Action Notification System Using Motion Waveform Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise information measurement apparatuses lack the capability to deepen connections between individuals, as they primarily focus on personal data collection and do not effectively facilitate communication or notification of user actions to others.
Innovation Solution
An action notification system that includes an exercise information measurement apparatus with a body motion sensor, a communicator, and an output device, which determines user actions based on detected motion and transmits characteristic information of the motion waveform to an electronic device, allowing the device to operate a vibrator, speaker, or light emitter to notify others of the user's actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If continuous communication monitoring is implemented to enable real-time action notification, then notification responsiveness is improved, but power consumption increases
Solution Approach 1:
The system transitions from continuous monitoring to periodic sampling of motion data. The motion data acquisition unit acquires data at predetermined intervals, and the notification determination unit checks for actions at these periodic intervals, enabling real-time notification while significantly reducing power consumption by keeping the communication unit in low-power mode between sampling points.
2Measurement precision
If frequent communication is used to transmit action data, then notification accuracy is improved, but power consumption increases
Solution Approach 1:
The system extracts and transmits only essential notification data (action type and timing) rather than continuous motion data streams. The notification data transmission unit sends only the determined action information to the external electronic device, reducing communication frequency and power consumption while maintaining notification accuracy.
3Measurement precision
If motion data is continuously acquired and transmitted, then action detection accuracy is improved, but device complexity increases
Solution Approach 1:
The system segments the data processing function into two parts: the motion data acquisition unit remains in the wearable device for local action determination, while the notification data transmission unit communicates with an external electronic device for data storage and analysis. This segmentation reduces the complexity of the wearable device while maintaining action detection accuracy through distributed processing.
