3.4 Application State Definitions - mmig/mmir GitHub Wiki

Application State Definitions (www/config/statedef)

This directory contains the SCXML (State Chart XML) definitions for the DialogManager and the InputManager (see also Expand Dialog Description (SCXML)).

The InputManager receives the "raw" input events, e.g. touch-events and speech-input-events. These "raw" events are then "translated" into "meaningful" application events, e.g. by fusing multiple events (i.e. multimodal events) or by applying some additional pre-processing. Then the "meaningful" events are raised in the DialogManager affecting the state of the application, e.g. transitioning to another view, or outputting a voice-prompt.

At the core, SCXML documents describe states and transitions between states. The following examples illustrate the basics (for more details see the SCXML specification).
