    Enthusiasts, Pragmatists, and Skeptics: Investigating Users’ Attitudes Towards Emotion- and Personality-Aware Voice Assistants across Cultures
    (Mensch und Computer 2022 - Tagungsband, 2022) Ma, Yong; Abdelrahman, Yomna; Drewes, Heiko; Petz, Barbarella; Alt, Florian; Hussmann, Heinrich; Butz, Andreas
    Voice Assistants (VAs) are becoming a regular part of our daily life. They are embedded in our smartphones or smart home devices. Just as natural language processing has improved the conversation with VAs, ongoing work in speech emotion recognition also suggests that VAs will soon become emotion- and personality-aware. However, the social implications, ethical borders and the users’ general attitude towards such VAs remain underexplored. In this paper, we investigate users’ attitudes towards and preferences for emotionally aware VAs in three different cultures. We conducted an online questionnaire with N = 364 participants in Germany, China, and Egypt to identify differences and similarities in attitudes. Using a cluster analysis, we identified three different basic user types (Enthusiasts, Pragmatists, and Skeptics), which exist in all cultures. We contribute characteristic properties of these user types and highlight how future VAs should support customizable interactions to enhance user experience across cultures.

    Out of Shape, Out of Style, Out of Focus
    (Informatik-Spektrum: Vol. 37, No. 5, 2014) Butz, Andreas; Beyer, Gilbert; Hang, Alina; Hausen, Doris; Hennecke, Fabian; Lauber, Felix; Loehmann, Sebastian; Palleis, Henri; Rümelin, Sonja; Slawik, Bernhard; Tausch, Sarah; Wagner, Julie; Hussmann, Heinrich
    Wenn sich Computertechnik nahtlos in unseren Alltag integrieren soll, dann erfordert dies neue Bauformen und Interaktionsstile, die auf die menschlichen Fähigkeiten abgestimmt sind. Dieser Artikel zeigt drei Gestaltungsaspekte auf, mittels derer wir eine solche Integration erreichen können. Er beschreibt in aller Kürze eine Reihe von Prototypen der Arbeitsgruppen Medieninformatik und Mensch-Maschine-Interaktion an der LMU München und reflektiert kurz den verwendeten methodischen Ansatz.

    Tangible Interfaces Support Young Children’s Goal Interdependence
    (Mensch und Computer 2022 - Tagungsband, 2022) Li, Yanhong; Gao, Zhenhan; Egger, Sabrina; Mayer, Sven; Hussmann, Heinrich
    Understanding how to contribute to group work is challenging, especially for young children. To have a productive group process, we need to know the mechanism of positive interdependence, which is a fundamental element of successful collaboration. Unfortunately, although there are many suggestions for promoting positive interdependence with tangible technologies, there are few guidelines for structuring children’s interdependent collaboration. Therefore, we designed two tangible games, UnitRry and CollabMaze, using weak and strong goal interdependent designs. We conducted two user studies with 32 children. Our investigation revealed three main findings. First, weak and strong goal interdependent interfaces had high enjoyment and interdependence. Second, tangible interfaces help young children have more idea communication and need less time to solve the tasks. Finally, young children using tangible interfaces were more engaged in the tasks. In the long run, our results can improve the design of tangible interfaces for young children’s collaboration and help them have a better collaborative experience. Furthermore, our findings showed the value of tangible technologies compared with tablet applications in facilitating children’s collaboration.

    A test-oriented HMI specification model for model-based testing of automotive human-machine interfaces
    (INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 2, 2010) Duan, Linshu; Hussmann, Heinrich; Höfer, Alexander
    While model-based testing is widely-used for function tests, testing the human-machine interface (HMI) remains a manual, demanding and time consuming task. Numerous research efforts have been addressing model-based HMI testing in the last years. However the existing approaches cannot serve our test purposes or needs. In the research project at AUDI AG a model-based testing approach is proposed for testing both the logical behavior and the graphical interface of automotive infotainment HMIs. In this paper we focus on menu behavior tests and introduce some important details of the test-oriented specification model. A test-oriented HMI specification model describes the expected menu behavior and contains needed information for the test generation. Methods of test generation and execution will be introduced briefly.

    Understanding Algorithms through Exploration: Supporting Knowledge Acquisition in Primary Tasks
    (Mensch und Computer 2019 - Tagungsband, 2019) Eiband, Malin; Anlauff, Charlotte; Ordenewitz, Tim; Zürn, Martin; Hussmann, Heinrich
    We investigate exploration as an alternative to explanation to improve user understanding of algorithms and algorithmic decision-making. Drawing on complex problem-solving as defined in cognitive science, we conducted a think-aloud study in the lab (N=10) as well as an MTurk online study (N=123) using a flight booking scenario to see if and how exploration supports \textit{knowledge acquisition} in two different tasks. One group was told to focus on booking the cheapest flight (knowledge acquisition as a secondary task), the other on understanding the system logic (knowledge acquisition as a primary task). Our results indicate that exploration, even as a secondary task, may contribute to knowledge about the underlying algorithm. However, our study also suggests that the overall knowledge acquired through exploration is limited in the sense that it gives people an idea of how a system works, rather than teaching them concrete rules they can recall. Overall, we conclude that exploration presents a design opportunity to interweave knowledge acquisition with users' primary task, and may thus contribute to (but not substitute) existing design solutions for supporting users in understanding algorithmic decision-making.

    Why did you stop? - Investigating Origins and Effects of Interruptions during Mobile Language Learning
    (Mensch und Computer 2021 - Tagungsband, 2021) Draxler, Fiona; Schneegass, Christina; Safranek, Jonas; Hussmann, Heinrich
    The technological advances of smartphones facilitate the transformation of learning from the classroom to an activity that can happen anywhere and anytime. While micro-learning fosters ubiquitous learning, this flexibility comes at the cost of having an uncontrolled learning environment. To this point, we know little about the usage of mobile learning applications, particularly the occurrence of interruptions and the harm they cause. By diverting users’ attention away from the learning task, interruptions can potentially compromise learning performance. We present a four-week in-the-wild study (N = 12) where we investigate learning behavior and the occurrence of interruptions based on device logging and experience sampling questionnaires. We recorded 276 interruptions in 327 learning sessions and found that interruption type as well as users’ context influence learning sessions and the severity of the interruption (i.e., session termination likeliness). We discuss challenges and opportunities for the design of automated mechanisms to detect and mitigate interruptions in mobile learning.
