Quality-of-user-experience: a position paper

So far, research on quality-of-experience (QoE) has mostly been carried out in the area of multimedia communications, and user experience (UX) has addressed hedonic and pragmatic usage aspects of interactive applications. In the case of QoE, the meaningfulness of the application to the user and the forces driving the use have been largely neglected, while in the UX field, respective research has been carried out but hardly been incorporated in a model combined with the pragmatic and hedonic aspects. In this article, we take a step further approaching a comprehensive view of QoE and UX by adding eudaimonic aspects, such as meaningfulness and purpose-of-use, and by introducing the multidimensional construct of quality-of-user-experience (QUX). As meaning can be expected to play a major role in cyber-physical system (CPS) applications, we provide a characterization of CPS applications considering the professional/industrial and consumer/private domains, and analyze a number of characteristics that are relevant for users and their experience. In three exemplary scenarios, we illustrate the application of our concept and propose respective, not yet validated, QUX-models. Finally, we address related research challenges .
