Alarm Generation Method for Continuous Biometric Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous blood glucose monitoring systems generate frequent alarms, leading to user fatigue and potential ignoring of critical alerts, while also sometimes triggering alarms against the user's wishes.
Innovation Solution
A method for generating alarms that maintains the alarm in an activated state for a set period, changing the alarm type selected by the user during this time, and synchronizing the alarm type with the operating mode of the receiver to prevent unwanted alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent alarms are generated to ensure user awareness of critical alerts, then reliability of alarm notification is improved, but user fatigue increases and users may ignore alarms
Solution Approach 1:
The system generates alarms at periodic intervals during an alarm period rather than continuously, allowing the alarm to be activated and deactivated in cycles. This periodic action maintains user awareness while providing relief intervals that prevent fatigue and ignore behavior.
Solution Approach 2:
The alarm type is dynamically changed during the alarm period based on elapsed time and user response. The system transitions between different alarm types (e.g., from more intrusive to less intrusive) to adapt to user state, maintaining effectiveness while reducing fatigue over time.
2Reliability
If alarms are generated continuously to ensure critical alerts are noticed, then alarm effectiveness is improved, but user inconvenience increases
Solution Approach 1:
The alarm operates in periodic cycles with activated and deactivated states during the alarm period. This provides sustained alertness while incorporating rest periods that improve user convenience and reduce inconvenience.
Solution Approach 2:
The system applies partial action by using different alarm types with varying intensities during the alarm period. Rather than maintaining maximum alarm intensity throughout, the system uses sufficient alarm action to ensure awareness while reducing excessive alarm action that causes inconvenience.
3Reliability
If alarm types are changed frequently to maintain user engagement, then alarm effectiveness is improved, but system complexity increases
Solution Approach 1:
The alarm type changes dynamically based on predetermined criteria such as elapsed time and user response patterns. This dynamic adjustment maintains effectiveness by adapting to user state while following systematic rules that prevent excessive complexity.
Solution Approach 2:
The system changes alarm parameters (type, intensity, frequency) during the alarm period based on elapsed time and user response. These parameter changes maintain alarm effectiveness while following structured progression patterns that limit system complexity.

AI summary
The present invention relates to a method for generating an alarm pertaining to continuous biometric data and, more specifically, to an alarm generation method in which, if an alarm condition is satisfied, an alarm is output to a user while maintaining the alarm in an activated state during a set alarm period, and changing the alarm type selected by the user during the alarm period, thereby enabling the user to be prompted to input information or take an action in response to the alarm without ignoring the alarm, while not causing inconvenience to the user due to frequent alarms; and when the alarm condition is satisfied, an operating mode of a receiver is determined and the alarm type, which has been set in accordance with the alarm condition, is changed to an alarm type corresponding to the operating mode of the receiver, thereby making it possible to prevent an alarm from being generated against the user's wishes.
