Map Display Reducing Landmark Sign Clutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map display apparatuses overwhelm users with numerous landmark signs, making important ones indistinct due to the inclusion of non-relevant signs, which hinders effective navigation and memory recall.
Innovation Solution
A map display apparatus and method that reduces the number of landmark signs displayed outside a predetermined range based on the image-pickup position, moving route, and current position, prioritizing important signs by type and location, using an image-pickup-position mark and landmark information storage to optimize landmark display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all landmark signs corresponding to selected types are displayed in the map image, then the completeness of landmark information is improved, but the distinguishability of important landmark signs deteriorates due to being buried in numerous non-important signs
Solution Approach 1:
The map display area is divided into multiple display regions based on distance from the current position (first display region for near landmarks, second display region for far landmarks). This segmentation allows different density levels of landmark signs to be displayed in different regions, preventing important nearby landmarks from being buried while still showing comprehensive information in distant regions.
Solution Approach 2:
Different display densities and types of landmark signs are applied to different spatial regions. The first display region (nearby) displays fewer, more selectively filtered landmark signs with higher visual prominence, while the second display region (distant) displays more landmark signs with lower visual prominence. This local differentiation ensures important landmarks stand out while maintaining overall information completeness.
2Manufacturing precision
If the number of landmark signs is reduced in ranges other than the first predetermined range, then the distinguishability of important landmark signs is improved, but the completeness of landmark information deteriorates
Solution Approach 1:
The display areas are segmented into first and second display regions based on distance thresholds from the current position. The first region (within threshold) displays selectively filtered landmarks with high distinguishability, while the second region (beyond threshold) displays additional landmarks to maintain information completeness. This segmentation resolves the contradiction by allocating different quantities of information to different spatial zones.
Solution Approach 2:
The solution adds a spatial dimension to information presentation by using multiple display regions at different distances. Instead of uniformly displaying all landmarks, the system creates a depth-based hierarchy where nearby important landmarks are prominently displayed in the first region, and additional contextual landmarks are displayed in the second region, maintaining completeness without compromising distinguishability.
3Ease of operation
If landmark signs are displayed similarly to conventional map display apparatus, then the simplicity of display control is maintained, but the effectiveness of navigation and memory recall deteriorates due to indistinctive important signs
Solution Approach 1:
The display control dynamically adjusts which landmark signs are displayed based on the user's current position and the defined display regions. As the user moves, the first and second display regions automatically update, causing the set of displayed landmarks to change dynamically. This dynamic adaptation improves navigation effectiveness without requiring complex manual control from the user.
Solution Approach 2:
The system automatically performs the complex task of filtering and prioritizing landmark signs based on spatial relationships with the current position. Instead of requiring users to manually select which landmarks to display, the system self-adjusts the display content by automatically categorizing landmarks into first and second display regions and applying appropriate filtering and prominence rules, thus maintaining ease of operation while improving reliability.

AI summary
In step ST11 of FIG. 5, a map image is displayed. In step ST12, moving-route marks are added to the map image. In step ST13, image-pickup-position marks are added to the map image. In step ST14, a current position mark is added to the map image. In step ST15, a predetermined range is determined based on an image-pickup position. Furthermore, predetermined ranges are determined based on a moving route and a current position. In step ST16, the number of types of landmark sign to be included in the map image is reduced in ranges other than the predetermined ranges. Since landmark signs which are positioned far from the image-pickup position, the moving route, and the current position and which are not important for a user are not added to the map image, map display is performed while display of the landmark signs is optimized.
