    Affinity for technology interaction and fields of study: implications for human-centered design of applications for public administration
    (Mensch und Computer 2020 - Tagungsband, 2020) Wessel, Daniel; Heine, Moreen; Attig, Christiane; Franke, Thomas
    Affinity for Technology Interaction (ATI) describes whether a person approaches or avoids interaction with technology [1], making it an important variable in human-centered design. To determine whether ATI will likely remain an important variable in the future, we compared the ATI scores of those who will develop applications (students of media and computer science) with those who will use them in a specific context (students of public administration). We also looked for possible selection biases when conducting online samples regarding technology, by comparing a self-selected online sample of public administration employees with a sample of students of public administration conducted in a classroom, in which no selection biases should have had occurred. To locate the samples in the general population we also compared them with a quota sample of the German population. Results indicate markedly different approaches to technology interaction between the student samples and the online sample being more similar to the media and computer science students. We discuss consequences for the human-centered design process, especially for understanding the users.

    ATI-S -- An Ultra-Short Scale for Assessing Affinity for Technology Interaction in User Studies
    (Mensch und Computer 2019 - Tagungsband, 2019) Wessel, Daniel; Attig, Christiane; Franke, Thomas
    In research and development in general, and in user-centered design (UCD) in particular, participants of studies have to be representative for the target audience. However, given the voluntary participation in user studies and an ensuing self-selection bias, participants of user studies likely prefer to engage with technology more strongly than the target audience in general (i.e., they have a higher affinity for technology interaction, ATI). Unchecked, this potential bias might lead to products that neglect important user groups or miss valuable market niches. At the same time, participants’ time is limited, so assessment of ATI must be economical. Thus, we propose an ultra-short ATI scale derived from the ATI scale by [10]. ATI-S was developed using theoretical considerations and empirical analyses. It provides a sufficiently reliable and valid assessment of ATI in conditions with strict time-constraints, in which the full ATI scale cannot be used.

    Mausparameter als Indikatoren für Hilfsbedürftigkeit in der MCI
    (Mensch und Computer 2018 - Tagungsband, 2018) Attig, Christiane; Then, Ester; Krems, Josef F.
    Affektive Zustände während der Mensch-Computer-Interaktion (MCI) äußern sich durch verschiedenste beobachtbare Indikatoren wie Mimik, Gestik oder physiologische Parameter. Die Erfassung dieser erfordert jedoch zusätzliche Sensoren, die in klassischen Computersystemen nicht implementiert und/oder intrusiv sind. Die Aufzeichnungen des natürlichen Nutzerinputs durch bereits vorhandene Eingabegeräte wie Maus und Tastatur ist hingegen einfach und nicht-intrusiv. In der vorliegenden Arbeit untersuchten wir ausgewählte Parameter basierend auf der Mausinteraktion (Geschwindigkeit, Unterbrechungen, Klickzahl) und deren Potenzial, Hilfsbedürftigkeit in der MCI abzubilden. Fünfzehn Probanden bearbeiteten dazu unterschiedlich schwierige Aufgaben im Statistikprogramm SPSS. Die Ergebnisse zeigen, dass sich die Mausinteraktion bei hoher (im Gegensatz zu niedriger) Hilfsbedürftigkeit durch eine geringere Mausgeschwindigkeit, weniger Klicks und längere Unterbrechungen auszeichnet.

    Trust in activity tracker measurement and its link to user acceptance
    (Mensch und Computer 2018 - Tagungsband, 2018) Trommler, Daniel; Attig, Christiane; Franke, Thomas
    Inaccuracies in data measurement can impair trustworthiness of activity trackers (i.e., wearable fitness devices) and, thus, constitute a usability challenge possibly impairing user acceptance. With the present research, we aim at advancing understanding of perceived trustworthiness of activity tracker measurement and its relevance for user acceptance. N = 79 users of activity trackers were surveyed regarding their daily interaction with the tracker, user experience, and user acceptance. Results indicated a substantial variance in perceived trustworthiness. Many users perceived suboptimal trustworthiness of the tracking of their activity data, indicating potential for optimization. Further, analyses showed that higher perceived trustworthiness of activity tracker measurement was indeed linked to higher user acceptance. The results highlight the potential of enhancing user acceptance of activity trackers by improving perceived trustworthiness of activity measurement.
