[0022] 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0024] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0026] AR glasses are electronic devices that can overlay real-world scenes with virtual images. The lenses of AR glasses are transparent, allowing a clear view of the external environment. Furthermore, the lenses can project light from the virtual image to be displayed onto the user's eyes, enabling them to simultaneously see both the external environment and the virtual image. For example... Figure 1 As shown. AR glasses have a structure similar to ordinary glasses, including lenses, frames, temples, and nose pads, for example... Figure 2 As shown, both left and right lenses can project light onto the human eye to display the virtual image to be shown. The image is then combined by the human eye to achieve display.

[0027] In addition, the display of AR glasses also involves various other aspects such as the color of the content display and the depth of field of the content display. Currently, the display of AR glasses is usually controlled by pre-set rules, which results in a single and inflexible display method.

[0028] To address the aforementioned issues, embodiments of this application provide a display control method, apparatus, system, and storage medium for a head-mounted display device, aimed at improving the display flexibility of the head-mounted display device and enhancing the user experience.

[0029] Please see Figure 3 , Figure 3 This is a schematic flowchart illustrating a display control method for a head-mounted display device according to an embodiment of this application. This method can be applied to a display control device for a head-mounted display device, or to a control system for a head-mounted display device including the display control device, to control the intelligent display of the head-mounted display device and solve the problems of limited and inflexible display modes. The head-mounted display device includes, but is not limited to, AR glasses, VR (Virtual Reality) glasses, and other similar devices.

[0030] Before detailing the display control method of the head-mounted display device, the control system of the head-mounted display device will be introduced first. The control system of the head-mounted display device can be an external system of the head-mounted display device, or the control system of the head-mounted display device can be set in the head-mounted display device; no specific limitation is made in this application.

[0031] For example, such as Figure 4 As shown, the control system 1000 of the head-mounted display device includes at least one type of sensor device 100 and a display control device 200 for the head-mounted display device. The sensor device 100 includes, but is not limited to, IMU (Inertial Measurement Unit), photosensors, depth sensors, grayscale cameras, color cameras, eye-tracking devices, microphones, etc., and is wirelessly / wired connected to the display control device 200 of the head-mounted display device. The display control device 200 includes, but is not limited to, various types of electronic devices such as smartphones, tablets, desktop computers, and personal digital assistants. The head-mounted display device 2000 is wirelessly / wired connected to the display control device 200, and includes, but is not limited to, AR glasses, VR glasses, etc.

[0032] The sensor device 100 collects display-related information, including but not limited to IMU information, camera capture information, depth information, eye-tracking information, and photosensitivity information. The display control device 200 of the head-mounted display device obtains the IMU information, camera capture information, depth information, eye-tracking information, and photosensitivity information collected by the sensor device 100. Based on this display-related information, it determines the display characteristic values ​​corresponding to the display characteristics of the head-mounted display device 2000. The display characteristics of the head-mounted display device 2000 include, but are not limited to, electrochromic properties, content display depth of field, content display color, and content output format, including display-to-speech and speech-to-display conversion. The display control device 200 of the head-mounted display device controls the head-mounted display device 2000 to perform intelligent display based on the determined display characteristic values ​​corresponding to the electrochromic properties, content display depth of field, content display color, and content output format.

[0033] For example, taking the AR glasses 2000 head-mounted display device as an example, such as Figure 5 As shown, IMU 101 collects IMU information corresponding to the AR glasses, camera 102 collects camera shooting information, depth sensor 103 collects depth information, photosensitive device 104 collects photosensitive information of the current environment, and eye-tracking device 105 collects the user's eye-tracking information. The collected IMU information, photosensitive information, depth information, camera shooting information, eye-tracking information, and other display-related information are transmitted to the display control device 200 of the head-mounted display device. The display control device 200 determines the corresponding electrochromic characteristic values, content display depth-of-field characteristic values, content display color characteristic values, and voice / display conversion based on the IMU information, photosensitive information, depth information, camera shooting information, and eye-tracking information. The display control device 200 then controls and adjusts the AR glasses' electrochromic properties, content display depth of field, content display color, and content display to voice / voice to display conversion based on these display characteristic values.

[0034] It should be understood that the aforementioned control system 1000 for the head-mounted display device is merely a specific example and does not constitute a specific limitation on the control system of the head-mounted display device in this application embodiment. The control system of the head-mounted display device in this application embodiment can also be implemented in other specific ways. In other implementations, the control system of the head-mounted display device can be more... Figure 4 and Figure 5 The control system 1000 of the head-mounted display device shown may have more or fewer components.

