MN VR and HCI Apr 2026: Mastering Space & Time
SpacetimeDB is a new approach to scalable networking for both VR and general game projects. Bonus quick overview of the XREAL One Pro glasses SDK.
Mastering Space & Time – David Mann
Using Dungeonpunk Online as the case study, David Mann will walk through the multiplayer architecture he has been building, with a focus on how SpacetimeDB, Unity, modern authentication flows, and live simulation fit together in practice. As part of that work, he built dungeonpunk.dev, a custom authorization portal created out of necessity to handle identity, token exchange, and secure game connectivity. The talk focuses on the design decisions, integration challenges, and tradeoffs involved in keeping the overall system simple, maintainable, and realistic to operate as a team of one.
The presentation will also include a short addendum on the XREAL One Pro glasses, covering what David found while attempting to integrate them into a real game project. It will examine the current state of the tooling, the developer ecosystem, and the practical realities.
David Mann is an independent developer and craftsman of fine technology with experience across games, web development, DevOps, VR, and real-time multiplayer systems. He uses that broad skill set to build custom systems spanning product, infrastructure, and operations.
