作为足球运动中的一种高水平战术，球队阵型能够给球员分配不同的任务，并指示他们在球场上的活动区域，从而对球队的表现产生重要影响。足球阵型的分析已经成为足球分析师特别不可或缺的。然而，团队的形成本质上是随时间变化的，并且包含固有的空间信息。阵型的时空特性和足球数据的其他特征，如多变量特征，使得足球阵型分析成为一个具有挑战性的问题。在这项研究中，我们与领域专家密切合作，以表征足球中的队形分析领域问题，并制定了几个设计目标。我们设计了一种新颖的团队队形变化的时空视觉表示，使分析师能够直观地分析队形的演变，并跟踪随时间变化的队形内的球员的空间流。在新设计的基础上，我们进一步设计和开发了ForVizor，这是一个视觉分析系统，使用户能够跟踪地层的时空变化，并了解这些变化是如何以及为何发生的。通过ForVizor，领域专家对两个游戏进行了阵型分析。两个案例研究总结了包含见解和有用反馈的分析结果。
Regarded as a high-level tactic in soccer, a team formation assigns players different tasks and indicates their active regions on the pitch, thereby influencing the team performance significantly. Analysis of formations in soccer has become particularly indispensable for soccer analysts. However, formations of a team are intrinsically time-varying and contain inherent spatial information. The spatio-temporal nature of formations and other characteristics of soccer data, such as multivariate features, make analysis of formations in soccer a challenging problem. In this study, we closely worked with domain experts to characterize domain problems of formation analysis in soccer and formulated several design goals. We design a novel spatio-temporal visual representation of changes in team formation, allowing analysts to visually analyze the evolution of formations and track the spatial flow of players within formations over time. Based on the new design, we further design and develop ForVizor, a visual analytics system, which empowers users to track the spatio-temporal changes in formation and understand how and why such changes occur. With ForVizor, domain experts conduct formation analysis of two games. Analysis results with insights and useful feedback are summarized in two case studies.
