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.

Software development for the automotive domain is currently subject to a silent revolution. On the one hand, software has become the enabling technology for almost all safety-critical and comfort functions o?ered to the customer. A total of 90% of all innovations in automotive systems are directly or indirectly - abled by software. Today's luxury cars contain up to 80 electronic control units (ECUs) and 5 di?erent, inter-connectednetworkplatforms, overwhich some700 software-enabled functions are distributed. On the other hand, the complexity induced by this largenumber of functions, their interactions, and their supporting infrastructure has started to becomethe limiting factor for automotive software development. Adequate management of this complexity is particularly important; the following list highlights three of the corresponding challenges: First, the dependencies between safety-critical and comfort functions are rapidly increasing;a simple example is the interplay of airbag controland power seat control in the case of an accident. Careful analysis and design of these dependencies are necessary to yield correct software solutions. Second, advances in wired and wireless networking infrastructures enable - terconnection between cars and backend service providers (e.g., to call for help in cases of emergency), between cars and devices brought into the car by drivers and passengers (such as cell phones, PDAs, and laptops), and even among cars. This dramatically shifts the focus from the development of individual software solutionsresidingondedicatedECUstotheirdistributionandinteractionwithin and beyond car boundaries.
