[0054] Embodiment 1

[0055] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of an identification and control method for a dual-view and dual-control display screen provided in Embodiment 1 of the present invention. This method is applicable to the scenario where a user uses a dual-view and dual-control display screen, and the dual-view and dual-control display screen can display different contents at two different viewing angles. This method is executed by the identification and control system of the dual-view and dual-control display screen, and this system can be implemented by software and / or hardware and integrated inside the dual-view and dual-control display screen. The method specifically includes the following steps:

[0056] S1. Receive the frequency signal conducted by the user's body; the frequency signal is generated by a wearable device worn on the user's body; the frequency signals generated by different wearable devices are different.

[0057] It should be noted that in the application scenario of this dual-view dual-control display screen, the user wears wearable devices. These wearable devices have the function of generating specific frequency signals, and the frequency signals generated by different wearable devices are different. For example, it may be any one of wearable bracelets, watches, or rings. Each device is designed to emit a unique frequency signal, just like everyone has a unique fingerprint. The frequency signal is the identifier for distinguishing different wearable devices.

[0058] The frequency signal generated by the wearable device is conducted to the dual-view dual-control display screen through the user's body. This is because the human body can be used as a good signal conduction medium. When the user touches the display screen, the frequency signal can be transmitted from the wearable device to the receiving device of the display screen. This conduction method provides a basis for subsequent signal recognition and user recognition.

[0059] S2. According to the characteristics of the frequency signal, identify which wearable device generates the frequency signal, so as to identify which user is performing the touch, and determine it as the target user.

[0060] It should be noted that each frequency signal generated by the wearable device has its unique characteristics. The recognition control system of the dual-view dual-control display screen has the ability to analyze these frequency signal characteristics. For example, the system can pre-store the frequency signal characteristic templates of each wearable device. When a new frequency signal is received, by comparing it with these templates, it can be determined which template the signal best matches.

[0061] Since different wearable devices are correspondingly associated with different users (for example, user A wears wearable device A, and user B wears wearable device B), after identifying which wearable device generates the frequency signal, it can be determined which user is performing the touch operation, and this user is determined as the target user. This step realizes the accurate identification of the touch-operating user and avoids the confusion that may occur when multiple users operate simultaneously.

[0062] S3. In response to the touch operation of the target user, control the display content of the corresponding perspective of the target user.

[0063] It should be noted that after determining the target user, the recognition control system of the dual-view dual-control display screen will monitor the touch operations of the target user in real time. These touch operations can be various common touch gestures such as clicking, swiping, and zooming. The system can accurately capture these operations and convert them into corresponding control instructions.

[0064] The dual-view and dual-control display screen has two different viewing angles and can display different contents respectively. The system applies the control instructions corresponding to the touch operation to the display content of the viewing angle corresponding to the target user according to the identity of the target user. For example, if the target user A corresponds to the left viewing angle of the display screen, then the touch operation of user A will only affect the content displayed on the left viewing angle, such as switching the picture on the left viewing angle, adjusting the video playback progress on the left viewing angle, etc., and will not affect the content displayed on the right viewing angle. This ensures that the touch operation of each user only affects the display content of its corresponding viewing angle, avoids misoperations, and improves the interaction performance and user experience.

[0065] Please refer to Figure 2 , in an implementation manner of this embodiment, S2 specifically includes:

[0066] S2.1. Preprocess the frequency signal.

[0067] It should be noted that in the actually received frequency signal, there are often various interferences and noises, which will affect the accuracy of subsequent signal feature extraction and analysis. The purpose of preprocessing is to remove these interferences and noises, improve the signal quality, and create good conditions for subsequent feature extraction and analysis.

[0068] Common preprocessing methods:

[0069] Filtering: Remove high-frequency noise or low-frequency interference in the signal through a filter. For example, using a low-pass filter can remove high-frequency noise and make the signal smoother; using a high-pass filter can remove low-frequency interference and highlight the useful information in the signal.

