The common multimedia devices in the exhibition hall cover multiple dimensions such as display, interaction, audio-visual, and control, jointly building an immersive and interactive display space. The following is an introduction from three aspects: device type, functional characteristics, and application scenarios:

1、 Display devices: Building visual cores

Large screen display system

LED display/LCD splicing screen: supports high-definition and ultra high definition resolutions, can be spliced into a giant screen, used for playing corporate promotional videos, product demonstration videos, or real-time data. For example, LED screens are commonly used in corporate exhibition halls to showcase brand history, while science museums present large-scale themed content such as space exploration through splicing screens.

Transparent screen/Holographic screen: Display virtual images through transparent or holographic technology to enhance the sense of technology. For example, jewelry showrooms use transparent screens to display the internal structure of jewelry, while car showrooms present 3D models of car models through holographic screens.

Projection equipment: including engineering projectors, ring screens/Ball screen projection, etc., can be projected onto walls, floors, or specially shaped screens to create an immersive visual experience. For example, historical museums use projections to recreate ancient battlefields, while art galleries present starry sky themes through ball screen projections.

Digital sand table

Combining projection and physical models to dynamically display urban planning, geographic information, or project layout. For example, the Urban Planning Museum simulates future urban development through digital sand tables, while the Real Estate Exhibition Hall uses them to showcase the surrounding environment of real estate projects.

2、 Interactive devices: enhance engagement

Touch interaction device

Touch Screen/Touch all-in-one machine: supports viewers to obtain information or participate in games by clicking or sliding. For example, the touch screen in the enterprise exhibition hall can query product parameters, and the education exhibition hall promotes scientific knowledge through interactive games.

Interactive sliding screen/Flying screen interactive table: Content switching or data display can be achieved through sliding or dragging operations. For example, the sliding screen in the technology exhibition hall can display the development history of technology, and the flying screen interactive table is used for data analysis visualization.

Sensory and motion capture devices

Kinect/Leap Motion: Capture audience movements through cameras or sensors to achieve contactless interaction. For example, the game exhibition hall uses motion sensing devices to allow viewers to control game characters through gestures, while the art exhibition hall generates dynamic art works through motion capture.

Ground interactive projection: projecting images onto the ground, and the audience interacts with the content through foot movements. For example, ground projection games in children's exhibition halls can attract children to participate, while commercial exhibition halls use them to create a fun shopping environment.

Virtual Reality（VR/Augmented Reality (AR) devices

VR headset/AR glasses: provide immersive virtual experiences or overlay digital information onto real scenes. For example, VR devices in car showrooms allow visitors to experience the joy of driving, while AR guides in museums present historical backgrounds by scanning exhibits with mobile phones.

3、 Audiovisual equipment: creating an immersive atmosphere

sound system

Surround sound system/Directional sound system: playing background music, commentary, or sound effects, directional sound system can avoid sound interference in other areas. For example, the cinema exhibition hall enhances the viewing experience with surround sound, while the historical exhibition hall creates an atmosphere for specific exhibition areas through directional sound.

Wireless presenter: Convenient for presenters to provide clear explanations to the audience, especially in noisy environments where the effect is significant. For example, during large-scale exhibitions or factory visits, tour guides wear wireless guides to ensure information transmission.

light system

intelligent lighting/Special effects lighting: Creating different atmospheres by adjusting brightness, color temperature, or color. For example, art galleries use lighting to highlight exhibits, while technology galleries use laser lights to create futuristic scenes.

4、 Control devices: Implementing integrated management

Central Control System

As an exhibition hallThe 'brain' centrally manages devices such as lighting, audio, and screens, supporting one click on/off and scene switching. For example, the central control system of the enterprise exhibition hall can unify the control of all equipment and simplify the operation process.

Sensors and Network Devices

infrared sensor/Pressure sensor: detects audience movements or positions, triggering interactive effects. For example, the sensor at the entrance of the exhibition hall can automatically turn on the lights, and the sensor for interactive exhibition items will start the demonstration based on the audience's proximity.

router/Switch: Build a wireless network in the exhibition hall to support audience interaction with the displayed content through mobile devices. For example, Wi Fi in commercial exhibition halls allows visitors to scan codes to participate in online activities.

5、 Auxiliary equipment: Improve display details

Display cabinet/Exhibition rack: used to display physical exhibits, combined with lighting to highlight the display effect. For example, the display cabinets in the jewelry showroom are equipped with LED light strips to enhance the luster of the jewelry.

Guide signage: Provide route guidance or information prompts through electronic screens or signs. For example, the guide signs of large exhibition halls help visitors quickly locate the exhibition area.

Electronic Signature Wall/Photo and souvenir area: Record audience feedback or provide customized souvenir printing services. For example, the electronic signature wall in the enterprise exhibition hall collects visitor information, and the photo area in the technology exhibition hall generates group photos with brand elements.

Suggestions for application scenarios and device selection

Enterprise Exhibition Hall: Key display of brand strength and product technology, recommended for useLED screen, holographic display cabinet, VR experience area, and central control system.

science and technology museum/Museums: Emphasize interactivity and education, suitable for configuring digital sand tables, AR guides, sensory interactive equipment, and special effects lighting.

Commercial exhibition hall: focuses on attracting passenger flow and enhancing experience, and can choose ground interactive projection, transparent screen, intelligent guide robot and wireless guide.

Theme exhibition hall: Customize equipment according to the theme, such as using projection to restore scenes in historical exhibition halls, and creating atmosphere through lighting and sound in art exhibition halls.

The selection of multimedia equipment in the exhibition hall should be based on the exhibition objectives, spatial layout, and budget, and achieve the integration of technology and art through reasonable matching, ultimately creating an unforgettable visiting experience for the audience.
