Collaborative Virtual Environments (CVEs) are complex environments where multiple users share the same objects to act together. The complexity of these environments is related to the interaction of the user group with shared items. In a shared world, several constraints appear, including those related to coordination and communication of users and user interaction management in virtual world towards objects and other users. This paper presents a useful workflow-based approach to manage 3D interactions and enhance presence in CVEs. This approach combines astutely different concepts from two research domains: CSCW and VR.
