A Knowledge Discovery in Motion Sickness: A Comprehensive Literature Review

Motion sickness is a common perturbation experienced by humans in response to motion stimuli. The motion can happen in either real or virtual environments perceived by the vestibular system and visual illusion. The extensive varieties of research studies have been conducted in order to determine and evaluate aspects of motion sickness and its symptoms. To provide insights upon physiological changes in regards to motion sickness, researchers have used subjects from different ages, gender in addition to electrode positions and environmental conditions. The main purpose of this study is to provide a comprehensive review and comparison of the existing research studies regarding aspects of interference of the existence and augmentation of motion sickness. In this paper, we discuss the appearance of symptoms after motion sickness and summarize the physiological behaviors and emotions via a range of scenarios. In addition, the existing methods for measuring motion sickness levels are compared and discussed in detail. This study considers a number of important factors such as age, gender, health condition, participants (non/fatigue or non/drowsiness), road conditions, and different experimental set-ups impacting the results of motion sickness. Finally, this paper presents a range of practical methods to minimize and prevent the unpleasant side effects of motion sickness. This includes air ventilation, homogenized road/virtual environment features, and providing comfortable set-up and pre-movement before visual acceleration. A deeper understanding of changes in physiological signals during vection helps us to confirm the traditional subjective report and also improves our knowledge in the concept the vection.
