1. A method of providing postural feedback comprising:
- receiving by a microprocessor data from a accelerometer, the microprocessor and the accelerometer comprising a sensor device attached to a user, the sensor device further comprising a feedback delivery apparatus;
normalizing by the microprocessor the received accelerometer data;
determining by the microprocessor a postural description of the user based on the normalized received accelerometer data, wherein the postural description comprises a movement state, wherein determining the postural description of the user comprises;
computing a sequence of accelerometer data features from the normalized received accelerometer data, andanalyzing the sequence of accelerometer data features according to a rule-based model to determine, in part, the postural description; and
triggering by the microprocessor the feedback delivery apparatus to output sensory feedback based on the postural description of the user.

Abstract
A system and method are described herein for a sensor device which biomechanically detects in real-time a user'"'"'s movement state and posture and then provides real-time feedback to the user based on the user'"'"'s real-time posture. The feedback is provided through immediate sensory feedback through the sensor device (e.g., a sound or vibration) as well as through an avatar within an associated application with which the sensor device communicates.
