Adapting applications and user interfaces at runtime requires a deeper understanding of the underlying design. Models formalize this design, express the underlying concepts and make them accessible to machines. In our work we utilize runtime models to reflect the state of the interactive system (its UI respectively) and to change its underlying(More)
Offering user interfaces for interactive applications that are flexible enough to be adapted to various context-of-use scenarios such as supporting different display sizes or addressing various input styles requires an adaptive layout. We describe an approach for layout derivation that is embedded in a model-based user interface generation process. By an(More)
The creation of user interfaces usually involves various people in different roles and several tools that are designed to support each specific role. In this paper we propose a tool for rapid prototyping that allows all parties involved to directly interact with the system under development. The tool is based on task tree development and integrates the(More)
The availability of numerous networked interaction devices within smart environments makes the exploitation of these devices for innovative and more natural interaction possible. In our work we make use of TVs with remote controls, picture frames, mobile phones, touch screens, stereos and PCs to create multimodal user interfaces. The combination of the(More)
Enriched with more and more intelligent devices modern homes rapidly transform into smart environments. Their growing capabilities enable the implementation of a new generation of ubiquitous applications, but also raise the complexity of the development. Developers of applications for smart environments must cope with a multitude of sensors, devices, users(More)
One of the challenges faced by developers of applications for smart environments is the diversity of contexts of use. Applications in smart environments must cope with continuously changing context of use, so the developers need to prepare them for a possibly broad range of situations. Since the developer has no access to all environments, in which her(More)
Runtime models enable the implementation of highly adaptive applications but also require a rethinking in the way we approach models. Metamodels of runtime models must be supplemented with additional runtime concepts that have an impact on the way how runtime models are built and reflected in the underlying runtime architectures. The goal of this work is(More)
