Ship Display Device Using Segmented Icons for Target Bearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ship display devices fail to provide an intuitive understanding of multiple targets around a host vessel, making it difficult for users to grasp the situation effectively.
Innovation Solution
A ship display device comprising an information acquisition component, an icon generator, and a display component that generates icons representing the relative bearing and heading of the host vessel and other targets, along with collision risk, allowing users to intuitively understand the positional and directional relationships between vessels.

Engineering Contradiction Analysis
1Ease of operation
If multiple other targets are displayed on the screen, then the overall situation can be ascertained, but it becomes difficult to grasp each individual target intuitively
Solution Approach 1:
The display is segmented into multiple icon regions, with each region dedicated to displaying information about a specific other target. This segmentation allows the user to view multiple targets simultaneously while maintaining clear, intuitive understanding of each individual target's bearing and position relative to the host vessel.
2Ease of operation
If detailed information about each target is displayed, then each target can be understood, but the overall situation becomes complicated
Solution Approach 1:
Multiple pieces of information about each target (bearing, position, and visual representation) are merged into a single integrated icon. This merging allows detailed target information to be displayed in an organized, compact format that does not complicate the overall display, enabling users to understand each target while maintaining a clear overview of the situation.

AI summary
An AIS information display device comprises an information acquisition component, an icon generator, and a display component. The information acquisition component acquires bearing information, which is information about the bearing of other targets with respect to the position of the host vessel. The icon generator uses an icon-use host vessel symbol S3 and one other target symbol S2 to generate an icon 19 that indicates the relative bearings of the host vessel and another target. The display component displays the icon 19 generated by the icon generator. Consequently, a ship display device can be provided which makes every target easy to understand, even when there are many other targets around the host vessel.
