== XR-INTERACTION Roadmap (2025) ==
The ''XR-INTERACTION Roadmap (2025)'' sets out a coherent vision for '''technological, infrastructural, and application-driven research''' in Extended Reality. It aims to build integrated implementation chains—from sensing and recording through processing and interaction—to support real-time, multi-user XR applications.

For '''OPENVERSE''', XR-INTERACTION represents a '''technological cornerstone''': it provides foundational R&D for immersive systems that can be federated across Europe’s XR ecosystem. Its focus on social, cultural, and educational applications offers a natural entry point for OPENVERSE’s orchestration and standardisation efforts in the virtual worlds domain.

=== Basic Identification ===
