Map Display Icon Type Control During Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map display systems frequently change the type of icons displayed when the user's location changes, causing user annoyance due to frequent switching between normal and simple landmarks.
Innovation Solution
A map display system and program that select the type of icons based on the number of icons displayed on the map, with a control mechanism to prohibit changes in icon types during map scrolling, ensuring consistent icon types before and after scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the type of icons is switched based on the number of icons displayed when the user's location changes, then the map display adapts to different locations, but the icon type changes frequently causing user annoyance
Solution Approach 1:
The system determines the icon type in advance based on the initial number of icons calculated from the map display range and icon interval, before the user scrolls the map. This preliminary determination prevents frequent icon type changes during scrolling operations, resolving the contradiction between adaptability and user experience.
2Reliability
If the icon type changes with each location change, then the map display reflects current location context, but the frequent switching causes annoyance
Solution Approach 1:
The icon type is determined in advance based on the map display range and icon interval before scrolling occurs. This preliminary determination ensures the icon type reflects the location context while preventing frequent changes during user interaction, thus maintaining reliability without causing user frustration.
3Loss of information
If normal landmarks are displayed in predetermined regions, then detailed information is provided, but simple landmarks should be shown outside predetermined regions
Solution Approach 1:
The system applies different icon types (normal or simple landmarks) to different regions based on the calculated number of icons. By determining icon type locally for each display region based on icon density, the system provides appropriate information detail while managing display complexity through automated regional classification.

AI summary
There is provided a technique for reducing the frequency of a user feeling annoyed. A map display system includes: a map display part that displays a map on a display; an icon display control part that selects a type of icons to be displayed from among a plurality of types based on a number of the icons displayed on the map, and displays ground objects by the icons of the selected type on the map; and an icon selection control part that allows or prohibits a change in the type of icons selected by the icon display control part, and prohibits, when scrolling of the map is performed, a change in the type of icons before and after the scrolling.
