This paper discusses new features that AI technology brings to the components of product design based on the background, origin, current situation and future development of AI technology. Based on new features of product design, the importance and design methods of emotional interaction design of intelligent product are proposed. Through literature review and case analysis, it is concluded that under the influence of AI, product design has transited from the stage of traditional material expression to the stage of virtual immersion experience, traditional product functions have advanced to intelligent function expansion, and traditional human-machine system also sees a more friendly interaction trend. Against this background, an intelligent emotional interaction method needs to be adopted for the product design as a link to connect users with the machine. Finally the emotional intelligent interaction design method is analyzed through the case of intelligent kitchen seasoning box design. In order to enhance the fresh experience of intelligent product interaction and contribute ideas and references for intelligent product design innovation in the future, the method of establishing multi-dimensional integrated intelligent interaction system and associative metaphorical dynamic graphic interaction is proposed.
