1. A method of monitoring human activity by a mobile device, comprising:
- 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;
counting a plurality of steps based on the accelerations;
determining a gait characteristic of the plurality of steps;
determining one or more user attributes based at least in part on historical data collected by the inertial sensor;
using a stride length to gait characteristic correlation to determine a stride length from the gait characteristic, wherein the correlation is based at least in part on the determined one or more user attributes; and
determining at least one of a distance traveled and a speed of travel based on the stride length.

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.
