Measuring the 'reality' given by highly realistic surrounding display systems toward modeling based on dynamical systems theory

摘要

The goal of this study is to develop a quantitative method of evaluation of observer's impression called "feeling of immersion" when visual stimulus is displayed on a surrounding-display. We introduced a method uses movement of observer s center-of-gravity (body-sway) induced by the visual stimulus as an index. To develop a dynamical model of movement of observer's center-of-gravity (body-sway) induced by the visual stimulus, we examined dynamics of stance posture control in tracking and of visually-induced self movement. The results suggested that a dynamical model of visually-induced self movement requires functions of learning and preview dynamics of stimulus.
