Abstract

In this paper, it is proposed that the effects of simulator sickness due to scene movement in ship handling simulator can be measured by using center of pressure (COP) and a simulator sickness questionnaire (SSQ). For experiments of simulator sickness, twelve participants are exposed to scenes movement from ship handling simulator according to three steps of sea states. During experiments, COPs for subjects are measured by force plate. After exposure to scenes movement, subjects describe their sickness symptoms by answering the SSQ. Throughput analysing the results of scene movement, SSQ, and COP, the relation between the simulator sickness and COP is investigated. It is suggested that formulations for SSQ score and COP with respect to sea state are obtained by the curve fitting technique, and the longitudinal COP can be used for measuring the simulator sickness.

본 연구에서는 시각적 동요를 기반으로 하는 선박운항 시뮬레이터(ship handling simulator)에서 시뮬레이터 멀미 설문(SSQ, simulator sickness questionnaire)과 압력 중심(COP, Center Of Pressure)을 이용하여 시뮬레이터 멀미(simulator sickness)를 계측할 수 있는 기법을 제안한다. 실험을 위하여 선박운항시뮬레이터에서 피실험자가 시각적 동요에 노출되도록 하였고 해상상태(sea state)를 3단계로 바꾸어 가며 실험을 수행하였다. 시각적 동요 노출의 직후에 피실험자는 SSQ를 통하여 실험동안의 자각증상에 대한 설문을 작성하였고, 시각적 노출중에는 지면반발력계를 이용하여 피실험자의 COP를 측정하였다. 시각적 동요, SSQ, 그리고 COP의 데이터 분석을 통하여 시뮬레이터 멀미와 피실험자의 COP 사이의 연관성을 고찰하였다. 실험 및 분석을 통하여 해상상태에 따른 SSQ 점수와 피실험자 COP에 대한 각각 관계식을 제시하였고, 피실험자의 종방향 COP가 시뮬레이터 멀미 계측을 위한 지수로 활용될 수 있음을 보였다.
