Abstract
UrbanSight is a collaborative mixed-reality platform that connects a live digital twin with physical architectural models through HoloLens 2. Multiple users share a synchronized holographic workspace, interacting with real-time BIM data, geospatial overlays, and 3D urban models co-located in the same physical space.
The system was awarded the Young CAADRIA Award 2024, recognizing its contribution to integrating digital twin technology with human-centered mixed-reality interfaces for architectural design review.
Key Contributions
- Multi-user shared holographic space using Azure Spatial Anchors for world-locked alignment across HoloLens 2 devices.
- Real-time BIM integration: IFC data streamed and rendered as interactive 3D holograms at 1:1 and reduced scales.
- Gesture-based UI for layer toggling, cross-section cutting, and annotation directly in AR space.
- Received the Young CAADRIA Award at CAADRIA 2024, Singapore.
