    The Diversity of Non-instrumental Qualities in Human-Technology Interaction
    (MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Mahlke, Sascha; Lemke, Iris; Thüring, Manfred
    Quality aspects that go beyond the instrumental value of an interactive system are one area of research in the field of user experience. In this paper, we describe an approach to the measurement of non-instrumental qualities that defines aesthetic and symbolic aspects as main sub-categories and discuss further relevant sub-dimensions. An exemplary study on three mobile phones is presented that used the discussed assumptions as theoretical basis and applied various questionnaire dimensions from the literature. The results demonstrate the usefulness of the approach and show that a consideration of diverse aspects of non-instrumental qualities makes is possible to better explain usersâ overall judgments. Implications for the evaluation and design of interactive systems and future work are discussed.

    Validating a Sociotechnical Heuristic Evaluation Method
    (Mensch und Computer 2019 - Tagungsband, 2019) Thewes, Felix; Kluge, Annette; Herrmann, Thomas
    The usefulness of a set of heuristics for the evaluation of sociotechnical systems will be examined. The usefulness of this evaluation is comparable to heuristics of interactive systems. The criterion of such usefulness include, whether persons who are not necessarily experts at the intersection between work design and sociotechnical design find more aspects with the help of sociotechnical heuristics which give critical or positive indications for the evaluation of a sociotechnical solution. An experiment with 60 participants shows that the intuitive assumption that more of such aspects could be found with the knowledge of heuristics cannot be confirmed for individual students. The use of heuristics supports a more even distribution of the found aspects across different categories. After evaluating the outcome of this study, it becomes clear that more detailed investigations on the effectiveness of sociotechnical heuristics are necessary and which special methodological requirements have to be observed.
