Abstract

Systems and methods for building multi-modal browsers applications and, in particular, to systems and methods for building modular multi-modal browsers using a DOM (Document Object Model) and MVC (Model-View-Controller) framework that enables a user to interact in parallel with the same information via a multiplicity of channels, devices, and/or user interfaces, while presenting a unified, synchronized view of such information across the various channels, devices and/or user interfaces supported by the multi-modal browser. The use of a DOM framework (or specifications similar to DOM) allows existing browsers to be extended without modification of the underling browser code. A multi-modal browser framework is modular and flexible to allow various fat client and thin (distributed) client approaches.

Claims14

Dependent claims

A multi-modal browser, comprising:

a plurality of modality-specific browsers, and
a multi-modal shell that parses and processes a modality-independent representation of an application to generate modality-specific representations of the application which are rendered by corresponding modality-specific browsers to generate modality-specific views of the application, and to manage synchronization of I/O (input/output) events across each modality-specific view,
wherein each modality-specific browser comprises:
an API (application programming interface) that enables the multi-model shell to control the browser and access events;
and
a wrapper interface that support synchronization between the modality-specific views by event filtering and exhchanging synchronization information between the multi-modal shell and the browser,
wherein the multi-modal shell comprises:
a model manager for maintaining a dialog state of the application;
a TAV (transformation/adaption/view preparation) manager for preparing and transforming pages or page snippets;
and
a synchronization manager for managing event notifications to the browsers.
