Many maritime accidents have been caused by human-error including such things as inadequate watch keeping and/or mistakes in ship handling. Also, new navigation equipment, integrated by advanced IT technologies, presently support navigators in ensuring the safe navigation of ships. Despite these efforts, the reduction of maritime accidents has not occurred to the degree expected because, navigational equipment provides too much information, and this information is not well organized, such that users feel it to be complicated rather than helpful. In this point of view, the method of representation of navigational information is more important than the quantity of that information and research is required on the representation of information to make that information more easily understood and to allow decisions to be made correctly and promptly. To address this issue, a navigation support system utilizing Augmented Reality(AR) technology as a means of information delivery was proposed in this study. The proposed system overlays various navigational information on a real world image from a camera, allowing the navigator to make accurate and swift decisions regarding navigation and the final goal of the system is to reduce the workload of the ship officer. The prototype system was made by integrating these hardware and software modules, and the prototype system was applied as a ship-handling simulator, for real vessel application testing. The experiment results demonstrated that the prototype could operate normally with other navigational equipment in the simulator and bridge environment. In addition to the application testing, a survey was conducted evaluating the level of satisfaction and usability of the implemented functions. Analysis of the results showed positive responses for satisfaction and the usability of each function, with some improvements necessary for functionality. In particular, the traffic-ship information displayed near the horizon was displayed to be too dense to allow features to be conveniently distinguished. Interviews with navigators were conducted after the experiment to collect opinions on the augmented reality navigation support system, and it was found that some officers experienced a sense of burden due to the increased workload when using the new augmented reality navigational equipment. In this way, this study determined the problems involved when applying an augmented reality navigational support system concept to the bridge environment. Its applicability was assessed by analyzing the usability evaluations provided by the officers. In response, there is a need to develop augmented reality core technologies, and the augmented reality navigational support technology proposed in this study is expected to prevent marine accidents and improve ship operational efficiency.
