In this chapter we consider the role virtual conferencing has to play in realising a successful Inhabited Information Space (IIS). For any IIS to be successful it needs to weave together many different constituent elements and present these in a coherent and seamless manner. For example, Maher et al (2000) describe how many different components are used together to create a virtual design studio for architectural collaboration. For the IIS to function all the elements must work both individually and collectively. Communication is one of the basic building blocks for an IIS, and can be in many modes across many media. Approaches to virtual conferencing offer support for communication across a number of media and can be utilised in an IIS. These approaches are also starting to additionally offer support for collaboration. By providing an introduction to and overview of various possibilities for virtual conferencing we aim to show how these solutions can provide the required and appropriate support for communication and collaboration between inhabitants in a shared information space. Of course virtual conferencing solutions exist at many levels of sophistication and fidelity. Communication media can range from text through 3d graphics to video representations. The aim of this chapter is to present these many and varied possibilities, drawing on the experience of the author as well as insights into the past, present and future. In this way it is possible to see how diverse a range of IISes can make use of virtual conferencing functionality.
