Abstract
Systems and methods for detecting and counting steps. Acceleration data is used to determine acceleration norms. Peaks and valleys in the resulting acceleration norms data are then detected. These peaks and valleys are indicative of steps and are validated using measurements from gyroscopes and magnetometers. The systems and methods can thus be used to assist in location tracking and/or navigation.
