I recently read this paper that thought would be of interest to some of us: Whittaker, S. (2003), ?Things to talk about when talking about things,? Human-Computer Interaction, 18(1-2), 149-170.
It is sort of a basic reveiw paper but it has a nice synthesis and three main conclusions that are relevant to us: a)speech alone is often sufficient for effective conversations; (b) visual information about work objects is generally more valuable than visual information about work participants; and (c) disjoint visual perspectives can undermine communication processes.
Also, towards the end there is this interesting statement about reuse of conversations/interactions, an issue that may gain importance as we transition to a VMT community:
"Although progress has been made in developing visualizations of long-term conversations (Donath et al., 1999; Erickson & Kellogg, 2000; Smith & Fiore, 2001), we currently lack good tools for capturing and distilling conversations for reuse. "
There is also this comment about the importance of supporting different perspectives that I thought was interesting:
"When representing complex visual environments, we need better methods to show others? perspectives when these are notshared, possibly highlighting differences in perspective."
The paper is available through Drexel's Library but I have a PDF if any of you are interested -Johann
