================================================================== Use In Context Between adaptivity and adaptation in context-based interactions

Workshop at the Informatik 2008 September 12, 2008 Munich, Bavaria, Germany http://kalu.fernuni-hagen.de/Informatik2008/

Submission deadline: April 28, 2008 ==================================================================

Context-based systems slowly emerge from research settings to usage practice. Consequently, next to questions dealing with the technological feasibility, questions dealing with the manageability and transparency of context-based services from a user perspective come to the fore. In particular, ubiquitous computing applications help bridging between virtual and real-world context dimensions (both, concerning virtual and real context sensors and virtual and real context factors). The resulting system often remains intransparent to users, it is not immediately accessible recurring on conventionalized behavioural practices.

This workshop aims to contribute on the one hand to the collection of use-oriented problems in context-based interaction. Furthermore, we aim to discuss resulting implications regarding the technical design of interfaces as well as soft- and hardware architectures. Special attention is given to context modeling and implementation of the various application scenarios as well as to the associated possibilities of manual (adaptability) or automatic (adaptivity) in-use-adjustment. A further special area of interest within a user-oriented perspective is the understanding of problem dynamics in scenarios with multiple-context systems and –technologies, and problem dynamics of emergence or evolution of context-based systems.

We would like to invite in particular researchers and practitioners to contributions dealing with the following questions:

- What practical experiences – positive as well as negative – have been made with regard to the usage of context-based systems in real organizational settings? What experiences have been made with adaptation mechanisms (automatic as well as interactive) of such systems in these settings?

- How can relations between context descriptions/models, context sensors and context-based services become describable in a way that they can be inform end users? What framing conditions apply for interfaces that aim to achieve this?

- What experiences have been collected with ontologies and folksonomies? How can systems be designed more practice-oriented?

- How can context architectures be effectively designed for sustainable usages (Context evolution, context adaptation, traceability for end-users)?

- How do architectures look like that are appropriate for the realization of context-adaptive systems that remain modifyable in-use? What services have to be provided by such a context-adaptive system? What interfaces are needed for a context-dependent adaptation of the system behavior?

The contributions should derive out of various application areas, such as - Context-based Information Retrieval - Location-based Services - Mixed-Media Environments - Tagging Systems, other Semantic Web Applications - Mobility Services - Knowledge Management and Knowledge Media Creation - Community Applications

We request for contributions to those topics in relation to research as well as practice.
