Abstract

See full text

Methods for providing swimmers with performance metrics, turn detection, and stroke rate detection are disclosed. An example method comprises mounting a wearable device comprising an accelerometer, gyroscope and processor on a swimmer's head, continuously measuring acceleration using said accelerometer and angular velocity using said gyroscope to provide acceleration and angular velocity signals to said processor, processing said acceleration and angular velocity signals to determine first roll and pitch angles, applying a correction to axes of said gyroscope based on said roll and pitch angles to determine corrected angular velocity signals, initializing a heading angle at a pre-defined, non-zero value, integrating said corrected angular velocity signals over a time window to determine changes to the heading angle, determining maximum and minimum heading angles within the time window, and, recording a turn when a difference between the maximum and minimum heading angles within the time window is at least approximately 180 degrees.
