In the process of developing innovative product concepts, user's needs and technology has been generally regarded as a major driver of innovation [2,9]. And although interaction, being the contact point of the actual user and products or services, has a very high significance, they have been overlooked because they were considered to be dependent factors of products and technologies. The reason for this was because interactions were hard to manipulate and also because they weren't tangible . Being aware of these limitations, there are ongoing researches and studies on the properties of interactivity found in interaction between UX and products . Importance of interactivity and the possibility of interactivity being a driving factor of a new product development attracted attention in this study. Also, a method for extracting functional needs and new product domain was developed based on interactivity, and the effectiveness of this method was checked by using in the process of designing an organic user interface concept.
