    Development and Validation of a German Version of the Player Experience Inventory (PXI)
    (Mensch und Computer 2022 - Tagungsband, 2022) Graf, Linda; Altmeyer, Maximilian; Emmerich, Katharina; Herrlich, Marc; Krekhov, Andrey; Spiel, Katta
    The Player Experience Inventory (PXI), initially developed by Abeele et al. (2020), measures player experiences among English-speaking players. However, empirically validated translations of the PXI are sparse, limiting the use of the scale among non-English speaking players. In this paper, we address this issue by providing a translated version of the scale in German, the most widely spoken first language in the European Union. After translating the original items, we conducted a confirmatory factor analysis (N = 506) to validate the German version of the PXI. Our results confirmed a 10-factor model—which the original authors of the instrument suggested— and show that the German PXI has valid psychometric properties. While model fit, internal consistency and convergent validity were acceptable, there was room for improvement regarding discriminant validity. Based on our results, we advocate for the German PXI as a valid and reliable instrument for assessing player experiences in German-speaking samples.

    Leaf your Chair Behind – Calm Persuasion for Frequent Sitting Breaks Among Office-Workers
    (Proceedings of Mensch und Computer 2024, 2024) Jung-Krenzer, Theresa; Kirchner-Krath, Jeanine; Retz, Celina; Altmeyer, Maximilian
    Sedentary behavior has been linked to numerous detrimental health outcomes. This is particularly pronounced among office workers. Sitting breaks can attenuate some of these detrimental health effects. Thus, our goal was to design a persuasive system to prompt frequent sitting breaks in the office. With our system we want to address two key issues of existing approaches: low compliance due to lack of motivation, and user annoyance with frequent prompts. Based on a literature review, we developed four design concepts each using a different prompt modality (appearance, audio, light, movement) and evaluated them qualitatively by conducting a focus group interview with a panel of workplace health management experts (N=5) and quantitatively in an explorative online study with our target demographic (N=39) rating the concepts’ perceived persuasiveness and obtrusiveness. Based on our findings, we derive design implications for researchers and practitioners, and demonstrate their technical feasibility by providing a proof-of-concept implementation.
