A New Model of Collaborative 3D Interaction in Shared Virtual Environment

International audienceRecent advances in both Virtual Reality (VR) systems and Computer-Supported Cooperative Work (CSCW) technologies have resulted in the appearance of the Collaborative Virtual Environments (CVEs) systems supporting different forms of collaboration and interaction between users. The collaboration in these systems refers to the simultaneous interaction (collaborative interaction) of multiple users on a virtual object in an immersive or semi-immersive Virtual Environment (VE). However, in some cases, the collaborative interaction is reduced to a simple communication between users. In this paper, we propose a new model of collaborative interaction that supports group interaction in CVEs. Our model defines the functional role and the functional clover of the 3D interaction. This Model is based on group awareness concepts (focus, nimbus and degree of interaction) combined with 3D interaction paradigms (navigation, selection and manipulation). The aim of our model is to manage and control the simultaneous user actions
