Collaboration with agents in VR environments

Jan Ciger

Virtual reality is gaining on importance in many fields – scientific simulation, training, therapy and also more and more in entertainment. All these applications require the human user to interact with virtual worlds inhabited by intelligent characters an ...

Autonomous virtual agents learning a cognitive model and evolving

Daniel Thalmann, Toni Conde

In this paper, we propose a new integration approach to simulate an autonomous virtual agent's cognitive learning of a task for interactive virtual environment applications. Our research focuses on the behavioural animation of virtual humans capable of act ...

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 ...

Crowds for interactive virtual environments

Branislav Ulicny

Crowds are part of our everyday experience; nevertheless, in virtual worlds they are still relatively rare. In this thesis we explore the challenges of bringing crowds into interactive virtual environments and the possible applications of real-time interac ...

Conducting a virtual orchestra

Daniel Thalmann, Frédéric Vexo, Sébastien Schertenleib

The virtual orchestra is a multimodal system architecture based on complex 3D sound environment processing and a compact user interface. The system architecture supports high-performance sound content for VR (virtual reality) applications, and the user con ...

Design of a haptic forceps for microsurgery training

Hannes Bleuler, Roger Gassert, Etienne Burdet, Fei Wang

While feedback of the grasping force is necessary to manipulate objects skillfully, most Virtual Reality systems do not provide such feedback. Grasping an object is often reduced to pushing a button on the interface. This paper presents the design and real ...

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 ...

Biosphera: A Prototype Design for Learning about Multivariate Systems

Mauro Cherubini

This paper presents a prototype learning environment for children to create their own knowledge about multivariate systems. We developed a virtual world linked to a tabletop-sized physical dome in which children experiment with envirojnmental parameters af ...

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 ...

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 ...
