Effect of LCDs displaying blurred images on the postural control system.
In order to evaluate display devices, a geostationary image and the character were generally used in previous studies. We have proposed a new method for comparing the standing posture when a subject views a liquid crystal display (LCD) displaying a movie scrolling from the left to the right. In this study, we mathematically measured the degree of determinism in the dynamics of the sway of center-of-gravity. The Double-Wayland algorithm was used as a novel method. As a result, the dynamics of the sway when subjects viewed the movie as well that of the sway in the resting state was considered to be stochastic. The moving map task would not change it into a deterministic one.
