| Abstract |
As urban facility management becomes increasingly complex, there is a growing need for an effective remote collaboration environment. However, existing studies on Mixed Reality (MR) have been limited to specific tasks or single-user scenarios. This study, therefore, aims to propose and validate an effective system architecture for an MR-based digital workplace that supports real-time collaboration among multiple remote users for managing largescale, heterogeneous urban spatial data. To address this, we designed a client-server architecture composed of a Digital Workplace Server (DWS) for centralized data processing and synchronization, and an MR Operation System (MOS) for user-side visualization and interaction. Performance validation based on a virtual scenario confirmed that the proposed system could render 1.94 GB of large-scale 3D data and synchronize interactions between users, with both tasks being completed in under 3 seconds on average. These results demonstrate that the proposed architecture is a viable solution for building a collaborative MR environment for city-scale facility management. The primary contribution of this research lies in presenting and empirically validating a system architecture that addresses the limitations of previous studies. |
