The adaptation of systems to its environment in general or its users in particular became a gained more and more research interest over the last year. The approaches range from explicit user modeling over data mining approaches with no explicit model and include real time adaptation to non-persistent user features or to changing contexts. The range of application fields for adaptive systems is spreading enormously and reaches meanwhile everybody’s daily life in the form of washing machines which automatically adapt their program to their content or driving assistants, which adapt to the drivers (or other drivers’) behavior, e.g. Also, the scientific roots of the approaches are very diverse and originate from different scientific communities such as “Human Factors of Software Systems”, “Man-Machine Communication”, “Artificial Intelligence” and “Data Mining”. An interdisciplinary workshop with researchers of such different backgrounds opens the chance to learn from each other and to refine the own approach accordingly.
