“…In a similar fashion, galvanic vestibular stimulation can also be used to enhance vection if it is reasonably compatible with the available visual motion stimulation. For example, applying galvanic vestibular stimulation during visual motion has been found to reduce vection onset latencies and increase vection strength [ 27 , 48 ]. Applying bone conducted vibration at the mastoid processes (known to affect the vestibular system) also appears to have a similar effect on vection onset latency.…”

“…As noted above, physical observer motions are often not possible in VR or during vehicle simulation. While galvanic and other types of vestibular stimulation have the potential to reduce vection onset latencies in future applications [ 48 – 50 ], at the moment they are rather coarse, invasive and uncomfortable (as discussed by [ 51 ]). Visual display manipulation may therefore present a more practical and affordable solution to the problem of reducing vection onset latencies in the near future.…”

Typically it takes up to 10 seconds or more to induce a visual illusion of self-motion (“vection”). However, for this vection to be most useful in virtual reality and vehicle simulation, it needs to be induced quickly, if not immediately. This study examined whether vection onset latency could be reduced towards zero using visual display manipulations alone. In the main experiments, visual self-motion simulations were presented to observers via either a large external display or a head-mounted display (HMD). Priming observers with visually simulated viewpoint oscillation for just ten seconds before the main self-motion display was found to markedly reduce vection onset latencies (and also increase ratings of vection strength) in both experiments. As in earlier studies, incorporating this simulated viewpoint oscillation into the self-motion displays themselves was also found to improve vection. Average onset latencies were reduced from 8-9s in the no oscillating control condition to as little as 4.6 s (for external displays) or 1.7 s (for HMDs) in the combined oscillation condition (when both the visual prime and the main self-motion display were oscillating). As these display manipulations did not appear to increase the likelihood or severity of motion sickness in the current study, they could possibly be used to enhance computer generated simulation experiences and training in the future, at no additional cost.

“…Self-motion illusions can, however, also be induced by other modalities including auditory (see reviews by Väljamäe, 2009), tactile (Dichgans & Brandt, 1978), or biomechanical cues (Bles, 1981;Brandt et al, 1977) or from direct galvanic stimulation of the vestibular system (Cress et al, 1997;Lepecq et al, 2006). In the following, I will review different factors that have been shown to facilitate vection, and how they might be utilized in VR and other immersive situations.…”

“…For example, galvanic vestibular stimulation can both directly induce self-tilt and affect visually simulated self-motions (Cress et al, 1997;Lepecq et al, 2006). Adding subtle vibrations to the observers' seat and footrest has been shown to enhance visual vection Schulte-Pelkum, 2007).…”

“…Research by Weech and Troje (2017) has shown that visual vection latency can be reduced when GVS signals that do not induce selfmotion in any particular direction are administered to participants. Cress et al (1997) reported significantly higher motion fidelity ratings by participants when galvanic vestibular stimulation that induced roll axis tilt was combined with a visual display indicating tilt in the same direction.…”

Visual-Vestibular Sensory Integration During Congruent and Incongruent Self-Motion Percepts

This thesis examined the contribution of vestibular cues to self-motion perception and their integration with visual self-motion cues. The thesis is divided into five sections. In Section 1, a review of the illusory self-motion perception (i.e., 'vection') literature situates studies undertaken in this thesis. Topics reviewed include vection research, vestibular anatomy and physiology, visual-vestibular sensory integration, visual-vestibular neurophysiology and measurement methods to index vection. In Section 2, two experiments were reported. In E1, a virtual drum was displayed on a virtual reality headset. In E2, a novel measurement method consisting of a circular knob that participants rotated when experiencing vection was used to provide a direct measure of vection speed, direction, and duration. Results showed that vection strength and speed increased as visual stimuli moved faster. In Section 3, two experiments were reported in which circular vection was induced using vestibular air caloric stimulation. Participants had their eyes closed in E3 while receiving caloric vestibular stimulation. In E4 participants received caloric vestibular stimulation while viewing a stationary image in a VR headset. Participants perceived vection in the clockwise direction when cold air was applied to the left ear, and perceived counterclockwise vection when caloric stimulation was in the right ear. Vection speed and duration measures were significantly smaller when participants viewed a stationary display (E4) than when their eyes were closed (E3). In Section 4, the goal was to determine if the visual or vestibular system prevailed in determining direction of self-motion perception during cue conflict. Participants observed an optic flow pattern that induced circular vection while receiving caloric vestibular stimulation also inducing vection. Visual and vestibular stimuli induced vection of approximately equal speeds in two conditions. In the 'congruent motion' condition, visual and vestibular stimuli signaled vection in the same direction. In the 'incongruent motion' condition, visual and vestibular stimuli signaled vection in opposite directions. Results showed that in the incongruent condition, participants experienced vection in the direction signaled by the visual stimulus and vestibular stimulus equal amounts of times. In Section 5, a general discussion on these findings as they relate to optimal cue integration hypothesis is provided.
