Multi-finger haptic rendering of deformable objects

Daniel Thalmann, Ronan Boulic, Sofiane Sarni, Anderson Maciel, Olivier Buchwalder

The present paper describes the integration of a multi-finger haptic device with deformable objects in an interactive environment. Repulsive forces are synthesized and rendered independently for each finger of a user wearing a Cybergrasp force-feedback glo ...

Simulation of nonverbal social interaction and small groups dynamics in virtual environments

Anthony Guye-Vuillème

How can the behaviour of humans who interact with other humans be simulated in virtual environments? This thesis investigates the issue by proposing a number of dedicated models, computer languages, software architectures, and specifications of computation ...

This paper presents a novel method of collaborative problem solving for intelligent agents in virtual environments. We describe a planner for STRIPS-like domains enhanced by techniques of "delegated computing". Instead of having one central planner with co ...

Multisensory learning cues using analytical collision detection between a needle and a tube

Etienne Burdet, Fei Wang

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 ...

Behavioral animation of autonomous virtual agents helped by reinforcement learning

Daniel Thalmann, Toni Conde

Our research focuses on the behavioral animation of virtual humans who are capable of taking actions by themselves. We deal more specifically with reinforcement learning methodologies, which integrate in an original way the RL agent and the autonomous virt ...

Environmental Modeling with Fingerprint Sequences for Topological Global Localization

Roland Siegwart, Nicola Tomatis, Adriana Tapus, Pierre Lamon

In this paper a perception approach allowing for high distinctiveness is presented. The method works in accordance to the fingerprint concept. Such representation allows using a very flexible matching approach based on the minimum energy algorithm. The who ...

2003

An integrated framework is proposed in which local perception and close manipulation skills are used in conjunction with a high-level behavioral interface based on a "smart object" paradigm as support for virtual agents to perform autonomous tasks. In our ...

Towards interactive real-time crowd behavior simulation

Daniel Thalmann, Branislav Ulicny

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 ...

Sharing attractions on the Net with VPark

Daniel Thalmann, Joaquim Esmerado

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 ...

ACE: a platform for the real time simulation of virtual human agents

Daniel Thalmann, Jean-Sébastien Monzani

The paper describes a system platform for virtual human agent simulations that is able to coherently manage the shared virtual environment. Our “agent common environment” (ACE) provides built-in commands for perception and for acting, while the ...
