According to the development of technology of the navigational equipments, many bridge equipments have been improved, however, marine accidents by human error have not been reduced. Therefore, a matter of primary concern is focused on whether bridge equipments of ships are ergonomically arranged to reduce errors due to human factors. As part of a design of IBS(Integrated Bridge System) standard, rules of the conning display to save time and additional movements to obtain important informations of a ship should be established as soon as possible. In the present study, ergonomic design factors for the conning display are studied through the survey of related works, heuristic evaluations, sketch method tests as well as questionnaires. Using these factors, new conning display was designed and the ergonomic indices were evaluated by comparing tests of the existing conning displays. It is found that the designed conning display obtained high ergonomic index showed better performance, therefore, the ergonomic index studied in the present paper can be used as a useful design standard in the conning display design procedures.

In many fields, commercial programs or equipments are biting developed and these are getting complicated more and more by adding advantages from existing products. In promoting the usability of these products, design based on the information integration receives attention. However, is information integration always better? In this study, we tried to demonstrate information distribution is more efficient than information integration through conning display design that was propelled by many countries' classification societies. We designed the conning display using many ergonomic methods and conducted its performance experiment. Results of the performance experiment reveal that conning display having two modes (one shows the functions related with ocean and coast voyage and another shows the functions related with docking and leaving port) is more efficient.

The conning display which is located in the ship bridge shows the various important information such as ship position, ship speed, track data, rate of turn, thruster rpm so on, and is one of the IBSs(Integrated Bridge Systems). In this study, the survey was conducted for ten officers to find the importance and using frequency of the information which were displayed in the conning display. The results showed that the information of drift speed, ship speed, wind direction and wind force, rate of turn, sea water depth, ship position, heading, thrust rpm, alarm, rudder command and angle got high scores and it meant that these information were very important and high frequency of use during the navigation. The optimized contents arrangement in conning display was suggested based on importance and using frequency of information. The experiment using eye-tracking system was conducted to compare the performance time and error rate of nine different scenarios for suggested arrangement display and three other existing displays. The results showed that the suggested arrangement was the best in performance time and error rate. The scenario concerning the direction and speed of wind showed faster performance time and lower error rate than other scenarios. The movement of subject's eye tended to search from the center and to avoid the comer, called 'the comer effect.' It is expected that the results of this study could help for the bridge staff to grasp the sailing information easily and to cope with the given situations promptly.

현재 선박에서는 선상정보체계의 디지털화 추세가 가속화되어 고성능의 통합형 선방용 컴퓨터를 필요로 하며, 현재도 그 납품 실적이 꾸준히 증가하는 추세이다. 하지만 실제 선박 내의 운용환경을 충분히 고려한 선박용 컴퓨터의 개발은 그 실적이 부진한 실태로, 잦은 고장과 합리적이지 못한 인터페이스 장치들의 적재로 원활한 운용환경을 제공하지 못하고 있다. 그리하여 기초설계부터 특수한 해양환경에 적합하도록 고안되고, 선박의 통신체계(NMEA 0183)를 완벽히 지원하여 항해보조장치로서의 임무를 충실히 소화해 낼 수 있는 선박용 컴퓨터 개발을 필요로 하게 되었다.

Berthing and unberthing maneuver is essential work for marine pilots and securing the safety against risks during the maneuver is more important than anything else. Moreover, the maneuvering environment in ports and harbors has changed rapidly and got worse due to development of a new port, the advent of a new type or large-sized ship, and the rapid increase in harbor traffic. As one of measures taken to cope with such changes in the maneuvering environment and for each pilot to improve his own maneuvering ability, this paper developed laptop-based ship-handling simulator which is readily available anytime and anywhere. This paper is to develop a conning display for ship's maneuvering and electronic chart based display widely used nowadays to represent a model ship's movement. The displays were arranged appropriately considering pilot age, easy handling by mouse, using a maximum screen, proper arrangement of rudder, engine, thruster, tug etc and representation of information. Up to now thirteen (13) model ships were developed based on real-ship, whose mathematical model is Japanese MMG & pilots' low speed maneuver.
