Virtual Reality for Improved Innovative Immersive Interaction

The VR4i Project Team inherits, from the Bunraku Project Team and, before, from the Siames Project Team.

Its purpose is the interaction of users with and through virtual worlds.

Virtual Reality can be defined as a set of models, methods and algorithms that allow one or several users to interact in a natural way with numerical data sensed by means of sensory channels.

"Virtual Reality is a scientific and technological domain exploiting computer science and sensory-motor devices in order to simulate in a virtual world the behavior of 3D entities in real time interaction with themselves and with one or more users in pseudo-natural immersion using multiple sensory channels"

Our main research activity is concerned with real-time simulation of complex dynamic systems, and we investigate real-time interaction between users and these systems.

Our research topics address mechanical simulation, control of dynamic systems, real-time simulation, haptic interaction, multimodal interaction, collaborative interaction and modeling of virtual environments.

Research themes:

Our main concern is to allow real users to interact naturally within shared virtual environments as interaction can be the result of an individual interaction of one user with one object or a common interaction of several users on the same object.

The long-term purpose of the project is to propose interaction modalities within virtual environments that bring acting in Virtual Reality as natural as acting in reality.

Complex physically based models have to be proposed to represent the virtual environment, complex multimodal interaction models have to be proposed to represent natural activity and complex collaborative environments have to be proposed to ensure effective collaborative interactions.

Since users interact both through body and brain, the interaction process needs to be both driven by action and by thought. This yields the need for multimodal acting and rendering. This multimodal interaction with objects within the world implies to develop generic models of the objects of the world and to develop the corresponding multimodal rendering (visual, haptic, audio) and acting (language, gesture or mind).

Long term objectives:

• Improving the accuracy of the virtual environment representation for more interactivity and better perception of the environment;
• Improving the multi-modal interaction for more natural interactions and better perception of the activity;
• Improving the use of virtual environments for real activity and open to human science and engineering science.

Three complementary research axis:

• Physical modeling and simulation of the environment
• Multimodal immersive interaction
• Collaborative work in Collaborative Virtual Environments (CVE)
