2. want: data-driven insight challenge

3. is our tabletop system good? “collaboration” metrics working together? working independently? how is space being used? how does interaction change over time? challenge

4. tabletop collaboration is complex challenge

5. overview an analytic framework for tabletop collaboration vistaco: the first iteration partial demo example: distributed tabletop collaboration

6. toward an analytic tabletop collaboration framework… what are important factors to study and consider?

7. spatial aspects of work » where are people working? » who works in this space? analytic tabletop collaboration framework

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

41. additional considerations raw vs. semantic classification of interactions

42. additional considerations multitouch and user identification

43. 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

47. there’s a lot going on! challenge

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