2nd Workshop on
Engineering Interactive Systems with SCXML

Workshop in conjunction with EICS 2015,
Duisburg, Germany June 23rd, 2015


The W3C SCXML standard for Harel state-charts, in unison with the W3C MMI architecture specification and related work from the W3C MMI working group are a promising suite of recommendations to become the ``HTML of multi-modal applications''. This 2nd installment of the workshop will provide a forum for academia and industry alike to discuss recent developments with regard to dialog modeling using state-charts and identify remaining short-comings in the operationalization and application of the related approaches.

Workshop Topics

The workshop will provide 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.

Time Activity Persons
9:00am Welcome Note Stefan Radomski
9:10am Invited Talk "Current Status and Future Prospects" [Slides]

After an overview of the current status of the SCXML standard, this talk will focus on work that could be done after 1.0. Obvious candidates include new plug-ins (e.g., DOM Event I/O Processor or other event I/O processors data models), modifications to the core language (e.g., pluggable pre-emption logic), and relations with other languages (VXML or rule-based systems.) I will cover the W3C fora that are available for this work, but it may be best to let implementers experiment on their own until consensus emerges on what changes are needed.

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.


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.
