For example, the fact that such vehicles might operate independently (without a human driver) creates a barrier of uncertainty and mistrust among people. In this work, we aim to identify and classify the prevailing reservations and propose solutions. We followed the User Centered Design (UCD) process to design concepts that are specifically tailored to the needs of future public transport users. After related work analysis, on-site research, and pre-studies, two main studies were conducted specifically to address communication in the exterior (n = 24) and interior/service design (n = 21). For both studies, we applied a mixed-methods approach combining quantitative and qualitative measures. Our results indicate that, in general, existing ways of communication in the exterior are insufficient to meet future needs. The two visualization concepts for external communication developed in this work were rated (significantly) better in most dimensions of the User Experience Questionnaire (UEQ), when compared to the baseline condition with no additional visualization. Furthermore, preferences among the study participants towards simple, highly visible, and well-known lighting concepts could be observed. As for the interior, the results show that participants rated attractiveness highly for the two design concepts (closer, further in the future) as compared to current, state-of-the-art solutions (automated buses currently in operation). For the “near future” concept, the pragmatic quality dominated, while in the other (the “far future”) concept the hedonic quality was in the foreground. From the results, design recommendations in different categories were derived, which reflect the general openness of the public towards new technologies and interior approaches, but also point out the importance for privacy and designated personal spaces inside an (automated) shuttle bus. Some of the results do not strictly apply to automated shuttle buses, and can serve as valuable suggestions for improving conventional shuttle buses.

It focuses on the semiotic and sensory perception fields. The purchase of fully automatic espresso machines is an investment for customers, therefore the perceived quality plays a special role within this product category. Design has the capability to enhance the perceivable quality of a product besides the classic unterstanding of quality management. The central questions to be answered in the course of this work were as follows: How do users interpret quality in the context of fully automatic espresso machines? What are the factors that influence this impression of quality? Which of these factors have the greatest influence? How can these be adjusted by designers to enhance the perceived quality? The thesis defines and structures perceived quality levers of fully automatic espresso machines for use in the design process. The entire process is carried out according to the User-Centered Design approach (UCD). In order to acquire basic knowledge on the subject of perceived quality, the basics are dealt with at the beginning and research is carried out in these areas. After an extensive analysis with expert and user interviews, the relevant product dimensions were identified. Further the target group with specific charactersitcs, needs and expectations was defined. The examination and structuring of the defined product attributes and components, according their influence on the perceived quality, were done in a pre-study. Following an in depth elaboration of the most relevant parameters was conducted in the main study to derive design recommendations. The final research results are presented in a theoretical guideline and in a multi-sensorial experience model. The key findings of the work show that the perceived quality of fully automatic espresso machines is strongly influenced by its material, finish and colour. The control unit and the front area are components that must be prioritised for a fully automatic espresso machine. Perceived quality in general is very context dependent and must always be considered specifically. By precisely defining the product structure with components and relevant factors, the potential for improving the perceived quality of each product can be approached.
