According to a report from the Japan Marine Accident Inquiry Agency, major causes of ships' collision were navigator's human error such as improper lookout, non-compliance with navigation rules, etc. Moreover there are many collisions due to fault predictions of encountered ship's maneuver because of arbitrary assumption of encountered ship's behavior. It shows that the gap between the predicted action and actual action may cause collisions. To reduce collisions, it is important that effective communication between encountered ships and the way for confirming both ships' intention are expected to reduce the gap. To clear the uncertainty of encountered ship's maneuvers, we started a research on navigational intention exchange support system (NIESS) by using AIS binary message. In 2007 we carried out a usability study to confirm basic functions of the NIESS by using a desktop simulator. Through the study, we confirmed the adequate usability of the basic functions of the NIESS and usefulness for decision making for collision avoidance. As the next step, we carried out a simulator study to confirm the applicability of the NIESS in actual watch-keeping operation by using a full mission ship handling simulator. Results of the simulator study show that the NIESS operations are easy enough for watch keeping operation and they are rated effective for exchanging navigational intension by examinees of simulator study.
