[0091] Example 2

[0092] According to the central control system of a digital multimedia exhibition hall described in Example 1, the operation process of the lighting control unit includes the following steps:

[0093] Collect light data through light sensing sensors, and use digital filtering technology to dynamically filter the sensor data for noise;

[0094] Establish a scene library to associate different exhibition scenes with their corresponding lighting effects;

[0095] Train machine learning models based on the light sensing data and scene requirements of the exhibition space;

[0096] Establish a feedback mechanism to optimize the dynamic adjustment algorithm by monitoring user reactions and feelings;

[0097] Use three-dimensional lighting models to consider the position, angle and lighting range of lamps to simulate and adjust the overall lighting effects.

[0098] Specifically, light sensing sensors (such as photoresistors, photodiodes, etc.) are placed in the exhibition space. Digital filtering techniques (such as moving average filtering, median filtering, etc.) are used to process sensor data in real time to reduce the impact of noise. A database is created or a graphical user interface is used to store the lighting effects of different exhibition scenes together with their corresponding light sensing data. Relevant lighting parameters, such as brightness, color, gradient effects, etc., are specified for each scene. The model is trained using machine learning algorithms (such as neural networks, decision trees, etc.) using the annotated exhibition scene data and the corresponding light sensing data. The model must be able to predict appropriate lighting effects based on the current light sensing data and scene requirements. An integrated user feedback system can monitor user reactions and feelings through cameras, sound sensors, or user adjustment panels. The machine learning model is adjusted using these data to optimize the dynamic adjustment algorithm of the lighting effect. Based on the three-dimensional lighting model, a virtual lighting environment is established considering the position, angle, and lighting range of the lamps. The scene requirements are combined with the three-dimensional lighting model to simulate and adjust the overall lighting effect to ensure that the position and angle of the lamps have the expected impact on the lighting of the exhibition space.

[0099] The operation process of the multimedia display module includes the following steps:

[0100] Parse the instructions received from the central control module and load the necessary media resources;

[0101] Specifically, a command parser module is written in a programming language, which is responsible for parsing the commands sent by the central control module. By defining the command format and protocol, the parser can identify different types of commands, such as commands to load media resources. Once the command to load media resources is parsed, the system will call the corresponding resource loading module to load the required media resources such as images, videos, and audio.

[0102] Utilize scene modeling in virtual reality technology, use sensors and camera equipment to track the exhibition space in real time, and establish connections with head-mounted display devices, AR glasses or other display devices;

[0103] Specifically, a 3D scene model of the exhibition space is created with the help of a virtual reality engine (such as Unity3D, Unreal Engine, etc.). Real-time spatial tracking is performed using sensors (such as lidar, infrared sensors, etc.) and camera equipment to capture the user's position and posture in the exhibition space. By establishing a connection with a head-mounted display device, AR glasses or other display devices, real-time transmission of scene information is ensured so that virtual or augmented reality content can be dynamically adjusted.

[0104] Design interactive elements for virtual or augmented reality scenes, including gesture recognition and touch screen control;

[0105] Specifically, in a virtual reality scene, a gesture recognition algorithm (such as gesture recognition based on deep learning) is used to achieve real-time recognition of user gestures. At the same time, for display devices that support touch screens, a corresponding user interface is designed to allow users to interact through touch. For example, users can use gestures to navigate the virtual space, select display content, or perform more detailed operations through the touch screen.

[0106] Using real-time rendering technology, the position and appearance of virtual objects are dynamically adjusted according to the dynamic factors of the user's position and line of sight;

[0107] Specifically, real-time rendering technology is applied to adjust the position and appearance of virtual objects in the scene according to the user's real-time position and head posture. This may involve updating the position and orientation of the virtual camera during the rendering process to ensure that the user is viewing the correct virtual content. By using a suitable rendering engine and algorithm, the system can update the virtual scene in real time as the user moves, providing a more immersive experience.

