Abstract
A method and apparatus for estimating a step length of a user are disclosed. The method involves obtaining inertial data generated by an inertial sensor, extracting orthogonal motion components a plurality of directions, and estimating, based on the orthogonal motion components for each direction, a respective parameter that is indicative of energy expenditure by the user in the corresponding direction. The step length is then estimated, based on each estimated parameter indicating energy expenditure by the user, a corresponding step length.
