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.
  • Growth of the partner ecosystem (academic–industrial).

Policy Alignment:

Technological and Thematic Priorities

A. Basic Technologies (as shown in diagram on page 2)

  • Sound: 360° spatial sound and binaural systems.
  • Visual Streaming: 360° stereoscopic and volumetric video.
  • Algorithm / AI: Meshing, shading, clipping, and culling.
  • Motion Capturing: Markerless and inertial-based tracking.
  • Objects and Rooms: Modelling, configuration, and photogrammetry .

B. Infrastructure Technologies

  • Transmission and Processing: High-performance pipelines for data handling.
  • Scalability: Distributed systems supporting multi-user environments.
  • Performance Optimisation: Synchronisation of visual and auditory streams with low latency.

C. Applications

  • Social Interaction and Collaboration: Real-time co-presence and multi-user engagement.
  • Cultural Heritage and Education: Immersive reconstructions, remote learning environments.
  • Mobility and Navigation: XR-based urban and transport simulations.
  • Retail and Consumer Spaces: Experiential commerce and mixed-reality product interaction.

Cross-cutting Topics:

  • Real-time rendering and data transmission.
  • AI integration across the XR pipeline.
  • Ethical and sustainable design.
  • Accessibility and inclusion in immersive experiences.

Synergies:

Governance & Ecosystem

Leading Organisations / Associations: Chemnitz University of Technology (coordinator) with multiple European R&D and industrial partners.

Stakeholder Groups: Academia, creative industries, XR technology providers, AI developers, cultural institutions, and SMEs.

Engagement Mechanisms:

  • Open research and development network.
  • Collaborative projects among industry and academic labs.
  • Joint dissemination through conferences and demonstrators.
  • Update Frequency: Continuous roadmap update tied to partner project cycles (annual review).
  • Contact / Participation Info: Available via coordinator at https://xr-interaction.com/coordinator.

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.
