Multimodal Turn in Place: A Comparative Analysis of Visual and Auditory Reset UIs in Redirected Walking.

Resetting in redirected walking (RDW) allows users to maintain a continuous, collision-free walking experience in virtual reality (VR), even in a limited physical space. Since frequent resets reduce the user's sense of immersion, extensive research has been conducted to develop resetters that provide optimal reset directions. Various visual reset user interfaces (UIs) have been proposed to help users perform the correct reset direction according to the improved resetter, but their effectiveness has not been sufficiently verified. In addition, expert interviews conducted to identify the problems in the current reset process revealed that users sometimes fail to recognize the visual reset UI in time. Therefore, we propose a novel visual reset UI using Gauge, which is expected to provide users with an effective and high-quality experience. In Study 1, we demonstrate the effectiveness of the Gauge UI by comparing it to existing UIs (Direction, End Point, and Arrow Alignment). Users of various locomotion techniques, including RDW, inevitably need to perform resets, and in this work we propose a novel paradigm: a combined multimodal reset interface.
