Fabrice (the master student I work with) has just completed another step in the replay tool project. The point of this is to have a tool that help us to replay the CatchBob! pervasive game so that I can use it with participants to gather information about their activity, what happened, etc. In the last version, it's possible to have a replay of each players' path (in the bottom left-hand corner hereafter) plus some visualizations like the distance between 2 players (in the bottom right hand corner) or the evolution of the group dispersion (in the upper right hand corner). This can be interesting to understand the players' behavior while performing the activity.
