Collaborative virtual environments (CVEs) have been studied extensively during the past few years. In this paper, the concept of virtual reality (VR), and its value for group work are critically examined. To ground the discussions, experiences from a virtual reality project, from 3D chats, and from present CVE applications are analysed in the light of human(More)