[0035] like Figure 3As shown, the display control method for the head-mounted display device in this application specifically includes steps S101 to S103.

[0036] S101. Obtain at least one display-related information.

[0037] For example, display-related information refers to information that affects the display characteristics of head-mounted display devices, such as electrochromic properties, content display depth, and content display color. Display-related information includes, but is not limited to, IMU information, camera shooting information, depth information, eye-tracking information, and photosensitivity information.

[0038] In some embodiments, obtaining at least one display-related information includes: obtaining the display-related information collected by at least one type of sensor device.

[0039] Sensor devices include, but are not limited to, IMUs, photosensors, depth sensors, grayscale cameras, color cameras, eye-tracking devices, and microphones. For example, the IMU collects information corresponding to the head-mounted display device, the camera collects image information, the depth sensor collects depth information, the photosensor collects ambient light information, and the eye-tracking device collects the user's eye movement information, thus obtaining various display-related information collected by each sensor device.

[0040] S102. Based on at least one of the aforementioned display-related information, determine a first set of display characteristic values ​​corresponding to the display characteristics of the head-mounted display device, wherein the display characteristics include at least one of electrochromic properties, content display depth of field, content display color, and content output format.

[0041] Display-related information affects the display characteristics of head-mounted displays, such as electrochromic properties, depth of field, and color reproduction. It's important to note that there isn't a one-to-one correspondence between the display characteristics and display-related information. Some display characteristics may be affected by only one type of display-related information, while others may be influenced by a combination of multiple types. Different display-related information corresponds to different display characteristic values. For example, different photosensitivity information results in different electrochromic characteristic values. It should be noted that a display characteristic value can be a specific numerical value or a characteristic value.

[0042] In some embodiments, determining a first set of display characteristic values ​​corresponding to the display characteristics of the head-mounted display device based on at least one of the display-related information includes: querying a preset mapping relationship between display-related information and display characteristic values, obtaining display characteristic values ​​mapped by at least one of the display-related information, and determining the mapped display characteristic values ​​as the first set of display characteristic values.

[0043] For example, a mapping relationship between display-related information and display characteristic values ​​is pre-defined. This can be achieved by configuring a display characteristic fingerprint database, which includes multiple fingerprints, each representing a mapping relationship between a set of display-related information and a set of display characteristic values. Typically, the display characteristic fingerprint database is queried to find a set of display-related information that matches the obtained display-related information. The set of display characteristic values ​​mapped to this matching set of information is then determined as the display characteristic value currently corresponding to the head-mounted display device. For ease of description, this will be referred to as the first set of display characteristic values ​​below. The first set of display characteristic values ​​includes, but is not limited to, electrochromic characteristic values, depth-of-field characteristic values, color characteristic values, and content output format characteristic values.

[0044] The first set of display characteristic values ​​can be obtained directly by querying the mapping relationship, which is very convenient, fast and efficient, thereby achieving high efficiency in the display control of head-mounted display devices.

[0045] In some embodiments, determining a first set of display characteristic values ​​corresponding to the display characteristics of the head-mounted display device based on at least one of the display-related information includes: processing the at least one of the display-related information through a trained neural network model to obtain the first set of display characteristic values.

[0046] Before controlling the display of the head-mounted display device, a neural network model is first constructed based on random forest, XGboost (distributed gradient boosting library), CNN (Convolutional Neural Networks), RNN (Recurrent Neural Network), transformer (deep learning model based on self-attention mechanism), etc., and the constructed neural network model is trained by sample data to obtain a trained neural network model.

[0047] For example, fingerprints from a display feature fingerprint database can be used as training samples to train a neural network model, thereby obtaining a trained neural network model.

[0048] For example, for training samples of a neural network model, on the one hand, display-related information such as IMU information, camera capture information, depth information, eye-tracking information, and light-sensitive information are each encoded into vectors of corresponding lengths. For instance, an embedding vector of the corresponding length is obtained through network encoding. The lengths of the vectors corresponding to the various display-related information can be different.

[0049] On the other hand, display characteristics such as electrochromic properties, content display depth, content display color, and content output format are encoded and divided. For example, electrochromic properties are encoded into a first preset number (e.g., N) of categories, that is, a first preset number of electrochromic property values ​​are set; content display depth is encoded into a second preset number (e.g., M) of categories, that is, a second preset number of depth property values ​​are set; content display color is encoded into a third preset number (e.g., X) of categories, that is, a third preset number of color property values ​​are set; and content output format (text-to-speech output and speech-to-text-image output) is encoded into two categories, that is, a first output format property value and a second output format property value are set, wherein the first output format property value represents text-to-image output to speech output, and the second output format property value represents speech output to text-to-image output.

