Hf: User Experience of Interaction with Technical Systems: Theories, Methods, Empirical Results and Their Application to the Development of Interactive Systems Sascha Mahlke

Today, people use interactive systems to accomplish many of their professional and personal goals. The use of interactive products has become an integral part of our everyday lives. In response, interactive system development does not exclusively focus on design of useful and usable products anymore, but takes the entire user experience into account to be successful. But what determines a good user experience?To answer this question, an approach to user experience of interaction with technical systems is presented that makes theoretical, methodological, and empirical contributions. A user experience framework introduces instrumental and non-instrumental quality perceptions as well as emotional user reactions as central components of user experience. The assessment of non-instrumental quality perceptions and emotional user reactions is focused in the methodological section and the results of three studies on portable audio players support most of the assumptions made in the experience framework. In conclusion, recommendations are made to incorporate user experience design goals already in early stages of the development process of interactive systems.
