Two New Modalities for ARIA

Accessibility of rich internet applications is ensured by ARIA and assistive technology supporting this additional mark-up. We propose MM-ARIA for the integration of multiple types of assistive technology while supporting multimodal interaction. The Dojo toolkit’s calendar widget is an example of a complex, non-standard widget requiring ARIA mark-up. MM-ARIA generates grammars for speech recognition and integrates gestural input for navigation in the calendar or selecting an item. MM-ARIA relies on multimodal mark-up language EMMA and an interpreter for parallel input. Our proof-of-concept application demonstrates the extensibility of widgets described by ARIA.
