Adaptive Safety Notification Control for User Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems fail to notify users or supervisors when a user deviates from a set route or area, especially if the deviation occurs near safe zones or when the user is heading towards potentially unsafe areas.
Innovation Solution
A user device equipped with an acquisition section to determine the user's current position and a control section that decides whether to implement a notification to return to the set route or area based on safety concern rankings, which are generated by a server and sent to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is implemented whenever user deviates from set route or area, then safety monitoring coverage is improved, but false alarms increase and user convenience deteriorates
Solution Approach 1:
The patent applies local quality by differentiating notification behavior based on the specific location where deviation occurs. Instead of uniform notification for all deviations, the system evaluates the safety level of the specific area where the user deviates. High-risk areas (near intersections, water bodies, cliffs) trigger notifications while low-risk areas do not, making the notification system adaptive to local conditions rather than applying a single rule globally.
2Ease of operation
If notification is suppressed when user is near safe zones, then user convenience is improved, but safety monitoring reliability deteriorates
Solution Approach 1:
The patent changes the parameter of notification threshold based on the environmental context. The system dynamically adjusts whether to notify by considering parameters such as proximity to intersections, water bodies, and cliffs. This parameter-based adaptation allows the system to maintain high reliability in dangerous areas while providing convenience in safe zones, resolving the contradiction between monitoring reliability and user convenience.
3Reliability
If age-based notification criteria are applied, then safety of young users is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining age-based notification criteria and safety level thresholds before actual use. The system stores predetermined rules that link user age groups to specific notification behaviors and safety level thresholds. When a user deviates, the system simply matches the user's age group against pre-established criteria rather than performing complex real-time calculations, thus improving safety for young users while minimizing system complexity.

AI summary
A user device, including a first processor, the first processor being configured to: acquire a current position of a user and, in a case in which the user has deviated from a set route or a set area, control whether or not to cause a notification unit to implement a notification to return to the set route or the set area based on ranking information representing a ranking of concern with respect to safety of the user.
