A research prototype for the 360 Gallery in Hong Kong, developed in collaboration with the Extended Reality Lab at City University of Hong Kong. Conceived as a shared spatial system where cylindrical stereoscopic projection, HoloLens 2 AR, and mobile interfaces could be tested within a single immersive volume. An AR authoring workflow was integrated into the existing 360 Gallery infrastructure, aligning iOS interfaces, head-mounted devices, and the projected scene.

The pipeline involved multi-computer synchronisation, OSC-based real-time communication, OptiTrack motion capture, and Unreal Engine 4 tools for stereoscopic rendering and distributed control. Rather than a finished product, Holodeck functioned as a working framework — a study in coordination examining how different viewpoints, tracking systems, and display logics could sustain a continuous relationship between bodies, screens, and virtual objects without fragmenting the spatial experience.
