System and Method for Tracking a Moving Person
First Claim
1. A system for tracking a moving person, the system comprising:
- a controller configured to receive acceleration data that characterizes an acceleration of the moving person in three dimensions, wherein the controller comprises;
a step rate component that determines a step rate for the person based on a vertical component of the acceleration data;
a body offset component that determines a body offset angle based on a spectral analysis of the acceleration data and the step rate; and
a velocity component that determines a reference velocity vector based on the body offset angle and the step rate.
