    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.

    Evaluating feedback requirements for trust calibration in automated vehicles
    (it - Information Technology: Vol. 63, No. 2, 2021) Wintersberger, Philipp; Janotta, Frederica; Peintner, Jakob; Löcken, Andreas; Riener, Andreas
    The inappropriate use of automation as a result of trust issues is a major barrier for a broad market penetration of automated vehicles. Studies so far have shown that providing information about the vehicle’s actions and intentions can be used to calibrate trust and promote user acceptance. However, how such feedback could be designed optimally is still an open question. This article presents the results of two user studies. In the first study, we investigated subjective trust and user experience of (N=21) participants driving in a fully automated vehicle, which interacts with other traffic participants in virtual reality. The analysis of questionnaires and semi-structured interviews shows that participants request feedback about the vehicle’s status and intentions and prefer visual feedback over other modalities. Consequently, we conducted a second study to derive concrete requirements for future feedback systems. We showed (N=56) participants various videos of an automated vehicle from the ego perspective and asked them to select elements in the environment they want feedback about so that they would feel safe, trust the vehicle, and understand its actions. The results confirm a correlation between subjective user trust and feedback needs and highlight essential requirements for automatic feedback generation. The results of both experiments provide a scientific basis for designing more adaptive and personalized in-vehicle interfaces for automated driving.

    HapTech: Intelligent controls in public spaces through mid-air haptic interaction
    (Mensch und Computer 2023 - Workshopband, 2023) Rosbach, Emely; Muhammad, Muhammad; Talabani-Durmus, Larin; Maral, Muhammed; Ziegler, Carina; Reuter, Hannah; Lell, Alice; Hoffer, Sabrina; Peintner, Jakob; Riener, Andreas
    Recently, public spaces have seen a shift towards touch-free interaction to address hygiene concerns. HapTech, a prototype of a gesture-controlled interface with mid-air haptic feedback, offers a solution. It allows users to control essential functions like lights and HVAC without physical contact. To understand the impact of visual user interfaces, a Wizard-of-Oz study was conducted. The findings suggest that while including a visual UI improves self-explainability, it also leads to longer task completion time and errors. Striking a balance is crucial, emphasizing simplistic UIs for intuitive gesture language and optional visual feedback. This optimization enhances touch-free interaction and overall user experience in public environments. We conclude that the inclusion of a visual user interface influences gesture choice and task completion, but it plays a pivotal role in improving user experience and self-explainability.

    Haptic Journey: The integration of gesture-controls and mid-air haptic feedback into ticket machines to foster better hygiene in public spaces
    (Mensch und Computer 2023 - Workshopband, 2023) Ambacher, Julian; Fischer, Luci; Gaurav, Anand Bihari; Pietruschka, Maria; Spreng, Leoni; Wilkes, Jasmin; Zimmermann, Theresa; Peintner, Jakob; Riener, Andreas
    Since the outbreak of Covid-19, hygiene is a major issue, especially in public spaces. One example are public ticket vending machines (TVMs). With their contactless interaction, gesture-controlled interfaces offer a valid alternative to touchscreens and haptic buttons, which are still widely used in current machines. To explore the impact of mid-air haptic feedback combined with gesture-control we conducted interviews, an online survey and a usability study to measure user experience and user satisfaction. Our results show that hygiene plays a major role in public spaces. Furthermore, gesture-control combined with mid-air haptic feedback has the potential to provide more hygienic interaction that enhances user experience and usability compared to traditional TVMs.
