A navigator guides a ship for safe and efficient navigation, and s/he gets navigational information through the five senses. Visual information is most important because it is said to occupy more than eighty percents to whole information. We are researching the relationship between the visual image of seascape and the physiological/body response using ship bridge simulator, which is used to train...
Mental workload is useful for evaluating performance of a ship's navigator: a captain, a duty officer, and a pilot. The heart rate variability (R-R interval), the nasal temperature and the salivary amylase predict well based on pre-experiments; however, most of the research tests a professional's skill. The evaluation does not test a cadet's skill yet. In this paper, we evaluate a cadet's R-R interval...
Mental workload is useful to evaluate performance of ship bridge teammates: a captain, a duty officer, a helmsman, and a pilot. The physiological indices, heart rate variability (R-R interval) and nasal temperature, represent their mental workload in ship handling. Moreover, we have found a salivary amylase as a good index for evaluating the mental workload of the navigator. The salivary amylase activity...
