    The DAUX Framework: A Need-Centered Development Approach for User Experience in Driving Automation
    (2020) Frison, Anna-Katharina
    The 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.
