This thesis explored the design space and possibilities of stereoscopic 3D dashboards. Important problems that have been and will be a challenge in the automotive domain, guided the research process. Our results provide insights in these very domains — driver distraction, trust, and take-over process — but also open up new application domains.
Chapter
In SAE level 3 automated vehicles, the human driver still needs to be ready to take over control in case the vehicle encounters a situation outside its operational design domain. This chapter outlines a case study where smart stereoscopic 3D icons act as a take-over notification.
Chapter
When driving manually, people often have to react to stimuli on the dashboard, for example flashing warning signs on the instrument cluster. Also, many applications in the vehicle are structured as text-based, hierarchical menus. For example, the entertainment or the navigation system. When executing such tasks, the user is distracted and cannot fu...
Book
Over the last decades, the interior of cars has been constantly changing. A promising, yet unexplored, modality are large stereoscopic 3D (S3D) dashboards. Replacing the traditional car dashboard with a large display and applying binocular depth cues, such a user interface (UI) could provide novel possibilities for research and industry. In this bo...
Conference Paper
Many virtual reality (VR) applications rely on passive haptics where virtual objects have a real counterpart that provides tactile feedback. In addition to that, many VR applications do not provide accurate hand representations, especially when there is a high chance of occlusion as this makes vision-based tracking problematic. Hence, we investigat...

When operating a conditionally automated vehicle, humans occasionally have to take over control. If the driver is out of the loop, a certain amount of time is necessary to gain situation awareness. This work evaluates the potential of stereoscopic 3D (S3D) dashboards for presenting smart S3D take-over-requests (TORs) to support situation assessment...
Conference Paper
In recent years, stereoscopic 3D (S3D) displays have shown promising results on user experience, for navigation, and critical warnings when applied in cars. However, previous studies have only investigated these displays in non-interactive use-cases. So far, interacting with stereoscopic 3D content in cars has not been studied. Hence, we investigat...

Zunächst soll kurz auf den eigentlichen Autorenprozess eingegangen werden, bevor ausgewählte Autorenwerkzeuge für VR und AR betrachtet werden. Anschlie...
Conference Paper
Calling while driving poses a severe safety risk. When more than two people are involved in a call-a conference call-this risk increases even more. Intelligent vehicles could offer support systems that ease the cognitive burden of such a multiparty calls. We explore the possibilities of such advanced driving assistant systems (ADAS) in two ways: fi...
Conference Paper
Trust in self-driving cars is considered to ensure appropriate usage of such vehicles. Representing the automation system as an anthropomorphic virtual assistant that communicates the system's behavior could help to build and maintain trust. To explore such assistants, a prototype of an anthropomorphic virtual assistant was designed and integrated...

The ongoing digitalization of our world also offers an increasing amount of information to the human. To present this data to a driver, visualization strategies are necessary going beyond traditional displays. In this paper we investigate the effect of stereoscopic 3D (S3D) visualization and the influence of the S3D contents’ locations on the dashb...
Conference Paper
In the sharing-economy, users do not necessarily own a car but use commercial services to rent a car according to their needs, requirements, and liking. To provide the best driving experience and safety, it is necessary that they understand the car and its functionality. Assuming that future vehicles will facilitate mostly screens for information p...

As a part of the Exzellenzinitiative, a Federal program supported by the Free State of Thuringia, the ProExzellenz-Zentrum VISTA4F captures contemporary social issues accompanied by the megatrends mobility, energy, security and environment. The interdisciplinary research on these issues is conducted from the intertwined perspectives of automotive engineering, information technology, media technology and communication science. Connecting diverse types of electromagnetic, mechatronic, audiovisual, psychological and physiological measurements and presentation platforms, the project aims at designing and implementing a virtual testing and simulation environment to be deployed in automotive and transport development. At VWDG, we investigate how a virtual cockpit can look like. Using Augmented Reality and Virtual Reality, we research novel AR-based advanced driver assistance systems, 3D in-car user interfaces, and stereoscopic in-car visualizations.
