Semantic virtual environments

The main problem targeted by this research is the lack of flexibility of virtual objects within a Virtual Environment. Virtual objects are difficult to re-use in applications or contexts different from the ones they were designed for. This refers mainly to ...

EPFL2005

This paper reports on four experimental studies concerning regard to how people use space so as to solve problems collaboratively in virtual environments. Prior to presenting the results, it summarizes the wide range of literature concerning social uses of ...

2005

In this paper we present an object representation based on the semantics and functionality of interactive digital items - virtual objects - within a virtual environment (VE). We consider every object participating in a VE application not only as a 3D shape ...

2005

We are developing a Virtual Reality based training system for micromanipulation in collaboration with the National University Hospital in Singapore. While conventional approaches judge a virtual environment by its resemblance to the real environment, we us ...

2004

In this study, we present an experimental validation of the transmission line representation of an elevated object struck by lightning. The experimental results are obtained using a reduced-scale model and injected signals with narrow pulse widths (down to ...

2003

Describes the haptic rendering of a virtual environment by drawing upon concepts developed in the area of teleoperation. A four-channel teleoperation architecture is shown to be an effective means of coordinating the control of a 3-DOF haptic interface wit ...

Towards autonomous, perceptive, and intelligent virtual actors

Daniel Thalmann

Explains methods to provide autonomous virtual humans with the skills necessary to perform stand-alone roles in films, games and interactive television. We present current research developments in the virtual life of autonomous synthetic actors. After a br ...

Anyone for tennis?

Daniel Thalmann, Amaury Aubel

The authors present a virtual tennis game. They describe the creation and modeling of the virtual humans and body deformations, also showing the real-time animation and rendering aspects of the avatars. They focus on the animation of the virtual tennis bal ...

A rule-based interactive behavioral animation system for humanoids

Daniel Thalmann

We present a versatile, behavioral, and rule-based animation system that includes autonomous humanoid actors whose behavior is based on synthetic sensors that are used for perceiving the virtual environment. We combine the following in a consistent approac ...

Hybrid approaches to interactions between real and virtual humans in mixed environments

Daniel Thalmann

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 ...
