“…The rotational redirection detection threshold range of the visual attractor with the auditory stimulus is similar to that of the visual attractor (Nilsson et al 2016). Even with visibility limited by dense fog, visual information still predominantly affects redirection performance, whereas auditory stimulus does not influence it (Junker et al 2021). Additionally, when a scent and olfactory display coexisted under a directional mismatch, users could not distinguish the actual scent direction owing to visual information interference (Tsai et al 2021).…”

“…Therefore, we hypothesized that the use of nonvisual attractors increases the levels of manipulation perception and VR sickness, as these attractors allow for wider and longer visual observation of the manipulated virtual scenes. In addition, our use of a rotation gain above the threshold level reported in previous studies on redirected walking using audio stimulation (Junker et al 2021;Nilsson et al 2016) may also contribute to VR sickness and manipulation perception. However, our V, A, and O stimuli were matched to the task context and snack object characteristics that the user seeks.…”

“…Olfactory attractor is perfumed from an all-in-one system, where the target is behind the user. (b2), (c2), and (d2) the user leaves the collision-detection area as in the case of visual attractors (Junker et al 2021;Serafin et al 2013).…”

In virtual reality, redirected walking (RDW) enables users to stay within the tracking area while feeling that they are traveling in a virtual space that is larger than the physical space. RDW uses a visual attractor to the user’s sight and scene manipulation for intermittent reorientation. However, repeated usage can hinder the virtual world immersion and weaken the reorientation performance. In this study, we propose using sounds and smells as alternative stimuli to draw the user’s attention implicitly and sustain the attractor’s performance for intermittent reorientation. To achieve this, we integrated visual, auditory, and olfactory attractors into an all-in-one stimulation system. Experiments revealed that the auditory attractor caused the fastest reorientation, the olfactory attractor induced the widest angular difference, and the attractor with the combined auditory and olfactory stimuli induced the largest angular speed, keeping users from noticing the manipulation. The findings demonstrate the potential of nonvisual attractors to reorient users in situations requiring intermittent reorientation.

“…proach is to provide the user with spatialized auditory feedback from virtual object(s) that is consistent with visual manipulation [4]- [6]. This approach is based on a phenomenon in which the consistency of the auditory and visual cues makes it more likely to perceive the rotation of the entire VE as self-motion [7].…”

“…This approach is based on a phenomenon in which the consistency of the auditory and visual cues makes it more likely to perceive the rotation of the entire VE as self-motion [7]. However, the results of those studies show a limited effect of auditory cues; while one study showed an expanded range of DTs [4], two others showed no differences in DTs between usage with and without auditory feedback [5], [6]. Nilsson et al [5] suggested that the reason for such a limited effect is that vision is generally superior to audition when estimating spatial locations of objects [8].…”

We examine the effect of auditory cues occurring in reality on redirection. Specifically, we set two hypotheses: the auditory cues emanating from fixed positions in reality (Fixed sound, FS) increase the noticeability of redirection, while the auditory cues whose positions are manipulated consistently with the visual manipulation (Redirected sound, RDS) decrease the noticeability of redirection. To verify these hypotheses, we implemented an experimental environment that virtually reproduced FS and RDS conditions using binaural recording, and then we conducted a user study (N = 18) to investigate the detection thresholds (DTs) for rotational manipulation and the sound localization accuracy of the auditory cues under FS and RDS, as well as the baseline condition without auditory cues (No sound, NS). The results show, against the hypotheses, FS gave a wider range of DTs than NS, while RDS gave a similar range of DTs to NS. Combining these results with those of sound localization accuracy reveals that, rather than the auditory cues affecting the participants' spatial perception in VR, the visual manipulation made their sound localization less accurate, which would be a reason for the increased range of DTs under FS. Furthermore, we conducted a follow-up user study (N = 11) to measure the sound localization accuracy of FS where the auditory cues were actually placed in a real setting, and we found that the accuracy tended to be similar to that of virtually reproduced FS, suggesting the validity of the auditory cues used in this study. Given these findings, we also discuss potential applications.
