In this paper we propose a computational model for the real time generation of nonverbal behaviors supporting the expression of interpersonal attitudes for turn-taking strategies and group formation in multi-party conversations among embodied conversational agents. Starting from the desired attitudes that an agent aims to express towards every other(More)

Laughter is a social signal capable of facilitating interaction in groups of people: it communicates interest, helps to improve creativity, and facilitates sociability. This article focuses on: endowing virtual characters with computational models of laughter synthesis, based on an expressivity-copying paradigm; evaluating how the physically co-presence of(More)
In this paper we present an analysis from a corpus of dyadic expert-novice knowledge sharing interactions. The analysis aims at investigating the relationship between observed non-verbal cues and first impressions formation of warmth and competence. We first obtained both discrete and continuous annotations of our data. Discrete descriptors include(More)
In the context of IMPRESSIONS project, we analyzed a corpus of human-human interactions with both discrete and continuous annotations, in order to investigate nonverbal cues associated to warmth and competence impressions. Preliminary results show an association between perceived competence variations (increase or decrease) and smile, type of gestures and(More)
Laughter is an important social signal which may have various communicative functions (Chapman 1983). Humans laugh at humorous stimuli or to mark their pleasure when receiving praised statements (Provine 2001); they also laugh to mask embarrassment (Huber and Ruch 2007) or to be cynical. Laughter can also act as social indicator of in-group belonging(More)
In this abstract we introduce the design of an experiment aimed at investigating how users' impressions of an embodied conversational agent are influenced by agent's non-verbal behaviour. We focus on impressions of warmth and competence, the two fundamental dimensions of social perception. Agent's gestures, arms rest poses and smile frequency(More)
