The purpose of this study is to test eye tracking in studying the usability of electronic chart display and information systems (ECDIS), one of the major components of ships’ bridge navigation systems. The carriage and adequate use of ECDIS on merchant ships is mandated by international regulations to improve maritime safety. The aim of this study is to test eye tracking as an assessment tool for usability of ECDIS. Eye movement data, collected from experienced port pilots operating on three different models of ECDIS, was analysed for the study. Significant differences were found between time to first fixation measurements among three different ECDIS models, as well as differences in heat map visualisations between the participant port pilots and expert users. The results indicate that eye tracking is an effective tool for assessment of the usability of ECDIS. The study, aiming potentially to improve the effectiveness of bridge navigation systems, proposes the integration of eye tracking in research and development of ECDIS, and contributes scientifically to research on eye tracking in marine transportation.

电子海图显示和信息系统可用性中的眼动追踪

本研究的目的是测试眼动追踪在研究电子海图显示和信息系统 (ECDIS) 的可用性方面，ECDIS 是船舶驾驶台导航系统的主要组成部分之一。国际法规要求在商船上运输和充分使用 ECDIS，以提高海上安全。本研究的目的是测试眼动追踪作为 ECDIS 可用性的评估工具。研究分析了从使用三种不同型号的 ECDIS 操作的经验丰富的港口引航员那里收集的眼动数据。在三种不同的 ECDIS 模型中，首次固定测量的时间之间存在显着差异，参与港口引航员和专家用户之间的热图可视化也存在差异。结果表明，眼动追踪是评估 ECDIS 可用性的有效工具。该研究旨在提高桥梁导航系统的有效性，提出将眼动追踪整合到ECDIS的研发中，并为海洋运输中的眼动追踪研究做出科学贡献。
