Basic study of ship´s bridge teammate´s mental workload by wavelet transform

Specialists who have a lot of experience educate students on the ship. However, the contents of the practical on-board education are not always clear to the students, because real situations include all things, not just simple linear knowledge. Real life, complex situations are difficult for them to understand it. We need some evaluation indices of navigational art/skill (performance) which conform the basis of the shiphandling in on-board education. So, we have been researching how to evaluate human navigators´ performance using their physiological and behavioral information; however, our subject is just the navigator, not include a quartermaster and other bridge teammates. We need an advance evaluation including the bridge teammates except for the navigator. Also, the vessels with which we always are carried out the experiment are training ships, not general merchant ships. This paper describes the characteristics of the bridge teammates´ mental workload for the merchant ships by wavelet transform, and we confirmed the response to the performance for the shiphandling is clear.
