Comparison study of real ship-simulator for ship navigator’s workload assessment

Abstract

The aim of this paper is to evaluate the ship navigator’s mental workload we compared the variation of physiological signals using a real ship and a simulator. The experiment was carried out on the training ship of the KMOU and at the Full Mission Simulator of KRISO. The subjects in this study are the captain and the officer. 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 and departure in Busan. The results from ECG and NASA-TLX analysis showed a similar tendency between the simulator and the training ship. Therefore, to analyze the mental workload of the ship navigator, it is necessary to engage in a continual accumulation of data. Further experiments were performed with a variety of subjects. Based on the results of this study, it will be possible to evaluate the workload under various conditions using a simulator.
