1. A method for analyzing breathing of a user, comprising:

  • generating a first motion signal, comprising sensing motion, by a first motion sensor, of a first portion of a body of the user;

    generating a second motion signal, comprising sensing motion, by a second motion sensor, of a second portion of the body of the user;

    generating a summed signal by inversely summing the first motion signal and the second motion signal;

    estimating a breathing rate of the user based on the summed signal comprising identifying a periodic component of the summed signal;

    identifying a breathing pattern of the user, comprising;

    generating a motion signature based on sensed motion of the summed signal;

    matching the motion signature with at least one of a plurality of stored motion signatures, wherein each stored acceleration signatures corresponds with a breathing pattern;

    identifying the breathing pattern of the user based on the matching of the motion signature with the stored motion signature.
