Evaluation of mixed culture bridge teammates' mental workload using heart rate variability: Simulator-based ship handling

Our goal is to evaluate quantitatively mental workload of a ship's bridge (bridge) teammate: navigator (captain), helmsman, and pilot. The greatest cause of much stress they feel is their treating cargo, infinite sum of money. Their roles in navigating to avoid a disaster at sea are so much large. The actualization to evaluate quantitatively mental workload is not just useful to relieve them of their much mental workload, but also to hand down a navigational skill to a new navigator from a veteran navigator; if we recognize the sea area where a veteran navigator feels mental workload, we understand the veteran navigator's navigating intend and a new navigator acquire and use the navigating skill like a veteran navigator. We use R-R Interval, one of physiological indices, to evaluate mental workload and we utilize the ship maneuvering simulator (simulator) to confirm the effectiveness of R-R Interval. In addition, we evaluate the mental workload of multinational bridge team.