[0070] Amplification: If the amplitude of the received signal is too small, it may affect the effect of subsequent processing. Amplify the signal through an amplifier to increase the amplitude of the signal and make it within a suitable processing range.

[0071] Sampling and quantization: Convert the continuous analog signal into a discrete digital signal for subsequent digital processing. Sampling refers to taking values of the analog signal at a certain time interval, and quantization refers to converting the amplitude value of the sampled analog signal into the discrete value of the digital signal.

[0072] S2.2. Extract features from the preprocessed frequency signal, and the features of the frequency signal include at least one of frequency, phase, and amplitude.

[0073] It should be noted that the features of the frequency signal are the key information for distinguishing different wearable devices. By extracting features from the preprocessed signal, feature parameters that can represent the essence of the signal can be extracted, and these feature parameters will be used for subsequent feature matching and user identification.

[0074] Frequency is the number of vibrations of a signal per second, and the frequencies of the frequency signals generated by different wearable devices may be different. For example, the signal frequency generated by wearable device A is 100 Hz, and the signal frequency generated by wearable device B is 200 Hz.

[0075] Phase represents the state of a signal at a certain moment, reflecting the starting position and changing trend of the signal. There may be differences in the signal phases of different wearable devices, and such differences can also be used as a basis for identifying users.

[0076] Amplitude represents the strength of a signal, and the signal amplitudes of different wearable devices may be different. For example, the signal amplitude generated by wearable device A is larger, and the signal amplitude generated by wearable device B is smaller.

[0077] In this embodiment, time-domain analysis methods, frequency-domain analysis methods, time-frequency analysis methods, etc. can be used to extract the features of the signal. For example, the Fourier transform is used to convert the time-domain signal into a frequency-domain signal to extract the frequency features of the signal; wavelet transform is used for time-frequency analysis to extract the time-frequency features of the signal.

[0078] S2.3. Analyze the features of the frequency signal through a feature matching algorithm to identify which wearable device generated the frequency signal, so as to identify which user is performing the touch, and determine it as the target user.

[0079] It should be noted that the role of the feature matching algorithm is to compare the extracted features of the frequency signal with the feature templates of the pre-stored legal wearable devices, find the most matching template, so as to determine which wearable device generated the frequency signal, and then identify the corresponding user.

[0080] Common feature matching algorithms:

[0081] Euclidean distance algorithm: Calculate the Euclidean distance between the extracted feature vector and the template feature vector. The smaller the distance, the higher the matching degree. Select the template with the smallest distance as the matching result.

[0082] Cosine similarity algorithm: Calculate the cosine similarity between the extracted feature vector and the template feature vector. The closer the cosine similarity is to 1, the higher the matching degree. Select the template with the largest cosine similarity as the matching result.

[0083] After determining the wearable device corresponding to the frequency signal through the feature matching algorithm, since there is a one-to-one correspondence between the wearable device and the user, it is possible to determine which user is performing the touch operation and determine it as the target user.

[0084] In summary, in this embodiment, interference and noise are removed through preprocessing, improving the quality of the signal; feature parameters representing the essence of the signal are extracted through feature extraction; and the extracted features are compared with the templates stored in advance through a feature matching algorithm, realizing accurate identification of the wearable device and the user. This series of steps improves the accuracy of user identification and avoids misidentification.

[0085] Please refer to Figure 3 , in an implementation manner of this embodiment, S3 specifically includes:

[0086] S3.1. Detect the type of touch operation of the target user, where the type of touch operation includes at least one of click, swipe, long press, and gesture operation.

[0087] It should be noted that the definitions of each type of touch operation are as follows:

[0088] Click: The user quickly touches the surface of the display screen with a finger and then immediately lifts it, usually used to select an option, open an application, or trigger a specific function. For example, on the desktop interface of a smartphone, clicking on an application icon can open the application.

[0089] Swipe: The user moves a finger on the surface of the display screen along a certain direction, which can be used to scroll a page, switch pictures, or adjust parameters, etc. For example, in web browsing, swiping a finger up can view more content; in a picture viewing application, swiping a finger left or right can switch different pictures.

