- WorkshopbeitragAdaptive Dark Mode: Investigating Text and Transparency of Windshield Display Content for Automated Driving(Mensch und Computer 2019 - Workshopband, 2019) Riegler, Andreas; Riener, Andreas; Holzmann, ClemensWindshield displays are a promising technology for automotive application. In combination with the emergence of highly automated vehicles, chances are that work-related activities will become more popular on the daily commute to and from work. While windshield displays can show content relevant for non-driving related activities, little information is available on how potential users would utilize these displays in terms of text and background color as well as transparency usage. In this paper, we present the results of two user studies (pilot study: N = 10, main study: N = 20) addressing this issue. Findings from quantitative measurements and qualitative pre-/post study surveys and interviews suggest a strong preference for the chat window being located on the driver side presented in dark mode with adaptive background transparency levels based on the luminance of the outside environment.
- ZeitschriftenartikelAugmented Reality for Future Mobility: Insights from a Literature Review and HCI Workshop(i-com: Vol. 20, No. 3, 2021) Riegler, Andreas; Riener, Andreas; Holzmann, ClemensThere is a growing body of research in the field of interaction between drivers/passengers and automated vehicles using augmented reality (AR) technology. Furthering the advancements and availability of AR, the number of use cases in and around vehicles rises. Our literature review reveals that in the past, AR research focussed on increasing road safety and displaying navigational aids, however, more recent research explores the support of immersive (non-)driving related activities, and finally enhance driving and passenger experiences, as well as assist other road users through external human-machine interfaces (HMIs). AR may also be the enabling technology to increase trust and acceptance in automated vehicles through explainable artificial intelligence (AI), and therefore help on the shift from manual to automated driving. We organized a workshop addressing AR in automotive human-computer interaction (HCI) design, and identified a number of challenges including human factors issues that need to be tackled, as well as opportunities and practical usages of AR in future mobility. We believe that our status-quo literature analysis and future-oriented workshop results can serve as a research agenda for user interface designers and researchers when developing automotive AR interfaces.
- ZeitschriftenartikelAugmented Reality Windshield Displays and Their Potential to Enhance User Experience in Automated Driving(i-com: Vol. 18, No. 2, 2019) Riegler, Andreas; Wintersberger, Philipp; Riener, Andreas; Holzmann, ClemensIncreasing vehicle automation presents challenges as drivers of highly automated vehicles become more disengaged from the primary driving task. However, even with fully automated driving, there will still be activities that require interfaces for vehicle-passenger interactions. Windshield displays are a technology with a promising potential for automated driving, as they are able to provide large content areas supporting drivers in non-driving related activities. However, it is still unknown how potential drivers or passengers would use these displays. This work addresses user preferences for windshield displays in automated driving. Participants of a user study (N=63) were presented two levels of automation (conditional and full), and could freely choose preferred positions, content types, as well as size, transparency levels and importance levels of content windows using a simulated “ideal” windshield display. We visualized the results in form of heatmap data which show that user preferences differ with respect to the level of automation, age, gender, or environment aspects. These insights can help designers of interiors and in-vehicle applications to provide a rich user experience in highly automated vehicles.
- KonferenzbeitragAutoWSD: Virtual Reality Automated Driving Simulator for Rapid HCI Prototyping(Mensch und Computer 2019 - Tagungsband, 2019) Riegler, Andreas; Riener, Andreas; Holzmann, ClemensHuman factors research in automated driving is nowadays often conducted using either low-quality setups such as 2D monitors or highly expensive driving simulators with motion platforms. Additionally, software for automated driving scenarios is often expensive and hard to modify for different scenarios. We intend to bridge this gap by proposing a low-cost, high-fidelity immersive prototyping solution by utilizing the recent advances in development of virtual reality (VR): AutoWSD - Automated driving simulator for research on windshield displays. We showcase a hybrid software and hardware solution that is based on the popular and widely used Unity development platform. Furthermore, we demonstrate the little effort needed to create scenarios for user studies, and thereby foster discussion about potential improvements and extensions for AutoWSD, as well as the topic of trust, acceptance, user experience and simulator sickness in automation.
- WorkshopbeitragWorkshop on Mixed Reality Applications for In-Vehicle Experiences in Automated Driving(Mensch und Computer 2021 - Workshopband, 2021) Riegler, Andreas; Riener, Andreas; Holzmann, ClemensWith the increasing development of mixed reality (MR), the number of its purposes and applications in vehicles increases. Mixed reality may help to increase road safety, allow drivers to perform nondriving related tasks (NDRTs), and enhance passenger experiences. MR can also be helpful in the transition towards automated driving. However, there are still a number of challenges with the use of MR when applied in vehicles, and also several human factors issues need to be solved. Additionally, virtual reality (VR) has the potential to simulate mixed reality applications for HCI research, such as pedestrian and passenger experiences. In a schedule tailored to fit the requirements of a hybrid presence and online event, participants will define relevant user stories and use cases and elaborate experimental designs with measurable outcomes to contribute to the research roadmap.
