Qualitative analysis representation

Yesterday I attended Jean-Baptiste's lecture about qualitative analysis of human-computer ineraction in the CSCW course. His slides are available here. What I really appreciated is the way JB visually represents the data collected to bring forward relevant information or patterns. For instance, in this example, he picked up one of the critical events that occurred during a study about how students interact with an interactive table:

Why do I blog this? on a different granularity of analysis, I'd like to have this kind of approach in CatchBob!, especially while analyzing specific moments of interaction between players; namely when the participants understand (or not) what their partner(s) is(are) doing and on which information they rely on to predict this. This is definitely one of the core question of my phd research, with an emphasis on how location-awareness can impact this.
