Notification Sync via Motion Sensor Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notification systems on mobile and wearable devices often generate repeated notifications, leading to user annoyance and missed alerts due to the inability to determine which device was lastly used by the user, resulting in unnecessary alerts from unattended devices.
Innovation Solution
A method that synchronizes notifications between mobile and wearable devices using motion sensors to determine which device was lastly used by the user, allowing only that device to generate notifications, thus minimizing redundant alerts and ensuring notifications are easily noticed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notifications are generated on both mobile and wearable devices independently, then the user may not miss any notifications, but repeated notifications cause user annoyance and environmental interference
Solution Approach 1:
The system uses motion sensors on both mobile and wearable devices to detect user movement and provides feedback about which device is currently being used. Based on this feedback, the notification generation is dynamically adjusted to prevent repeated notifications while ensuring at least one device generates the notification, thus resolving the contradiction between reliability and nuisance.
2Object-generated harmful factors
If the system determines which device was lastly used by comparing motion sensor data, then redundant notifications are avoided, but the system complexity increases due to synchronization requirements
Solution Approach 1:
The motion sensors on both mobile and wearable devices serve dual purposes: their primary function for motion detection and an additional function for determining notification generation rights. This multi-functionality approach reduces the need for separate complex synchronization mechanisms, as the existing motion sensors are leveraged for both purposes.
3Object-generated harmful factors
If notifications are generated only on the device lastly used by the user, then environmental interference is reduced, but the user may miss notifications if that device is not nearby
Solution Approach 1:
The system dynamically determines which device should generate notifications based on real-time motion sensor data. The notification generation right is not fixed but adapts to the user's current behavior, switching between mobile and wearable devices as needed. This dynamic approach ensures notifications are generated on the device most likely to be noticed while minimizing environmental interference.

AI summary
A method for generating notification is provided. The method includes following steps. A mobile device is paired with a wearable device. The mobile device has a first motion sensor, and the wearable device has a second motion sensor. Notification synchronization is performed between the mobile device and the wearable device. When an event is triggered and a corresponding notification should be generated, the mobile device generates the corresponding notification if the first motion sensor senses a motion is latter than the second motion sensor senses a motion. When an event is triggered and a corresponding notification should be generated, the wearable device generates the corresponding notification if the second motion sensor senses a motion is latter than the first motion sensor senses a motion.
