Navigation Map Scrolling Icon Filtering for Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems face performance degradation and user confusion due to the overwhelming display of numerous POI and brand name icons during map scrolling, which hides important information like roads and intersections.
Innovation Solution
A method and apparatus for selectively displaying icons based on conditions and settings, removing generic POI icons during map scrolling while continuously showing brand name icons, and reviving icons in a simplified form during pauses or when necessary, to prioritize important information and reduce computational burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If numerous POI icons and brand name icons are displayed on the map image, then the user can see more information about businesses and points of interest, but the map scrolling performance deteriorates and important map elements become invisible
Solution Approach 1:
The patent extracts and removes generic POI icons from the map display during scrolling operations, while maintaining brand name icons and essential map elements. This selective extraction reduces the number of moving objects during scrolling, improving performance while preserving useful information through alternative display methods.
Solution Approach 2:
The patent segments icon display into different categories (generic POI icons vs. brand name icons) and applies different handling rules to each segment. Generic POI icons are removed during scrolling, while brand name icons continue to be displayed, allowing optimized performance without complete information loss.
2Loss of information
If generic POI icons are displayed during map scrolling, then users can see point of interest information, but the map elements such as roads and intersections become hidden
Solution Approach 1:
The patent extracts generic POI icons from the map display during scrolling operations, removing them to prevent obstruction of important map elements like roads and intersections. This extraction ensures clear visibility of navigation-critical elements while preserving brand name icons that provide useful information without blocking map views.
Solution Approach 2:
The patent applies different display qualities to different icon types: generic POI icons are hidden during scrolling to maintain map element visibility, while brand name icons remain visible to provide continuous information. This local differentiation optimizes both navigation clarity and information accessibility.
3Loss of information
If all icons are displayed continuously, then the navigation system provides complete information, but the computing power required increases significantly
Solution Approach 1:
The patent extracts generic POI icons from the rendering process during map scrolling operations, significantly reducing the number of objects the system must process and display. This extraction maintains essential information availability through brand name icons and alternative display methods while dramatically reducing computing power requirements.
Solution Approach 2:
The patent applies partial action by displaying only a subset of icons (brand name icons) during scrolling rather than all icons. This selective display provides sufficient information for navigation while consuming much less computing power than complete icon rendering would require.

AI summary
A map scrolling method and apparatus for a navigation system prevents from displaying certain icons while displaying other icons based on conditions and settings of the navigation system during a transition period of a map scrolling operation. The map scrolling method includes the steps of: detecting activation of a map scrolling operation; checking whether there is any limit condition attached to icons as to remove them from a map image; scrolling the map image while removing the icons to which the limit condition is attached from the map image during a transition period of the map scrolling operation; and displaying all of the icons when the map scrolling operation is completed.
