PURPOSE: A posture correction system is provided to rapidly and accurately correct the wrong posture of a user using a proactive correction unit through correction unit transmitting the correction posture information. CONSTITUTION: An inertia sensor module(200) measures the movement of a user. A controller(300) calculates the correct posture information by comparing the posture information of the user measured by the inertia sensor module and the reference posture data. A calibrator(400) transfers the correct posture information transmitted from the controller to the user through a stimulation.
