Information Code Generation Adjusting Map Display for Destination Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information codes integrated with map images fail to effectively convey the destination position to users, especially those unfamiliar with the geography, as the destination position may not be clearly recognizable due to inadequate representation on the map.
Innovation Solution
An information code generation apparatus and program that adjust the center position and/or display scale of a map image based on environment information, such as POI and terrain data, to set a display range that clearly indicates the destination position, allowing users to visually grasp the location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the destination position is set at the center of the map image, then the destination position is clearly indicated, but users geographically unfamiliar with the destination may fail to recognize the geography in the vicinity
Solution Approach 1:
The patent applies local quality by adjusting the map display parameters (center position and display scale) based on the specific geographic characteristics of the destination area. Instead of using a fixed centering method, the system dynamically modifies the map presentation to highlight locally important geographic features that help users understand the destination context, thereby resolving the contradiction between precise destination indication and geographical comprehensibility.
2Device complexity
If a map image with a fixed display range is used, then the information code structure is simple, but the destination position may not be easily understood by users
Solution Approach 1:
The patent implements dynamics by making the map image display parameters adaptive rather than fixed. The center position and display scale are dynamically adjusted based on environment information about the destination, allowing the map to automatically optimize its presentation for different locations. This dynamic adjustment maintains relatively simple code structure while significantly improving destination understandability.
3Manufacturing precision
If the display scale of the map image is increased to show more detail, then geographic features become clearer, but the overall destination position may become less prominent
Solution Approach 1:
The patent applies parameter changes by systematically adjusting both the center position and display scale parameters of the map image based on destination characteristics. Rather than fixing one parameter, the system coordinates changes in multiple parameters to achieve an optimal balance where geographic details are sufficiently clear while the destination position remains prominently displayed, resolving the contradiction between detail visibility and destination prominence.

AI summary
An information code generation apparatus includes: a setting unit that specifies a destination position based on position specifying information included in coding information for generating an information code, wherein the setting unit acquires, from a database, environment information indicating information on a peripheral environment of the specified destination position, and sets a display range of a map image to be displayed by adjusting at least one of a center position or a display scale based on the destination position and the acquired environment information; and an information code generation unit that acquires, from the database, the map image having the display range set by the setting unit, and generates the information code by integrating the map image with the information code.
