“…Keshavarz et al suggested in 2019 that vection is a necessary prerequisite, but not a sufficient condition, for inducing VIMS. Moreover, in certain conditions, the effect of SoP in VR has a positive correlation with vection [10], but is negatively associated with VIMS [12].…”

“…In the virtual Roller Coaster simulation, VIMS scores had a positive correlation with the maximum nausea score during the ride and a negative correlation with the duration of the ride [1,9]. However, the illusory sensations of own body movement (vection) and VIMS are not identical and have a complex indirect connection, because vection may occur without VIMS [10] and vice versa [11]. For example, Keshavarz et al found that stimulus' density, speed, and rotations can alter the illusory sensations of self-motion and have additive effects, which is not associated with the VIMS [10].…”

The evolution of virtual reality (VR) technologies requires setting boundaries of its use. In this study, 3 female participants were experiencing VR scenarios with stressful content and their activity of the autonomic nervous system and EEG were recorded. It has been discovered that virtual reality can evoke acute stress reactions accompanied by activation of the sympathetic nervous system and a decrease in the activity of the parasympathetic nervous system. The high-stress response is accompanied by a decrease in the power of the EEG, and, on the contrary, the activation of the avoidance reaction is accompanied by an increase in the power of the EEG alpha waves. Therefore, the use of stressful VR content can cause high emotional stress to a user and restrictions should be considered.

“…To achieve this, we exposed our participants to a potentially nauseating optic flow stimulus (starfield) in a VRsetup using an HMD. The starfield stimulus was chosen based on the theoretical and methodological considerations of Keshavarz et al (2019), who successfully induced VIMS with this type of stimulus. To provide a meaningful stimulus, we designed a timeto-contact (TTC) task to be performed during the experiment.…”

Visually induced motion sickness is an unpleasant but common side-effect of many simulations and VR-applications. We investigated whether an earth-fixed reference frame provided in the simulation is able to reduce motion sickness. To do so, we created a moving starfield that did not contain any indicators of the spatial orientation of the observer. As the observer was simulated to move through the randomly oscillating starfield, a time-to-contact task had to be carried out. Two colored stars on collision course with each other had to be spotted, then they disappeared and the time of their collision had to be judged. Eye-movements, task performance, and motion sickness were recorded. This condition without visual reference to the observer's upright was supplemented with three conditions containing either an earth-fixed fixation cross, an earth-fixed horizon line, or a line that was yoked to the head. Results show that only the earth-fixed horizon was able to significantly reduce visually induced motion sickness. Thus, a mere earth-stationary anchor does not suffice, a clear indication of earth horizontal seems necessary to reap a modest benefit.

“…They often undergo MS training in the first 2-3 days in microgravity environment and the first few days after returning to earth [3]. MS is commonly used during the simulated flight training for astronauts or pilots [4]. Therefore, MS sensitivity assessment is particularly necessary for selecting pilot trainees, training quasi-pilot personnel and assessment before the restoration of the flight and after the vestibular damage is recovered [5,6], etc.…”

ObjectiveThe main goal of our study is to clarify the EEG characteristics of the stress response caused by vestibular endurance training under the real conditions.MethodsTen pilot trainees received a series of acute anti-vertigo training stimulations on the rotary ladder while recording electroencephalographic data (64 electrodes). Afterwards, the subject’s anti-vertigo ability was tested for the best performance after 1 month of training, and verifying whether it is relating to the EEG signals we collected before.Results(1) The absolute power of α waves in the C3 and C4 regions is same as the difference between 1 min before and 2 min after stimulation, and their activity is enhanced by stimulation. Otherwise, the activation of the C3 region after 5min of stimulation is still significant changed. (2) Discover a spearman rank correlation, the α waves in the C3 and C4 the greater the power change, the better the performance of the subject in the proficient stage.ConclusionsC3 and C4 areas are specific brain regions of the stress response of anti-vertigo endurance training, and the absolute power of the α wave can be used as a parameter for identifying the degree of motion sickness (MS). The absolute power changes of α waves in the C3 and C4 areas are positively correlated with their anti-vertigo potential.SignificanceThe increasing of the absolute power of α wave in the C3 and C4 is a manifestation of MS stress adaptability.
