I finally computed old data drawn from CatchBob. The first picture shows our path on the campus. The second depicts the number of area visited (Patrick and I worked on a php file to parse the raw data, then we used R to compute the visualization). As we can see on the second figure, we drew a bounding box that just took into acocunt the area where the players went (this is an issue, we should reconsiderate this because it will not be possible to compare all the groups if we keep this). The third figure shows where player A (above the x axis) and player B (below the x axis) sent their messages.
