Summary of the May 25-27 face to face meeting of the W3C Multimodal Interaction Working Group

The W3C Multimodal Interaction (MMI) Working Group [1] held a face to
face meeting in Berlin, Germany, May 25-27, hosted by T-Systems,
following a meeting of the Voice Browser Working Group [2].  Thanks to
T-Systems for their excellent logistical arrangements and support.  

This note summarizes the results of the meeting.

The May 25 agenda included a joint meeting with the Voice Browser
Working Group and representatives of the OMA [3], who provided us with
information on their architecture and also with some preliminary
feedback on the MMI architecture [4]. We plan to continue exchanging
feedback as our respective architectures mature.

There were 20 attendees from 15 organizations at the main MMI meeting,
May 26-27.

The main topics of discussion were MMI architecture, analysis of
VoiceXML 2.1 [5] as an example of a speech modality component, and
EMMA [6].

In our analysis of VoiceXML 2.1 as an example of a speech modality
component, we focused on issues of synchronization of information and
focus among modalities and considered serveral different approaches.
In the architecture discussion we continued working on the next
version of the MMI Architecture WD including issues such as
requirements for the MMI container, whether MMI documents should have
one DOM and the eventing model.

In order to create specific examples of the MMI architecture in use we
also analyzed the driving directions use case from the MMI
architecture specification [7] using three different approaches -- the
state machine based markup currently being developed by the Voice
Browser Working group [8], rule-based systems, and scripting.

We reviewed the status of EMMA and expect to publish the Last Call
Working Draft in early July, following a final determination of
optional and obligatory features and an update to the XML Schema.

The next Multimodal Interaction Working Group meeting will be held in
Toronto, Canada, September 19-20, 2005, hosted by Voice Genie.

Best regards,

Debbie Dahl, MMI Working Group Chair
