Map View Designation Display Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional map views on mobile devices cause points of interest designations to appear and disappear as users zoom in or out, leading to an inconsistent user experience due to algorithms that prioritize ranking information without considering interference between designations.
Innovation Solution
A map tool that determines a set of points of interest to display based on ranking data and hierarchical levels, ensuring that designations do not interfere with higher-ranked points, even in expanded or augmented map views, and maintains consistent display across varying zoom levels by reserving space for higher-ranked points of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional algorithms select designations based only on ranking information within current map view, then more points of interest can be displayed, but designations appear and disappear as user zooms in or out
Solution Approach 1:
The system performs preliminary actions by determining a set of points of interest to display based on both current and expanded map views before the user actually zooms. By anticipating future zoom levels and pre-determining which designations should remain visible, the system prevents the appearance and disappearance of designations during user interaction, thus maintaining display consistency while showing multiple points of interest.
2Loss of information
If designations are displayed for multiple points of interest, then more information is provided, but the map view becomes cluttered and less clear
Solution Approach 1:
The system applies local quality by selectively displaying designations based on their importance and the specific map view context. Rather than uniformly displaying all points of interest, the system determines which designations to show in each local area of the map view, prioritizing higher-ranked points of interest and adjusting display based on the expanded map view to maintain clarity while providing comprehensive information.
3Measurement precision
If algorithms prioritize ranking information for selecting designations, then important points of interest are highlighted, but lower-ranked points may be overlooked or cause interference
Solution Approach 1:
The system adds another dimension to the selection process by considering not only the current map view but also an expanded map view that encompasses future zoom levels. This dimensional expansion allows the system to maintain ranking accuracy for important points of interest while also ensuring that lower-ranked points remain visible and do not cause interference as the user zooms, thus improving display adaptability across multiple zoom levels.

AI summary
Methods and apparatus for a map tool for determining which points of interest in a map region for which to display designations or labels in a map view such that a displayed designation does not disappear and reappear as a user zooms in or out of a map view or as a user pans across a map region. Also disclosed are methods and apparatus for a ranking tool that uses a hierarchy of categories in order to classify points of interest, where for each given hierarchical category, the points of interest within the given hierarchical category are further ranked according to ranking data for each given point of interest and also ranked according to the quantity of the ranking data for the given point of interest.
