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.enuser experiencenon-instrumental qualitiessystem evaluationmobile phonesText/Journal Article1439-7854
