W3C Multimodal Interaction Framework

This document introduces the W3C Multimodal Interaction Framework, and identifies the major components for multimodal systems. Each component represents a set of related functions. The framework identifies the markup languages used to describe information required by components and for data flowing among components. The W3C Multimodal Interaction Framework describes input and output modes widely used today and can be extended to include additional modes of user input and output as they become available.
