Today's progress in advanced technology has paradoxically caused the human being to harbor uneasiness and distrust towards technology. The concept of guiding human beings to better direct the relationship between man and technology is called human-centered theory. This concept attempts to reevaluate everything from human beings as the central existence to technology&sbquo and even the ideal state of society and environment as the background that demands such technology. Technology and environment in this case&sbquo in particular&sbquo mean information technology and environment. This human-centeredness is something that can be understood as the mutual relationship between the center and its surroundings. It is necessary to pay attention to the fact that subjectivity is sought deductively from surroundings and boundaries that define the human being that exists in the center. It does not consider the subjectivity of the human being as the ultimate in importance. It is necessary to consider that the root of this "ism" lies in inquiring after the nature of the objectivity that surrounds the human being as subject. In other words&sbquo this human-centered theory is required in the mutual relationship between human being a subject and environment&sbquo the age&sbquo systems&sbquo and society as environment. This is how the concept of human-centered design was born. The human-centeredness in this sense is systematized through the relationship of man and advanced technology and information technology in particular&sbquo called human science advanced technology&sbquo and is based on the standpoint of human science. It is not merely limited to the realm of universal design and considerations for harmonizing the environment and human being. It leads to the idea of seeking the essence of design with the quality of experience as its subject. In order for the human being to build with subjectivity the relationship with technology and information technology in particular&sbquo the relationship with various surroundings around the human being must be clear as the subject of design. The essence of human-centered design is that the essential function and effect of these designs will not become clear unless the subject as the center is structured with a design that is interactive with the objectivity that is the surroundings.
