Asymmetric facial expressions: revealing richer emotions for embodied conversational agents
Daniel Thalmann, Ronan Boulic, Stéphane Gobron, Junghyun Ahn
In this paper, we propose a method to achieve effective facial emotional expressivity for embodied conversational agents by considering two types of asymmetry when exploiting the Valence-Arousal-Dominance representation of emotions. Indeed, the asymmetry o ...
Wiley-Blackwell2013Latent motion spaces for full-body motion editing
We explore an approach to full-body motion edit- ing with linear motion models, prioritized constraint-based optimization and latent-space interpolation. By exploiting the mathematical connections between linear motion mod- els and prioritized inverse kine ...
2013Within-Crowd Immersive Evaluation of Collision Avoidance Behaviors
Daniel Thalmann, Ronan Boulic, Junghyun Ahn, Nan Wang
In this paper, we first present our crowd simulation method, Trajectory Variant Shift (TVS) based on real pedestrian trajectories re-use. We detail how to re-use and shift these trajectories to avoid collisions while retaining the liveliness of captured da ...
ACM2012An Event-Based Architecture to Manage Virtual Human Non-Verbal Communication in 3D Chatting Environment
Daniel Thalmann, Ronan Boulic, Stéphane Gobron, Junghyun Ahn, 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 ...
Springer Berlin Heidelberg2012Sensitivity of hip tissues contact evaluation to the methods used for estimating the hip joint center of rotation
Daniel Thalmann, Ronan Boulic, Jérôme Schmid, Ehsan Arbabi
Computer-based simulations of human hip joints generally include investigating contacts happening among soft or hard tissues during hip movement. In many cases, hip movement is approximated as rotation about an estimated hip center. In this paper, we inves ...
Springer-Verlag2012Conveying Real-Time Ambivalent Feelings through Asymmetric Facial Expressions
Daniel Thalmann, Ronan Boulic, Stéphane Gobron, Junghyun Ahn
Achieving effective facial emotional expressivity within a real-time rendering constraint requests to leverage on all possible inspiration sources and especially from the observations of real individuals. One of them is the frequent asymmetry of facial exp ...
Springer Berlin Heidelberg2012An NVC Emotional Model for Conversational Virtual Humans in a 3D Chatting Environment
Daniel Thalmann, Ronan Boulic, Stéphane Gobron, Junghyun Ahn, 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 ...
Springer Berlin Heidelberg2012An Interdisciplinary VR-Architecture for 3D Chatting with Non-verbal Communication
Daniel Thalmann, Stéphane Gobron, Junghyun Ahn, 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 ...
Eurographics Association2011Bridging Digital and Physical Worlds Using Tangible Drag-and-Drop Interfaces
Daniel Thalmann, Frédéric Vexo, Mathieu Hopmann
The last ten years have seen an explosion in the diversity of digital-life devices, e.g. music and video players. However, the interaction paradigm to use these devices has remained mostly unchanged. Remote controls are still the most common way to manage ...
Springer Verlag2011Natural Activation for Gesture Recognition Systems
Daniel Thalmann, Patrick Salamin, Frédéric Vexo, Mathieu Hopmann
Gesture recognition is becoming a popular way of interaction, but still suffers of important drawbacks to be integrated in everyday life devices. One of these drawbacks is the activation of the recognition system – trigger gesture - which is generally tiri ...
