Content Output Controller for Map Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content output systems that display information related to a user's position on a map can be inconvenient for users, especially when excessive information is displayed at once, making it difficult for users to recognize relevant details, particularly in situations like vehicle operation, where user interaction is challenging.
Innovation Solution
A content output system that includes an output unit, a user state recognizing unit, a content recognizing unit, and a content output controller to selectively output supplementary information and content based on the user's movement mode and positional relationship with the content, allowing users to recognize content without overwhelming them with excessive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed information on post information is displayed together with post icon on map, then user can recognize detailed information, but it becomes difficult for user to recognize each piece of information and gives inconvenience to user
Solution Approach 1:
The patent divides information display into two stages: first displaying only post icons on the map, then displaying detailed information separately when the vehicle approaches within a predetermined distance. This segmentation prevents information overload while ensuring users can recognize details when relevant, resolving the contradiction between information accessibility and user convenience.
Solution Approach 2:
The system performs preliminary display of post icons before the vehicle reaches the posting position, allowing users to see what content is available in advance. When the vehicle approaches within the predetermined distance, detailed information is then displayed. This preliminary action helps users plan their information consumption and avoids sudden information overload.
2Ease of operation
If post information is displayed only after vehicle distance becomes within predetermined distance, then user convenience is improved, but user may be dissatisfied if information differs from expectation
Solution Approach 1:
The patent segments information display into two phases: first showing post icons on the map to provide overview and manage expectations, then displaying detailed information when the vehicle is close. This ensures users see both the overview (satisfying expectations) and detailed information (providing convenience), resolving the contradiction between early information display and user convenience.
3Loss of information
If enormous amount of detailed information is displayed on map, then complete information is provided, but user cannot recognize detailed information on each piece of content
Solution Approach 1:
The patent segments the display of detailed information by triggering it only when the vehicle is within a predetermined distance from the posting position. At this point, the system displays detailed information in a separate output (not cluttering the map), allowing users to recognize each piece of information clearly while still receiving complete information when relevant.
Solution Approach 2:
The patent moves detailed information display from the two-dimensional map interface to a separate output dimension (such as a dedicated display area or audio output). This dimensional separation allows complete information to be provided without cluttering the map interface, maintaining both information completeness and recognizability.

AI summary
An information output system is provided which allows a user to recognize information appropriately while reducing or eliminating inconvenience given to the user. A content output system includes a content output controller 213 which selects output candidate content on the basis of the movement mode of the user and the content position, causes an output unit 25 to output supplementary information on the output candidate content when the relative positional relationship between the user and the output candidate content satisfies a predetermined first condition, and causes the output unit 25 to output the output candidate content when the relative positional relationship between the user and the output candidate content satisfies a predetermined second condition.
