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.

Abstract
Methods, systems and apparatus for analyzing breathing of a user are disclosed. One method includes sensing motion of a first portion of the user, sensing motion of a second portion of the user, and generating a summed signal by inversely summing the sensed motion of the first portion of the user with the sensed motion of the second portion of the user. A breathing rate of the user is estimated based on the summed signal. Additionally, a breathing pattern of the user can be identified.
