3D Interaction

i3D is a recent research group dedicated to one of the main challenges of virtual reality, interaction. Many models and algorithms used in virtual reality can be borrowed from more traditional workstation applications (visualization, simulation,..). However, one of the main pluses, hence primary challenges, of virtual reality is multisensorial, immersive interaction.

i3D concentrates on 3D interaction primarily for virtual environments. Research is being carried out in particular on large screen immersive visualization devices with haptic feedback.
"Our long term objective is to contribute to making interaction with virtual worlds as simple, intuitive and comfortable as with the real world," says Sabine Coquillart. In this research, i3D comes in on several complementary levels:
(1) study and design of interaction paradigms or metaphors,
(2) haptic interaction,
(3) interaction techniques or peripheral evaluation and human factors.

Since its creation, i3D has selected a virtual reality configuration that is the basis of most of its work. The configuration is a virtual workbench. This choice was motivated by the very strong potential of this configuration in terms of interaction, due to the direct handling of the virtual model, among other factors.

One of the goals of the i3D group is to enrich this configuration, and more generally all virtual reality configurations, with additional interaction and sensory feedback paradigms, such as force feedback.

The i3D teams have already developed specific tools such as:

* The MiniFly virtual reality software platform
* The Contact ToolKit collision and constraint management libraries
* The Command and Control Cube application control system
* The 3D Metric Cursor
* Force feedback on the virtual workbench using the SPIDAR system.

i3D is also working on more fundamental aspects such as psychophysical evaluation and non active haptic feedback modes such as pseudo-haptic feedback.

The applications envisioned are the visualization, handling and interactive simulation of complex data in such varied application fields as engineering, geoscience, chemistry and biology, among others.

i3D has always maintained productive collaborations with many industrial or academic partners in France and abroad, such as:

* EADS and Dassault on the virtual prototyping theme,
* Renault on the theme of force feeback in virtual reality,
* TGS, the BRGM, IFP, the CEA and the University of Orléans on scientific visualization in virtual reality,
* CEA on force feedback,
* The LRP (Paris Robotics Laboratory) and the University of Evry on virtual prototyping and haptic feedback,
* The IAS on the visualization of the solar system,
* The Technion Institute in Tel Aviv on remote modeling over the Web,
* The GMD in Germany for various works on the virtual workbench,
* The TIT (Tokyo Institute of Technology, Japan) on the integration of the SPIDAR force feedback system into the virtual workbench.
