Abstract
A series of field tests for evaluating feasibility and effectiveness of an integrated information display system for collision avoidance support (INT-NAV: Integrated Navigational Information System on Seascape Image) was carried out with a training ship "Taisei Maru". The INT-NAV provides functions for organizing information from RADAR, ARPA, AIS and seascape video image, for enhancing situation awareness of OOW (Officer of the Watch), and for supporting decision making of collision avoidance. The first is the tests for experienced OOWs to investigate how the INT-NAV is used and to get subjective evaluation of the INT-NAV based on the actual use of it. The second is the tests for novice mariners to get subjective evaluation based on experience of the INT-NAV expressed on a small simulator. The INT-NAV rated better than conventional way of displaying information in almost every item for the evaluation.
