This article first provides an overview of the past and current clinical applications of VR systems in neurology and psychiatry and introduces core concepts in neurophilosophy and VR research (such as agency, trust, presence, and others). The improved technological capabilities of these systems as well as the combination with biometric sensors, for example electroencephalography (EEG), in a closed-loop hybrid VR-EEG, opens up a range of new potential medical applications. Highly immersive virtual reality (VR) systems have been introduced into the consumer market in recent years. The results indicate that the floor vibration significantly reduced some measures of cybersickness. Other variables differed between groups in the same direction, but with trivial or small effect sizes. Comparing data between participants in the Vibration group (N=11) to the No-Vibration group (N=11), we found that Delta-SSQ Oculomotor response and the GSR physiological signal, both known to be positively correlated with cybersickness, were significantly lower (with large effect sizes) for the Vibration group. These included presence and simulator sickness questionnaires (SSQ), self-rated discomfort levels, and the physiological signals of heart rate, galvanic skin response (GSR), and pupil size. We collected subjective and objective data for variables previously shown to be related to levels of cybersickness or presence. The scenario and driving conditions were designed to be cybersickness-inducing for users in both the Vibration and No-vibration conditions. We programmed the floor to generate vertical vibrations similar to those experienced in real off-road vehicle travel. To evaluate the system, we implemented a realistic off-road vehicle driving simulator in which participants rode multiple laps as passengers on an off-road course. We integrated a custom-built, computer-controlled vibrating floor in our VR system. Starting from sensory conflict theory, we posit that if a vibrating floor delivers vestibular stimuli that minimally match the vibration characteristics of a scenario, the size of the conflict between the visual and vestibular senses will be reduced and, thus, the incidence and/or severity of cybersickness will also be reduced. , a major barrier to successful long-exposure immersive virtual reality (VR) experiences since user discomfort frequently leads to prematurely ending such experiences. In this paper, we compare the effects of cybersickness between the people with MS and the people without MS with respect to SSQ score and GSR data. However, participants with MS had significantly lower GSR during VR exposure. The GSR data suggests that the cybersickness may have induced similar physiological changes in participants with MS as participants without MS, albeit with greater variability in participants without MS. SSQ results show that the VE induced cybersickness in the participants. Also, Simulator Sickness Questionnaire (SSQ) feedback was recorded before and after the experiment. We collected Galvanic Skin response (GSR) data before and during VR exposure GSR is commonly used as an objective measure of cybersickness. We asked each participant to experience a VE. Two participants from population without MS could not complete the experiment due to severe cybersickness. For this experiment, we recruited 16 participants - 8 persons with MS and 8 persons without MS from similar demographics (e.g. This is an important area of research because cybersickness could have negative effects on virtual rehabilitation effectiveness and the accessibility of VEs. Although there have been many cybersickness experiments conducted with persons without disabilities, persons with disabilities, such as Multiple Sclerosis (MS), have been minimally studied. It has symptoms similar to Motion Sickness, such as dizziness, nausea etc. Cybersickness is commonly experienced by the users in immersive Virtual Environments (VE).
