The discipline of software engineering is increasingly shifting from classical design and development tasks towards tasks concerning reuse, adaptation, and integration. Driving motivations for this shift are (i) decreasing development time and costs and (ii) increasing quality of design results. Unfortunately, these new tasks are not yet supported sufficiently. While classical approaches to information system's design are quite well suited to a design from scratch, they do not provide powerful concepts concerning reuse. In particular, methods concerning encapsulation of dialog structures are commonly neglected. An according approach which enables reuse of dialog structures poses substantially different problems. This thesis formalizes such an approach which is essentially based on models from three research areas: (i) interaction patterns, (ii) interaction specification, and (iii) component frameworks.
Today, developers of human-computer interaction increasingly face high expectations regarding the adaptivity of interaction. The World Wide Web is a fitting example for how diverse and 'fickle' the demands on interaction are which users, service providers and even the available technical infrastructure pose. In this thesis, a general framework for the development of interaction for such heterogeneous and dynamic interaction environments is created. The main focus is the provision of abstract constructs which make it possible to specify interaction abstractly, i.e., independently from concrete properties of an individual interaction environment. We then show how such an abstract specification can be used to automatically create human-computer interfaces which - due to the fact that the automatic generation takes the current interaction environment into account - are tailored to the requirements of the current user, technical infrastructure, etc.
