Designing and developing affective dialogue systems have been receiving much interest from the dialogue research community [1]. Previous work was mainly focused on showing the system's emotion to the user in order to achieve designer's goals such as helping students practice nursing tasks [7] or persuading users to change their dietary behavior [6].

Virtual meeting rooms are used for simulation of real meeting behavior and can show how people behave, how they gesture, move their heads, bodies, their gaze behavior during conversations. They are used for visualising models of meeting behavior, and they can be used for the evaluation of these models. They are also used to show the effects of controlling(More)
A Reactive Virtual Trainer (RVT) is an Intelligent Virtual Agent (IVA) capable of presenting physical exercises that are to be performed by a human, monitoring the user and providing feedback at different levels. Depending on the motivation and the application context, the exercises may be general ones of fitness to improve the user's physical condition,(More)
In current meeting research we see modest attempts to visualize the information that has been obtained by either capturing and, probably more importantly, by interpreting the activities that take place during a meeting. The meetings being considered take place in smart meeting rooms. Cameras, microphones and other sensors capture meeting activities.(More)
In this paper we report about ongoing research on navigation assistance in virtual environments. Our aim is to contribute to the development of forms of navigation assistance that enable non-professional visitors of a virtual environment to find their way without previous training. The environment used in this research is a virtual theatre that models a(More)
