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 expressed emotions (the displayed ones), which may differ in real life, In this paper, we present a formalization of emotion eliciting-events based on a model of the agent's mental state composed of beliefs, choices, and uncertainties. This model enables to identify the emotional state of an agent at any time. We also introduce a computational model based on fuzzy logic that computes facial expressions of emotions blending. Finally, examples of facial expressions resulting from the implementation of our model are shown.

Abstract
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 expressed emotions (the displayed ones), which may differ in real life, In this paper, we present a formalization of emotion eliciting-events based on a model of the agent's mental state composed of beliefs, choices, and uncertainties. This model enables to identify the emotional state of an agent at any time. We also introduce a computational model based on fuzzy logic that computes facial expressions of emotions blending. Finally, examples of facial expressions resulting from the implementation of our model are shown.| File | Dimensione | Formato | |
