    The application of ubiquitous and social computational systems shows a rapidly increasing trend in our everyday environments: Enhancing social interactions and communication in both online and real-world settings is an important issue in a broad range of application contexts. This chapter describes the development of ubiquitous and social software for enhancing social networking. The Connect-U demonstrator features a class of such applications. In particular, it comprises the Conferator and MyGroup applications for enabling smarter social interactions in the context of conferences and working groups. We describe the applied socio-technical design process, and discuss experiences and lessons learned.

    Ubiquitous applications are complex systems, and need to be evaluated with respect to their social compatibility in an encompassing and interdisciplinary approach. Interdisciplinary work bears the challenge of maintaining the strengths and specialities of each discipline while yielding consistent results at the same time. Also, the evaluation should be well-matched with other activities in the process of development. The presented system evaluation is designed to fulfill these goals as part of the VENUS Development Method . The system evaluation brings a development circle to a conclusion, and generates consistent results that facilitate decisions for next steps. The evaluation also yields suggestions for possible, further improvements. System evaluation unites four disciplines: usability engineering , trust engineering , legal compatible technology design , and security analysis . This chapter describes the starting points of each discipline, and derives an interdisciplinary approach which encompasses a concerted operating plan as well as contentual interdisciplinary cooperation. The system evaluation provides joint solutions for empirical work, but also leaves room for disciplinary analyses.

    The acceptance of ubiquitous systems differs between individuals. This chapter presents research results on this topic in the form of a user model that systematically describes the influence of personality factors on the acceptance of Ubiquitous Computing (UC). In addition to the traditional factors of acceptance, trust and the perceived legal certainty are considered in the model. The result connects user characteristics with the determinants of the acceptance for UC. The findings are based on surveys conducted with the application Meet-U . Potentialities for using the results to design acceptable applications are derived.
