Sensitivity 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 ...

Conveying Real-Time Ambivalent Feelings through Asymmetric Facial Expressions

Daniel Thalmann, Ronan Boulic, Junghyun Ahn, Stéphane Gobron

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 ...

Long Term Real Trajectory Reuse Through Region Goal Satisfaction

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

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 ...

CYBEREMOTIONS – Collective Emotions in Cyberspace

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn

Emotions are an important part of most societal dynamics. As with face to face meetings, Internet exchanges may not only include factual information but may also elicit emotional responses; how participants feel about the subject discussed or other group m ...

Evaluation of a geometry-based knee joint compared to a planar knee joint

Daniel Thalmann, Anders Sandholm

Today neuromuscular simulations are used in several fields, such as diagnostics and planing of surgery, to get a deeper understanding of the musculoskeletal system. During the last year, new models and datasets have been presented which can provide us with ...

A visualization framework for the analysis of neuromuscular simulations

Daniel Thalmann, Anders Sandholm

We present a visualization framework for exploring and analyzing data sets from biomechanical and neuromuscular simulations. These data sets describe versatile information related to the different stages of a motion analysis. In studying these data using a ...

Quantifying effects of exposure to the third and first-person perspectives in virtual-reality-based training

Daniel Thalmann, Olaf Blanke, Ravi Tej Sai Giridhar Tadi, Patrick Salamin, Frédéric Vexo

In the recent years, usage of the third-person perspective (3PP) in virtual training methods has become increasingly viable and despite the growing interest in virtual reality and graphics underlying third-person perspective usage, not many studies have sy ...

Sentiment analysis of informal textual communication in cyberspace

Daniel Thalmann, Stéphane Gobron

The ability to correctly identify the existence and polarity of emotion in informal, textual communication is a very important part of a realistic and immersive 3D environment where people communicate with one another through avatars or with an automated s ...

Providing the best Third-Person Perspective to a Video-Through HMD

Daniel Thalmann, Patrick Salamin, Frédéric Vexo

This paper describes a system with several fixed cameras that provide Third-Person Perspective (3PP) to the video-through HMD of the user. Once done, our system uses an algorithm to make intelligent switches between the different cameras in order to provid ...
