Adaptive Audio Signal Control for Exercise Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices for reproducing human perceptual signals, such as music players, do not optimize user performance for health benefits, as they fail to adapt the signal in sync with the user's pace and physical state effectively, leading to suboptimal motivation and relaxation.
Innovation Solution
An electronic device with electronic circuitry that selects and adapts human perceptual signals, including audio, video, and tactile feedback, based on a user's pace and physical state, adjusting tempo and content to motivate or relax the user as needed, while maintaining a predefined target heart rate or exercise intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the audio signal tempo is synchronized with the user's current pace, then the user experiences comfort and relaxation, but the user is not motivated to improve their physical performance
Solution Approach 1:
The system dynamically adjusts the audio signal tempo based on the user's current pace and target pace. When the user's pace is below the target, the system increases the tempo to motivate improvement. When the user achieves the target pace, the system maintains synchronization to provide comfort and relaxation. This dynamic adjustment resolves the contradiction by making the system adaptive to different performance states.
Solution Approach 2:
The system changes the tempo parameter of the audio signal based on the user's performance state. By adjusting the tempo parameter upward when performance is suboptimal and maintaining it when performance is optimal, the system resolves the contradiction between comfort and performance motivation.
2Productivity
If the audio signal tempo is increased to motivate the user to reach target pace, then physical performance improves, but the user experiences stress and discomfort
Solution Approach 1:
The system dynamically controls the tempo adjustment based on the gap between current and target pace. When the user approaches or reaches the target pace, the system reduces or stops tempo increases to maintain comfort. This dynamic control resolves the contradiction by balancing motivation with comfort based on real-time performance feedback.
Solution Approach 2:
The system uses feedback from the user's pace measurement to control tempo adjustments. By continuously monitoring whether the user is approaching the target pace, the system adjusts the tempo accordingly, resolving the contradiction between performance improvement and user comfort through closed-loop control.
3Productivity
If the system continuously adapts the audio signal to the user's pace, then user performance is optimized, but the device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-processing the audio signal and preparing tempo adjustment parameters before they are needed. The electronic circuitry is configured to handle pace detection and tempo adjustment logic in advance, reducing the complexity of real-time adaptation during actual use.
