Designing information visualizations for elite soccer children's different levels of comprehension

We describe a study that sought to understand elite soccer children's use of visualizations to learn about, and improve their own sports performance. We specifically investigate how visualizations support the players' data comprehension. In this process, we design and evaluate visualizations based on real data. Finally, we discuss how the players' level of comprehension might depend on factors such as their general literacy and visualization literacy, and the role of visualization in coaching children.
