Ce travail a pour but de concevoir, implémenter et évaluer le prototype d'une interface utilisateur multimodale permettant à un chirurgien de communiquer avec divers éléments d'une salle d'opération. ...
Ubiquitous computing is still a maturing field of investigation. The vision of the seamless integration of computers to people’s life has yet to happen, if it ever has to become a reality. Nowadays, most mobile, distributed systems and sensor technologies ...
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 ...
We present a fully automated approach to camera registration for augmented reality systems. It relies on purely passive vision techniques to solve the initialization and real-time tracking problems, given a rough CAD model of parts of the real scene. It do ...
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 ...
Presents the VPARK (Virtual Park) system, which includes a networked virtual environment (NVE) system called W-VLNET and an “attraction building system” that is able to create and modify the attractions used in the NVE. Both systems have been developed in ...
Instead of the reality in which you can see your own limbs, in virtual reality simulations it is sometimes disturbing not to be able to see your own body. It seems to create an issue in the proprioperception of the user who does not completely feel integra ...
This chapter introduces the field of Mixed Reality that merges the real and virtual worlds seamlessly. To develop a Mixed Reality system, two fundamental problems should be addressed: tracking and user interface. Tracking in Mixed Reality is defined as the ...
This thesis presents researches and experiments performed in collaboration with a psychiatrist in order to validate and improve the use of virtual reality in social phobia psychotherapy. Cognitive and behavioral therapies are strongly based on the exposure ...
We analyse use of real-time video in virtual environments in interaction between real and virtual humans. We implemented our ideas in a networked collaborative virtual environment system, VLNET and in an augmented reality setup. This paper presents three d ...
