Systems and methods for determining energy experienced by a user and associated with activity

摘要

A method is disclosed for evaluating shoes worn by a person for activity on ground, including the steps of determining forces of acceleration experienced by the person in a direction generally perpendicular to the ground, processing signals representative of the forces of acceleration over a time interval to determine energy experienced by the person while wearing the shoes, reporting the energy to the person, and evaluating the shoes based on the energy. Another method is disclosed for ratioing energy from two different locations on a person for determining energy experienced by the person during activity over ground.
