Map Display Window Segmentation for Context Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems and display devices struggle to allow users to easily enlarge or change the display range of map objects without losing the relationship between displayed and non-displayed regions, making it difficult to understand the overall layout and details.
Innovation Solution
A display processing device that divides the display window into sections, allowing users to move boundaries and adjust display scales within these sections, enabling easy enlargement of the display range while maintaining the relationship between displayed and non-displayed areas through section-based display range and scale adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the map is displayed such that the scale is increased the closer the vehicle is to one or more particular points, then the map around particular points can be displayed in detail, but when the user scrolls or enlarges a region, a part of the previously displayed map is no longer displayed, making it difficult to understand the relationship between displayed and non-displayed regions
Solution Approach 1:
The display window is divided into multiple sections with boundaries between them. When a user operates on a boundary, the system segments the display range adjustment by section, allowing different sections to have different display scales and ranges independently. This segmentation enables detailed viewing in one section while maintaining context in other sections.
Solution Approach 2:
The system adds a section dimension to the traditional single display window. By dividing the display window into sections and allowing independent scale and range adjustments for each section, the system creates an additional organizational dimension that preserves both detailed and contextual information simultaneously.
2Adaptability or versatility
If the user scrolls the map to confirm a region around the area currently displayed, then the user can view additional regions, but the previously displayed map portion is no longer displayed, requiring troublesome operations to re-display it
Solution Approach 1:
The display boundaries between sections are made dynamic and movable. Users can directly operate on boundaries to adjust display ranges of adjacent sections, creating a flexible system where the display configuration adapts to user needs without complex operations. The boundary itself becomes the control interface for range adjustment.
Solution Approach 2:
The system allows users to self-adjust display ranges by simply operating on boundaries. The boundary operation automatically triggers the appropriate display range changes in adjacent sections, eliminating the need for separate scroll or re-display operations. The system serves itself by using the boundary as both the control element and the reference for adjustment.
3Measurement precision
If the user enlarges a region to confirm details, then detailed information becomes visible, but the overall layout context is lost, making it difficult to understand the relationship between the enlarged region and the rest of the map
Solution Approach 1:
The display window is segmented into multiple sections, allowing one section to be enlarged for detailed viewing while other sections maintain the overall layout context. The segmentation enables simultaneous display of different scales and ranges in different parts of the window, preserving both detail and context.
Solution Approach 2:
Different sections of the display window can have different display qualities, specifically different scales and ranges. The section where the user wants detailed information can be enlarged, while other sections maintain their original scale to preserve the overall layout relationship. Each section has locally optimized display properties.

AI summary
A display processing device for displaying a display object in a display window and changing a display range includes a sectioning unit that divides the display window into a plurality of sections (screens) by creating boundary lines. Maps of geographical ranges to be displayed are sectioned and displayed in the plurality of screens. In the event that a boundary line is moved through a user input, the geographical ranges of the maps in the screens for which the screen size has become larger than an initial screen size are enlarged, and the maps in the screens which have become smaller than the initial screen size are reduced in scale in accordance with the reduction in screen size, while maintaining the geographical range of the maps displayed in the display window prior to the boundary line being moved.
