Fencing is a sport that relies heavily on the use of tactics. However, most existing methods for analyzing fencing data are based on statistical models in which hidden patterns are difficult to discover. Unlike sequential games, such as tennis and table tennis, fencing is a type of simultaneous game. Thus, the existing methods on the sports visualization do not operate well for fencing matches. In this study, we cooperated with experts to analyze the technical and tactical characteristics of fencing competitions. To meet the requirements of the fencing experts, we designed and implemented FencingVis, an interactive visualization system for fencing competition data.The action sequences in the bout are first visualized by modified bar charts to reveal the actions of footworks and bladeworks of both fencers. Then an interactive technique is provided for exploring the patterns of behavior of fencers. The different combinations of tactical behavior patterns are further mapped to the graph model and visualized by a tactical flow graph. This graph can reveal the different strategies adopted by both fencers and their mutual influence in one bout. We also provided a number of well-coordinated views to supplement the tactical flow graph and display the information of the fencing competition from different perspectives. The well-coordinated views are meant to organically integrate with the tactical flow graph through consistent visual style and view coordination. We demonstrated the usability and effectiveness of the proposed system with three case studies. On the basis of expert feedback, FencingVis can help analysts find not only the tactical patterns hidden in fencing bouts, but also the technical and tactical characteristics of the contestant.

击剑技术和战术特性的可视化

击剑是一项非常依赖战术运用的运动。然而，大多数现有的分析围栏数据的方法都是基于难以发现隐藏模式的统计模型。与网球和乒乓球等连续游戏不同，击剑是一种同时进行的游戏。因此，现有的运动可视化方法不适用于击剑比赛。在这项研究中，我们与专家合作分析了击剑比赛的技战术特点。为了满足击剑专家的要求，我们设计并实现了击剑比赛数据的交互式可视化系统FencingVis。首先通过修改条形图将回合中的动作序列可视化，以揭示双方击剑手的步法和刀法动作。然后提供了一种互动技术来探索击剑运动员的行为模式。战术行为模式的不同组合进一步映射到图模型，并通过战术流图进行可视化。这张图可以揭示双方击剑手采用的不同策略以及他们在一场比赛中的相互影响。我们还提供了一些协调良好的视图来补充战术流程图，从不同的角度展示击剑比赛的信息。协调良好的视图旨在通过一致的视觉风格和视图协调与战术流程图有机地结合起来。我们通过三个案例研究证明了所提议系统的可用性和有效性。在专家反馈的基础上，
