Research Topics

My research work is focused on Distributed Virtual Reality (DVR) and
more specifically MMVEs (Massively Multiuser Virtual Environments) and MMOGs (Massively Multiuser Online Games).

The full list of my publications can be found here.

Current Research Activities

My work is divided along 3 axes:

1.Networked VEs Interoperability
I'm mainly interested in HLA (High Level Architecture), CORBA and CCM (Corba Component Model) as ways to enable interoperability between Networked Virtual Worlds and Systems.
The most recent paper detailing this research can be found here: Wafaa Abou Moussa, Nelly de Bonnefoy, Emmanuel Dubois, Patrice Torguet, Jean-Pierre Jessel.
Virtual reality simulation for prototyping augmented reality. In : International Symposium on Ubiquitous Virtual Reality (ISUVR 2008), Gwangju, Korea, 10/07/2008-13/07/2008, IEEE Computer Society, pp. 55-58, July 2008.

2.Networked VEs Optimizations
I'm working on techniques like dead-reckoning and area of interest management.
This researched is detailed in the following papers:
Souad Elmerhebi, Jean-Christophe Hoelt, Patrice Torguet, Jean-Pierre Jessel.
Perception Based Filtering for MMOGs. In : International Journal of Computer Games Technology, Hindawi Publishing Corporation, Special issue Joint International Conference on Cyber Games and Interactive Entertainment 2006, Vol. 2008 N. Article ID: 243107, (on line), April 2008.
Samir Torki, Patrice Torguet, Cédric Sanza.
Adaptive Classifier System-Based Dead Reckoning. In : Eurographics Symposium on Virtual Environments (EGVE 2007), Weimar, Allemagne, 15/07/2007-18/07/2007, Vol. virtual environments 2007, Eurographics, pp. 101-108, July 2007.
Note: if you are not an EG member you won't be able to access the full paper but
here is my copy.

3.Serious Games as applications of Networked VEs
I'm working on Serious Games applied to computer programming. The project is called Prog&Play and is detailed in the following paper: Mathieu Muratet, Patrice Torguet, Jean-Pierre Jessel, Fabienne Viallet.
Towards a Serious Game to Help Students Learn Computer Programming. In : International Journal of Computer Games Technology, Hindawi Publishing Corporation, Vol. 2009, (on line), 2009.

Research Experience

•1993 - 1998 : PhD thesis
IRIT, University Paul Sabatier (UPS), Toulouse. « VIPER : Un modèle de calcul réparti pour la gestion d'environnements virtuels »: the thesis deals with distributed virtual reality. I designed and coded a networked VE system called VIPER (VIrtuality Programming EnviRonment)

•1998 - 1999 : Post-doctorate, UPS, Toulouse.
I worked on the EU ESPRIT project Cavalcade (CollAborative VirtuAL Construction And DEsign).
I developed a specific version of VIPER for this project.

•1999 - 2000 : Engineer, Virtual Reality Division, CS SI, Toulouse.
I worked on ACE2 (VR tool helping remote control of submarine vessels) for Ifremer (French Research Institute for Exploitation of the Sea)
and on EU ESPRIT project Visions (A virtual studio for digital storytelling).

•2000 - Today : Maître de Conférences (Assistant Professor), UPS, Toulouse.

  1. Currently:

  2.    I'm working with University of Guadalajara, Mexico on the DVRMedia 2 project.

  3.   I'm working with OMP (Observatoire Midi Pyrénées) and the ELIPSE team in IRIT on the TBL 3D project.

I worked with CS-SI Virtual Reality Division on the following projects: PROVIS, CAVALCADE, ACE2, VISIONS and WAVES.
I worked with Oktal on the IMAGE project. I also worked on the Mecagenius Project with KTM Advance, CUFR Champollion and UMR EMFTS.
