Real-time textured volume reconstruction using virtual and real video cameras

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn

Reconstructing objects in three dimensions (3D) has always been one of the primary tasks in the domain of computer graphics (CG). Succeeding in this task in real-time, including texture reconstruction, and with very low-cost hardware is the challenge prese ...

Improving user comfort in haptic virtual environments through gravity compensation

Daniel Thalmann, Frédéric Vexo

Our experience with a Haptic Workstation™ has shown that this device is uncomfortable to use during long sessions. The main reason is the uncomfortable posture of the arms, which must be kept outstretched horizontally while supporting the weight of an exos ...

Use of Virtual Reality as Therapeutic Tool for Behavioural Exposure in the Ambit of Social

Daniel Thalmann, Bruno Herbelin

We hereby present a study whose aim is to evaluate the efficiency and flexibility of virtual reality as a therapeutic tool in the confines of a social phobia behavioural therapeutic program. Our research protocol, accepted by the ethical commission of the ...

Robust on-line adaptive footplant detection and enforcement for locomotion

Daniel Thalmann, Ronan Boulic, Pascal Glardon

A common problem in virtual character computer animation concerns the preservation of the basic foot-floor constraint (or footplant), consisting in detecting it before enforcing it. This paper describes a system capable of generating motion while continuou ...

Mediators: virtual haptic interfaces for tele-operated robots

Daniel Thalmann, Frédéric Vexo

This paper develops the concept of mediators: virtual interfaces with haptic feedback for teleoperation. Our approach is to replace physical operator interfaces by fully parameterizable adaptive virtual interfaces. Mediators open new possibilities for mult ...

Intelligent switch: An algorithm to provide the best third-person perspective in augmented reality

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Augmented reality (AR) environments are suffering from a limited workspace. In addition, registration issues are also increased by the use of a mobile camera on the user that provides a first-person perspective (1PP). Using several fixed cameras reduces th ...

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

Daniel Thalmann, Ronan Boulic, 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 ...

In Search for your own Virtual Individual

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

The use of inhabited Virtual Environments is continuously growing. People can embody a human-like avatar to participate inside these Virtual Environments or they can have personalized character acting as mediator; sometimes they can even customize it to so ...

Dynamic Obstacle Clearing for Real-time Character Animation

Daniel Thalmann, Ronan Boulic, Pascal Glardon

This paper proposes a novel method to control virtual characters in dynamic environments. A virtual character is animated by a locomotion and jumping engine, enabling production of continuous parameterized motions. At any time during runtime, flat obstacle ...

The mobile animator: interactive character animation in collaborative virtual environments

Daniel Thalmann, Frédéric Vexo

We have designed a mobile -PDA-based- interface for real-time control of virtual characters in multiuser semi-immersive virtual environments - using a large rear-projection screen. The proof-of-concept implementation we present shows the potential of handh ...

Conducting a virtual orchestra

Daniel Thalmann, Frédéric Vexo, Sébastien Schertenleib

The virtual orchestra is a multimodal system architecture based on complex 3D sound environment processing and a compact user interface. The system architecture supports high-performance sound content for VR (virtual reality) applications, and the user con ...

MHAPTIC : a Haptic Manipulation Library for Generic Virtual Environments

Daniel Thalmann, Frédéric Vexo

This paper presents a new library called MHaptic for bimanual haptic interaction within generic virtual environments. It has been specifically designed to work with a Haptic Workstation. MHaptic provides tools for accelerated development of virtual environ ...

Simulating gaze attention behaviors for crowds

Daniel Thalmann

Crowd animation is a topic of high interest which offers many challenges. One of the most important is the trade-off between rich, realistic behaviors, and computational costs. To this end, much effort has been put into creating variety in character repres ...

Design of a Flexible Articulated Robotic Hand for a Humanoid Robot

Daniel Thalmann

It is often desirable for humanoid robots to have dexterous hands and perform human-like grasps. This requires a deliberate design of hands, in addition to a good actuation system and an efficient 3D vision system. In this paper, we present a simple method ...

The enigma of the sphinx

Daniel Thalmann, Frédéric Vexo, Tolga Abaci, Jan Ciger, Olivier Renault, Mireille Clavien

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application "The Enigma of the Sphinx". The interface consists of a large projection sc ...

Immersive flight for surveillance applications

Daniel Thalmann, Frédéric Vexo, Sylvain Cardin, Xavier Righetti

In this paper , we present a VR-based first-person view paradigm applied to a tele-surveillance application. Using an Unmanned Air Vehicle (UAV), we have developed an intuitive tangible interface between the pilot and his airship (blimp). The idea is to ma ...

Multimodal authoring tool for populating a database of emotional reactive animations

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

We aim to create a model of emotional reactive virtual humans. This model will help to define realistic behavior for virtual characters based on emotions and events in the virtual environment to which they react. A large set of pre-recorded animations will ...

On-line adapted transition between locomotion and jump

Daniel Thalmann, Ronan Boulic, Pascal Glardon

Motion blending is widely accepted as a standard technique in computer animation, allowing the generation of new motions by interpolation and/or transition between motion capture sequences. To ensure smooth and seamless results, an important property has t ...

Eye-tracking as Diagnosis and Assessment Tool for Social Phobia

Daniel Thalmann

In this study, we evaluate the usability of an eyetracking system as a diagnosis and assessment tool for visual avoidance behaviors in the context of social anxiety disorders. We conducted this study over five social phobic patients and five non phobic peo ...

An ontology of virtual humans: Incorporating semantics into human shapes

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez, Laurent Moccozet

Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...
