On Monday morning I had a very interesting experience as I gave a presentation for a group of students at the Informatics Department (the HCID Group) in Lund via web camera. The topic of my talk was, very appropriately, Close at a distance: Presence in a digital age. The notion of presence has always played a role in my research but from somewhat different perspectives, and it was great fun to try and pull all the strings together in one presentation. I started off by giving some examples of computer applications which in different ways can allow for people to experience a sense of presence (VR, advanced presence indicators like Hexagon, MSN Messenger, blogs etc.) and in so doing I also went over some of the different definitions and causes of presence (perceptual stimuli, immediacy, intimacy, immersion through text etc.). I then referred to how presence relates to my own work and talked about how under some circumstances you want a high degree of presence, whereas under others the opposite is to prefer. The talk ended with examples from my research in Traveler and from our experiences from the Moblogging Jokkmokk Project (here, I mainly referred to Part II of the paper that Stephanie Hendrick and I wrote for BlogTalk 2.0).
Of course the situation itself was very interesting with the notion of presence in mind. I believe that one way of achieving a higher degree of co-presence is by simply creating a dialogue, but as you all know it is difficult enough to get feedback when speaking in front of a larger audience, and I expected that it would be even more difficult here. I had two video links from the class room, but the audience was quite spread out, so I prepared a little experiment for the participants. I asked their teacher to prepare green and red slips of paper, of which the members of the audience received one each. I then instructed them to use these slips to, for instance, answer yes/no or to show agreement/disagreement. This turned out to work quite well, and even though they ended up using them only for answering my questions relating to previous experiences etc. it certainly added a sense of stronger involvement from their part, which made me feel more comfortable as a speaker.
The only thing that went wrong during the presentation was when my screensaver suddenly switched on and my computer was locked. Without thinking about how they maybe still could hear me, I said some well chosen words, only to find out when I returned to the conference that I had been perfectly audible the whole time. On top of it all, we used FlashMeeting for this session, and here, they record everything happening in the video conferencing environment for research purposes, which means that this little incident is even caught on tape
