The journey of OSCAR4US
This project aims to promote seamless interoperability and universality akin to the Web, where anyone can discover, publish and access content associated with physical world features of any size, anywhere.
The mission of this project is to develop components of the OSCP further to serve as the basis for city-scale location-based AR by focusing on three core work streams:
(1) An Open Visual Positioning Service (OpenVPS) including existing localisation algorithms and new user-friendly mapping tools.
(2) Continuous context-aware search for services and content (also termed “spatial discovery”), and
(3) A shared, machine-readable, standardised description of the physical environment, which we call a “Reality Modeling Language.”
Our representative use cases involving mobile pedestrians, vehicles, and numerous obstacles offer the opportunity to build and test tools for search and discovery services, virtual content authoring, and community sharing. We also provide developers with tutorials on using the OSCP in third-party applications.

During the XRExpo conference, which took place in Stuttgart, Germany, on May 8th, project team members of OSCAR4US were hosting a workshop and live demo session with the title “Enhancing XR experiences with interoperable Visual Positioning Systems". We utilised the prominent facilities to map and place content the day before the event, ensuring we could include a live demo experience during this interactive workshop session hosted by Open AR Cloud Europe, Augmented City, which explored the world of Visual Positioning Systems (VPS) and POI services.

The Open AR Cloud Europe gUG together with the US entity Open AR Cloud Association joined forces and submitted a tutorial which was recently accepted. The title of the 4-hour tutorial is Building interoperable location-based augmented reality with the Open AR Cloud. Sign up and join the tutorial session during this Ubicomp/ISWC 2025 October 14-16, 2025 in Espoo, Finland and learn more about the NGI Search project and its outcome.
