An NVC Emotional Model for Conversational Virtual Humans in a 3D Chatting Environment

Ronan Boulic, Daniel Thalmann, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre

This paper proposes a new emotional model for Virtual Humans (VHs) in a conversational environment. As a part of a multi-users emotional 3D-chatting system, this paper focus on how to formulate and visualize the flow of emotional state defined by the Valen ...

An Event-Based Architecture to Manage Virtual Human Non-Verbal Communication in 3D Chatting Environment

Ronan Boulic, Daniel Thalmann, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre

Non-verbal communication (NVC) makes up about two-thirds of all communication between two people or between one speaker and a group of listeners. However, this fundamental aspect of communicating is mostly omitted in 3D social forums or virtual world orien ...

Long Term Real Trajectory Reuse Through Region Goal Satisfaction

Ronan Boulic, Daniel Thalmann, Pascal Fua, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre, Horesh Beny Ben Shitrit, Mirko Raca

This paper is motivated by the objective of improving the realism of real-time simulated crowds by reducing short term collision avoidance through long term anticipation of pedestrian trajectories. For this aim, we choose to reuse outdoor pedestrian trajec ...

An Interdisciplinary VR-Architecture for 3D Chatting with Non-verbal Communication

Daniel Thalmann, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre

The communication between avatar and agent has already been treated from different but specialized perspectives. In contrast, this paper gives a balanced view of every key architectural aspect: from text analysis to computer graphics, the chatting system a ...

Asymmetrical Facial Expressions based on an Advanced Interpretation of Two-dimensional Russells Emotional Model

Daniel Thalmann, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre

This paper proposes a novel method to compute emotional parameters based on Russell's 2D circumplex diagram for simulating and visualizing asymmetric facial expressions. Based on a large set of emotion coordinates allocated by psychologists, we have select ...
