Abstract

An INS is a composite navigation system providing "added value" so defined if work stations provide Multi-Function Displays(MFDs) integrating information and functions for navigational tasks. Even though the minimum requirements for an INS are defined by IMO performance standards, a generic list of the devices and functions that constitute an INS does not exist, so the configuration of the INS is different for each manufacturer, and guidelines based on users' perspectives are also insufficient. This study was conducted to enhance the usability of the INS by analyzing the information required by users according to the ship's operating status and tasks and effectively structuring it in the MFD of the INS. By analyzing INS-related international standards and manufacturers' component equipment lists, mandatory navigation information was selected and card sorting tests were conducted on ship operators with experience in using MFDs to group the information required for each INS task. The results of the study can serve as a basic guideline for manufacturers to structure information based on users' experience when designing products.

통합항해시스템(INS)은 기존 항해 장비들을 통합하여 부가가치를 제공하는 장치로써 항해 업무 수행을 위한 정보와 기능을 다기능표시장치에(MFD)에 통합하는 것으로 정의된다. IMO 성능 기준은 각 업무에 대한 최소 요구사항을 명시하고 있지만, 장비 및 기능의 목록은 정의하지 않아 제조사마다 INS의 구성이 상이하고 사용자 관점에 기반 한 지침 또한 부족한 실정이다. 본 연구는 선박 운용상황 및 수행 업무에 따라 사용자가 요구하는 정보를 분석하고, 이를 INS의 MFD에 효과적으로 구조화하여 INS의 사용성을 높이기 위해 수행되었다. INS 관련 국제 기준 및 제조사의 구성 장비 목록을 분석하여 필수 항해 정보들을 선별하고 MFD 사용 경험이 있는 선박 운항자를 대상으로 카드 소팅 테스트를 실시하여 각 INS 업무에 요구되는 정보들을 분류하도록 하였다. 연구의 결과는 제조사들이 제품 설계 시 사용자 경험을 반영한 정보 구성에 기본적인 가이드로 활용될 수 있을 것이다.
