APPARATUS FOR DETECTING THE USER'S POSTURE BY TRACKING CHANGES IN THE CENTER OF GRAVITY OF THE USER AND METHOD THEREOF

摘要

An apparatus and method for detecting a user's posture by tracking a change in a user's center of gravity are provided. The method includes the steps of detecting a basic posture of the user using body information, pressure center information, and center of gravity information of the user, and using the changed center of pressure information and the changed center of gravity information of the user, Including the step of detecting the changed posture, the step of detecting the basic posture of the user, the step of receiving the user's body information and setting the user's basic information, corresponding to the user's body information from a standard body type database Receiving a standard center of gravity and a standard pressure center, detecting at least one first pressure center point on the at least one first pressure surface according to the user's basic posture by a pressure sensor module, the at least one first pressure center point Generating a first central pressure plane by using, comparing the standard pressure central surface and the first pressure central surface, and generating a first central point of gravity by changing the Z coordinate of the standard central point of gravity, the one Changing the first center of gravity using the first pressure center point, and receiving posture information corresponding to the at least one first pressure center point and the changed first center of gravity from the standard body type database, and The detecting of the changed posture of the user may include detecting at least one second pressure center point on at least one second pressure surface by the changed posture of the user by the pressure sensor module, the at least one second pressure center point Generating a second center of gravity by tracking the change of the one or more first pressure center points using, tracking the trajectory of the changed first center of gravity using the second center of gravity, and the user's body Generating the user's posture change range using information and the changed first center of gravity, and when a trajectory of the tracked first center of gravity is outside the posture change range, the at least one second center of pressure and the second 2 center of gravity If defined as noise, and the track of the tracked first center of gravity is within the posture change range, receiving posture information corresponding to the at least one second center of pressure and the second center of gravity from the standard body type database The basic posture, the at least one first pressure center point, the changed first center of gravity point, the changed posture, the at least one second pressure center point, and the second center of gravity are stored in a personal body type database.
