The present work deals with the user-centered design process and its impact on technology acceptance of small screen devices for diabetics. The aim of this interdisciplinary work is to conceptualize a compact diabetes management assistant that meets the needs and requirements of its potential users. Moreover, a better understanding of the relationships of technical expertise, domain specificity, diversity and user acceptance should be obtained in relation to medical technology. Another research question deals with the purposeful endowment of acceptance: Can the user-centered design process, when it is accompanied by methods of technology acceptance research, systematically generate products that show more acceptability? How this can be achieved, is demonstrated in this work.

On this journey, an awareness of the major mobility challenges was raised. In future, the intelligent vehicle technologies will represent new solutions for more mobility, safety, and efficiency in road traffic. The aim of this work is to identify and quantify user factors relevant for technology acceptance with a multi-stage empirical procedure. The simultaneous examination of the automation level, the situation, and the context, established that a requirement-oriented mobility must create individual offers with a transparent communication and information strategy.

As humans, we possess inherent physical skills like stereoscopic vision, spatial hearing, and fine grained motor skills. Throughout our history we have developed physical tools that extend and leverage these skills. The PC as important tool of our time, however, has an interface that is not particularly suited to tasks outside the office domain, but we use it to work with various types of media. The aim of this thesis is to create audio playback interfaces that leverage our natural skills.

The benefits of sufficient activity and a balanced diet are well documented. Yet a trend emerges of spending too much time seated in front of a computer, be it at work or home. Life-logging technologies can help to keep track of, such as steps or calories. They can also give reminders and induce more physical activity, e.g., by awarding (virtual) badges. The present thesis investigates perceived barriers and benefits to the use of life-logging to understand the acceptance of these technologies.

Electricity storage systems can help to ensure a stable electricity supply in the context of the energy turnaround. So far, however, little is known about society's requirements for storage infrastructure. This study contributes to closing this research gap by identifying acceptance-relevant topics in the context of municipal electricity storage facilities through empirical surveys and deriving recommendations for the planning of storage infrastructure.

In the course of demographic change, Ambient Assisted Living, kurz AAL, systems offer potential solutions for an aging population with increasing care needs. The acceptance study of AAL systems, taking into account the influencing factors "user", "room" and "technology", shows The type of technology has the greatest influence, indirect sensor technology is currently accepted, even in private rooms. Audio and video surveillance rejected. This applies generically, regardless of user characteristics.

The work pursues a central question: How can technology extend a space? Within this question different points are addressed: How and where can or should this technology become visible and what role do displays play in the visibility of technology? How does a human interact with a space extended by technology and can the space itself be the interface or be perceived as such?

An ever increasing amount of connected devices and systems is being integrated into buildings. However, a fundamental adaption of the interaction style similar to the adaption of mobile apps for smart phones is still missing. Furthermore, traditional applications of building automation technology are usually concerned with security, comfort, and energy efficiency, but many additional opportunities for usage contexts in buildings exist. This thesis describes the development of a smart environment that is fused with smart phones and other computing devices. To achieve this fusion, a variety of input devices are integrated into the environment. This approach enables the environment itself to become the user interface, and depending on the usage context, users may choose the most appropriate way of controlling it. In addition, new applications beyond the traditional themes of building automation are presented.

The present work focuses on a psychological perspective of technology acceptance, considering the users of electronic Health technology, eHealth) in their home environments. The aim is to explore and identify factors that influence a successful interaction and adoption of such medical assistance technology that is meant to support people in an active and healthy aging. A particular attention is directed to the aspect of user diversity. To realize the objectives, a user-centered research approach was applied in an interdisciplinary environment. In this way, the exploration of how to design and adapt ambient systems to the individual concepts and needs could be optimized

The work combines serious games and ambient assisted living as a solution to meet the demographic change. The empirical evaluation of games for physical and cognitive training with younger and elderly focuses on user and system factors and their relationship to performance and acceptance. It shows that serious games are a valuable contribution, but only if certain conditions are considered. Therefore, the book concludes with guidelines that leverage the use of serious games in technology augmented homes.

Active systems in a building have enormous potential in terms of sustainability and comfort. While they are still not very much integrated in early design phases, many building concepts implicitly and strongly rely on such technical systems. Due to the complex configuration of active system components, which is crucial for the success of an installation, most buildings, once erected, are driven far from optimum. When operation starts, programmers of the technical systems, who could optimize, have long left the building.

Protest is an important part of a living democracy and plays a significant role in shaping social challenges. Understanding protest can help to adapt communication recommendations in the context of energy and infrastructure projects and use them as a basis for dialogue. In this thesis, protest is therefore examined empirically and literature-based as a complex phenomenon. A person-centered approach is chosen to identify characteristics of protesters that can be transferred into considerations of appropriate communication options.

In view of demographic change, innovative concepts will be needed in the future for the care of people in need of medical support. Modern medical technology applications offer solution potential for the emerging challenges. Since the attitude of potential users is a critical factor for the successful use of such approaches, this thesis empirically examines different usage parameters from the perspective of future users.

Assistive technology has the potential to make everyday life easier for the aging population. To date, little is known about individual needs in the context of aging and caregiving. Therefore, this thesis investigates the relationship between perceptions of aging and caregiving with the acceptance of assistive technology by comparing individual perspectives in a multilevel, empirical approach and deriving user-specific design and action recommendations.

The use of modern information and communication technologies, shortform ICT, such as eHealth and mHealth applications, bring great potential for improving the health care system. However, the acceptance of digital ICT in Germany has been low so far. Based on four empirical studies, this work contributes to the understanding of acceptance, user diversity and design of digital ICT in health care and offers user-specific design and action recommendations.
