As a form of graphical information, signs, ranging from totems in ancient times to road and commercial signs in the modern society, accompany and influence the development of the human society. With the prosperous development of modern urban civilization, signs have become more diversified and individualized.
Signage and wayfinding systems are an emerging cross-disciplinary subject, which is composed of visual identification systems and wayfinding systems that are highly integrated to help visitors get integrated solutions for required information within the shortest possible time by offering functions such as information transfer, identification, recognition and image transmission in spatial and information environments on the basis of systematic design.
