Virtual humans for virtual reality and augmented reality

Daniel Thalmann

The tutorial will explain the techniques for integrating virtual humans into virtual and real environments. It will first present the concept of avatars and autonomous virtual actors and the main techniques to create and animate them (body and face). It wi ...

Real-time augmented face

Daniel Thalmann, Pascal Fua, Vincent Lepetit

This real-time augmented reality demonstration relies on our tracking algorithm described in V. Lepetit et al (2003). This algorithm considers natural feature points, and then does not require engineering of the environment. It merges the information from ...

Stable Real-Time Interaction Between Virtual Humans and Real Scenes

Daniel Thalmann, Pascal Fua, Vincent Lepetit, Michal Ponder

We present an augmented reality system that relies on purely passive techniques to solve the real-time registration problem. It can run on a portable PC and does not require engineering of the environment, for example by adding markers. To achieve this res ...

The enigma of the sphinx

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

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 ...

Strengthening MDA by Drawing from the Living Systems Theory

Alain Wegmann, Otto Preiss

OMGs Model Driven Architecture initiative comes at a time where information system builders and integrators have realized that application design and thus application interoperability is not primarily a technology issue but is about understanding different ...

MPEG-7 CAMERA

Touradj Ebrahimi, Yousri Abdeljaoued, Oscar Divorra Escoda

MPEG-7 camera extends the capabilities of conventional cameras by analyzing its scene in order to generate a contentbased description according to the recently approved MPEG- 7 standard. This gives to the camera a large variety of current and potential app ...

Augmented reality for real and virtual humans

Daniel Thalmann, Pascal Fua, Michal Ponder

Current virtual reality technologies provide many ways to interact with virtual humans. Most of those techniques, however, are limited to synthetic elements and require cumbersome sensors. We have combined a real-time simulation and rendering platform with ...

Handling Occlusion in Augmented Reality Systems: A Semi-Automatic Method

Vincent Lepetit

We present a semi-automatic approach to solve occlu- sion in AR systems. Once the occluding objects have been segmented by hand in selected views called key-frames, the occluding boundary is computed automatically in the in- termediate views. To do that, t ...

Interaction between real and virtual humans in augmented reality

Daniel Thalmann

Interaction between real and virtual humans covers a wide range of topics from creation and animation of virtual actors to computer vision techniques for data acquisition from real world. We discuss the design and implementation of an augmented reality sys ...
