Abstract
Methods for operating a processing system to generate accurate information representative of movement of a body from activity sensors such as tri-axial accelerometers. The system uses wavelet analysis and/or adaptive thresholds to provide quantitative measurements of a person's posture and/or activity, including low-speed activity, during daily living.
Claims35
A method for operating a processing system to generate information representative of movement of a body, comprising:
- receiving one or more kinematic or movement signals representative of movement of the body at the processing system;
- continuous wavelet transform processing the one or more movement signals by the processing system to generate continuous wavelet transform data;
- and
- determining, by the processing system, whether the body is moving as a function of the continuous wavelet transform data.
A method for operating a processing system to generate information representative of movement of a body, comprising:
- receiving one or more kinematic or movement signals representative of movement of the body at the processing system;
- processing the movement signals by the processing system to generate one or more step threshold levels representative of steps;
- and
- processing the movement signals by the processing system, including comparing the movement signals to the one or more step threshold levels, to identify patient steps.
