Football Tactics 8 Analysis of Open Tracking Data

The open tracking data analyzed in this book is observed in a mini-game format (8 vs. 8, a half coat, 30 minutes half). The author is grateful to Dr. Mutschler and to the committee of The International Conference on Distributed Event-Based Systems held in 2013.

In chapter 3, described is an elementary analysis. Several steps are necessary to apply analysis results for coaches' decisions. An attempt for such steps is three indexes for detecting off-the-ball movements in chapter 4. In chapter 5, the author described restrictions of the Voronoi diagrams in the football analysis. The Voronoi diagrams in the football games show consistent personal areas, at a glance. However, one must understand assumptions that the Voronoi diagrams include in the football analysis.
