Creative design research of product appearance based on human–machine interaction and interface

According to traditional design theory, the Function–Behavior–Structure design model pays more attention to the function and structure of the product. However this model still cannot strengthen the relationship between product appearance design and human–machine design effectively. This paper adopt converse design thinking and presents a improved design thinking methodology based on Constraint:Function–Behavior–Structure for product appearance design and give a general summarization of the features, methods and technology based on human–machine interaction and interface (HMI&I). At the same time it also combines with the behavior design of product related IT fields and constructs a new outline to improve the design of product appearance supported by the technology of computer aided design (CAD). Thus a new method about design thinking for CAD, a new abstract product design model and the key problem of design thinking based on HMI&I are addressed in this paper. The creative design theory that is driven by HMI&I will help in the development of a CAD software system and in the research of product design and manufacture. Additionally the trend of design thinking based on the technology of HMI&I are also analyzed and discussed at the end of the paper.
