The JAN-9201/7201 incorporates a new user interface (named jGUI) for an intuitive, easy-to-use, simple menu system based on the display of icons. This interface always displays critical data in fixed positions on the screen while icon-based menu display informs users of corresponding functions straightaway. Furthermore, target tracking (TT) and AIS symbols feature pop-up displays while mouseover on the target showing their main data at a glance.
JRC’s new ECDIS model JAN-9201/7201 has integrated route editing, which was conventionally divided into two segments, i.e., graphics input and numeric table input areas, into one. Waypoints, if specified, on a navigational chart are immediately quantified and added to the numeric editing table, and the numeric data on the waypoints that is input into the editing table is immediately reflected on the navigational chart. Up to four routes can be edited at the same time, and a portion cut out of any route can be combined and the routes can be all or partly replaced or edited.
Furthermore, a safety check on edited route data is possible with a click of a button. Detected error information items, if any, are listed and displayed, and the corresponding route portions are highlighted in the chart and table, which can be confirmed at a glance to take remedial measures.
