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...
This paper describes the evaluation of mental workload of specialists for ship handling. We evaluate the specialists' performance using a real ship. We show the effect of physiological indices from the specialists' performance and the characteristics of their mental workload with heart rate (heart rate variability: R-R interval), nasal temperature and salivary amylase activity. In this paper, we confirm...
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 and nasal temperature, are good indices of the mental workload found in ship handling; however, it is best if we get response and evaluation results quickly on the spot. A recent study shows salivary amylase activity is reflected...
In Japan, an evaluation of on-board ship handling training depends on professionals who have a lot of experience on board. This style is common for human skill practices worldwide. However, it is difficult for a cadet to understand his progress, because real ship training includes every distraction; the same case never happens in his student life. On the other hand, the knowledge is easy to learn...
Mental workload is useful to evaluate performance of a ship's bridge teammate: a captain, a duty officer and a helmsman, sometimes adding a pilot. The heart rate variability and the nasal temperature predict well based on pre-experiments; however, we have not evaluated them at the same time yet. In this paper, we evaluate simultaneously heart rate variability and nasal temperature of a subject as...
