Study of A Port Coordinator's Mental Workload Based on Facial Temperature

Abstract A physiological index is able to evaluate the mental workload of a ship's bridge teammate; a captain, a duty officer and a helmsman, sometime adding a pilot. The facial (nasal) temperature reads the mental workload well, and it has been confirmed by the past experiments; however, we do not evaluate a port coordinator, who supports to keep safe navigation in a bay and a harbour by supplying an useful information to a navigator, yet. The safe of bay and harbour is kept by teamwork among a ship, a government, and an agency and so on. We aim at the port coordinator in this study because their information is an important for safe navigation, and their mental workload shows the traffic condition of the bay and the harbour. Moreover, to understand their mental workload develops how to supply the useful and efficiency information to the vessels. In this study, we evaluate the nasal temperature while they serve as the port coordinator. The experiment is carried out at Hakata port radio. We show the nasal temperature is fine index to monitor their mental workload.
