Title: AUTOMATIC GUIDANCE SYSTEM FOR CORRECT SITTING POSTURE
Abstract:
The present invention relates to an automatic guidance system for correct sitting posture, the system guiding correct sitting posture by automatically analyzing the sitting posture of a seated person using a chair or a cushion, and comprising: a seat package embedded in a chair or a cushion and having a pressure sensor array in which a plurality of pressure sensors are arranged in a line in the right and left directions; and a portable electronic device, which extracts a transverse center of contour (COC) through the outermost point at which a pressure value is measured from the plurality of pressure sensors, calculates, on the basis of pressure values measured by the plurality of pressure sensors, a transverse center of mass (COM) so as to extract a transverse posture variation vector having the transverse center of contour as a starting point and having the transverse center of mass as an ending point, and executes a warning or a program for correct posture guidance if the absolute size of the transverse posture variation vector is greater than a predetermined set value. Therefore, an accurate posture diagnosis can be made so as to be suitable for the sitting posture of a seated person.
