User Acceptance of Fully Autonomous Public Transport.

The development of fully automated vehicles is becoming more and more present in the social discussion. The image of fully automated cars is determined by automobile manufacturers and placed in the context of individual traffic. In contrast to fully autonomous private cars, fully automated public transport is already operating in some cities and is to be expanded in the future. Autonomous public transport offers great potential for the development and promotion of sustainable mobility concepts. However, the user acceptance is important for the enforcement and widespread use of these technical innovations. An online study on the acceptance of fully automated public transport based on quantitative data of a sample of N = 201 is presented. The results show a high level of familiarity with the topic and a very high level of overall intention to use fully automated public transport in the future.

The Users' Perspective on Autonomous Driving - A Comparative Analysis of Partworth Utilities.

Digitisation has brought a major upheaval to the mobility sector, and in the future, self-driving cars will probably be one of the transport modes. This study extends transport and user acceptance research by analysing in greater depth how the new modes of autonomous private cars, autonomous carsharing and autonomous taxis fit into the existing traffic mix from todays perspective. It focuses on accounting for relative added value. For this purpose, user preference theory was used as a base for an online survey (n=172) on the relative added value of the new autonomous traffic modes. Results show that users see advantages in the autonomous modes for driving comfort and time utilization whereas, in comparison to conventional cars, in many other areas – especially in terms of driving pleasure and control – they see no advantages or even relative disadvantages. Compared to public transport, the autonomous modes offer added values in almost all characteristics. This analysis at the partwor th level provides a more detailed explanation for user acceptance of automated driving.

Mehrwerte auf Basis digitaler Kassenzettel: eine verbraucherinformatische Studie

Die Digitalisierung aller Lebenswelten wird das Kauf- und Konsumverhalten von Verbrauchern stark andern. Es zeichnet sich ab, dass Zukunftsszenarien des Smart Shopping, Smart Kitchen und Smart Cooking zunehmend real werden und sich immer starker verzahnen. Zurzeit finden sich z. B. Bestrebungen zum digitalen Kassenzettel. Der Beitrag zeigt, dass Verbraucher sich hierdurch eine Reihe von Mehrwerten erhoffen, z. B. dass sie eine hohere Transparenz ermoglichen, indem sie Zusatzinformationen zu den Produkten bereitstellen. Ebenfalls sollen die Informationen genutzt werden, Rezeptvorschlage zu den gekauften, im Haus befindlichen Waren sowie Auskunft uber den Zustand der Waren bereitzustellen. Ein weiterer Bereich stellt eine bessere Kosten- und Ernahrungskontrolle dar, indem die Daten des Kassenzettels automatisch in digitale Haushaltsbucher und Ernahrungs- bzw. Fitness-Apps ubertragen werden konnen.

Dealing with Personal Data in the Age of Big Data Economies

The technological development of the digital computer and new options to collect, store and transfer mass data have changed the world in the last 40 years. Moreover, due to the ongoing progress of computer power, the establishment of the Internet as critical infrastructure and the options of ubiquitous sensor systems will have a dramatic impact on economies and societies in the future. We give a brief overview about the technological basics especially with regard to the exponential growth of big data and current turn towards sensor-based data collection. From this stance, we reconsider the various dimensions of personal data and and market mechanisms that have an impact of data usage and protection.

Second Dashboard: Information Demands in a Connected Car

Traditionally automotive UI focusses on the ergonomic design of controls and the user experience in the car. Bringing networked sensors into the car, connected cars can provide additional information to car drivers and owners, for and beyond the driving task. While there already are technological solutions, such as mobile applications commercially available, research on users’ information demands in such applications is scarce. We conducted four focus groups to uncover what kind of information users might be interested in to see on a second dashboard. Our findings show that besides control screens of todays’ dashboards, people are also interested in connected car services providing context information for a current driving situation and allowing strategic planning of driving safety or supporting car management when not driving. Our use cases inform the design of content for secondary dashboards for and especially beyond the driving context with a user perspective.
