The general tendency of design is that being based on human and the aim of Kansei engineering is to follow the structure of emotions based on human behaviors. As we know, Kansei appears in individual emotions and is able to create different feelings in human mind (Nagamachi, 2010) where Flow is a teleonomy of the self (Csikzentmihaly, 1992). However, Design has a convergent and divergent relation with needs and desires. Accordingly, designers are obliged to meet user’s desires but the implicit needs of such an emotional experience are difficult, partly because people express their emotions both consciously and unconsciously. Analyzing the relationship between Kansei and Flow, activities can have optimal behavior output. This article provides a new approach, which can be applied to capture the emotions of users and proposes a new framework of Kansei Engineering (KE) to handle the optimal experience of people besides their needs in a various tangible fields such as interior and product design. In this study we use the KE Model of Schütte because it is understandable and compatible with new tools. We use Flow in semantic and properties space and we created a Flow space during the synthesis step of this level.
