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.

The long term objectives of VR4i are:

• 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 for evaluation and to engineering science for applications.

Thus, we propose three complementary research axes:

• Physical modeling and simulation of the environment

• Multimodal immersive interaction

• Collaborative work in Collaborative Virtual Environments (CVE)
