Haptic instrumentation for an interventional radiology simulator

Dejan Ilic

Low trauma, reduced costs and fast recovery are only a few factors why minimally invasive surgery (MIS) is taking over classical surgical methods. Interventional Radiology (IR) is a minimally invasive procedure where thin tubular instruments are steered th ...

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 ...

Content Understanding for Smart Multimedia Systems

Michael Ansorge

The paper is presenting a core idea of the research line, dedicated to tools and utilities for a more friendly information access. In order to make future multimedia systems smarter, new mechanisms for high-level data and user understanding need to be embe ...

Dynamic thread for real-time knot-tying

Etienne Burdet, Fei Wang, Ankur Dhanik

Real-time simulation of knot-tying with visual and force feedback is essential to VR surgery training. We present a physics-based simulator that enables realistic knot tying at haptic speed. The virtual thread obeys Newton's laws and behaves naturally. The ...

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 ...

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 ...

Multi-Scale Simulation For Microsurgery Trainer

Etienne Burdet, Fei Wang, Zheng Li

For use in a Virtual Reality based training system for surgical micromanipulation, we have developed a fast multi- scale FEM algorithm that concentrates detail where needed while still handling global deformations. The resulting 6- to 7-fold speed up is pr ...

An informed environment for inhabited city simulation

In combination with the rapid technical improvements of computers, building large virtual scenes has become a popular field in computer graphics for education, films or games. Often, virtual humans populate scenes such as real reconstructed city, disappear ...

Distributed Architecture for Teleoperation over the Internet.

Denis Gillet, Christophe Salzmann

This paper discusses challenges in enabling teleoperation over the Inter net for the specific case of real systems which exhibit fast dynamics.A distributed client-server architecture is proposed to provide the necessary level of interactiv ity for supervi ...

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 ...
