Abstract
Objective evaluation methods of visual induced motion sickness (VIMS) caused by interactive video such as computer game is studied to clarify the relation between VIMS and image motion components. We focus on time-variant biosignal indices related autonomic nervous activity, and estimate availability of two indices called ΔILF/HF based on LF/HF ratio and triggerpoints from heart rate signals. As a result of experiment by 20 subjects, the biosignal indices have positive correlation with the global motion of video in case of non-interactive video, whether unpleasant subjective score is low or high. In case of interactive video, on the other hand, both subjective score and triggerpoints by biosignal decrease compare to that of non-interactive video, and ΔILF/HF indices tendency depends on the operation type of video in case of interactive video. These results suggest that triggerpoints indices are possible to use for evaluation of VIMS related by GMV, and ΔILF/HF indices are possible to use unconscious VIMS effect in ANA level caused by video motion and operation rather than subjective unpleasant sensation.
