Relationship between Physiological Indices and a Subjective Score in Evaluating Visually Induced Motion Sickness

Abstract

Visual environments are evolving rapidly along with the popularization of high resolution and wide field-of-view displays. However, there is a concern that these environments may give negative effects on viewers' health such as visually-induced motion sickness (VIMS). Previous studies reported that some physiological indices were useful to assess the effect of visual stimulation. However, we have little knowledge about temporal relationship between the severity of sickness and the change in the physiological indices. In this study, the average mutual information has been employed to investigate this relationship. The analysis of experimental data has suggested that there is a possibility to detect a sign of VIMS prior to the development of symptoms of VIMS with the physiological indices.
