Usability versus User Experience in the Context of the Design Process of Interactive Systems: Theory and Practice of Two Concepts

In general, HCI deals with the design, implementation and evaluation of interactive application systems and phenomena that occur between humans and computers when using such systems. It is an interdisciplinary field of research, particularly at the intersection of computer science, cognitive science and industrial psychology. The findings of the individual research areas should help to achieve the overarching goal of economically efficient and psychologically low-stress task processing on the computer. Traditionally, the measure of economically efficient and psychologically low-stress task processing is described by the term usability. Recently, a new term, user experience (UX), has become increasingly important in this context. UX is a relatively broadly defined term that also deals with the achievement of non-instrumental user needs for aesthetics, enjoyment (fun), creativity and social interaction. The thesis examines whether and how the new term relates to the traditional concept of usability. To this end, the two concepts are first to be described and compared following a detailed literature review. The comparison should also include methods for measuring the parameters associated with the terms. The theoretical results are to be supplemented with an empirical study using the example of the e-learning software Scholion, in which both the usability and the user experience of Scholion are to be examined.
