An Ontology of Virtual Humans: Incorporating Semantics into Human Shapes

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...

Improving user comfort in haptic virtual environments through gravity compensation

Daniel Thalmann, Frédéric Vexo, Renaud Ott

Our experience with a Haptic Workstation™ has shown that this device is uncomfortable to use during long sessions. The main reason is the uncomfortable posture of the arms, which must be kept outstretched horizontally while supporting the weight of an exos ...

VR haptic interfaces for teleoperation: an evaluation study

Daniel Thalmann, Frédéric Vexo, Renaud Ott

We present the results of an evaluation study in the framework of user interfaces for teleoperation of vehicles. We developed a virtual cockpit with haptic feedback provided by a Haptic Workstation™. Four alternative teleoperation interfaces were implement ...

Acquiring, structuring shapes and annotating them with semantics to improve design activities

Daniel Thalmann, Frédéric Vexo

Shapes incorporate geometry as well as semantics and can be defined in 2D, 3D or higher dimensions. Geometric models can be structured in such a way that they can provide a relevant framework to insert semantic information or view dependent information abo ...

The mobile animator: interactive character animation in collaborative virtual environments

Daniel Thalmann, Frédéric Vexo

We have designed a mobile -PDA-based- interface for real-time control of virtual characters in multiuser semi-immersive virtual environments - using a large rear-projection screen. The proof-of-concept implementation we present shows the potential of handh ...

Conducting a virtual orchestra

Daniel Thalmann, Sébastien Schertenleib, Frédéric Vexo

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 ...

Mediators: virtual haptic interfaces for tele-operated robots

Daniel Thalmann, Frédéric Vexo, Renaud Ott

This paper develops the concept of mediators: virtual interfaces with haptic feedback for teleoperation. Our approach is to replace physical operator interfaces by fully parameterizable adaptive virtual interfaces. Mediators open new possibilities for mult ...

The enigma of the sphinx

Daniel Thalmann, Mireille Clavien, Olivier Renault, Frédéric Vexo, Tolga Abaci, Jan Ciger

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application "The Enigma of the Sphinx". The interface consists of a large projection sc ...
