Ship-Motion Simulator and Measurements of Motion-Sickness Incidence

Abstract

The authors introduce a ship-motion simulator which will make it possible to carry out experimental studies on motion-sickness and ride-quality of ships and other vehicles. The purpose of the laboratory experiments by using the ship-motion simulator is to make clear the mechanism of the motion-sickness incidence. For this, it is necessary to carry out many experiments under the same situational conditions. Physiological measurements such as electroencephalogram, electrocardiogram, sweating, blood pressure and pulse, as well as facial expressions of subjects exposed to low frequency whole-body oscillation. At the same time, psychological changes of the subjects during the oscillations are also measured. Some examples of measured results are reported in the paper.
