Eye Contact as Trigger for Modification of Virtual Character Behavior

Daniel Thalmann, Helena Stephanie Grillon Le Gallennec

The increasing use of Virtual Reality in the treatment of phobias translates in a just as expanding need for realism in its scenes and characters. Virtual characters need to seem gifted with intelligence. A first step in achieving this is by giving them th ...

Practical Design and Implementation of a CAVE Environment

Daniel Thalmann, Frédéric Vexo, Sylvain Cardin, Achille Peternier

CAVE systems are nowadays one of the best Virtual Reality (VR) immersive devices available for rendering virtual environments. Unfortunately, such kind of hardware is extremely expensive, complex and cum-bersome, thus limited in its spread. Several cheaper ...

An integrated perception for autonomous virtual agents: active and predictive perception

Daniel Thalmann, Toni Conde

This paper presents an original model with methodologies that integrate in a novel way different types of an autonomous virtual agent's perception in a virtual environment. Our first new approach permits the coherent management of the shared virtual enviro ...

Object manipulation and grasping for virtual humans

Tolga Abaci

Virtual environments need virtual humans that are capable of interacting with objects around them. Existing virtual environments have not found satisfactory general solutions for this problem. The common method is to combine pre-designed (or motion capture ...

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 ...

Virtual humans: thirty years of research, what next?

Daniel Thalmann

In this paper, we present research results and future challenges in creating realistic and believable virtual humans. To realize these modeling goals, real-time realistic representation is essential, but we also need interactive and perceptive virtual huma ...

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 ...
