Watercraft Display With Split Views for Safer Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Entry-level users operating watercraft experience anxiety due to limited visibility and understanding of their surroundings, leading to challenges in navigating safely.
Innovation Solution
An operation support system with a display that transitions between different views (oblique and top) and superimposes objects representing the watercraft's surroundings, obstacles, and operational information, adjusting display modes based on the watercraft's mode and positional relations with obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single view is displayed on the entire screen, then the display is simple and easy to understand, but the user has limited visibility of different angles of the watercraft surroundings
Solution Approach 1:
The display screen is segmented into multiple regions, with different views (first view and second view) displayed in different areas. This allows the user to see multiple angles of the watercraft surroundings simultaneously while maintaining a simple display interface that is easy to understand.
Solution Approach 2:
The system transitions from displaying a single two-dimensional view to displaying multiple views simultaneously by utilizing screen space in different areas. This dimensional approach to information presentation allows comprehensive visibility of surroundings without complicating the display interface.
2Loss of information
If multiple views are displayed simultaneously on the screen, then the user has comprehensive visibility of surroundings, but the display becomes complex and harder to understand
Solution Approach 1:
Different areas of the display screen are assigned different qualities and functions. The first area displays the first view while the second area displays the second view, allowing each region to serve its specific purpose. This local differentiation provides comprehensive visibility while maintaining clarity through organized presentation.
3Loss of information
If the display shows detailed information about obstacles and positional relations, then the user has better situational awareness, but the display becomes cluttered and less intuitive
Solution Approach 1:
The system creates simplified graphical representations (copies) of the watercraft and obstacles, displaying them in a standardized format that preserves essential positional and relational information while maintaining visual clarity. These graphical copies provide situational awareness without cluttering the display.

AI summary
An operation support system according to an embodiment including: a display mounted in a watercraft; and a display control unit causing a first view that is an image of the vicinity of the watercraft and/or a second view that is an image of the vicinity of the watercraft of an angle different from that of the first view to be displayed on the display, in which the display control unit causes a screen of the display to transition between a first screen and a second screen, the first screen is a screen in which the first view or the second view is displayed on the entire screen of the display, and the second screen is a screen in which the second view is displayed in a first area that is a partial area of the screen of the display, and the first view is displayed in a second area that is a remaining area of the screen of the display.
