regions according to the human body structure. The real-time acquired contour is matched and compared with a pre-stored standard human contour template. The geometric center of the contour in the head region is calculated and used as the head center feature point. The extreme coordinates of the two protruding positions on the left and right sides of the contour in the shoulder region are obtained and used as the left and right shoulder feature points, thus completing the calibration of the preset positioning points.

[0043] Subsequently, based on the calibrated head and shoulder feature points, straight line fitting is performed to construct the head and shoulder baselines corresponding to the target object. For example, refer to... Figure 4 As shown. Finally, the constructed head and shoulder baselines are used as spatial positioning references, which serve as the spatial positioning information for the target object.

[0044] The solution in this embodiment, by reconstructing the contour features of the human body and marking easily locating baselines in the contour features, can accurately characterize the spatial positioning information of the target object, providing stable and reliable technical support for the logical determination and adaptive adjustment of the subsequent display direction.

[0045] In another embodiment of this disclosure, determining the target display screen of the target device based on relative angle information includes: comparing the relative angle information with an angle adjustment threshold to obtain a comparison result; if the comparison result indicates that the relative angle information is greater than or equal to the angle adjustment threshold, adjusting the display direction of the initial display screen to obtain the target display screen of the target device; if the comparison result indicates that the relative angle information is less than the angle adjustment threshold, using the initial display screen as the target display screen of the target device.

[0046] A pre-configured angle adjustment threshold is set, which is the critical angle value for determining whether to correct the image orientation. The calculated relative angle information is compared with this angle adjustment threshold, and the corresponding comparison result is output.

[0047] When the comparison result shows that the relative angle information is greater than or equal to the angle adjustment threshold, it indicates that the target object's posture deviates significantly from the reference orientation of the initial display screen, making the viewing image appear tilted and unnatural. In this case, the display orientation of the initial display screen is corrected and adjusted by rotating the image through a transformation matrix to generate a target display screen that adapts to the viewing direction.

[0048] When the comparison result shows that the relative angle information is less than the angle adjustment threshold, it means that the orientation deviation between the two is small and will not affect the normal viewing effect. There is no need to change the display direction of the initial screen, and the initial display screen can be directly regarded as the target display screen.

[0049] This embodiment introduces preset angle adjustment conditions as the basis for determining the adjustment trigger, which can achieve precise triggering and reasonable control of screen display direction adjustment. It can effectively avoid frequent screen switching caused by small angle fluctuations, reduce unnecessary ineffective adaptation actions, and significantly improve the operational stability and rationality of screen display adjustment.

[0050] In another embodiment of this disclosure, adjusting the original display screen of the target device to obtain the target display screen includes: matching relative angle information with display direction matching rules to obtain angle adjustment information; and adjusting the display direction of the initial display screen based on the angle adjustment information to obtain the target display screen of the target device.

[0051] The device retrieves the pre-configured display orientation matching rules, which are used to establish a one-to-one mapping relationship between relative angle information and angle adjustment information. This allows for matching the corresponding angle adjustment information based on different relative angle information, thereby determining the screen rotation parameters.

[0052] After obtaining the relative angle information between the target object and the initial display screen, this relative angle information is compared with a preset display direction matching rule to determine the corresponding angle adjustment information. The angle adjustment information refers to the rotation angle value required to adjust the initial display screen to eliminate viewing deviation and adapt to the user's viewing angle. Finally, based on this angle adjustment information, the display direction of the initial display screen is rotated and corrected to generate a target display screen that matches the viewing direction of the target object.

[0053] For example, the specific determination logic can be referred to Figure 5 Based on the spatial calibration coordinate system established earlier, the device detection area is divided into multiple different angle threshold intervals according to the angle range. Each threshold interval is pre-bound with a unique corresponding angle adjustment information. In this embodiment, the interval division and matching are performed with counterclockwise as the positive angle direction: when the relative angle information is in the upward threshold interval of 0°-45°, the positive display adaptation rule is matched, and the corresponding angle adjustment information is 45°; when the relative angle information is in the upper left change threshold interval of 45°-90°, the corresponding angle adjustment information is 90°, and so on.

[0054] It should be noted that the above interval division method is only an illustrative example and is not a limitation of this solution. In practical applications, more and smaller angle threshold intervals can be further refined according to the display accuracy requirements to achieve high-precision image adjustment. For example, 0°~10° can be set as an independent threshold interval. When the detected relative angle information falls into this interval, a 10° angle adjustment information is obtained, achieving accurate correction of small angle deviations and further improving image adaptation accuracy and user viewing experience.

[0055] The solution in this embodiment introduces a unified display direction matching rule to determine the angle adjustment information, which can realize the standardized and regular adaptation and adjustment of the screen display direction, making the screen adjustment logic clearer and the adaptation result more regular, effectively improving the rationality and consistency of screen viewing angle matching.

