It is very important to clarify some objective indices, which can demonstrate one's physical condition of motion sickness. The authors proposed an analysis method using the fluctuation of heartbeat for this purpose. The CGSA (Coarse Graining Spectral Analysis) method was developed in the field of medicine, and it is reported that this method is effective to distinguish fractal component from wideband signal. The CGSA method was applied to one's heartbeat fluctuation through the stages of motion sickness incidence in this paper. Some physiological indices of the relative stress, the relaxation rate, and the percent fractal are introduced to compare them with the subject's psychological changes. The authors showed that the CGSA method is also thought to be useful to understand the subjects' physiological and psychological condition objectively, but more subjects' results are necessary to clarify the relationship between subject's motion-sickness degree and some indices of mental stresses and/or relaxation.
