Abstract
The purpose of this paper is to find relations between the body and physiological response to visual simulation of ship rolling and the horizontal visual field. We carry out the experiment that is simulated ship rolling only visually and not mechanically from zero to eight meters wave height at one meters interval for four kinds of horizontal visual field (210°, 150°, 90° and 30°) using the ship handling simulator at Kobe University of Mercantile Marine. We measure subjects gravity center and R-R interval for body and physiological response to the artificially created visual environment. The subjects look visual environment for three minutes in each wave condition. Here, subjects are three experienced persons (navigators) and three inexperienced persons.
The results showed that the displacement of navigators gravity center were led toward an inclination of the picture created by the simulator with wide horizontal visual field. And the relations between rolling angle and locus length of gravity center took the peak point for all horizontal visual fields. Also, the index with R-R interval and locus length of gravity center were correlated for 210° horizontal visual field.
From the results, we knew the realistic image with wide horizontal visual filed was influenced on the subject's body and physiology, and it's characteristics was difference between experienced persons and inexperienced persons.
