A Matter of Perspective: Designing Immersive Character Transitions for Virtual Reality Games

Abstract

Virtual reality (VR) games intensify storytelling experiences by letting players take the role of a character. However, in contrast to films, novels, or games, VR experiences often remain centered around one single character without using the potential of complex multiprotagonist plots. Our work engages in this critical topic by investigating the design of immersive and natural transitions between different characters. First, we conducted a scoping review to identify existing multiprotagonist VR games (N=18) and grouped their used transition techniques into four categories. Based on these findings and prior research, we designed two transition techniques (Static Map vs. Rebodying) and conducted a between-participants (N=36) study to explore their effect on user experience. Our results show that Rebodying outperforms Static Map regarding the perceived realism, acceptance, and spatial understanding of the character transitions. Both conditions do not differ significantly in terms of cybersickness. Finally, we provide future directions for developing, improving, and exploring of multiprotagonist transition techniques in VR games.
