Notification Control for Mobile Users via Acceleration Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices lack an effective method to adjust notification timing based on the user's moving state, leading to suboptimal notification recognition, especially in dynamic environments.
Innovation Solution
An electronic device equipped with a controller and notificator that distinguishes user moving states using acceleration sensors and adjusts notification time periods accordingly, allowing for sound or vibration notifications based on stop, walking, or running states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification time period is extended to improve recognition during moving states, then notification reliability is improved, but device complexity increases due to state detection and adaptive control mechanisms
Solution Approach 1:
The notification system automatically adjusts its own time period based on detected user movement states without requiring manual intervention. The controller monitors acceleration sensor data, determines whether the user is moving or stationary, and autonomously extends or reduces notification duration accordingly, enabling the system to self-optimize notification delivery.
Solution Approach 2:
The notification time period parameter is dynamically changed based on the user's movement state. When movement is detected, the notification time period is extended to ensure recognition; when stationary, the standard time period is used. This parameter adaptation resolves the contradiction by making notification reliability context-dependent rather than fixed.
2Reliability
If notification time period is extended for moving users, then notification effectiveness is improved, but loss of time increases due to longer notification durations
Solution Approach 1:
The notification time period transitions from a static fixed value to a dynamic variable that adapts to user context. The system continuously monitors movement state and adjusts notification duration in real-time, extending it only when necessary (during movement) and maintaining standard duration when unnecessary (when stationary), thus optimizing effectiveness while minimizing time loss.
Solution Approach 2:
The system uses acceleration sensor feedback to determine user movement state and adjusts notification time period accordingly. This closed-loop control ensures notifications are extended only when the user is moving and likely to miss them, while avoiding unnecessary extensions when the user is stationary and can immediately perceive notifications, thereby balancing effectiveness with time efficiency.

AI summary
An electronic device includes a controller for distinguishing a moving state of a user, and a notificator for notifying the user of occurrence of a predetermined event by sound or vibration. The controller decides a notification time period for the notificator according to the moving state at the time of the occurrence of the event, and can thereby adjust the notification time period for the notificator according to the moving state of the user.
