Two-handed haptic feedback in generic virtual environments

Renaud Ott

Since [years] we hear about Virtual Reality as a discipline that could potentially provide benefits to many applications. Basically, the principle of Virtual Reality consists in stimulating user senses in order to give the impression to be in another place ...

Characterizing full-body reach duration across task and viewpoint modalities

Daniel Thalmann, Ronan Boulic, Damien Maupu

The full-body control of virtual characters is a promising technique for application fields such as Virtual Prototyping. However it is important to assess to what extent the user full-body behavior is modified when immersed in a virtual environment. In the ...

Crowds of Moving Objects: Navigation Planning and Simulation

Daniel Thalmann, Helena Stephanie Grillon Le Gallennec

This paper presents a solution to interactive navigation planning and real-time simulation of a very large number of entities moving in a virtual environment. From the environment geometry analysis, we deduce a structure called navigation graph, which is t ...

Visualization Learning for Visually Impaired People

Daniel Thalmann, Patrick Salamin, Frédéric Vexo

Virtual Environments (VE) are mainly visual experiments that exclude visually impaired people. In this paper we present an application that should allow almost everybody to ``see'' or at least to perceive 3D shapes. We will first describe the mandatory asp ...

Accurate On-line Avatar Control with Collision Anticipation

Daniel Thalmann, Ronan Boulic, Manuel Peinado, Daniel Raunhardt, Damien Maupu

Interactive control of a virtual character through full body movement has a wide range of applications. However, there is a need for systems that accurately reproduce the motion of a performer while accounting for surrounding obstacles. We propose an appro ...

Multimodal authoring tool for populating a database of emotional reactive animations

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

We aim to create a model of emotional reactive virtual humans. This model will help to define realistic behavior for virtual characters based on emotions and events in the virtual environment to which they react. A large set of pre-recorded animations will ...

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 ...

Real-time navigating crowds: Scalable simulation and rendering

Daniel Thalmann, Jonathan Maim, Barbara Yersin

This paper introduces a framework for real-time simulation and rendering of crowds navigating in a virtual environment. The solution first consists in a specific environment preprocessing technique giving rise to navigation graphs, which are then used by t ...

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 ...

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 ...
