| Research Abstract |
The aim of this study was to develop the evaluation method for the effect of the various unnatural video components such as excessive motion on viewers. In order to achieve this object, a new physiological index of autonomic nerve activity relating to vascular regulation was proposed. The model which represents the relationship between video motion and a degree of discomfort was also proposed using non-linear Hammerstein model, in which the discomfort level was estimated by using a multiple regression model whose explanatory variables ware several physiological indices including the proposed vascular index. The model could explain the change in a degree of discomfort with a correlation coefficient of 0.74. It seems that these results can contribute to an objective assessment of visual image safety.
