Evaluation of the mental workload during training for ship handling has usually depended on professionals (captain, pilot) who have lots of experience on board. We are attempting to evaluate a ship navigator%26apos;s mental workload based on a physiological index. The physiological indices, namely heart rate variability (R-R interval), nasal temperature, and salivary amylase, are good indices for reading the mental workload during ship handling. Moreover, we find the possibility of using salivary NO3- as a good index for evaluating the ship navigator%26apos;s mental workload. Salivary NO3- is expected to have a specific characteristic to represent quick response on the spot and the trend. We confirmed the response of students during simulator training, and then carried out the experiment on professionals on a real ship. We propose that salivary NO3- can show a ship navigator%26apos;s stress for ship handling in the simulator and on a real ship. This work to evaluate the ship navigator%26apos;s mental workload using salivary NO3- is the first attempt worldwide.
