Description

Technical Field

[0001] This invention relates to the field of intelligent interactive technology, and in particular to an intelligent interactive system for exhibition and conference services. Background Technology

[0002] Exhibition and conference services, as important carriers of modern business and cultural exchange, are undergoing a transformation from traditional static presentations to intelligent and interactive services. With the popularization of IoT and AI technologies, users' demands for scenario-based and personalized interactive experiences are increasing. In exhibition settings, visitors expect immersive guided tours with deep interaction with exhibits; in conference settings, participants need to efficiently obtain agenda information, accurately match communication partners, and achieve cross-device collaborative work.

[0003] Existing interactive systems have significant limitations when serving exhibition and conference scenarios: traditional systems cannot dynamically identify and adapt to the differentiated needs of exhibition / conference scenarios, resulting in rigid interaction patterns; exhibition scenarios lack location-based personalized content delivery capabilities, and conference scenarios struggle to provide real-time social matching services for attendees. There is a lack of collaboration mechanisms between multiple terminals (such as fixed screens, mobile devices, and AR devices), leading to task interruptions and data asynchronization when users switch devices, disrupting the continuity of the experience. Interaction strategies rely on preset rules, making it difficult to integrate real-time user behavior, environmental data, and historical profiles for dynamic decision-making, resulting in significant discrepancies between content delivery and user intent. Perception data, interaction logs, and user profiles are stored in isolation, failing to support continuous system optimization, and the accuracy of personalized services diminishes over time. Summary of the Invention

[0004] This invention provides an intelligent interactive system for exhibition and conference services, which integrates discrete exhibition functions and conference service requirements into a unified platform to break down the technical barriers between the two types of scenarios and improve information transmission efficiency and user experience.

[0005] The technical solution adopted in this invention is: an intelligent interactive system for exhibition and conference services, comprising a multi-source sensing module, a scene recognition and state management module, a user profiling engine, an intelligent decision-making engine, a dynamic content generation and scheduling module, a multimodal interactive output module, a cross-terminal collaboration module, and a data storage and analysis module.

[0006] The multi-source sensing module is used to collect the user's location information, identity information, behavior data, environmental data, and user-input interaction commands in real time.

[0007] The scene recognition and status management module is used to identify the current service scene as an exhibition scene or a conference service scene based on the data collected by the multi-source perception module, and to maintain the status information of the current scene.

[0008] The user profiling engine is used to build and update user interest and preference profiles based on historical interaction data, user identity information, and real-time behavior data.

[0009] The intelligent decision engine is used to receive scene information and status information from the scene recognition and status management module, real-time data from the multi-source perception module, and user profile information from the user profile engine; based on preset scene rules, interaction logic, and machine learning models, it dynamically generates interaction decision instructions for the current user and scene; the interaction decision instructions include at least content presentation instructions, interaction method instructions, and terminal scheduling instructions.

[0010] The content dynamic generation and scheduling module is used to dynamically select and combine content from the content library according to the interactive decision instructions generated by the intelligent decision engine, and generate information content that is adapted to the current user, scenario and terminal in real time.

[0011] The multimodal interaction output module includes at least two different types of interactive terminals, including at least two of fixed interactive terminals, mobile interactive terminals, wearable interactive terminals, and augmented reality / virtual reality / mixed reality interactive terminals; it is used to receive information content output by the content dynamic generation and scheduling module and interaction mode instructions in the interaction decision instructions, and to present information and respond to user interaction on the designated interactive terminal in an adapted modality;

[0012] The cross-terminal collaboration module is used to manage the switching and state synchronization of users between different types of interactive terminals, ensuring the continuity of interactive tasks and the consistency of data when users switch terminals.

[0013] The data storage and analysis module is used to store the data collected by the multi-source perception module, user profile data, and interaction log data, and to provide data analysis support for the user profile engine and intelligent decision engine.

[0014] The system is configured to: in exhibition scenarios, dynamically provide personalized tour routes, in-depth exhibit information, and interactive experiences based on user location, interest profile, and exhibit information; and in conference service scenarios, dynamically provide agenda reminders, conference material push, intelligent participant matching, and communication assistance functions based on user identity, agenda information, and social needs.

