Development of a HUD-based Integrated Navigation Information System User Interface for Effective Autonomous Ship Navigation

Various AI-based digital navigation technologies, such as autonomous navigation, are being developed in the maritime shipping industry.It is necessary to effectively integrate the information provided individually by various navigation information systems installed on a ship and efficiently deliver it to navigators to realize the first stage of autonomous navigation, known as an onboard decision support ship.In this study, we developed a user interface for an HUD-based integrated navigation information system that supports navigators in performing navigation tasks safely and efficiently.Through a literature review and expert interviews, the detailed procedures of navigation tasks and pain points from the perspective of practitioners were investigated, and three types of user interfaces (lookout-focused, information-focused, and nighttime-supportive) that can be selectively used depending on the context were proposed.The user interface proposed in this study is expected to be useful in the development of navigation information systems for autonomous ships.
