“…Various properties of self-motion such as speed, distance, and heading direction can be detected from visual information (e.g., Lappe et al, 1999 ; Sun et al, 2004 ). The visual self-motion information can alter other visual perception such as object motion (e.g., Probst et al, 1984 ), temporal order of visual events (Teramoto et al, 2004 ), and depth (Watanabe et al, 2004 ). In the auditory localization literature, previous studies reported that rotation of a visual environment around the vertical axis caused displacement of a sound source in the direction of visual motion (i.e., in the opposite direction of induced self-motion) (Thurlow and Kerr, 1970 ; Cullen et al, 1992 ; Otake et al, 2006 ; see also Väljamäe, 2009 for a review).…”

Perception of self-motion is based on the integration of multiple sensory inputs, in particular from the vestibular and visual systems. Our previous study demonstrated that vestibular linear acceleration information distorted auditory space perception (Teramoto et al., 2012). However, it is unclear whether this phenomenon is contingent on vestibular signals or whether it can be caused by inputs from other sensory modalities involved in self-motion perception. Here, we investigated whether visual linear self-motion information can also alter auditory space perception. Large-field visual motion was presented to induce self-motion perception with constant accelerations (Experiment 1) and a constant velocity (Experiment 2) either in a forward or backward direction. During participants' experience of self-motion, a short noise burst was delivered from one of the loudspeakers aligned parallel to the motion direction along a wall to the left of the listener. Participants indicated from which direction the sound was presented, forward or backward, relative to their coronal (i.e., frontal) plane. Results showed that the sound position aligned with the subjective coronal plane (SCP) was significantly displaced in the direction of self-motion, especially in the backward self-motion condition as compared with a no motion condition. These results suggest that self-motion information, irrespective of its origin, is crucial for auditory space perception.

“…This was to investigate whether changes in the perception of passable width during self-motion simulation were caused by changes in the apparent depth of the aperture by the background motion, and not by the self-motion mechanisms (cf. Watanabe et al, 2004). There were two background sessions: moving and static background sessions.…”

Previous studies have shown that space perception around the body is altered by self-motion, and that several self-motion cues from different modalities, including vision, proprioception, the vestibular system, and the motor system (motor commands) contribute to it. However, studies on how online self-motion information affects the perception of a passable width of a narrow aperture is largely overlooked by existing literature. Therefore, this study investigated this issue during virtual bike riding. Participants observed a narrow doorway aperture with varied widths in a virtual environment through a head-mounted display while riding a stationary bike. Visual self-motion information was presented by optical flow, while motor commands and proprioceptive feedback (non-visual information) was provided by having participants pedal the bike. The participants were then required to judge whether the presented aperture was passable. Experiment 1, where both visual and non-visual cues were provided, confirmed that the perceived passable width significantly increased with increasing self-motion speed, as previously shown during walking. Experiment 2, where self-motion cues were manipulated, showed that expansion of the perceived passable width was mainly induced by visual self-motion information. These results suggest that online self-motion information can affect passable width perception during bike riding and that visual self-motion information plays a significant role in this perception.
