Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user-specific performance monitors provide unrealistic activity measurement results due to inaccuracies in performance parameter calculations, as they fail to effectively calibrate performance parameters without heart rate measurement.
Innovation Solution
A method and software product that associate activity information with heart rate information to calibrate user-specific performance monitors, allowing for the determination of performance parameters without direct heart rate measurement, using activity and association information to improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If activity measurement is used to determine performance parameters, then the performance monitor can operate without heart rate measurement, but the performance parameter values become unrealistic and inaccurate
Solution Approach 1:
The system performs preliminary calibration by measuring both activity information and heart rate information during calibration activities. This preliminary action creates an association between activity data and heart rate data, enabling the system to later determine performance parameters using only activity information without direct heart rate measurement, thus resolving the contradiction between ease of operation and measurement precision.
2Measurement precision
If heart rate measurement is used to determine performance parameters, then accurate performance parameter values are obtained, but the device complexity and measurement requirements increase
Solution Approach 1:
The invention extracts the essential calibration information by associating activity information with heart rate information during a calibration phase. Once the association is established, the system can extract performance parameter determinations using only activity information, removing the need for continuous heart rate measurement and thereby reducing device complexity while maintaining accuracy.
3Device complexity
If activity information alone is used to determine performance parameters, then the calibration process is simplified, but the performance parameter values do not provide realistic results
Solution Approach 1:
The system uses feedback from heart rate measurements during the calibration phase to adjust and refine the association between activity information and performance parameters. This feedback mechanism ensures that the simplified calibration process using only activity information still produces realistic and accurate performance parameter values by learning from actual heart rate responses.

AI summary
In the solution of the invention, an association is formed (702) between activity information characterizing the activity level of a user and a performance parameter value proportional to the heart rate information of the user, the activity information and heart rate information having been measured in a user-specific performance monitor, and the heart rate information being responsive to the activity level.
