Through the research of the visualization of the human-based three-dimensional shape domain, establish the three-dimensional spatial extent of human’s function space. And coordinate the difference of function space between individuals and groups. It is based on the morphological characteristics, physical features and psychological characteristics of human. Then achieve the match of the data of body and design parameters of products. Thus integrate ergonomics into the early process of design. And complete the change of the mode of space design from dimension driven to 3D human body model-driven. The research of human body’s domain will definite the way and standards of interaction space between men and machines. Thus the parameters of human body become precise, three-dimensional and instrumental. Solve the discord of relationship between people and objects, people and environment, performance and environment. To realize the expression of man’s functions in the product itself and the interaction with them.
