Integrating Extended Reality, 3D Modelling, and Natural Interaction in Cultural Heritage Fruition Systems

This paper explores technical innovations in Extended Reality (XR) applied to cultural heritage through three distinct yet converging projects: 'Trevignano Experience', 'ArcheoVerso', and the locomotion interface. By integrating high-precision 3D scanning, photorealistic modeling, and real-time interaction systems, these initiatives establish a methodology for immersive storytelling and digital access to heritage. Particular attention is given to user-centered design, hybrid locomotion techniques, and their impact in shaping persistent digital environments. The work is grounded in empirical testing, comparative usability assessments, and structured pipelines for data acquisition and experience deployment.
