Personalized Place Name Recording for Action History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional action history recording technologies are limited in obtaining and recording place names relevant to users, as they only record names from general-purpose maps and fail to provide personalized and convenient place names, making the recorded history less useful for personal diaries.
Innovation Solution
An action-history recording apparatus that includes a position detecting unit, a converting unit, and a judging unit to determine if the detected position matches stored data, allowing for the conversion of position data into personalized place names, which can be user-defined or obtained from a network, enabling the recording of specific and frequently visited places with appropriate names.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional general-purpose map place names are used for recording action history, then the recording system is simple and easy to implement, but the recorded history lacks personalization and convenience for users
Solution Approach 1:
The system performs preliminary actions by storing multiple candidate place names and their associated position data in advance. When converting current position data, the system checks against pre-stored position data to find matches, thereby achieving personalized place names without complex real-time processing.
Solution Approach 2:
The system creates copies of place name information from multiple sources (general-purpose maps, user-defined names, frequently visited places) and stores them in a database. This allows the system to select appropriate place names without complex real-time conversion, reducing system complexity while maintaining personalization.
2Loss of information
If position data is converted to place names using general-purpose maps only, then the conversion process is simple, but the recorded place names do not reflect user-specific important locations
Solution Approach 1:
The system applies different quality standards to different place names: general-purpose map place names for common locations, user-defined place names for personally important locations, and frequently visited place names for regular destinations. This local differentiation preserves personal information while maintaining efficient conversion through targeted matching.
Solution Approach 2:
The system incorporates user feedback by allowing users to define their own place names for specific positions and by learning frequently visited places from usage patterns. This feedback mechanism ensures personal place information is retained and reflected in future conversions without requiring complex manual input each time.
3Measurement precision
If the system records detailed position data for all locations, then accuracy of location tracking is improved, but the amount of data to be processed and stored increases significantly
Solution Approach 1:
The system extracts only the essential position data (latitude and longitude) needed for matching with pre-stored location information, rather than processing and storing all possible position attributes. This extraction approach maintains location tracking accuracy while significantly reducing the volume of data to be processed and stored.
Solution Approach 2:
The system performs preliminary matching of current position data against pre-stored position data before recording. By checking whether the current position matches any stored position data, the system avoids redundant storage of duplicate location information, thereby reducing data volume while maintaining accurate location tracking.

AI summary
With use of GPS, an action-history recording apparatus obtains latitudes and longitudes representing places of user's action where a user is acting, and stores action-history data containing place names indicating the places of user's action at a predetermined processing timing. In the case where, the place of user's action is a specific place unique to the user, where the user visits customarily or frequently, the user is allowed to enter an arbitrary name independent of the latitude and longitude. The name entered by the user is used as a pace name to be contained in action-history data. In this way, the apparatus obtains a place name appropriate for the user and the user can use the name conveniently as the place name of the user's action.
