HARMONIC INDEX ESTIMATION DEVICE, ESTIMATION SYSTEM, HARMONIC INDEX ESTIMATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18203334 titled 'HARMONIC INDEX ESTIMATION DEVICE, ESTIMATION SYSTEM, HARMONIC INDEX ESTIMATION METHOD, AND RECORDING MEDIUM
Simplified Explanation
The patent application describes a device for estimating a harmonic index related to the smoothness of movement of a person's waist. The device uses sensor data related to the movement of a person's foot, including spatial acceleration and spatial angular velocity, to extract a feature amount used for estimation.
- The device includes a communication unit that acquires feature amount data from sensor data related to foot movement.
- The feature amount data includes a feature amount used for estimation of a harmonic index related to the smoothness of waist movement.
- The device has a storage unit that stores an estimation model, which outputs an estimation value related to the harmonic index based on the input of the feature amount.
- An estimation unit inputs the feature amount data to the estimation model and estimates the harmonic index of the person.
- An output unit provides information associated with the harmonic index.
Potential applications of this technology:
- Assessing the smoothness of movement in physical therapy or rehabilitation settings.
- Monitoring and analyzing the gait patterns of individuals for research purposes.
- Providing feedback to individuals to improve their movement and posture.
Problems solved by this technology:
- Provides a quantitative measure of the smoothness of movement, which can be useful in assessing and monitoring physical conditions.
- Offers a non-invasive and objective method for evaluating movement patterns.
- Allows for personalized feedback and interventions to improve movement quality.
Benefits of this technology:
- Enables early detection and intervention for movement-related issues.
- Provides a more accurate and objective assessment of movement quality compared to subjective evaluations.
- Can be used in various settings, including healthcare, sports, and research.
