“…Prolonged exposure to visual yaw rotation (i.e., 20–30 min) may also induce symptoms of motion sickness (MS, e.g., [3–10]) which, in this case, is referred to as Visually Induced Motion Sickness (VIMS). Symptoms include stomach discomfort, nausea, oculomotor discomfort and dizziness.…”

Vection is the main contributor to motion sickness induced by visual yaw rotation: Implications for conflict and eye movement theories

This study investigated the role of vection (i.e., a visually induced sense of self-motion), optokinetic nystagmus (OKN), and inadvertent head movements in visually induced motion sickness (VIMS), evoked by yaw rotation of the visual surround. These three elements have all been proposed as contributing factors in VIMS, as they can be linked to different motion sickness theories. However, a full understanding of the role of each factor is still lacking because independent manipulation has proven difficult in the past. We adopted an integrative approach to the problem by obtaining measures of potentially relevant parameters in four experimental conditions and subsequently combining them in a linear mixed regression model. To that end, participants were exposed to visual yaw rotation in four separate sessions. Using a full factorial design, the OKN was manipulated by a fixation target (present/absent), and vection strength by introducing a conflict in the motion direction of the central and peripheral field of view (present/absent). In all conditions, head movements were minimized as much as possible. Measured parameters included vection strength, vection variability, OKN slow phase velocity, OKN frequency, the number of inadvertent head movements, and inadvertent head tilt. Results show that VIMS increases with vection strength, but that this relation varies among participants (R2 = 0.48). Regression parameters for vection variability, head and eye movement parameters were not significant. These results may seem to be in line with the Sensory Conflict theory on motion sickness, but we argue that a more detailed definition of the exact nature of the conflict is required to fully appreciate the relationship between vection and VIMS.

“…Most importantly, vection has been linked to visually induced MS (Hettinger, Berbaum, Kennedy, Dunlap, & Nolan, 1990;McCauley & Sharkey, 1992); and may be a precondition for visually induced MS (Crampton & Young, 1953;Smart, Stoffregen, & Bardy, 2002), as most users of virtual simulators who report sickness also experience vection (Hettinger et al). Vection itself is determined by a number of other factors, such as the participant's field of view (Brandt, Dichgans, & Koenig, 1973;IJsselsteijn, de Ridder, Freeman, Avons, & Bouwhuis, 2001) or even the color of the visual stimulus (Bonato & Bubka, 2006;Seno, Sunaga, & Ito, 2010).…”

Optic flow in visual displays or virtual environments often induces motion sickness (MS). We conducted two studies to analyze the effects of stereopsis, background sound, and realism (video vs. simulation) on the severity of MS and related feelings of immersion and vection. In Experiment 1, 79 participants watched either a 15-min-long video clip taken during a real roller coaster ride, or a precise simulation of the same ride. Additionally, half of the participants watched the movie in 2D, and the other half in 3D. MS was measured using the Simulator Sickness Questionnaire (SSQ) and the Fast Motion Sickness Scale (FMS). Results showed a significant interaction for both variables, indicating highest sickness scores for the real roller coaster video presented in 3D, while all other videos provoked less MS and did not differ among one another. In Experiment 2, 69 subjects were exposed to a video captured during a bicycle ride. Viewing mode (3D vs. 2D) and sound (on vs. off) were varied between subjects. Response measures were the same as in Experiment 1. Results showed a significant effect of stereopsis; MS was more severe for 3D presentation. Sound did not have a significant effect. Taken together, stereoscopic viewing played a crucial role in MS in both experiments. Our findings imply that stereoscopic videos can amplify visual discomfort and should be handled with care.

“…Most of the power in spectral density analyses of body sway is below .40 Hz (Bensel & D2endolet, 1968) and perhaps platform stimuli in this range could be amplified at the head. Although acceleration of the environment is generally required, visual motion alone is sufficient to produce sickness (Crampton & Young, 1953;Dichgans & Brandt, 1M73).…”