[0050] It should be noted that the specific values ​​of the first preset quantity, the second preset quantity, and the third preset quantity can be flexibly set according to the actual situation, and no specific restrictions are imposed in this application.

[0051] Therefore, a set of display characteristic values ​​corresponding to each display characteristic can generate a characteristic value vector. For a first preset quantity of N, a second preset quantity of M, and a third preset quantity of X, the value range of this vector is N×M×X×2. If the number of display characteristics increases, the dimension of the characteristic value vector also increases.

[0052] The data processed as described above is used as training samples (i.e., feature vectors can be used as training samples) and input into the neural network model for model training, thereby obtaining a trained neural network model.

[0053] After obtaining the relevant display information, simply call the trained neural network model to process the data and obtain the corresponding first set of display characteristic values. Compared to obtaining the first set of display characteristic values ​​by querying mapping relationships, the first set of display characteristic values ​​obtained based on neural network model processing is more accurate and reliable.

[0054] For example, a training period can be preset, and the neural network model can be trained automatically at regular intervals based on the training period to optimize the neural network model, thereby further improving the accuracy and reliability of obtaining the first set of display characteristic values.

[0055] In some embodiments, processing the at least one of the display-related information through a trained neural network model to obtain the first set of display characteristic values ​​includes: encoding each type of display-related information to obtain a corresponding encoding vector; inputting the obtained at least one encoding vector into the neural network model to output the first set of display characteristic values.

[0056] For example, the obtained IMU information, camera shooting information, depth information and other display-related information are encoded by the network to obtain the corresponding encoding vectors. The encoding vectors are used as the input of the neural network model and output the first set of display characteristic values, such as electrochromic characteristic values, depth characteristic values, color characteristic values, and content output form characteristic values.

[0057] S103. Control the display of the head-mounted display device according to the first set of display characteristic values.

[0058] After obtaining the first set of display characteristic values, the head-mounted display device is controlled and adjusted according to the corresponding display characteristics based on these values. For example, at least one of the following display characteristics may be controlled and adjusted: electrochromic, content display depth of field, content display color, and content output format.

[0059] For example, taking the display of AR glasses as an example, such as Figure 6 As shown, the obtained IMU information, camera capture information, depth information, and other display-related information are encoded through a network to obtain corresponding encoded vectors of length L1 (vector1), L2 (vector2), and L3 (vector3). These encoded vectors are then input into a neural network model, which outputs corresponding feature value vectors. These feature value vectors include, but are not limited to, electrochromic feature values, depth-of-field feature values, color feature values, and first / second output form feature values. Based on the feature value vectors output by the neural network model, the display characteristics of the AR glasses are controlled, including electrochromic properties, content display depth of field, content display color, and content-to-speech / speech-to-display conversion, intelligently adjusting the AR glasses' display. This allows the AR glasses to intelligently display different information based on their display characteristics in different application scenarios, improving the flexibility of the AR glasses' display and thus enhancing the user experience.

[0060] In some embodiments, after controlling the display of the head-mounted display device, the process includes: recording a second set of display characteristic values ​​corresponding to the display characteristics set by the user; and updating the neural network model based on the second set of display characteristic values.

[0061] In practical applications, users can manually adjust the electrochromic properties of the head-mounted display device, such as content display depth, content display color, and content-to-speech / speech-to-display conversion. Based on the user's actions, a set of display characteristic values ​​corresponding to the user-set display characteristics are recorded. For ease of distinction, the set of display characteristic values ​​set by the user will be referred to as the second set of display characteristic values ​​below.

[0062] The second set of display characteristic values ​​and the obtained display-related information are used as sample data and input into the neural network model to train and further optimize the neural network model. Using the optimized neural network model, more accurate and reliable display characteristic values ​​can be obtained, making the display of the head-mounted display device more in line with the user's preferences and habits, and further improving the user experience.

[0063] In the above embodiments, by acquiring at least one display-related information, a first set of display characteristic values ​​corresponding to the display characteristics of the head-mounted display device is determined based on the display-related information. The display characteristics include at least one of electrochromic, content display depth, content display color, and content output format. Based on the first set of display characteristic values, the display of the head-mounted display device is controlled, thereby realizing intelligent display of the head-mounted display device, improving the flexibility of the display of the head-mounted display device, and thus enhancing the user experience.
