Marine Navigation UI for Priority-Based Path Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine navigation systems lack intuitive user interfaces that allow users to prioritize and adjust navigation paths based on their preferences, such as energy efficiency, time to target, or obstacle clearance, due to the unconstrained nature of marine navigation and the complexity of vessel movement.
Innovation Solution
A user interface system that allows users to input selectable priorities for path planning, which the control system uses to define a prioritized navigation pathway, considering factors like acceleration limits, obstacle distance, travel time, and energy efficiency, and prompts users to confirm or adjust the pathway before autonomous or semi-autonomous navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If marine navigation systems provide unconstrained navigation freedom, then vessel maneuverability is improved, but user interface complexity and path planning difficulty increase
Solution Approach 1:
The navigation path planning is segmented into multiple candidate paths generated by the system, allowing the user to select from discrete options rather than managing continuous navigation parameters. This reduces the cognitive load and interface complexity while preserving maneuverability through the generated path options.
Solution Approach 2:
The system acts as an intermediary between the user's navigation goals and the complex marine environment. It automatically generates and evaluates multiple path options based on user-selected priorities, mediating the complexity of unconstrained navigation by presenting simplified path choices to the user.
2Adaptability or versatility
If the system generates multiple path options, then user preference satisfaction is improved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary action by pre-generating multiple candidate navigation paths based on user-selected priorities before the user needs to make a decision. This allows the paths to be ready for immediate selection, reducing the time loss during actual navigation decisions while providing comprehensive path options.
3Manufacturing precision
If the system provides detailed path planning controls, then navigation precision is improved, but ease of operation decreases
Solution Approach 1:
The system performs self-service by automatically generating and optimizing multiple navigation paths based on user-selected priorities without requiring detailed manual control input. The user simply selects their preferences and the system handles the complex path planning computations, maintaining high precision while improving ease of operation.

AI summary
A method of controlling navigation for a marine vessel includes receiving a user input via a user input device identifying at least one selectable priority for path planning, defining a prioritized navigation pathway through a marine navigation area based on the at least one selectable priority for path planning indicated by the user input between a vessel location and a navigation target location, generating a display image representing the marine navigation area and the prioritized navigation pathway, and displaying the display image on a display device.
