Mobile Terminal Map Display for User Post Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile navigation systems struggle to efficiently display and update user-provided information on maps, as they are limited to facility evaluations and cannot handle information not associated with map data, and lack flexibility in displaying voluntary user information.
Innovation Solution
A mobile information terminal and information management device system that associates location information with post information, allowing flexible display of user-provided information on maps through wireless communication, enabling real-time updates and integration of information from various sources, including other mobile terminals and public networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses facility-information delivery to send questionnaire answers, then user evaluation contents can be renewed to the latest state, but the information is limited to facility evaluations and cannot handle user-provided information not associated with map data
Solution Approach 1:
The system extends the information delivery mechanism from solely facility evaluations to handle any user-provided information. The mobile information terminal can now receive and display various types of information (traffic conditions, events, weather, etc.) from both the information management device and other mobile terminals, making the system versatile and adaptable to different information types while maintaining the ability to renew information to the latest state.
2Loss of information
If the system associates information only with facilities in map information, then facility evaluation can be displayed, but information concerning facilities not included in map information cannot be delivered
Solution Approach 1:
The system introduces location information as an intermediary element that bridges the gap between map data and user-provided information. Instead of directly associating information only with facilities, the system uses location information to connect and deliver various types of information (facility data, traffic conditions, events, etc.) to the mobile information terminal, enabling complete information delivery without significantly increasing system complexity.
3Adaptability or versatility
If the system displays user-provided information on map locations, then information flexibility is improved, but the system cannot handle information without location association
Solution Approach 1:
The system dynamically adapts its information display capabilities based on the availability of location information. When location information is associated with user-provided information, the system displays it on the map at the corresponding location. When location information is not available, the system alternative displays the information through other means (such as list views or pop-up panels), maintaining display flexibility while ensuring information usability in all scenarios.

AI summary
Provided are a mobile information terminal, an information management device, and an information management system for mobile information terminals comprising the mobile information terminal and the information management device, with which it is possible to flexibly display also information that is voluntarily provided, for example, by a user, on map information. A navigation system of a vehicle acquires, by wireless communication, location information and post information that has been posted together with the location information, from an information management device of a management center in a state where the location information and the post information are associated. The navigation system controls the display of the acquired post information by a display device to be displayed in superposition in a location that is displayed upon the map information by the acquired location information.
