Engineering Interactive Systems with SCXML

Workshop in conjunction with EICS 2014,
Rome, Italy June 17, 2014


The W3C is about to finalize the Statechart Extensible Markup (SCXML) standard to express Harel state-machines as XML documents. In unison with the W3C MMI architecture specification and related work from the W3C MMI working group, this recommendation is a promising candidate to become the "HTML of multi-modal applications".

Workshop Topics

The workshop will provide a forum to discuss submissions detailing the use of SCXML in particular. More generally, multi-modal dialog systems adhering to the concepts outlined by other W3C standards will be covered, as well as related approaches to declarative dialog modeling.

We invite submissions in three different formats:

All submissions will be peer-reviewed. Besides based on general contributions, submissions will also be selected on their potential to initiate discussion. Accepted submissions will be made available as online proceeding on our web site. Moreover, they will be made available on our publication server to ensure that they can be cited. Copyright is retained by the authors thus papers can be submitted for other venues that allow this.

We are also planning for a special issue on SCXML in the Journal on Multimodal User Interfaces. Authors of selected papers will be invited to submit extended versions for the special issue.


All submissions have to be

  1. prepared according to the HCI Archive Format and
  2. submitted in PDF format through the workshop management system at EasyChair.
