13 Emotional Interactive System Design

Recently, there is an increasing concern about the research of the non-functional demand in the interactive system, and in many cases the emotional factors can decide other non-functional demands. Emotional factors must be considered in a successful interactive system as well as the traditional usability. This paper argues that the relationship between emotion and interactive design is mainly reflected in three aspects: layout and color in an interface; design and use metaphor; interactive method, and accordingly puts forward the corresponding principles of human-computer interaction design.
