Shared Presence via XR Communication and Interaction Within a Dynamically Updated Digital Twin of a Smart Space: Conceptual Framework and Research Challenges

Year: 2025

Type: article

Abstract: The integration of emerging eXtended Reality (XR) technologies, digital twins (DTs), smart environments, and advanced mobile and wireless networks is set to enable novel forms of immersive interaction and communication. This paper proposes a high-level conceptual framework for shared presence via XR-based communication and interaction within a virtual reality (VR) representation of the digital twin of a smart space. The digital twin is continuously updated and synchronized—both spatially and temporally—with a physical smart space equipped with sensors and actuators. This architecture enables interactive experiences and fosters a sense of co-presence between a local user in the smart physical environment utilizing augmented reality (AR) and a remote VR user engaging through the digital counterpart. We present our lab deployment architecture used as a basis for ongoing experimental work related to testing and integrating functionalities defined in the conceptual framework. Finally, key technology requirements and research challenges are outlined, aiming to provide a foundation for future research efforts in immersive, interconnected XR systems.
