    Software development has proven to be a challenge. To address this challenge, there are quite many interesting approaches how to develop software - starting from the waterfall approach, up to recently quite popular agile software development techniques. Another already some years old approach was described by the Gang of Four and proposes the usage of design patterns to provide a general reusable solution to commonly occurring problems in software development. Although design patterns have been around for a long time, their usability is still promising. To the best of our knowledge ”interdisciplinary patterns” to address challenges in the development of context aware application in ubiquitous environments have not been described in literature so far. Hence, this paper proposes and also evaluates concrete interdisciplinary software development patterns. To provide an application example the proposed patterns are used to address two use cases that commonly occur in the development process of context aware applications: providing transparency to the user and ensuring a user's self-determination. For the demonstration of the patterns Support-U a context aware application that provides elderly people to live autonomously is used.

    Socially acceptable design of a ubiquitous system for monitoring elderly family members
    (INFORMATIK 2012, 2012) Hoberg, Sebastian; Schmidt, Ludger; Hoffmann, Axel; Söllner, Matthias; Leimeister, Jan-Marco; Voigtmann, Christian; David, Klaus; Zirfas, Julia; Roßnagel, Alexander
    Some functions in ambient assistance systems are enabled by sensors gathering data from the surroundings. While many prototypes are developed to prove technical concepts, for creating an acceptable, usable product additional facets need to be considered. Therefore, we present an approach to develop a functional ubiquitous system to support the monitoring and assistance of elderly family members. Besides the necessary technical concepts, insights from trust, law and user interface design are incorporated in this approach. The main idea of the approach is to deduce functional requirements from normative guidelines, theories or laws, and to combine the contributions from the involved disciplines developing the Senior Monitor demonstrator.
