Outline of Final Research Achievements	Operators who engaged in vessel traffic services provide a variety of information to vessels in order to enhance the safety and efficiency of marine traffic. In this study, fixation time of the operator’s eye were analyzed using two eye tracking devices to investigate the real work of VTS operators in Japan and Korea. In Japan's Shimizu Port Radio, operators usually work in pairs, and the analysis of equipment and materials in the operation room as areas of interest showed a tendency for work assignment to be determined by the arrangement of the equipment. In the Korean VTS, one operator was in charge of each control area, and it was found that the gaze was often stationed on the screen where information was collected and provided, but that emphasis was also placed on recording in the control logbook.
Free Research Field	海上交通工学
Academic Significance and Societal Importance of the Research Achievements	船舶運航における【操船者―船―環境】の連関システムにおいて、操船者に対して海上交通に関する情報提供を行うVTSは情報環境の1つに分類される。故にVTSオペレーターの作業環境を改善することは、オペレーター自身のヒューマンエラー防止につながるだけでなく、より安全且つ効率的な海上交通の達成につながる。本研究では、オペレーターの視線情報からその業務実態を大凡把握できることを示し、設備・機器の配置状況といった作業環境により、自ずと業務分担が決まってくることが示唆された。換言すれば、業務内容がある程度決まっている場合には、器類の最適な配置設計がなされているか否かの検証が可能となる。
