“…Techniques for preventing cybersickness include adaptation to VR through repeated exposure (Barrett 2004;Keshavarz 2013), designing VR environments to include stable visual references of the horizon or perceptual vertical (Han et al 2011), developing applications based on physical locomotion (Llorach et al 2014), and providing concurrent vestibular signals by means of galvanic vestibular stimulation (Cevette et al 2012).…”

In the past decade, there has been a rapid advance in Virtual Reality (VR) technology. Key to the user’s VR experience are multimodal interactions involving all senses. The human brain must integrate real-time vision, hearing, vestibular and proprioceptive inputs to produce the compelling and captivating feeling of immersion in a VR environment. A serious problem with VR is that users may develop symptoms similar to motion sickness, a malady called cybersickness. At present the underlying cause of cybersickness is not yet fully understood. Cybersickness may be due to a discrepancy between the sensory signals which provide information about the body’s orientation and motion: in many VR applications, optic flow elicits an illusory sensation of motion which tells users that they are moving in a certain direction with certain acceleration. However, since users are not actually moving, their proprioceptive and vestibular organs provide no cues of self-motion. These conflicting signals may lead to sensory discrepancies and eventually cybersickness. Here we review the current literature to develop a conceptual scheme for understanding the neural mechanisms of cybersickness. We discuss an approach to cybersickness based on sensory cue integration, focusing on the dynamic re-weighting of visual and vestibular signals for self-motion.

“…For instance, Diamond and Markham (1991) found differences in spontaneous ocular torsion between astronauts who experienced sickness during space-flight compared to those who did not. Recent efforts to reduce visual-vestibular cue mismatch in VR support a partial vestibular basis for CS: Both galvanic vestibular stimulation (Cevette et al, 2012;Gálvez-García et al, 2015;Reed-Jones et al, 2007) and bone vibration applied near the vestibular organs (Weech et al, 2018) reduce the level of CS experienced during VR use. There is also a striking similarity between CS symptoms and the symptoms of vestibular labyrinthectomy-although the former are less severe than the latterwith the effects of labyrinthectomy including "nausea and vomiting… excessive perspiration……”

The user base of the virtual reality (VR) medium is growing, and many of these users will experience cybersickness. Accounting for the vast inter-individual variability in cybersickness forms a pivotal step in solving the issue. Most studies of cybersickness focus on a single factor (e.g., balance, sex, vection), while other contributors are overlooked. Here, we characterize the complex relationship between cybersickness and several indices of sensorimotor processing. In a single session, we conducted a battery of tests of balance control, vection responses, and vestibular sensitivity to self-motion. A principal components regression model, primarily composed of balance control measures during vection, significantly predicted 37% of the variability in cybersickness measures. We observed strong, inverse associations between measures of sway and cybersickness. The results reiterate that the relationship between balance control and cybersickness is anything but straightforward. We discuss other factors that may account for the remaining variance in cybersickness.

“…GVS was integrated in the simulator program to combine visual and vestibular stimulation (OVR simulation) [for technical details, see Cevette et al ( 2 )]. Visual input was then projected onto a 180° cylindrical screen in front of the subject.…”

“…However, to the best of our knowledge, no studies have evaluated the role of EGG in quantifying the effect of GVS in mitigating SS. We recently showed that the implementation of GVS in a visual fl ight simulator [oculovestibularrecoupled (OVR) stimulation] minimizes the intersensory confl ict that is thought to provoke symptoms such as nausea, vomiting, and dizziness ( 2 ). Therefore, the aims of the current study were: 1) to quantify EGG responses in two groups of subjects during fl ight simulation with or without OVR; 2) to correlate EGG responses with subjective reporting of SS with or without OVR; and 3) to correlate vestibulo-autonomic [cardiac interbeat interval (IBI) or HRV] responses with subjective reporting of SS with or without OVR.…”
