Defining immersion and immersive technologies

This chapter presents findings from a systematic literature review on immersion’s evolving definition amidst recent advancements in immersive technologies. Following PRISMA guidelines, 33 studies (2013-2022) from Scopus were analyzed. The results offer a comprehensive conceptualization of immersion and introduce its constituent elements, termed keys of immersion. The review explores immersion across disciplines, notably in Computer Science and Engineering, focusing on Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) under Extended Reality (XR). It aims to define immersion, examine technology’s role, and identify critical elements for immersive experiences. Central to immersion is technology-mediated illusion, emphasizing sensory stimulation and user engagement (cognitive, emotional, physical). The research identifies six keys: Presence (feeling inside the environment), Cognitive and Emotional Engagement, Sensory Involvement (aligning real and virtual environments), Embodiment (active participation), and Isolation (positive detachment). This review provides a comprehensive overview of immersion’s definition amid technological advances. The keys offer insights for researchers, practitioners, and developers in immersive technologies, shaping understanding of immersive experiences.
