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.

Strategic Orientation

• Vision Statement:

To implement cross-partner research and development on innovative technologies and applications of Extended Reality (XR) for social and cultural domains, driving next-generation immersive interaction ecosystems .

• Core Mission / Objectives:
  • Integrate XR technologies into societal and cultural applications.
  • Create scalable, real-time, multi-user XR systems through interdisciplinary research.
  • Combine advances in visual, auditory, and interactive modalities for holistic user experiences.
  • Establish a bridge between academic research and industrial application.
• Strategic Pillars / Focus Areas:
  1. Basic Technologies: Visual streaming, 360° sound, AI-driven meshing and rendering, motion capturing, and photogrammetry.
  2. Infrastructure Technologies: Data transmission, processing, and distributed system performance.
  3. Application Domains: Education, mobility, cultural heritage, and retail environments.

• Expected Outcomes / KPIs:
  • Demonstration of scalable multi-user XR platforms.
  • Integration of XR systems with AI and sensor data.
  • Prototypes for real-time immersive collaboration tools.

Alignment with Virtual Worlds

Relevance to Virtual Worlds Domains:

The XR-INTERACTION network offers a complete XR technology chain — from acquisition (sensing and recording) to distribution and interaction — directly matching OPENVERSE’s goal of federating European immersive ecosystems.

Key Alignment Points:

• Technological Depth: Provides foundational research for real-time, distributed XR experiences.
• Interoperability: Encourages open, modular integration of technologies across domains.
• Human-Centric Design: Focus on social and cultural use cases complements OPENVERSE’s emphasis on societal relevance.
