Outing History Matching for Reliable Destination Encounters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information sharing technologies fail to account for changes in user schedules, leading to reduced motivation for interactions among users heading to a common destination, particularly affecting elderly individuals living alone.
Innovation Solution
An information processing device that acquires outing histories of multiple users, determines encounter situations, and transmits relevant information only when users have actually met, ensuring timely and relevant interaction opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is provided to users before they encounter each other at a destination, then users can be informed of potential interactions in advance, but users may lose motivation to head for the destination if their schedules change
Solution Approach 1:
The system performs preliminary matching of users based on destination and timing information before they actually meet. The server determines that users are likely to encounter each other by comparing destination information and timing information in advance, and provides notification information to motivate users to head for the destination before the actual encounter occurs.
Solution Approach 2:
The system uses feedback from user responses to notification information. When the server receives a response indicating a user will head for the destination, it confirms the interaction opportunity and provides more accurate timing information. This feedback mechanism allows the system to adapt to schedule changes and maintain reliability.
2Loss of time
If information is provided too early before users meet, then users have time to prepare, but the information may become outdated if user schedules change
Solution Approach 1:
The system performs periodic updates of user information by receiving updated destination and timing information from users' terminals. The server repeatedly determines whether users are still likely to encounter each other and re-transmits notification information as needed, ensuring information remains current while providing ongoing preparation time for users.
3Productivity
If the system provides information to all users with common destinations, then more interaction opportunities are created, but unnecessary information is transmitted to users who will not actually meet
Solution Approach 1:
The system applies different processing to different users based on their specific characteristics. The server determines whether each user is likely to encounter others by analyzing individual destination and timing information, and selectively provides notification information only to users who meet the likelihood criteria, avoiding unnecessary transmissions.

AI summary
An information processing device includes a history information acquisition unit which acquires outing histories of a plurality of third users specified based on first address information registered in a first transmission device, and second address information registered in a second transmission device; a destination determination unit which determines a reception device owned by a third user satisfying a specification condition as a destination of at least one of first specification information including first position information indicating a position of the first transmission device, and second specification information including second position information indicating a position of the second transmission device; and an information transmission unit which transmits at least one of the first and second specification information to the reception device determined as the destination.
