Class AbstractFloorTracker

java.lang.Object
  inpro.incremental.PushBuffer
      inpro.incremental.IUModule
          inpro.incremental.processor.AbstractFloorTracker

All Implemented Interfaces:

edu.cmu.sphinx.instrumentation.Resetable, edu.cmu.sphinx.util.props.Configurable

Direct Known Subclasses:

IUBasedFloorTracker, TextBasedFloorTracker

public abstract class AbstractFloorTracker
extends IUModule

A floor tracker tracks which dialogue participant has the floor (i.e. the user or the system) and takes decisions when the floor should be taken or released

Nested Class Summary

protected static class	AbstractFloorTracker.InternalState the internal state of the floor tracker: - user is silent and we're not expecting her to speak - user is silent but we are expecting her to speak (this may lead to a time-out) - user is talking (currently no provisions for whether we want her to speak or not)
static interface	AbstractFloorTracker.Listener the interface that the floor manager's listeners must implement
static class	AbstractFloorTracker.Signal other modules are notified about floor state if they implement FloorManager.Listener and are registered to listen in the configuration file
