SYSTEM FOR DETERMINING THE STATE AND MOTION OF A HUMAN BODY USING AN OPTICAL SIGNAL, AND METHOD FOR DETERMINING THE STATE OF A HUMAN BODY

摘要

Provided is a system using an optical signal to determine the state and motion of a human body. The system for determining the state of a human body may comprise: an optical signal transmitter module configured to generate and output optical signals; an optical signal transfer module that is attachable to a part of a human body and comprising at least one optical signal transfer path including at least one cut end; and a human body state analyzer module configured to determine a change in the state of the human body by calculating a varying optical transfer rate in the at least one optical signal transfer path on the basis of a gap at the at least one cut end of the at least one optical signal transfer path. Here, a gap at one cut end of the at least one optical signal transfer path may be varied according to variations in the circumference of the part of the human body.
