Abstract
A method of monitoring human activity includes monitoring accelerations using an inertial sensor disposed at one of a plurality of locations on a human body, wherein at least one of the plurality of locations is not a foot location. A plurality of steps are counted based on the accelerations. A gait characteristic of the plurality of steps is determined. The characteristic is used to determine a stride length. At least one of a distance traveled and a speed of travel are determined based on the stride length.
