The Application of Iterative Design Approach in Tangible Interaction Design

The objective is to explore the driving effects of interactive prototypes in iterative design and promote the practical application of iterative design approach. Based on the iterative design approach,it analyzes the functions of prototypes in different phrases of a design process and takes interactive prototype as a guidance of design processes. In an interactive prototyping research project,a number of tangible interactive prototypes are built in which iterative design methods are explored and demonstrated by using prototype-driven design approach. It discusses the driving effects of the prototyping in an iterative design process through a series of case studies,from which we find it is necessary to introduce interactive prototype early in a design process and realize the self-iteration of the prototype.
