The Pop-Up Metaverse: A Multi-User, Multi-Tasking Spatial Computing Environment for Collaborative Spatial Problem-Solving.

We introduce the Pop-Up Metaverse, an innovative web-based system seamlessly blending spatial computing with 3D visualization to catalyze collaborative problem-solving in the Industrial Metaverse. The workflow commences with a local user swiftly scanning the environment using a LiDAR-equipped iPhone/iPad, generating a baseline mesh model. Elevating visual fidelity, the system employs the state-of-the-art 3D reconstruction technique, Gaussian-splatting, for captivating photorealistic effects. This enriched 3D canvas becomes a hub for multi-user collaboration, emphasizing the Pop-Up nature facilitated by web technology—no installations required. Key features encompass Remote Assistance, enabling real-time expert guidance within the 3D scene; Human Motion Recorder, scrutinizing movements and postures in recorded human activity; and Spatial Analytics, meticulously tracking environmental changes over time. Ensuring accessibility, remote participation mandates only a web browser, significantly reducing entry barriers to the metaverse experience. The Pop-Up Metaverse empowers a workflow tailored for solving spatial problems by seamlessly uniting the physical and digital realms.
