Abstract
A method of operating an inertial sensor module includes receiving a stream of inertial sensor data representing activity of a user of an electronic device and generating a plurality of wavelet sub-bands by performing a wavelet transform on the inertial sensor data. The method includes identifying a wavelet sub-band of highest energy from the plurality of wavelet sub-bands, generating augmented inertial sensor data by combining the wavelet sub-band of highest energy to the inertial sensor data, and identifying a first transition in the activity of the user based on the augmented inertial sensor data.
