항해사 workload 측정을 위한 기초연구

Abstract

The aim of this paper is to evaluate the ship navigator’s mental workload, we compared the variation of physiology signals according to the Operational Environments. The experiment was carried out in the KMOU training ship. The participants in this study were the captain, officer, and quarter master. We measured the ship navigator’s mental workload/performance based on ECG (Electrocardiogram), PVT (Psychomotor Vigilance Test) and NASA-TLX. The selected scenarios are arrival & departure between the ports of Busan and Ulsan. The results from ECG, PVT, and NASA-TLX analysis showed differences for arrival and departure. In the case of the captain, the results showed that the workload of arrival was higher than that of departure. In the cases of the officer and the quarter master, the results showed that the workload of departure was higher than that of arrival. Based on the results of this study, it will be possible to evaluate the workload under various conditions using a simulator. Further experiments were performed with a variety of participants.s in this study were the captain, officer, and quarter master.
