- Realistic Impact Perception in Multi-User VR Tennis: Enhancing UX through Hit-Stop and Modification of Others' Movement

Description:
Hit-stop is an expression technique mainly used in fighting games to emphasize an impact response by slowing or stopping a character’s motion. A previous study also found that it can provide a pseudo-impact virtual reality (VR) sensation [Ban and Ujitoko 2021]. However, in VR, observers of a hit-stop often feel uncomfortable when they see the unpredictable movements of the hit-stopping player. In this study, we propose a hit-stop asymmetric presentation method to apply a hit-stop to multi-user VR. We design a hit-stop presentation system in which hit-stops are applied to the user’s own motion, while the observer is presented with the user’s motion converted to a neutral one without hit-stops. Our method could significantly reduced discomfort caused by an opponent’s hit-stopping motion while maintaining a player’s own pseudo-impact sensation for hit-stop [Noguchi et al. 2024]. In our demonstration, we apply this method to a VR tennis environment where two players can play simultaneously. The users can feel that their opponent’s motion is natural, while they perceive a pseudo-impact force sense with their own hit-stops. Therefore, the proposed method should be useful for improving the immersive experience of players in multi-user VR.
