An Evaluation of Mental Workload for Effective Navigation
Murai, Koji; Hayashi, Yuji
Interactive Technology and Smart Education, v5 n1 p29-38 2008
Purpose: This paper aims to propose that the nasal temperature is an effective index to evaluate the mental workload of a navigator for effective navigation. Design/methodology/approach: The evaluation comes from the actual on-board experiment, not simulation. The subject is real bridge teammates; captain, duty officer, and quarter master. The mental workload is evaluated for a lot of navigational situations. Findings: The nasal temperature responds when the navigator makes a decision regarding ship-handling and collision avoidance, and shows well the whole trend of his decision-making. Then the nasal temperature takes effect to evaluate the bridge team work among captain, duty officer and quarter master. Research limitations/implications: Future research is to make cross-indices with the nasal temperature and the heart rate variability (R-R interval) complementary to each other where the nasal temperature registers the trend and the R-R interval registers the quick response of the mental workload. Practical implications: The paper describes the effective index which is useful to evaluate bridge teammates' mental workload for effective navigation. Originality/value: Navigator's skill has been evaluated according to behavior (performance) and a questionnaire as a quantitative evaluation; moreover, the mental workload tries to do it using nasal temperature and heart rate variability.
