Over the past few years we have been developing an expressive embodied conversational
agent system. In particular, we have developed a model of multimodal behaviours that …

There has been rapid development in conceptions of the kind of database that is needed for
emotion research. Familiar archetypes are still influential, but the state of the art has moved …

Automatic recognition of emotion is becoming an increasingly important component in the
design process for affect-sensitive human-machine interaction (HMI) systems. Well …

The performance of an automatic facial expression recognition system can be significantly
improved by modeling the reliability of different streams of facial expression information …

This paper presents the SEMAINE API, an open source framework for building emotion‐
oriented systems. By encouraging and simplifying the use of standard representation …

Imagine you start a conversation with the newest socially interactive agent (SIA), a
humanoid robot or life-size embodied virtual agent. It talks to you and you talk back, but the …

The objective to develop more human-centred, personalized and at the same time more
engaging speech-based interactive systems immediately leads to the metaphor of an …

We present an algorithm for generating facial expressions for a continuum of pure and
mixed emotions of varying intensity. Based on the observation that in natural interaction …

We propose an architecture of an embodied conversational agent that takes into account
two aspects of emotions: the emotions triggered by an event (the felt emotions) and the …

One of the challenges of designing virtual humans is the definition of appropriate models of
the relation between realistic emotions and the coordination of behaviors in several …
