XR Masters at UbiComp ISWC 2025: Bringing Open AR Cloud to the World Stage
On October 12, 2025, Our CEO Ali C. Hantal had the honor of presenting at UbiComp ISWC 2025 — one of the most prestigious international conferences in ubiquitous and wearable computing — held at Aalto University in Espoo, Finland. Alongside a world-class group of spatial computing researchers and practitioners, Mr. Hantal co-delivered a half-day tutorial titled “Building Interoperable Location-Based Augmented Reality with the Open AR Cloud,” organized by the Open AR Cloud Association.
This was a significant moment for XR Masters and for the broader mission we share with the Open AR Cloud community: advancing an open, interoperable spatial web that any developer, device, or platform can participate in.
About the Tutorial
The three-and-a-half-hour tutorial — held from 14:30 to 18:00 EEST in Room U7 at the Aalto University Undergraduate Centre — brought together developers, researchers, and practitioners to explore the full technology stack required for an interoperable spatial web. The session covered how to publish, discover, and consume AR content anchored to a digital twin of real-world locations, and how this intersects with technologies such as 5G, edge computing, and smart sensors.
The tutorial was organized by the Open AR Cloud Association, and featured presenters from Nokia Bell Labs, AT&T Labs, the Institute for Energy Technology (Norway), the University of Mittweida, and XR Masters.
My Sessions: Client-Side Development and Live AR Demo
I participated in two sessions during the tutorial.
Client-Side Development (co-presented with Mikel Salazar, IFE). This 40-minute session introduced participants to the spARcl open-source web client and walked through OSCP protocol integration — covering GeoPose, spatial content discovery, and spatial search. We demonstrated how AR content can be rendered and localized using OSCP standards, and engaged the audience with live coding. This session brought together precisely the kinds of open standards — OGC GeoPose and OSCP — that sit at the foundation of what we are building with MyGeoVerse. Seeing developers work hands-on with these tools in real time was a powerful reminder of why building on open standards matters.
Live AR Demo (co-presented with Gabor Soros, Nokia Bell Labs). To close the tutorial, the audience stepped outside onto the Aalto Campus for a live demonstration featuring web and mobile spatial browsers. Seeing attendees experience real-world AR content anchored to physical locations — delivered through open, interoperable infrastructure — was one of the highlights of the entire event. It made the abstract technology tangible in a way that no slide deck can match.
The Bigger Picture: Why UbiComp Matters for Spatial AI
UbiComp ISWC draws researchers and engineers working at the frontier of how computing integrates with the physical world — exactly the intersection where XR Masters operates. The tutorial reinforced several convictions that guide our work:
Interoperability is not optional. The AR and spatial computing ecosystem is fragmented across devices, operating systems, and positioning systems. Open standards like OGC GeoPose and the OSCP protocol are the connective tissue that makes a truly open spatial web possible. Without them, every deployment becomes a proprietary island.
The developer community is ready. The engagement during the live coding and demo sessions demonstrated that developers want to build on open infrastructure. The tools, libraries, and standards exist. What the ecosystem needs now is platforms that make it easy to adopt them at scale — which is exactly the role MyGeoVerse is designed to play.
Visual positioning is the linchpin. The Visual Positioning segment of the tutorial — showcasing interoperability between Immersal, Augmented City, and Nokia’s OpenVPS — made clear that 10–20 cm spatial accuracy is achievable today, and that the OARC GeoPose Protocol is the right abstraction layer to unify these systems. This is the same accuracy standard that MyGeoVerse is built to deliver.
XR Masters and Open AR Cloud
As Co-President of the Open AR Cloud Association and Adoption Officer for the GeoPose Standards Working Group at the Open Geospatial Consortium (OGC), my involvement in events like UbiComp goes beyond representing XR Masters. It reflects a broader commitment to building the open ecosystem that a spatial AI future requires.
MyGeoVerse is purpose-built to publish spatial content in compliance with OGC and OSCP standards, enabling AR cloud-powered and conversational AI avatar experiences across tourism, education, retail, and smart city deployments. Everything we demonstrated at UbiComp is directly connected to the platform we are bringing to market — across Android XR, Meta Ray-Ban, and other major spatial interfaces.
Thank You to Our Co-Presenters
A genuine thank you to the organizers and fellow presenters who made this tutorial exceptional: Gabor Soros (Nokia Bell Labs), James Jackson (AT&T Labs / Open AR Cloud), Mikel Salazar (IFE / Open AR Cloud), Jan-Erik Vinje (Open AR Cloud), Alina Kadlubsky (University of Mittweida), Mikko Karvonen (Immersal), and Katherina Ufnarovskaia (Augmented City). The depth of expertise and collaboration in that room was a privilege to be part of.
