Summary: This study evaluated changes in postural control and psychophysical state in novice pilots after exposure to flight simulator conditions. The results indicated that simulator training can lead to symptoms of simulator sickness, with reduced postural stability and increased SSQ scores.

Summary: Research shows that self-initiated optic flow can lead to left-lateralized inhibition of posterior event-related alpha desynchronization in the brain, as well as stabilization of postural responses. Additionally, self-initiation also produces a large event-related potential negativity between 130-170 ms after optic flow onset.

Summary: The study found that among pre-adolescent children, controlling a virtual vehicle reduces the risk of motion sickness compared to being a passenger. Drivers were less likely to experience motion sickness than passengers, and displayed different characteristics in movement.

Summary: The purpose of this study is to estimate individual susceptibility to motion sickness by linking pre-exposure measures of seated postural sway with subjective ratings of visually induced motion sickness (VIMS), using a head-mounted display (HMD) to show a roller coaster movie. Participants watched the content for 15 minutes, and their seated center of pressure (sCOP) was measured for 5 minutes before viewing. A VIMS estimating model was developed and verified, with strong correlations between SSQ scores for VIMS and the area, main-to-minor ratio, and total length of sCOP. The accuracy of classifying VIMS severity using RUSBoost was 0.74.

Summary: Virtual reality can cause cybersickness, with deteriorations in postural stability possibly predicting or objectively measuring the sickness, but individual differences and overlapping symptoms complicate the relationship.

Summary: Motion sickness (MS) and postural control (PC) conditions are common complaints among passive travelers. The sensory conflict theory is the most prominent explanation for MS, stating that a mismatch between vestibular and visual signals causes it. A novel multimetric system called BioVRSea was introduced for studying the physiology associated with MS and seasickness, utilizing virtual reality technology and biomedical sensors. This study identified muscle parameters as most significant in machine learning classification, with the EEG parameters being less important. The research serves as a first step in identifying key physiological factors that differentiate individuals suffering from MS from those who do not using the BioVRSea system.

Summary: This study aimed to examine the effects of CD on linear motion perception, hypothesizing impaired heading discrimination in both vestibular and visual tasks, and that such deficits correlate with the disease severity.

Summary: In addition to anthropometric variables, high-order body representations have been found to influence postural control, especially in females. Body image and body schema were assessed through tasks involving figural drawing and covert/overt measures. The study revealed that body schema was significantly associated with postural control, along with other factors such as sensory condition, gender, age, and anthropometry. In females, body image dissatisfaction also played a substantial role in postural control, while this was not the case in males. The study discusses sex differences and potential reasons why high-order body representations may influence concurrent sensorimotor control of body sway.

Summary: This study conducted a comprehensive systematic review and meta-analysis on the effects of active video game (AVG) interventions on postural balance. The findings suggest that AVG interventions can improve postural balance in populations of all ages with or without neurologic impairments.

Summary: The visual contribution to the perceptual and postural vertical decreases with age in children, with the youngest age group showing the greatest effects and the oldest age group exhibiting the highest susceptibility to motion sickness.

Summary: Individuals with MS show poorer standing postural control during ML visual oscillations compared to controls, and blocking vision of the lower peripheral field can reduce overall sway in individuals with MS.

Summary: Previous studies have not assessed and compared 2D and 3D images or video clips. There is also a lack of unified assessment methods or standards for evaluating 3D video clips. Personal attributes of viewers, such as sex and corrected eyesight, have not been considered in previous evaluations. This study conducted a questionnaire survey and experimental evaluation to investigate the viewing experience of 3D video clips and the influence of personal characteristics on visually induced motion sickness.

Summary: Repeated exposure to virtual reality can reduce the severity of cybersickness. This study investigated the exposure conditions required to reduce cybersickness in head-mounted display (HMD) VR and whether these reductions generalize to different games. Findings showed that repeated exposure to the same HMD VR game significantly reduced cybersickness, but this effect did not transfer to other games.
