Dynamic Lane Guidance Panel for Navigation Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face challenges in providing clear and intuitive lane guidance at complex road junctions, often leading to user confusion due to the use of static junction views combined with moving guidance views.
Innovation Solution
A navigation system that dynamically generates a lane guidance panel covering a portion of the navigation map, indicating the correct lanes to follow, which changes based on the user's approach to a junction, allowing simultaneous display of lane guidance and route continuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a static junction view is combined with a moving guidance view, then comprehensive navigation information is provided, but user confusion increases due to visual inconsistency
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a static junction view to a dynamic lane guidance panel that automatically updates based on the vehicle's approach to the junction. The panel is displayed only when needed (when the vehicle is approaching a junction) and hidden when not needed, creating a dynamic user interface that adapts to the navigation context. This resolves the contradiction by providing comprehensive information dynamically rather than statically, reducing user confusion while maintaining information completeness.
2Measurement precision
If lane guidance information is displayed prominently, then navigation accuracy improves, but visual clutter increases covering important map context
Solution Approach 1:
The patent applies segmentation by dividing the display into functional zones: the lane guidance panel occupies only the portion of the screen relevant to current navigation decisions (lane selection), while the rest of the map remains visible for context. The panel is segmented to show only essential lane information rather than redundant data. This resolves the contradiction by providing accurate lane guidance without overwhelming the user with excessive visual information.
Solution Approach 2:
The lane guidance panel is displayed dynamically only when the vehicle is approaching a junction where lane selection is needed. As the vehicle moves away from the junction, the panel is automatically hidden, restoring full map visibility. This dynamic display behavior ensures navigation accuracy is maintained when needed while preserving map context when lane guidance is not required.
3Loss of information
If a separate junction view is provided, then lane information is clear, but display complexity increases requiring users to switch between views
Solution Approach 1:
The patent merges the lane guidance information with the main navigation display by overlaying the lane guidance panel on top of the map view rather than requiring a separate full-screen junction view. The panel combines lane selection information with the contextual map background, allowing users to see both lane guidance and route continuation in a single integrated display. This resolves the contradiction by providing clear lane information without increasing display complexity or requiring view switching.
Data Source
AI summary
A method is disclosed for providing information using a navigation apparatus to guide a user in a vehicle along a determined route to a destination through a road network. The method comprises generating data indicative of a navigation map for display on a display device of a navigation apparatus showing the roads in a portion of the road network. The method further comprises generating data indicative of a first route line for display on the navigation map showing the one or more roads to be taken from a current position of the navigation apparatus to follow the determined route through the road network, and then providing the data indicative of the navigation map and the first route line to the display device for display thereon. The method further comprises generating, upon determining, while the vehicle is traveling along the determined route, that the current position of the navigation apparatus on a multi-lane roadway is approaching an associated road junction, data indicative of a lane guidance panel based on a position of the road junction in the navigation map that, when displayed on the display device, covers a portion of the navigation map. The method further comprises generating data indicative of a second route line for display at least on the lane guidance panel indicating one or more lanes in which the user should be travelling so as to follow the determined route, and then providing the data indicative of the lane guidance panel and the second route line to the display device for display thereon.
