This book constitutes the refereed proceedings of the 6th International Workshop on Task Models and Diagrams for User Interface Design, TAMODIA 2007, held in Toulouse, France, in November 2007. The 16 revised full and 7 revised short papers presented together with 1 keynote paper and 2 industrial papers were carefully reviewed and selected from numerous submissions for inclusion in the book. The workshop features current research and gives some indication of the new directions in which task analysis theories, methods, techniques and tools are progressing. The papers are organized in topical sections on extending task models, model-driven engineering, task-based evaluation and testing, task patterns, workflow based systems.
