    7th Workshop "Automotive HMI”: Safety meets User Experience (UX)
    (Mensch und Computer 2018 - Workshopband, 2018) Riener, Andreas; Geisler, Stefan; van Laack, Alexander; Frison, Anna-Katharina; Detjen, Henrik; Pfleging, Bastian
    Automotive user interfaces and automated vehicle technology pose numerous challenges to support all diverse facets of user needs. These range from inexperienced, thrill-seeking, young novice drivers to elderly drivers with a mostly opposite set of preferences together with their natural limitations. To allow assessing the (hedonic) quality of automotive user interfaces and automated driving technology (i. e., UX) already during development, the proposed workshop is dedicated to the quest of finding objective, quantifiable criteria to describe future driving experiences. The workshop is intended for HCI, AutomotiveUI, and “Human Factors” researchers and practitioners as well for designers and developers. In adherence to the conference main topic “Interaktion – Verbindet – Alle”, this workshop calls in particular for contributions in the in the areas of human factors and ergonomics (user acceptance, trust, user experience, driving fun, natural user interfaces, etc.) with focus on hedonic quality and design of user experience to enhance the safety feeling in ADS.

    8th Workshop Automotive HMIs: UI Research in the Age of New Digital Realities
    (Mensch und Computer 2019 - Workshopband, 2019) Riener, Andreas; Geisler, Stefan; Pfleging, Bastian; von Sawitzky, Tamara; Detjen, Henrik
    Even though many aspects of automated driving have not yet become reality, many human factors issues have already been investigated. However, recent discussions revealed common misconceptions in both research and society about vehicle automation and the levels of automation levels. This might be due to the fact that automated driving functions are misnamed (cf. Autopilot) and that vehicles integrate functions at different automation levels (L1 lane keeping assistant, L2/L3 traffic jam assist, L4 valet parking). The user interface is one of the most critical issues in the interaction between humans and vehicles – and diverging mental models might be a major challenge here. Today’s (manual) vehicles are ill-suited for appropriate HMI testing for automated vehicles. Instead, virtual or mixed reality might be a much better playground to test new interaction concepts in an automated driving setting. In this workshop – motivated by the conference theme – we will look into the potential of new digital realities for concepts, visualizations, and experiments in the car, e. g., by replacing all the windows with displays or transferring the entire environment into a VR world. We are further interested in discussing novel forms of interaction (speech, gestures, gaze-based interaction) and information displays to support the driver/passenger.

    9thWorkshop Automotive HMIs: Natural and Adaptive UIs to Support Future Vehicles
    (Mensch und Computer 2021 - Workshopband, 2021) Riener, Andreas; Pfleging, Bastian; Detjen, Henrik; Braun, Michael; Peintner, Jakob
    Modern vehicles allow control by the driver with multimodal user interfaces (UIs), touch interaction on screens, speech input, and mid-air gestures. Such UIs are driver-focused and optimized for limited distraction to not compromise road safety in manual driving. Nevertheless, they are often complex and it might be difficult to find specific features. Automated driving in L3+ will disrupt the design of automotive UIs as drivers become passengers, at least for certain parts along the way. Similarly, the car is being transformed into a social space where passengers can be granted control over systems because they can devote their full attention without imposing safety risks. The complexity of advanced driver assistance, in-vehicle information and interaction systems requires explanation to the user, e.g., in which state the system is, interaction possibilities, expectations from the driver or take over timing. We expect novel technologies to allow for natural interaction and adaptivity to design valuable and future-proof interaction concepts for the changing interior of (automated) vehicles. The goal of this workshop is, thus, to discuss how natural and adaptive user interfaces can help to solve the mentioned challenges and to identify opportunities for future research and collaboration.

    Categorization of Volunteers and their Motivation in Catastrophic Events
    (Mensch und Computer 2016 – Workshopband, 2016) Detjen, Henrik; Volkert, Susanne; Geisler, Stefan
    In catastrophic events, the potential of help has grown through new technologies. Voluntary help has many forms. Within this paper different categories of voluntary help are suggested. Those categories are based on properties like organizational structures, helping process, kind of prosocial behavior and many more. A focus is clearly on the organizational structure and motivational aspects of helper groups. Examples are given for each category. The categorization’s aim is to give a brief overview of possible properties a group of system users could have.

