Interplay of User Behavior, Communication, and Computing in Immersive Reality 6G Applications

Abstract

Emerging extended reality (XR) services and applications that submerge users into a virtual universe pave the way toward ubiquitous contextualized experiences. Immersive interactions on-the-go not only bring new use cases but also distract users from the real world and modify their behavior and motion, which may, in turn, affect the operation of communication networks. This article explores the effects of XR user motion from the communication and computing perspectives. To this end, we offer a review of mobility patterns in XR and a detailed simulation study regarding the impact of interactiondependent gait patterns on delay and resource utilization. The results confirm the uniqueness of XR applications in terms of user behavior patterns, which calls for novel applicationcentric algorithms, protocols, and mechanisms to facilitate highperformance connectivity under demanding XR requirements.

Toward immersive communications in 6G

“…Several recent review and survey articles can be found in the literature, among which some present state of the art in immersive communications, while others envision the next steps. Most of these articles focus on a specific aspect, such as supporting 360 • /holographic video streaming (Yaqoob et al, 2020;Huang et al, 2022), evaluating the immersive experience of users (Gao et al, 2022a), analyzing the effects of user motions on network performance in XR (Chukhno et al, 2022), enabling the use case of Metaverse (Tang et al, 2022;Wang et al, 2022b;Xu et al, 2022), or facilitating distributed implementation of VR (Morín et al, 2022). Different from the above works, we present a comprehensive survey of immersive communications in this article.…”
