Driven by the digital wave, multimedia equipment in exhibition halls is undergoing unprecedented changes, transitioning from traditional static displays to intelligent and immersive experiences. These devices not only revolutionize the way information is transmitted, but also reshape the interaction mode between the audience and exhibits through human-computer interaction technology, injecting vitality into various exhibition halls.

1、 Core Device Matrix: Building a Multidimensional Interactive Ecosystem

1. AI digital human explanation system: Virtual image empowers content dissemination

The digital human system creates highly realistic virtual guides through 3D modeling and speech synthesis technology. At the cultural relics exhibition area of Suzhou Museum, digital figures appear in the form of historical figures, telling the stories behind the cultural relics in the first person. Combined with lip sync and emotional expression techniques, the explanations are more immersive. The system supports free switching between Chinese and English, and the content management backend can update explanatory words in real time. A single system can store dozens of theme routes.

Compared to physical robots, digital human systems do not require consideration of mobile navigation and hardware maintenance, making them more suitable for in-depth explanations at fixed points. The practice of the East Branch of Shanghai Library shows that it can complete the inventory and reader navigation of 100000 books per hour, with a recognition accuracy rate of over 98%, and the deployment cost is only one-third of the robot solution.

2. Immersive Space: Reconstructing the Boundary between Virtual and Reality

By using multiple projectors to create a 360 degree surround virtual environment on walls and floors, combined with stereo sound and motion capture technology, real-time interaction between the audience and the virtual scene can be achieved. In the car exhibition hall, visitors can "sit in" concept cars that have not been mass-produced and switch interior color schemes and configuration parameters through gestures; At the science museum, the system can simulate changes in deep-sea pressure, allowing visitors to experience the operation process of deep-sea probes.

The high-end solution also integrates force feedback equipment, such as in the model room display of the real estate exhibition hall, when the audience touches the virtual wall, the gloves will provide feedback on the tactile sensation of different materials. The deployment of a single immersive space requires 4-6 engineering grade projectors, which can increase memory retention by 300% compared to traditional display methods.

3. Holographic projection equipment: a visual revolution of virtual real fusion

Holographic projection technology presents suspended 3D images on transparent media through edge fusion and geometric correction algorithms. The 270 degree display cabinet can showcase the internal structure of the product from three sides, while the 360 degree display cabinet supports viewers to observe around. In the medical equipment exhibition hall, holographic projection can disassemble the internal components of complex equipment, combined with gesture zoom function, allowing the audience to clearly see the operating principle of each part.

2、 Technology Fusion Trend: Creating an Intelligent Central Control System

The intelligent central control system serves as the "nerve center" of the exhibition hall, achieving seamless collaboration between devices through the operating system. When the robot guides the audience into the exhibition area, the system automatically turns on the lights, plays relevant videos, and adjusts the air conditioning to a comfortable temperature; After the audience leaves, the device enters standby mode, reducing energy consumption by 40%.

The system supports multi-level management: small exhibition halls can adopt a lightweight tablet solution; Deploy professional hosts in medium-sized exhibition halls, supporting 50 device access; Large exhibition halls need distributed architecture and edge computing nodes to ensure system stability. The central control system of Huayun Vision has achieved intelligent linkage with 98% of the equipment in the exhibition hall, and the fault response time has been shortened to 30 seconds.

3、 Industry application scenarios: from cultural venues to commercial spaces

1. Cultural and educational field: digital rebirth of historical scenes

Museums reproduce the historical scenes behind cultural relics through digital guides and immersive systems. In the virtual exhibition hall of Dunhuang Academy, visitors can "travel" back to the prosperous Tang Dynasty and watch the process of mural creation; The immersive space of the Nanjing Massacre Memorial Hall reproduces historical events through holographic projection, combined with temperature and odor simulations to enhance emotional resonance.

2. In the field of government services: intelligent guidance of service processes

The intelligent service robots deployed in the government hall can guide the public to complete the business processing procedures. The practice of Puji Hospital in Ningbo City shows that robots achieve VIP automatic recognition through facial recognition, differentiated greetings, and precise navigation, which improves work efficiency by 35%.

4、 Future outlook: Technology iteration drives experience upgrade

With the deep integration of 5G, AI, VR/AR technologies, multimedia equipment in exhibition halls will evolve in three directions:

Personalized experience: dynamically adjust display content and interaction methods through audience portrait analysis;

Green operation: adopting low-power devices and intelligent energy-saving systems to reduce carbon emissions;

Metaverse Fusion: Building a digital twin exhibition hall with virtual and real symbiosis, supporting remote virtual exhibitions.

In this transformation, enterprises that possess the ability to integrate core technologies will dominate the market, and exhibition hall multimedia equipment itself will become a bridge connecting the past and future, reality and virtuality, creating more imaginative perceptual spaces for humanity.
