ABSTRACT
The emerging field of service design combines several methods mainly from the fields of product, software and interaction design, for designing the experience and interface to services. However, User eXperience design is not easy to understand because it is a new approach and covers many different fields (usability, psychology, marketing…). More often the design team members come from various domains with different cultural backgrounds such as engineers and marketing. Therefore, it is necessary to have a common definition to share the same understanding of this concept. In this paper, we investigate the main definitions proposed in the literature and the use of User eXperience in many disciplines other than computer science. The main goal of this paper is to find important ingredients from different fields allowing to defining and characterizing the User eXperience in service design. Thus we propose to extend an existing design tool (persona) in order to cover the whole of User eXperience components (hedonistic, aesthetic interaction, social factors...).
