Situation awareness and mental workload of navigator in ship maneuvering simulator

摘要

Evading navigation in heavy marine traffic area required high navigation skill for navigator. Ship maneuvering simulator training was effective to improve their navigation skill. For the effective training, it was important that subject appropriately recognized ships that had collision risk. In order to measure navigator's situation awareness in simulator training, situation awareness global assessment technique was useful. However, in the case of ship maneuvering simulator training, accuracy of the measured data was insufficient. In order to clarify the reason for insufficient accuracy, this study measured navigator's situation awareness and mental workload in ship maneuvering simulator. As a result, this paper indicated that subjects who got appropriate tension during the simulation run had appropriate situation awareness.
