Who can briefly describe the origin and development of semiotics?

Semiotics is the study of semiotics, which was first put forward by Swiss linguist Sau Haour and American philosopher and founder of pragmatic philosophy at the beginning of this century. The former focuses on the significance of symbols in social life and is related to psychology; The latter focuses on the logical meaning of symbols and is related to logic [1]. Since 1960s, semiotics has been studied as a science. Now semiotics has become a scientific research, and its theoretical achievements have penetrated into many other disciplines. Design is closely related to semiotics. The word design comes from Latin design, which means to draw a mark [2]. English Design, which is widely used now, means mark. Learning and applying some principles of semiotics to help designers "mark" cannot be said to be an important way for designers.

The origin of symbols is labor. As early as the primitive society, people have both practical and aesthetic needs, and have begun to engage in primitive design activities, enriching their lives with conscious or unconscious symbolic behaviors. From our ancestors' knotting notes to song and dance totems, they are all information symbols to maintain the traditional social order.

Symbol is the medium to carry and transmit information, and it is a simplified means to understand things, which is manifested as meaningful codes and code systems [3]. Of course, the extension of the symbol concept is quite extensive. As a kind of nonverbal symbol, the symbol in design has many characteristics of linguistic symbol, which makes semantics also have practical guiding role in design. Generally speaking, the elements and basic means of design can be regarded as symbols, and the purpose of expressing feelings can be realized by processing and integrating these elements.
