Copresence and interaction in virtual environments: An overview of the range of issues

Studies of shared virtual environments (SVEs) have used widely different approaches to how copresence and interaction should be analyzed. In this paper, I argue that- if we take our starting point from what people actually do in shared VE's, and findings about what they do together- then we can focus much more narrowly on the few essential features of interaction in SVEs. To do this, I review the different disciplinary approaches to SVEs and the range of findings in this field, and conclude by suggesting how the field can advance
