Ebook: Task Models and Diagrams for Users Interface Design: 5th International Workshop, TAMODIA 2006, Hasselt, Belgium, October 23-24, 2006. Revised Papers

We are proud to present the TAMODIA 2006 proceedings. In 2006, the TA- MODIA workshop celebrated its ?fth anniversary. TAMODIA is an obscure acronym that stands for TAsk MOdels and DIAgrams for user interface - sign. The ?rst edition of TAMODIA was organized in Bucharest (Romania) by Costin Pribeanu and Jean Vanderdonckt. The fact that ?ve years later the TAMODIAseriesofworkshopsstillcontinuessuccessfullyprovestheimportance of this research area for the human–computer interaction community! The ?rst workshopaimed at examining how multiple forms of task expressionscan sign- icantly increase or decrease the quality of user interface design. This is still the scope of the current edition; we tried to assemble papers that discuss how the complexity of HCI design and development can be managed with tasks, models and diagrams. Much like the previous editions, the selection of papers from the 2006 edition re?ects the broad scope of this ?eld, which cannot be labeled with a single title or term. The invited paper is by Jo¨ elle Coutaz and discusses meta-user interfaces for ambient spaces. Finding appropriate ways to design and develop user interfaces for interactive spaces is becoming an important challenge for the creation of future usable applications. This exciting work gives a good feel of the new type of user interfaces and the required new approaches we are evolving toward when we want to realize the vision of ambient intelligent environments and create systems that can be used and controlled by the end-users.

This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop on Task Models and Diagrams for User Interface Design, TAMODIA 2006, held in Hasselt, Belgium in October 2006.

The 23 revised full papers presented together with 1 invited paper were carefully reviewed and selected from numerous submissions for inclusion in the book. The workshop focused on different forms of models, diagrammatic and formal notations, and analytic frameworks used to understand human tasks and activities with computers and technology. The papers are organized in topical sections on tool support, model-based interface development, user interface patterns, bridging the gap: driven by models, task-centered design, multi-modal user interfaces, reflections on tasks and activities in modeling, as well as context and plasticity.
