In 2019, the International Maritime Organization (IMO) prescribed guidelines to standardize the user interface (UI) of navigation equipment such as radio detection and ranging (RADAR) and the electronic chart display and information system (ECDIS), which mandate the unification of various terminologies and icons to improve usability. However, comprehensive studies on the operability and standardization of global positioning system (GPS) plotters, which are auxiliary equipment installed across various domestic and commercial vessels for navigational purposes, have not been conducted. Therefore, we performed a case study to identify the user requirements for standardizing the UI of GPS plotters in South Korea. Additionally, we conducted a survey to ascertain the frequency of use of the navigational functions in a GPS plotter, in which, several deck officers and captains participated. The frequently used navigational functions that were subsequently identified confirmed the need for standardization of the UI. Furthermore, the users requested the standardization of the menus of these functions using Korean terminologies. Hence, we attempted to derive standardized items that can be applied to both the functions of the GPS plotters and the navigation information obtained, which can contribute to the improvement of the UI across the different types of plotters.

GPS绘图仪用户界面增强可用性的案例研究

2019年，国际海事组织（IMO）制定了准则，以标准化导航设备的用户界面（UI），例如无线电检测和测距（RADAR）以及电子海图显示和信息系统（ECDIS），这要求统一各种改善可用性的术语和图标。但是，尚未对全球定位系统（GPS）绘图仪的可操作性和标准化进行全面研究，这些绘图仪是为航行目的而安装在各种家用和商用船舶上的辅助设备。因此，我们进行了一个案例研究，以识别标准化韩国GPS绘图仪用户界面的用户需求。此外，我们进行了一项调查，以确定GPS绘图仪中导航功能的使用频率，其中，几个甲板官兵和船长参加了。随后确定的常用导航功能证实了需要对UI进行标准化。此外，用户要求使用韩语术语对这些功能的菜单进行标准化。因此，我们尝试得出可同时应用于GPS绘图仪功能和所获得的导航信息的标准化项目，这可有助于改善不同类型绘图仪的UI。
