顔面皮膚温による操船者の心的負荷の定量的評価

摘要

When captains and deck officers on training ships evaluate cadets' performance for ship handling, they usually do it by their experience. Therefore, their evaluations are not stable and luck of persuasion. For solving this problem, it is necessary to develop objective and quantitative evaluation of ship navigator's ability for ship handling. It is popular to use SNS values calculated from heart beats for the evaluation. For improving the evaluation, it is necessary to innovate new indexes from human body.rnhi this paper, we focus on facial temperature for the new index especially nose and forehead temperatures. These temperatures are measured by a thermography on board, and the difference between them is useful for the evaluations as same as SNS values. We apply the index to the evaluation of difficulty scale for ship handling and discuss the ability of the new index.%本論文では鼻部皮膚温が自律神経系の活動に影響を受けるという特徴を利用して、操船時の心的負荷の評価を行った。被験者が操船する時にその顔面をサーモグラフィーで撮影し、顔面皮膚温を測定した。そして、得られた鼻部前額部皮膚温差と心的負荷の関係や被験者の行動との関係について考察を行った。本論で明らかになったことは以下のとおりである。
