Maneuver Indicators on Map for Complex Route Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mapping applications do not provide sufficient visual information about maneuvers, making it inconvenient for users to navigate through complex routes with multiple roads and intersections.
Innovation Solution
A mapping application that displays maneuver indicators, such as arrows, at the location of each maneuver along the route, accompanied by instructional banners providing textual and pictorial guidance, allowing users to easily understand and follow directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If maneuver indicators are displayed along the entire route, then users have continuous navigation guidance, but the visual interface becomes cluttered and harder to interpret in congested areas
Solution Approach 1:
The patent divides the route into segments and displays maneuver indicators only at specific locations where maneuvers occur, rather than continuously along the entire route. This segmentation approach provides necessary navigation information at key decision points while avoiding visual clutter in congested areas with multiple roads and intersections.
Solution Approach 2:
The patent applies different display qualities to different parts of the route by highlighting maneuver indicators at specific locations with visual emphasis (such as color changes or size adjustments) while keeping other parts of the route less prominent. This local quality enhancement helps users focus on upcoming maneuvers without being overwhelmed by the entire route visualization.
2Loss of information
If multiple maneuver indicators are displayed simultaneously in congested areas, then users receive complete maneuver information, but users become confused about which maneuver to perform next
Solution Approach 1:
The patent implements dynamic highlighting of maneuver indicators based on the user's current position and the sequence of maneuvers. As the user progresses along the route, the system dynamically updates which maneuver indicator is highlighted, ensuring that only the relevant next maneuver is prominently displayed. This dynamic approach maintains ease of operation by guiding users through maneuvers in the correct sequence while still providing access to complete maneuver information.
Solution Approach 2:
The patent displays maneuver indicators in advance along the route, allowing users to see upcoming maneuvers before reaching them. By presenting this information preliminarily and organizing it in the sequence of execution, users can mentally prepare for the series of maneuvers needed in congested areas without being overwhelmed by simultaneous presentation of all maneuvers.
3Loss of information
If maneuver indicators are displayed at all zoom levels, then users have maneuver information available in all views, but the indicators become too small to see at high zoom levels
Solution Approach 1:
The patent adjusts the display parameters of maneuver indicators based on the zoom level. At different zoom levels, the system changes parameters such as indicator size, spacing, and perhaps even the level of detail shown. This ensures that maneuver information remains visible and interpretable across all zoom levels, with indicators being large enough to see at high zoom levels while still providing comprehensive information at lower zoom levels.

AI summary
For a device that runs a mapping application, a method for providing maneuver indicators along a route of a map. The maneuver indicators are arrows that identify the direction and orientation of a maneuver. A maneuver arrow may be selected and displayed differently from unselected maneuver arrows. Maneuver arrows may be selected automatically based on a user's current location. The mapping application transitions between maneuver arrows and provides an animation for the transition. Complex maneuvers may be indicated by multiple arrows, providing a more detailed guidance for a user of the mapping application.
