The W3C MMI Working Group suggests the use of SCXML to express the dialog control of multimodal applications. The overall approach has already been shown to be suitable i.e. to decouple the control flow and presentation layer in multimodal dialog systems. It has been used in several applications to express dialog states, control handheld gaming consoles or to easily incorporate information from external systems. With the first implementations of the suite of recommendations beginning to mature, more deployments in industry are starting to appear, e.g. for in-car infotainment systems, home automation and general dialog control. This gave rise to a new set of problems with regard to the operationalization and unveiled short-comings and new requirements we hope to discuss. Despite these rather practical issues, there are still very interesting research questions revolving SCXML and related recommendations. The strong focus on state-charts could enable many formal approaches inapplicable to other dialog management techniques. Automated dynamic and static testing of dialogs expressed in SCXML or even model checking. The workshop provided a forum to discuss submissions detailing the use of SCXML, in particular, multi-modal dialog systems adhering to the concepts outlined by the various W3C standards in general and related approaches of declarative dialog modeling to engineer interactive systems. These proceedings contain the keynote from Jim Barnett and six submissions around the e different aspects of engineering interactive systems with SCXML.
