Where are you? Influence of Redirected Walking on Audio-Visual Position Estimation of Co-Located Users

摘要

Two-user redirected walking (RDW) promises new possibilities for collaborative experiences in virtual reality (VR), but it also introduces challenges like the spatial de-synchronization emerging when one or more users are redirected in different ways. We analyzed the ability to estimate a co-located user’s position, and assessed the feeling of representation consistency in an interactive game. Results show that a user’s estimation of the other’s position improves when their partner’s virtual and physical position get closer together. Furthermore, larger redirection gains lead to a lower feeling of consistency, which also applies if only one person is redirected.
