The design of a 360 digital virtual exhibition hall involves creating an immersive, interactive, and visually engaging environment using virtual reality (VR) technology. Key aspects include: 1) spatial design to create a sense of presence; 2) 3D modeling of exhibits and the exhibition space; 3) incorporating interactive elements such as touchscreens, gestures, and voice commands; 4) ensuring compatibility across various VR devices; 5) and effective storytelling through multimedia content.
