Abstract:Sounds are thought to contribute to the perceptions of self-motion, often via higher-level, cognitive mechanisms. This study examined whether illusory self-motion (i.e. vection) could be induced by auditory metaphorical motion stimulation (without providing any spatialized or low-level sensory information consistent with self-motion). Five different types of auditory stimuli were presented in mono to our 20 blindfolded, stationary participants (via a loud speaker array): (1) an ascending Shepard-Risset glissan… Show more
“…Although the authors found a positive effect of multisensory stimulation on the subjective measures, postural steadiness was not affected by any form of stimulation. Conversely, Mursic et al (2017) investigated whether vection could be elicited through auditory stimulation that simulated metaphorical motion. Participants performed a Romberg test whilst standing on a pressure plate that recorded their CoP after which they viewed a series of visual stimuli aimed to elicit vection.…”

Vection is classically defined as the illusory perception of self-motion induced via visual stimuli. The utility of vection research lies in its potential to enhance simulation fidelity as measured through presence and reduce the probability that motion sickness symptoms occur through the identification of differences and similarities in physiological responses to vection and motion sickness. Recent studies have shown a multimodal interaction of various sensory systems in facilitating vection. Moreover, the utility of co-stimulating some of these sensory systems along with the presentation of visual stimuli have been reviewed. However, a review on the tactile mediation of vection appears to be missing from literature. The purpose of this review is to evaluate the current methodologies, and utility of, tactile stimulation in vection research. We searched for articles through EBSCOHost, Scopus and Web of Science. Only studies were included wherein an experiment on the effect of tactile stimulation on human self-motion perception was detailed. Twenty-three studies were obtained and distilled in tabular form. The studies reviewed presented a strong variability in the a-priori definition of vection, methodological inhomogeneity, varying approaches to the assessment of subjective vection measures and a lack of objective measures. We discuss the need for more qualitative research to reduce methodological inhomogenities, recommend future research in tactile-mediated vection to investigate stimulation to the torso, and suggest further investigation into the utility of concurrently presenting different forms of tactile stimulation.

“… 2 Auditory (e.g., Keshavarz et al., 2014 ; Mursic, Riecke, Apthorp, & Palmisano, 2017 ; Väljamäe, 2009 ) and tactile (e.g., Murata et al., 2014 ; Nordahl, Nilsson, Turchet, & Serafin, 2012 ) motion stimulation have both been reported to produce similar (although often less compelling) illusions of self-motion in blindfolded observers. Illusory self-motion can also be induced by passively rotating the limbs of blindfolded observers (e.g., Howard, Zacher, & Allison, 1998 ) or having them step on a treadmill (e.g., Bles, 1981 ).…”
Visually induced illusions of self-motion are often referred to as vection. This article developed and tested a model of responding to visually induced vection. We first constructed a mathematical model based on well-documented characteristics of vection and human behavioral responses to this illusion. We then conducted 10,000 virtual trial simulations using this Oscillating Potential Vection Model (OPVM). OPVM was used to generate simulated vection onset, duration, and magnitude responses for each of these trials. Finally, we compared the properties of OPVM’s simulated vection responses with real responses obtained in seven different laboratory-based vection experiments. The OPVM output was found to compare favorably with the empirically obtained vection data.
“…A depiction of the visual content of the abstract and naturalistic conditions can be found in Figure 3 A and B, respectively. The abstract auditory stimulus was an ascending Shepard-Risset glissando which has been shown to elicit vection [38], [39]. The naturalistic auditory stimulus was the sound of a train departing.…”
In the absence of physical motion, people sometimes experience the illusory sensation of self-motion which is known as vection. Vection and presence are positively related and vection research could contribute to the improvement of the fidelity of motion simulators. However, when utilizing Virtual Reality technology for motion simulators, visually-induced motion sickness (VIMS) in the form of Cybersickness (CS) sometimes co-occurs when one experiences vection. However, the relationship between vection and CS is not evident as, to the best of our knowledge, past research mainly investigated the relationship between the vection and CS with environments with a certain level of ecological relevance. Herein we aimed to investigate whether CS negatively affects the relationship between vection and presence across different virtual environments with varying levels of ecological relevance. We immersed twenty-nine participants visually and audibly in virtual environments and after each trial, participants reported their vection intensity, CS and presence. Our results showed that the relationship between vection intensity and presence was unaffected by CS. We conclude that the relationship between vection and presence is unaffected by CS with low levels of discomfort.
