Abstract: We survey our research on smart meeting rooms and its relevance for augmented reality meeting support and virtual reality generation of meetings in real-time or off-line. Our aim is to research representations of what takes place during meetings in order to allow generation, e.g. in virtual reality, of meeting activities. This allows us to look at tools that provide support during a meeting and that allow those not able to be physically present during a meeting to take part in a virtual way. This may lead to situations where differences between real, human-controlled, and (semi-) autonomous virtual participants disappear.
