Workshop on using Ink in Multimodal Applications within the W3C's Multimodal Architecture and Interfaces

Due to limited participation caused by the influenza pandemic the workshop on using Ink in Multimodal Applications within the W3C's Multimodal Architecture and Interfaces has been canceled.

10-11 July 2009

Hosted by the University of Western Ontario

This W3C Workshop is taking place right after the third International Workshop on Pen-Based Mathematical Computation (PenMath2009) during the meeting week of the Conferences on Intelligent Computer Mathematics (CICM 2009) in Grand Bend, Ontario, Canada.


The W3C Multimodal Interaction Working Group seeks to extend the Web to allow users to dynamically select the most appropriate modes of interaction for their current needs, including (a) needs of the specific users (e.g., users with disabilities) (b) across interactions (e.g., use keyboard instead of speech in a noisy environment) and (c) within interactions (e.g., speak a command and point to select the object of the command). Multimodal modes of input are especially important for devices with small displays and small or nonexistent keypads.

To achieve that purpose, the group is working hard on the following Multimodal specifications.

MMI Architecture
The Multimodal Architecture and Interfaces (MMI Architecture) specification is designed to provide a general and flexible framework providing interoperability among modality-specific components from different vendors - for example, speech recognition from one vendor and handwriting recognition from another.
MMI Authoring
The group provides Authoring Applications for the Multimodal Architecture (MMI Authoring) including examples of MMI application implementation to (1) clarify how to implement multimodal applications based on the architecture and other existing W3C specifications and (2) suggest standard approaches, techniques and principles for developing multimodal user interfaces on mobile phones in particular as well as other devices.
Extensible Multi-Modal Annotations (EMMA) is a data exchange format for the interface between different levels of input processing and interaction management in multimodal and voice-enabled systems. It provides the means for input processing components, such as speech recognizers, to annotate application specific data with information such as confidence scores, time stamps, and input mode classification (e.g. key strokes, touch, speech, or pen).
Ink Markup Language (InkML) is an XML language for ink traces which provides a range of features to support real-time ink streaming, multi-party interactions and richly annotated ink archival. Applications may make use of as much or as little information as required, from minimalist applications using only simple traces to more complex problems, such as signature verification or calligraphic animation, requiring full dynamic information.

In order to make the above Multimodal specifications, especially InkML as a language for handwriting recognition, more useful in current and emerging markets, the Multimodal Interaction Working Group is interested in suggestions on how to improve the use of InkML in multimodal applications within MMI Architecture to support and integrate various user interfaces on multimodal devices, e.g., PDA, mobile phones and other handheld devices.

Workshop Goals

The goal of this workshop is to identify and prioritize requirements for changes, extensions and additions to Ink standards especially in Multimodal Applications developed based on the W3C's MMI Architecture as a means of making InkML more useful in current and emerging markets.

The workshop will discuss the following three questions:


The workshop will produce a document that will:

Scope of the Workshop

This workshop is focused on Ink in multimodal applications within MMI Architecure. The scope of this workshop is restricted in order to make the best use of participants' time. In general, discussion at the workshop and in the position papers should stay focused on the workshop goal. Descriptions of new requirements with usage scenarios and clear explanations of the problems to be solved is of top priority for the workshop, while examples of Ink syntax extensions is secondary priority.

Attendees does not have to be familiar with the MMI Architecture but expertise on Ink technology is expected.

Expected Participants

We expect several communities to contribute to the workshop:

Requirements for Participation

Position papers are required to participate in this workshop. Each organization or individual wishing to participate must submit a position paper by the date shown below. Participation is pending acceptance of the position paper by the program committee.


Possible topics include, but are not limited to the following:

Position Papers

Position papers will be the basis for the discussion at the workshop. Papers should explain the participant's interest in the workshop, explain their position and include concrete examples of their suggestions. Position papers must be written in English. Examples in non-English languages are acceptable, but English explanation must be added.

Position papers should be written in in English. Examples may be illustrated with non-English languages with an English explanation. All papers should be 1 to 5 pages, although they may link to longer versions or appendixes. Allowed formats are (valid) HTML/XHTML, PDF, or plain text. Papers in any other formats (including invalid HTML/XHTML) will be returned with a request for correct formatting.

Papers must be submitted by email to member-mmiws-submit@w3.org before 1 June 2009.

Accepted position papers will be published on the public Web page of the workshop. Submitting a position paper comprises a default recognition of these terms for publication.

The Program Committee may ask the authors of particularly salient position papers to explicitly present their position at the workshop to foster discussion. Presenters will be asked to make the slides of the presentation available on the workshop home page in HTML, PDF, or plain text.

See the schedule below for submission and registration deadlines.
