== XR-INTERACTION Roadmap (2025) ==
The ''[https://xr-interaction.com/roadmap/ 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''', [https://xr-interaction.com/ 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 ===
'''Initiative / Partnership Name:''' [https://xr-interaction.com/ XR-INTERACTION] – Research Alliance for Extended Reality

'''Full SRIDA Title & Version:''' ''[https://xr-interaction.com/roadmap/ XR-INTERACTION Roadmap (2025)]''

=== 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:'''
# '''Basic Technologies:''' Visual streaming, 360° sound, AI-driven meshing and rendering, motion capturing, and photogrammetry.
# '''Infrastructure Technologies:''' Data transmission, processing, and distributed system performance.
# '''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:'''
