VisTACO: Visualizing Tabletop Collaboration anthony tang, georgiatech michel pahud, microsoft research sheelagh carpendale, university of calgary bill buxton, microsoft research

want: data-driven insight challenge

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 complex challenge

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? analytic tabletop collaboration framework

entities » what is happening to the objects on the table? analytic tabletop collaboration framework

entities » what is happening to the objects on the table? » what are people doing? analytic tabletop collaboration framework

entities » what is happening to the objects on the table? » what are people doing? » what is this person doing? analytic tabletop collaboration framework

temporal » how does collaboration change over time? analytic tabletop collaboration framework

summary spatial global vs. local subject group vs. individual vs. objects temporal aggregate vs. specific analytic tabletop collaboration framework

additional considerations points vs. paths of interaction Scott et al. (2004) Ryall et al. (2004)

additional considerations raw vs. semantic classification of interactions

additional considerations 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

there’s a lot going on! challenge

want: data-driven insight “a lot of centralized interaction” “storage along the side” challenge

q: phases of interaction? case study » 3-way collaboration
