Self-reflection support system for team sports based on reflection perspective classification

The purpose of this study is to support team sport players in their post-match reflections. Reflecting on the match and recognizing points for improvement is important for preventing repeated mistakes and improving the accuracy of decision-making during play. However, in team sports, players need to be aware not only of their individual actions, but also of the situation of the team, such as their positioning according to the development of the match and cooperation between players. And there are many items to consider, and it is not easy to systematically verbalize points for reflection. Therefore, we attempted to solve this problem by developing a system that categorizes the content of reflection into four types and helps participants verbalize their reflections for each item. To verify the usefulness of the proposed system, we focused on soccer, a sport in which players' movements tend to be complex, and observed 12 experienced soccer players as they used the system to reflect on their matches. The results suggested that presenting reflection perspectives contributes to concretizing the content of reflection and promoting reflection from multiple perspectives.