    Exploring Users' Perceived Control over Technology
    (Mensch und Computer 2021 - Tagungsband, 2021) Sieger, Leonie Nora; Detjen, Henrik
    Intelligent systems become more and more a part of our everyday lives and typically act autonomously. Design guidelines and constructs related to the control of traditional systems often do not apply to them. Still, perceived control over these systems is important to users and affect acceptance and intention to use them. This paper presents an explorative online study. Participants named systems over which they sense much or less control and described features and properties that lead to that perception or that affect their desire for control. We found that (1) perceived control is strongly influenced by not directly control-related design features such as effective or efficient use, (2) poor comprehensibility and malfunctioning are highly affecting users control feeling, (3) users value customizability and the possibility for personalization of systems, (4) people are highly aware of privacy control issues of modern online connected technology, and (5) smart systems face the same control-related challenges as non-smart systems, but suffer from still being new to the users. Our findings help to understand the complex phenomena of perceived control over system with different levels of intelligence and autonomy from the users’ perspective and give suggestions for the design of future systems.

    Rescue on the Road: Design Recommendations for Vehicle Assistant Systems to Support Effective First Aid Measures
    (Mensch und Computer 2022 - Tagungsband, 2022) Detjen, Henrik; Schneegass, Stefan
    One of the main goals of driving assistant systems is to prevent road accidents. However, if an accident has happened, system support is comparably sparse. In this paper, we, therefore, focus on the period after an accident has happened and conduct interviews (N = 7) with experienced rescue workers. We provide insights into the rescue process and initial design requirements, as well as a classification of potential post-accident systems’ roles (accident scout, virtual first responder, virtual first aid partner, chronologist). Overall, an extension of post-accident assistant systems could be a meaningful step to improving future road safety concepts.

    Teilautomatisiertes Fahren via Sprachsteuerung: Erwartungen und Anforderungen
    (Mensch und Computer 2018 - Workshopband, 2018) Detjen, Henrik; Geisler, Stefan; Salini, Maurizio; Wozniak, Martin; Borgmann, Colja
    Durch den technischen Fortschritt in der Spracherkennung und -verarbeitung wird Sprache als Interaktionsform auch in Fahrzeugen, z.B. zur Bedienung von Infotainmentsystem, immer populärer. Die Steuerung von teilautomatisierten Fahrzeugen über Sprache ist bisher wenig erforscht. Ziel dieser Arbeit ist es unter der grundsätzlichen Annahme der Eignung von Sprachsteuerung für teilautonome Fahrzeuge, Nut-zererwartungen und spezielle Anforderungen an eine Sprachsteuerung für die grundlegenden Fahrmanöver zu identifizieren. Aus den Ergebnissen eines Expertenworkshops und einer explorativen Videostudie werden Anforderungen und Sprachkommandos abgeleitet.

    User-Defined Voice and Mid-Air Gesture Commands for Maneuver-based Interventions in Automated Vehicles
    (Mensch und Computer 2019 - Tagungsband, 2019) Detjen, Henrik; Faltaous, Sarah; Geisler, Stefan; Schneegass, Stefan
    For highly automated vehicles (AVs), new interaction concepts need to be developed. Even in AVs, the driver might want to intervene and override the automation from time to time. To create the possibility of control, we explore vehicle control through maneuver-based interventions. Thereby, we focus on explicit, contact-less interaction, which could be beneficial in future AV designs, where the driver is not necessarily bound to classical controls. We propose a set of freehand gestures and keywords for voice control derived in a user-centered design process. Further, we discuss properties, applicability and user impressions of both interaction modalities. Voice control seems to be an efficient way to select a maneuver and free-hand gestures could be used, if voice channel is blocked, e.g., through conversation with passengers.

    Workshop on Generative Artificial Intelligence in Interactive Systems: Experiences from the Community
    (Mensch und Computer 2024 - Workshopband, 2024) Zakreuskaya, Anastasiya; Münch, Tobias; Detjen, Henrik; Mayer, Sven; Elagroudy, Passant; Pfleging, Bastian; Draxler, Fiona; Weyers, Benjamin; Gruenefeld, Uwe; Auda, Jonas; Titov, Waldemar; Mackay, Wendy E.; Buschek, Daniel; Kosch, Thomas
    Generative Artificial Intelligence (GenAI) is establishing itself in academia and industry through accessible implementations like ChatGPT and Stable Diffusion. Subsequently, GenAI is changing the interaction paradigms between users and computers. Currently, many individual approaches exist to leverage these tools, creating various strategies and agendas for using them in HCI research. Thus, we expect this will change how researchers design and create interactive interfaces. This workshop facilitates a common understanding of GenAI concerning HCI in which participants will share and discuss their experiences using GenAI and Large Language Models (LLMs) in HCI research. In this workshop, the potential of GenAI for Human-Computer Interaction will be explored and discussed with the research community through position papers, research statements, and opinions, thereby creating comprehensive practical insights synthesizing collective experience and strategies with real-world examples.
