Our aim is to create an affective Embodied Conversational Agent (ECA); that is an ECA able to display communicative and emotional signals. Nonverbal communication is done through certain facial expressions, gesture shapes, gaze direction, etc. But it can also carry a qualitative aspect through behavior expressivity: how a facial expression, a gesture is executed.

An interactive artificial agent is supposed to be a feasible tool to reveal how humans recognize and respond to another’s response and should be developed through the investigation of the human cognitive mechanism. Previous studies have suggested that humans are sensitive to the responses of the interactant and might relate them to the interactant’s communicativeness. Following on from the find...

Many studies have shown that people imitate and repeat each other’s behaviors. This holds for both verbal and nonverbal behavior. The production of co-speech hand gestures is a special case of nonverbal behavior, because it is believed to be tightly linked to verbal language production and because gestures can carry meaning in a way that is similar to verbal language.

For example, appellatecourts have cautioned repeatedly that juries in criminal trials accord even themost subtle behaviors of the judge great weight and deference.

Embodied conversational agents (ECA) should exhibit nonverbal behaviors that are meaningfully related to their speech and mental state. This paper describes Cerebella, a system that automatically derives communicative functions from the text and audio of an utterance by combining lexical, acoustic, syntactic, semantic and rhetorical analyses. Communicative functions are then mapped to a multimo...

Previous studies have found that various nonverbal behaviors performed by women are associated with men approaching. A female confederate was instructed either to smile or to not smile at a man when entering a bar. It was found that those men who were smiled at approached the woman and considered her more favorably. This effect is explained in accordance with studies that found smiling enhanced...

We describe studies underway of nonverbal and verbal aspects of adult human dyadic interactions in three language/cultural groups: Iraqi Arabic-, Mexican Spanish-, and American English-speaking cultures. Previous studies have identified cross-cultural differences in the diverse multi-modal behaviors, such as headnod, gaze and posture, that support interactional rapport by signaling engagement o...

The authors address the decades-old mystery of the association between individual differences in the expression and perception of nonverbal cues of affect. Prior theories predicted positive, negative, and zero correlations in performance-given empirical results ranging from r = -.80 to r = +.64. A meta-analysis of 40 effects showed a positive correlation for nonverbal behaviors elicited as inte...
