The Potential Disconnect between Time Perception and Immersion: Effects of Music on VR Player Experience

How much music contributes to player experience (PX) in virtual reality (VR) games remains unclear in the games user research literature. A core factor of PX in VR games that has not been studied before (in relation to audio or otherwise) is time perception. Thus, we provide the first empirical exploration of how music affects time perception in a VR game. In a user study (N=64), we investigated the effects of music on PX and time perception (operationalized as retrospective time estimation). Participants retrospectively perceived time to pass significantly quicker in the VR game when music was present, but reported no difference in PX components, including immersion. This contributes to ongoing discourse on the surprising lack of music effects in VR games. Moreover, our results highlight the need to re-conceptualize our understanding of the relationship between time perception and immersion in games.