[0056] In another embodiment of this disclosure, determining whether a target object exists based on the echo signal includes: extracting features from the echo signal to obtain dynamic fluctuation features corresponding to the echo signal; determining whether a live signal exists in the echo signal based on the dynamic fluctuation features; if a live signal exists, determining that a target object exists; if no live signal exists, determining that no target object exists.

[0057] First, the original echo signal is processed using time-domain analysis. The amplitude fluctuations and phase shifts of the echo signal are extracted frame by frame to obtain the signal's time-domain fluctuation characteristics. The reflected echoes from stationary obstacles exhibit relatively constant amplitude and phase with no temporal fluctuations. However, human breathing, minor body movements, and posture adjustments continuously disturb the propagation path of the probe wave, causing continuous temporal jitter and shifts in the echo amplitude and phase. Therefore, the time-domain fluctuation characteristics can preliminarily distinguish between static objects and slightly moving targets.

[0058] Further frequency domain transformation is performed on the time-domain processed echo signal to convert the time-domain fluctuation signal into frequency distribution characteristics, extracting low-frequency perturbation components to obtain complete dynamic fluctuation characteristics. The perturbation corresponding to human body micro-movements is a low-frequency, regular, weak frequency signal, while environmental clutter and equipment noise are mostly high-frequency random signals. Stationary objects have no effective low-frequency perturbation components. Frequency domain filtering can further filter out interference and purify the characteristic information corresponding to human body micro-movements.

[0059] After feature extraction, the final dynamic fluctuation features are matched with a pre-constructed human liveness feature template. If the dynamic fluctuation features contain amplitude temporal fluctuations, phase shifts, and low-frequency perturbation components consistent with the micro-movements and small changes in posture of the human body, and the matching degree reaches a preset threshold, then it is determined that a liveness signal exists in the echo signal, and a human target object exists within the detection range. If the echo signal has no temporal fluctuation features, no effective low-frequency micro-movement components, and its overall features are consistent with the echo characteristics of a static obstacle, and cannot match the liveness template, then it is determined that no liveness signal exists, and no target object exists within the detection range.

[0060] The solution in this embodiment uses the dynamic fluctuation characteristics of the echo signal for liveness detection, which can effectively distinguish between live human bodies and interference signals from still objects, thereby improving the accuracy and reliability of target object detection.

[0061] In another embodiment of this disclosure, transmitting the probe wave signal includes: transmitting the probe wave signal through a signal transmitting device configured in the target device.

[0062] The signal transmitting device is an existing integrated component of the target equipment, requiring no additional hardware. The device itself possesses the capability to directionally transmit probe waves and stably output probe signals, similar to a speaker or antenna. This solution utilizes existing equipment components to transmit probe waves without adding new sensing or detection hardware, effectively reducing equipment modification costs and structural complexity, and enhancing the feasibility and versatility of the solution.

[0063] A second aspect of this disclosure is to provide a display device, such as... Figure 6 As shown, the device includes: Signal transmitting module 601 is used to transmit probe wave signals; Receiver module 602 is used to receive the echo signal generated by the reflection of the probe wave signal; The determination module 603 is used to determine whether a target object exists based on the echo signal; The determination module 603 is used to determine the relative angle information between the target object and the initial display screen of the target device if the target object exists. The adjustment module 604 is used to determine the target display screen of the target device based on the relative angle information; the display direction of the target display screen is adapted to the orientation of the target object.

[0064] In another embodiment of this disclosure, the adjustment module 604 is further configured to compare the relative angle information with the angle adjustment threshold to obtain a comparison result; if the comparison result indicates that the relative angle information is greater than or equal to the angle adjustment threshold, the display direction of the initial display screen is adjusted to obtain the target display screen of the target device; if the comparison result indicates that the relative angle information is less than the angle adjustment threshold, the initial display screen is used as the target display screen of the target device.

[0065] In another embodiment of this disclosure, the determination module 603 is further configured to obtain the spatial positioning information of the target object; establish a spatial calibration coordinate system based on the display direction of the initial display screen; and map the spatial positioning information of the target object to the spatial calibration coordinate system to obtain the relative angle information between the target object and the initial display screen of the target device.

[0067] In another embodiment of this disclosure, the adjustment module 604 is further configured to obtain a preset display direction matching rule; match the relative angle information with the display direction matching rule to obtain angle adjustment information; and adjust the display direction of the initial display screen based on the angle adjustment information to obtain the target display screen of the target device.

[0068] In another embodiment of this disclosure, the determination module 603 is further configured to extract features from the echo signal to obtain the dynamic fluctuation features corresponding to the echo signal; based on the dynamic fluctuation features, determine whether there is a live signal in the echo signal; if there is a live signal, determine that there is a target object; if there is no live signal, determine that there is no target object.

[0069] In another embodiment of this disclosure, the signal transmitting module 601 is further configured to transmit a probe wave signal via a signal transmitting device configured in the target device.
