Map Expression Data User Position Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map expression systems cannot display the position of another user on map expression data, which is limited to geographical regions represented by old maps, illustrated maps, sketch maps, and hand-written maps.
Innovation Solution
An information processing apparatus that stores map expression data associated with attribute values including region specifying information and position specifying information, allowing the transmission of position-added map expression data to show user positions on the map, with features like user registration, condition-based data transmission, and caching for efficient data display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If map expression data is stored with position specifying information for multiple users, then user position display capability is improved, but data storage complexity increases
Solution Approach 1:
The patent segments position information by creating separate storage structures: a position specifying information storage unit that stores position data for multiple users independently, and a map user information storage unit that associates specific users with map expression data. This segmentation allows the system to manage complex multi-user position data without overwhelming the overall system architecture.
Solution Approach 2:
The patent introduces an information processing apparatus as an intermediary between terminal apparatuses and map expression data. This intermediary acquires position specifying information from multiple users, associates it with appropriate map expression data, and transmits the combined information to terminal apparatuses. The intermediary manages the complexity by centralizing the association logic and data structure management.
2Adaptability or versatility
If position specifying information for multiple users is stored and transmitted, then user interaction capability is improved, but communication data volume increases
Solution Approach 1:
The patent merges position specifying information with map expression data into a unified data structure called map user information. By combining these elements, the system transmits integrated information packages rather than separate data streams, reducing overall communication overhead while maintaining full functionality for displaying multiple user positions on map expression data.
3Loss of information
If map expression data is transmitted with associated position specifying information, then information completeness is improved, but transmission time increases
Solution Approach 1:
The information processing apparatus performs preliminary actions by pre-acquiring and pre-associating position specifying information with map expression data before transmission requests are made. The system maintains ready-associated map user information in storage, so when a terminal apparatus requests map expression data, the complete information package is already prepared and can be transmitted immediately, reducing actual transmission time while maintaining information completeness.
Data Source
AI summary
An information processing apparatus includes: a map expression data storage unit in which two or more pieces of map expression data are stored; a position specifying information storage unit in which one or more pieces of position specifying information are stored in association with the map expression data; a request instruction receiving unit that receives a request instruction containing specifying information for specifying map expression data, from a terminal apparatus; a data acquiring unit that acquires map user information having map user information specified with the specifying information, and one or more pieces of position specifying information associated with the map user information; and a transmitting unit that transmits position added map expression data in which a position specified with the map user information, or the position specifying information contained in the map user information is shown on the map expression data, to the terminal apparatus.
