Virtual humans for virtual reality and augmented reality
Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Real-time 3D graphics are being extensively used to build interactive virtual environments for a number of different applications. In many situations, virtual objects are required to exhibit complex behaviors, and the use of a versatile behavioral programm ...
We present a networked virtual environment (NVE) system and an attraction building system based on Windows NT that enables users to introduce their own scenario-based applications into a shared virtual environment. Our goal was to develop and integrate sev ...
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 ...
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 ...
This paper discusses the main issues for creating interactive virtual environments with virtual humans emphasizing the following aspects: creation of virtual humans, gestures, interaction with objects, multimodal communication ...
In the past decade, networked virtual environments (NVEs) have been an increasingly active area of research, with the first commercial systems emerging recently. Graphical and behavioral representation of users within such systems is a particularly importa ...
The paper describes a versatile, robust, and parametric ball animation model that can be used in many types of interactive virtual reality (VR) environments. The generic model is particularly useful for animation of ball-like objects such as tennis balls a ...
While virtual crowds are becoming common in non-real-time applications, the real-time domain is still relatively unexplored. In this paper we discuss the challenges involved in creating such simulations, especially the need to efficiently manage variety. W ...
We describe an approach to construct interactive virtual environments, which are suitable for the development of artificial virtual human life simulations. Our main goal is to have virtual human actors living and working autonomously in virtual environment ...
