Spatial Affairs, an international XR residency exploring immersive performance. The work included developing the multiplayer platform to enable real-time, interactive XR experiences with location tracking and multi-user mechanics. Guiding and supporting artists through prototyping, supporting the Mesh Festival presentations, managed installation setup, calibrated hardware, and assisted audiences. Additional tasks involved constructing a DIY charging station and creating an introductory scene for visitors to get familiar with XR. This experience strengthened expertise in multiplayer XR design, real-time interaction, and live deployment, while witnessing the seamless fusion of technology and artistic vision.
