Map Display Control Program for Contextual Point Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current map display systems cannot simultaneously show a zoomed area and its positional relationship with the vicinity area, as zooming in hides point information from outside the zoomed area, requiring users to switch back to a primary map view, which limits the ability to view both the zoomed area and its context on the same screen.
Innovation Solution
The method displays the zoomed map area within the screen while indicating point information from the vicinity area in the periphery, using a map display control program that superposes excluded point information around the zoomed map area, allowing users to switch between normal and vicinity information display modes to maintain context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the map is zoomed in to display a specific area, then the detail of the zoomed area is improved, but the point information from the vicinity area is lost
Solution Approach 1:
The display screen is segmented into two functional zones: a central display area for the zoomed map and a peripheral display area for vicinity point information. This segmentation allows both the detailed zoomed view and the contextual vicinity information to be displayed simultaneously without interfering with each other, resolving the contradiction between achieving high detail and preserving contextual information.
Solution Approach 2:
The patent transitions from a single-dimensional full-screen map display to a two-dimensional layout that incorporates both zoomed area (central) and vicinity area (peripheral) information. By adding the peripheral dimension for context information, the system maintains detail while preventing information loss.
2Loss of information
If a divided screen is used to display multiple maps, then the positional relationship can be grasped, but the area of each displayed map is reduced
Solution Approach 1:
Different regions of the display screen are assigned different functional qualities: the central region provides high-detail map viewing while the peripheral region provides contextual information. This local differentiation allows the map area to remain large for detailed viewing while still providing necessary context, avoiding the uniform division problem.
Solution Approach 2:
The vicinity point information is extracted from the main map display and placed in the peripheral area. This extraction allows the main map display to maintain its full area for detailed viewing while the extracted information provides the necessary positional context separately.
3Measurement precision
If the user zooms in to view a specific area, then the detail view is improved, but the user cannot simultaneously view the zoomed map and its positional relationship with the vicinity area
Solution Approach 1:
The patent merges the detailed zoomed map view and the vicinity contextual information into a single integrated display interface. Users can simultaneously view both the detailed specific area and its positional relationship with the vicinity area without switching between different display modes, improving ease of operation.

AI summary
A map of a zoom area to be zoomed is displayed within a display screen while point information excluded from the zoom area is displayed in a position for indicating a direction thereof in a periphery of the map of the zoom area.
