3.1.3 Dialogue Manager
Provider
Design: INRIA and all partners, implementation: SIT
Introduction
The dialogue manager shall facilitate the work of the application developer by proposing
common mechanisms to access and control the fundamental user interface services (e.g.
automatic speech recognition, gesture recognition, GUI) as well as the more advanced user
interface services (e.g. multi-device service, context-driven user interactions).
In the context of ambient intelligence, it shall further provide and use contextual information
that could be used, for example to trigger new applications. Hence, both explicit and a number
of implicit interactions can be handled by the dialogue manager.
As the precise functionalities of future interaction services can not be known in advance, the
architecture of the Dialogue Manager shall also be very flexible so that these new future
services can be easily integrated. Therefore, we have chosen to base the Dialogue Manager
on the blackboard design pattern, as described in the following sections.
The PEGASUS framework enables applications to interact using the blackboard design
pattern. This framework provides the basis for the Amigo service Dialogue Manager that
allows arbitrary Amigo components to interact with Amigo’s various user interface services.
