- DissertationThe DAUX Framework: A Need-Centered Development Approach for User Experience in Driving Automation(2020) Frison, Anna-KatharinaThe individual and societal benefits of driving automation can only unfold if the underlying technology is established on the market. As user acceptance is dependent on users' experience with a technology, i.e. user experience (UX), novel user interfaces (UIs) need to be developed to balance drawbacks of individual automation levels (SAE J3016). Therefore, the predominant innovation- and technology-centered perspective has to be supplemented by a user-centered approach. As a solution, the "DAUX Framework", as part of a need-centered development approach, is proposed. The framework offers guidelines how to a) identify relevant needs for hypothesis/ UI concept development and b) evaluate UX by triangulating behavioral, product-, and experience-oriented methods. To derive recommendations for UI development, the introduced approach is applied in three case studies. Thereby, example UIs for different levels of automation are developed (SAE L2, L3, and L4/5) and then evaluated in a high-fidelity driving simulator. Results about partial driving automation (SAE L2) imply, all properties of an automated vehicle, also usability and aesthetics of an embedded UI, wrongly impact drivers' fulfillment of the need of security. Hence, the current system performance must always be transparent. A safe trip is the basis of positive driving experiences. Further, skipping the launch of conditional driving automation (SAE L3) is not only justifiable from safety, but also from experiential perspective. Results show that due to users' needs for autonomy, competence, and security, the mere possibility of a take-over-request at any time negatively impacts the whole journey experience. At high and full driving automation (SAE L4/5), users worry about their needs of competence, autonomy, and the meaning of driving interactions, e.g., accelerating. Although engaging in non-driving related tasks might balance these problems, there will still be users who appreciate the joy of driving. Hence, optional control should always be offered. The "DAUX Framework", as part of a need-centered development approach, has been applied in different use cases and has proven to be a valid and useful approach for developing UIs to improve UX for driving automation. Consequently, this PhD work supports - by appropriate design and development of UIs - the individual and societal acceptance of the technology of driving automation. This work lays the foundation that promised advantages can be realized.
- WorkshopbeitragDesigning Interfaces for Elastic Displays Using Workshop and Prototyping Methods(Mensch und Computer 2021 - Workshopband, 2021) Hannß, Franziska; Müller, Mathias; Kammer, DietrichAny design endeavor requires practitioners to engage in divergent thinking (cp. Double Diamond Model). Numerous creativity techniques and methods exist to support the design process and give structure in order to converge a wide variety of ideas into suitable candidates for prototyping and testing. Designing for specific, tangible interaction technologies requires a careful framing of the selected methods. Over the course of 10 years, our research group has gained experience in designing and developing applications for elastic displays. In this pictorial paper, we illustrate methods and intermediate results for a concrete application design. Due to the Covid19 pandemic, we made extensive use of the collaborative whiteboard application miro. We designed a way to visualize, explore, and evaluate clustering algorithms in the domain of machine learning using an elastic display. Finally, we present follow- up techniques for prototyping the concepts and ideas.
- WorkshopbeitragIntermodal personalized Travel Assistance and Routing Interface(Mensch & Computer 2014 - Tagungsband, 2014) Schaffer, Stefan; Reithinger, NorbertAn increasing amount of available data sources and intermodal travelling pose a challenge for the design of mobility apps. This paper examines the concept of an interface for intermodal personalized travel assistance and routing. The analysis of two central use cases intermodal routing and personalization revealed pitfalls and gaps for the design of mobility apps.