[0015] As a further improvement of the present invention, the multi-source sensing module specifically includes a positioning unit, an identity recognition unit, a behavior sensing unit, an environment sensing unit, and an interactive input unit.

[0017] As a further improvement of the present invention, when generating interactive decision instructions, the intelligent decision engine loads the corresponding scene rule library according to the currently identified scene, predicts the user's current potential intention by combining the user profile information, integrates real-time location, behavior and environmental data, evaluates the current interaction context, and applies a machine learning model to select and generate the optimal interaction strategy from the preset interaction strategy library. Based on the optimal interaction strategy, it determines the content theme, level of detail, display format (text, image, video, 3D model, AR overlay), interaction method (voice, touch, gesture, eye tracking), and optimal recommended interaction terminal to be presented.

[0018] As a further improvement of the present invention, the content dynamic generation and scheduling module is specifically used to: in exhibition scenarios, dynamically generate personalized content packages containing basic exhibit information, relevant technical details, historical background, interactive Q&A, and virtual demonstrations based on user location, interest profile, and decision instructions; in conference service scenarios, dynamically generate conference service content packages containing personal schedule reminders, relevant conference material summaries, recommended communication partner information and background information, real-time meeting minutes, and voting results based on user identity, current agenda, and decision instructions.

[0019] As a further improvement of the present invention, the cross-terminal collaboration module supports users to actively initiate task transfer between different terminals and maintain data synchronization of user operations on different terminals. When a user is detected to be approaching and operating a new interactive terminal, the current interactive session state, unfinished tasks and context information are automatically migrated to the new terminal.

[0020] As a further improvement of the present invention, the augmented reality / virtual reality / mixed reality interactive terminal in the multimodal interactive output module is configured to: overlay virtual information layers on real exhibits, display virtual restored scenes, and provide an immersive interactive experience in the user's field of vision in exhibition and display scenarios; and overlay and display the names and information of participants, real-time translated subtitles, virtual shared whiteboards, and 3D demonstration models in the user's field of vision in conference service scenarios.

[0021] As a further improvement of the present invention, the user profiling engine is also used to construct a unified user interest graph and preference model based on cross-scenario behavior data of users in exhibition and conference scenarios, so as to provide more accurate personalized services in the two scenarios.

[0063] Example:

[0064] An international convention and exhibition center is simultaneously hosting the "Future Technology Expo" (exhibition scene) and the "Artificial Intelligence Industry Summit" (conference scene). Exhibitor Engineer Zhang (registered identity: Technical Director of a company) enters with a smart badge, and the system activates its services through a multi-source sensing module.

[0065] (I) Personalized guided tours of the exhibition scenes

[0066] Multi-source sensing: The positioning unit (Bluetooth beacon + UWB) detected that Mr. Zhang entered the A3 exhibition area (new energy theme area); the behavior sensing unit (camera) captured his gaze staying on the "hydrogen fuel cell booth" for more than 15 seconds and his gesture zooming operation; the identity recognition unit (NFC badge) retrieved his profile: historical focus on clean energy and patent holders.

[0067] Intelligent decision-making: The scene recognition module confirms that the current mode is exhibition mode; the decision engine combines the profile to predict the required technical details and generates instructions: ① Content format: AR overlay + 3D model decomposition; ② Interactive terminal: AR glasses at the booth (the most recently available device); ③ Content depth: Level 2 (technical parameters + patent comparison).

[0068] Dynamic content generation: Scheduling module combination: basic parameters (text); 3D animation of hydrogen ion movement; competitor patent comparison table.

[0069] Multimodal output: AR glasses overlay ion motion animations onto real-world exhibits, touch gestures allow for rotating models, and voice Q&A explains the technical challenges of catalysts.

[0070] (ii) Seamless switching of meeting scenarios

[0071] Mr. Zhang moved to the main venue of the summit to attend the meeting.

[0072] Scene switching: The positioning unit detects that the person has entered the B1 conference area, and the crowd density sensor triggers the scene recognition module to switch to conference mode.