[0090] Long press: The user holds a finger on the surface of the display screen for a period of time (usually exceeding a certain threshold, such as 500 milliseconds), often used to pop up a menu, enter an editing mode, or perform a specific operation. For example, in a text editor, long pressing on a piece of text can pop up menu options such as copy, paste, and delete.

[0091] Gesture operation: A relatively complex touch operation, usually completed by multiple fingers collaborating to perform specific actions, such as zooming, rotating, two-finger swiping, etc. In a map application, pinching two fingers together can zoom out the map, and spreading two fingers apart can zoom in the map; in a picture editing application, rotating two fingers can adjust the angle of the picture.

[0092] S3.2. Generate a corresponding control instruction according to the type of touch operation.

[0093] It should be noted that different types of touch operations correspond to different control requirements, so corresponding control instructions need to be generated according to the type of touch operation. A control instruction is a command used to instruct the dual-view dual-control display screen to perform a specific operation, and it contains information such as the target object of the operation and the operation method.

[0094] Specific corresponding relationships:

[0095] Click operation: Generate control instructions for selecting, opening, or triggering functions. For example, when a click operation is detected, an instruction to open a certain application or select a certain menu item is generated.

[0096] Swipe operation: Generate control instructions for scrolling, switching, or adjusting parameters. For example, during page browsing, an instruction to scroll up or down is generated according to the swipe direction; during picture browsing, an instruction to switch to the previous or next picture is generated according to the swipe direction.

[0097] Long press operation: Generate instructions for popping up a menu, entering an editing mode, or performing a specific operation. For example, in a text editor, after long pressing on text, instructions for popping up menu options such as copy, paste, and delete are generated.

[0098] Gesture operation: Generate corresponding control instructions for zooming, rotating, two-finger swiping, etc. For example, in a map application, a two-finger pinch operation generates an instruction to zoom out the map, and a two-finger spread operation generates an instruction to zoom in the map.

[0099] S3.3. Control the display content of the corresponding perspective of the target user according to the control instruction.

[0100] It should be noted that after the control system of the dual-view dual-control display screen receives the control instruction, it will perform corresponding operations on the display content of the corresponding perspective of the target user according to the target object and operation method information in the instruction. For example, if the control instruction is to open a certain application, the control system will call the corresponding application and display it on the corresponding perspective of the target user; if the control instruction is to scroll the page, the control system will adjust the display position of the display content to achieve the page scrolling effect.

[0101] Since the dual-view dual-control display screen has two different perspectives and can display different contents respectively. When executing the control instruction, the control system will apply the control instruction to the display content of the corresponding perspective of the target user according to the identity of the target user, ensuring that the touch operation of each user only affects the display content of its corresponding perspective. For example, if target user A corresponds to the left perspective of the display screen and target user B corresponds to the right perspective of the display screen, then the touch operation of user A will only affect the display content of the left perspective, and the touch operation of user B will only affect the display content of the right perspective.

[0102] In summary, in this embodiment, by accurately detecting the type of touch operation and generating the corresponding control instruction, precise control of the display content of the dual-view dual-control display screen is achieved. Users can conveniently and quickly operate the display screen through different touch operation methods, improving the efficiency and flexibility of interaction.

[0103] The touch operation of each user only affects the displayed content of their corresponding perspective, avoiding misoperations and interference, enabling users to focus more on the content of their own perspective. At the same time, the rich types of touch operations and corresponding control instructions provide users with more diverse interaction methods, enhancing the user experience.

[0104] Although terms such as frequency signals and features are used more frequently in this application, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0105] An identification and control method for a dual-view and dual-control display screen provided by an embodiment of the present invention realizes accurate identification of touch-operating users by receiving frequency signals generated by wearable devices and conducted through the user's body, effectively solving the problem of misoperations caused by inaccurate user identification in the prior art, being able to accurately distinguish the touch operations of different users, ensuring that the touch operation of each user only affects the displayed content of their corresponding perspective, thereby significantly improving the interaction performance and user experience of the dual-view and dual-control display screen.
