Mechanisms of Realistic Facial Expressions for Anthropomorphic Social Agents

Analysis and Reproduction of Facial Expressions for Realistic Communicating Clones

This paper presents a novel view-based approach to quantify and reproduce facial expressions, by systematically exploiting the degrees of freedom allowed by a realistic face model. This approach embeds e cient mesh morphing and texture animations to synthesize facial expressions. We suggest using eigenfeatures, built from synthetic images, and designing an estimator to interpret the responses o...

Subtleties of facial expressions in embodied agents

Our goal is to develop a Believable Embodied Agent able to dialog with a user, but we aim at making an Agent that can also combine facial expressions in a complex and subtle way, just like a Human Agent does. We first review a taxonomy of communicative functions that our Agent is able to express non-verbally; but we point out that, due to the complexity of communication, in some cases different...

Social Use of Facial Expressions in Hylobatids

Non-human primates use various communicative means in interactions with others. While primate gestures are commonly considered to be intentionally and flexibly used signals, facial expressions are often referred to as inflexible, automatic expressions of affective internal states. To explore whether and how non-human primates use facial expressions in specific communicative interactions, we stu...

Role of facial expressions in social interactions.

The expressions we see in the faces of others engage a number of different cognitive processes. Emotional expressions elicit rapid responses, which often imitate the emotion in the observed face. These effects can even occur for faces presented in such a way that the observer is not aware of them. We are also very good at explicitly recognizing and describing the emotion being expressed. A rece...