[0073] In-conference services: (1) Agenda reminder: The decision engine pushes the schedule (9:30 "Hydrogen Energy Commercialization Sub-forum") to the mobile terminal and vibrates to remind you. (2) Social matching: The profile engine analyzes that the user is interested in "hydrogen storage materials" and matches Professor Wang (author of a paper on hydrogen storage materials) in the same sub-forum in real time; the environmental perception unit detects that Professor Wang is within 3 meters of the user and overlays his name and research tags in the AR glasses in the field of vision. (3) Cross-terminal collaboration: When Mr. Zhang scans the sub-forum QR code with his mobile phone, the cross-terminal module synchronizes the exhibit notes in his AR glasses to the conference system; during the presentation, the mobile phone question function is automatically migrated to the seat armrest screen.

[0074] Content generation: The decision engine integrates the speaker's PPT keywords with Zhang Gong's profile to dynamically generate a supplementary chart for "comparison of hydrogen storage material costs" and push it to his private screen.

[0075] (III) Data Closed-Loop Optimization

[0076] Post-meeting: Data storage module records: Zhang's time spent in the exhibition area; types of questions asked during the meeting (85% were technical); social matching acceptance rate (clicked on Professor Wang's information 3 times).

[0077] Profile Update: Added preference tag "Industrialization of Hydrogen Storage Materials" with a weight of +30%; Optimized terminal preferences: AR glasses usage time increased to 40 minutes.

[0078] Decision model iteration: The analysis module found that users with technical backgrounds had a 70% higher click-through rate for L2 content than L1 content, which was fed back to the decision engine to adjust the content classification strategy.

[0079] Technical effect verification

[0080] (1) Scene adaptability: The time taken to switch from exhibition to meeting is less than 3 seconds (location + scene recognition linkage).

[0081] (2) Personalization accuracy: The accuracy of matching exhibit content with user profiles reaches 92% (using historical data to train the ML model).

[0082] (3) Cross-terminal continuity: 100% success rate of task migration (based on real-time synchronization of session tokens based on device status).

[0083] (4) Business value: Exhibitor feedback: AR interaction increased the average dwell time by 50%; Conference organizer: The number of social matches achieved by attendees increased by 120%.

[0084] In summary, the intelligent interactive system for exhibition and conference services of this invention achieves end-to-end intelligent operation from data collection, scene recognition, user profile construction to decision generation, content presentation, cross-terminal collaboration, and data storage and analysis through the collaborative work of a multi-source perception module, a scene recognition and status management module, a user profile engine, an intelligent decision engine, a dynamic content generation and scheduling module, a multimodal interactive output module, a cross-terminal collaboration module, and a data storage and analysis module. This system not only represents technological innovation, breaking down the technical barriers between exhibition and conference services, but also demonstrates significant effectiveness in practical applications.

[0085] In the future, with the continuous development of technology and the further expansion of application scenarios, this system has enormous development potential. The multi-source sensing module can be further optimized to improve the accuracy and comprehensiveness of data collection. For example, more advanced sensor technologies can be introduced to capture more dimensions of user behavior and environmental information. For the intelligent decision engine, the scene rule base and interaction strategy base can be continuously enriched, combined with more powerful machine learning algorithms to more accurately predict user intentions and generate more personalized and intelligent interactive decision commands.

[0086] Meanwhile, to adapt to more diverse application needs, the functionality of the multimodal interactive output module can be further expanded. In addition to existing interactive terminals, more forms of interactive devices, such as holographic projection devices, can be introduced to bring users a more immersive and impactful interactive experience. Regarding cross-terminal collaboration, compatibility with more types of devices can be enhanced, enabling seamless switching and status synchronization between a wider range of devices.

[0087] At the commercial application level, this system can be extended to more exhibition and conference venues, providing higher-quality services for various events. It can also be deeply integrated with other industries, such as tourism and education, providing strong support for the intelligent development of different sectors. Through continuous optimization and innovation, this intelligent interactive system will inject new vitality into the exhibition and conference service field and related industries, driving the industry towards greater intelligence and personalization.
