Map Image Display Using Accessibility Priority From Current Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems display images based on distance and direction from the user's current position without considering accessibility, leading to images of less accessible places being shown, making it difficult to prioritize easily reachable locations.
Innovation Solution
An information processing device and method that acquires the present position of a movable object and displays images in a map based on accessibility priority, giving higher prominence to places easily reachable from the current position, using a terminal device with integrated display and navigation capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If posting-related images are displayed at positions corresponding to distance and direction from present position, then images of various facilities can be shown on the map, but images of less accessible places where user has already passed may be displayed
Solution Approach 1:
The patent changes the parameter basis for image display from simple distance and direction to accessibility priority. The display control unit calculates accessibility priority based on multiple factors including distance, direction, and user movement trajectory, then displays images in descending order of this priority metric, ensuring that easily accessible places are shown first while filtering out locations the user has already passed.
2Area of stationary object
If images are displayed regardless of accessibility as long as they are in a predetermined area, then complete area coverage is achieved, but it is difficult to display images according to accessibility from present position
Solution Approach 1:
The patent applies local quality by making different parts of the display area have different display priorities based on their accessibility characteristics. The display control unit evaluates each image location's accessibility independently and assigns different display priorities, ensuring that high-priority accessible locations are prominently displayed while low-priority inaccessible locations are suppressed, creating a non-uniform but optimized display distribution.
3Device complexity
If images are displayed based on distance and direction only, then simple display logic is used, but images of places that are far but in the same direction may be displayed alongside nearby places
Solution Approach 1:
The patent introduces accessibility priority as a new composite parameter that combines distance, direction, and user trajectory information. This single priority metric replaces the need for complex multi-factor decision logic, allowing the system to efficiently determine display order by simply sorting images according to their calculated accessibility priority values in descending order.

AI summary
An information processing device includes an acquiring unit that acquires a present position of a movable object, and a display control unit that displays an image posted in a manner associated with position information in a map of a predetermined area including the present position based on the present position and priority according to accessibility from the present position.