[0108] The operation process of the content management module includes the following steps:

[0109] Collect user data and exhibit data, and extract key features;

[0110] Specifically, a data collection module is set up in the system to collect information such as user location, viewing time, interactive behavior, and related information of exhibits, such as name, description, and label, through sensors in the exhibition space, user devices, or other data sources. Through data preprocessing technology, key features are extracted, such as user interest preferences, viewing frequency, and the theme and artistic style of the exhibits.

[0111] Build a user profile of your audience based on key characteristics;

[0112] Specifically, machine learning algorithms, such as clustering algorithms, are used to analyze and model key features of users to build user portraits. By dividing users into different groups or categories, the system can better understand the interests and characteristics of the audience, providing a basis for personalized recommendations.

[0113] Establish a relationship map between contents based on the classification, labeling and logical association between exhibits;

[0114] Specifically, the exhibits are classified and labeled to establish logical associations between the contents. This may include manually setting labels and classifications, or automatically labeling using natural language processing technology. By establishing a content relationship map, the system can understand the association and semantic relationship between exhibits.

[0115] Use association algorithms to calculate the correlation between different exhibits and form an exhibit association matrix;

[0116] Specifically, association analysis algorithms, such as the Apriori algorithm or the FP-growth algorithm, are used to analyze the selection and order of exhibits by visitors during the exhibition. Through these association rules, an association matrix between exhibits is formed, which reflects the correlation between exhibits and the visitors' exhibition paths.

[0117] Combine user portraits and content association matrix to establish a personalized recommendation model;

[0118] Specifically, a machine learning algorithm, such as a rule-based recommendation algorithm or a content-based recommendation algorithm, is used to combine user portraits and content association matrices to establish a personalized recommendation model. The model can predict the exhibits that users may be interested in and provide them with a personalized recommendation list.

[0119] Use collaborative filtering algorithms to predict exhibits that users are interested in and provide personalized recommendations;

[0120] Specifically, collaborative filtering algorithms, such as user-based collaborative filtering or item-based collaborative filtering, are applied to analyze the similarities between visitors and other visitors and predict the user's interest in unvisited exhibits. By combining user portraits and the prediction results of collaborative filtering algorithms, the system generates a final personalized recommendation list to enhance the visitor's exhibition experience.

[0121] In this embodiment, the operation process of the lighting control unit uses light sensing sensors and digital filtering technology, and the system can collect and process the light data of the exhibition space in real time, ensuring that the lighting effects can quickly and accurately adapt to the changing ambient light conditions. By establishing a scene library and machine learning model, the system can adjust the lighting effects according to different exhibition scenes and user needs to create a unique atmosphere that is more in line with the exhibition theme. A feedback mechanism is set up. By monitoring the user's reactions and feelings, the system can not only adjust the dynamic adjustment algorithm, but also continuously learn and optimize the lighting effects to improve user satisfaction.

[0122] The operation process of the multimedia display module adopts virtual reality and augmented reality technology, so that users can experience more immersive and interactive digital media content in the exhibition space, which enhances the visitor's perception and interactive experience. Using real-time rendering technology, the system can dynamically adjust the position and appearance of virtual objects according to the user's position and line of sight, ensuring that the user is always in the best viewing position, enhancing the visibility and attractiveness of the exhibition content. Interactive elements such as gesture recognition and touch screen control are designed to enable users to interact with digital content more intuitively, improving user participation and experience.

[0123] The operation process of the content management module is to establish a personalized recommendation model through user portraits and content association matrices, provide visitors with exhibit recommendations that match their interests and preferences, and improve the audience's participation and satisfaction. The function of dynamically loading and unloading multimedia content is realized. The system can preload content that may be of interest to visitors in real time according to the location and interests of visitors, ensuring that the exhibition hall can change flexibly and making the exhibition content more attractive. Combining user data and exhibit data, the system establishes a relationship map between content and calculates the correlation between exhibits through association algorithms. This allows administrators to gain in-depth understanding of the relationship between audience behavior and exhibits, providing strong data support for the optimization of exhibitions.

[0124] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
