Multimodal Interaction Use Cases

The W3C Multimodal Interaction Activity is developing specifications as a basis for a new breed of Web applications in which you can interact using multiple modes of interaction, for instance, using speech, hand writing, and key presses for input, and spoken prompts, audio and visual displays for output. This document describes several use cases for multimodal interaction and presents them in terms of varying device capabilities and the events needed by each use case to couple different components of a multimodal application.
