VisTACO: Visualizing Tabletop Collaboration

anthony tang, georgiatechmichel pahud, microsoft researchsheelagh carpendale, university of calgarybill buxton, microsoft research

want: data-driven insightchallenge

is our tabletop system good?

“collaboration” metrics

working together? working independently?

how is space being used?

how does interaction change over time?

challenge

tabletop collaboration is complexchallenge

overview

an analytic framework for tabletop collaboration

vistaco: the first iteration

partial demo

example: distributed tabletop collaboration

toward an analytic tabletop collaboration framework…

what are important factors to study and consider?

spatial aspects of work

» where are people working?

» who works in this space?

additional considerations

points vs. paths of interaction

Scott et al. (2004)Ryall et al. (2004)


raw vs. semantic classification of interactions


multitouch and user identification

message

visualizations of collaboration data can give us insights that might be otherwise difficult to spot—particularly patterns of interaction

VisTACO is a visualization system that aids the analysis of tabletop collaboration
