Optimizing ECDIS as an Information Resource for Ocean Navigation

Ship electronic chart display and information systems have become critical information resources in ocean navigation; however, their effectiveness has been frequently undermined by data overload, delayed responses, and poor interface design. This study treated ship electronic chart display and information systems as a managed information resource needing to be aligned with operational demands and human cognitive capacity—not just a technical tool. The study proposed a lightweight, three-layer optimization approach based on adaptive data loading, predictive risk awareness, and cognitive load-aware display. This approach improved decision support without hardware upgrades. Validated through real automatic identification systems (AIS) trajectories and crew eye-tracking, the framework enhanced situational awareness and reduced operator stress in high-traffic voyages. The findings offer practical guidance for maritime organizations regarding better management of onboard information systems to improve safety and operational efficiency.
