追逐和逃跑行为是许多运动项目中的重要技能。以前的研究已经描述了攻击者（逃跑者）和防御者（追赶者）的行为，重点是他们的位置关系，并提出了几个关键参数，影响结果（成功的攻击或防御）。然而，目前尚不清楚每个个体代理如何移动，以及在这种类型的相互作用中如何确定结果。为了解决这些问题，我们在虚拟空间中构建了一个追逐和逃跑任务，允许我们操纵代理的运动参数。我们确定了每个代理的基本策略及其对参数变化的鲁棒性。此外，我们确定了结果的决定因素和几何解释其重要性。我们的研究结果揭示了一个简化的人类追逐和逃跑互动的基本结构，并提供了这样一种见解，即虽然每个代理显然是自由移动的，但他们在两个代理互动中的策略实际上是相当受约束的。
Chase and escape behaviors are important skills in many sports. Previous studies have described the behaviors of the attacker (escaper) and defender (chaser) by focusing on their positional relationship and have presented several key parameters that affect the outcome (successful attack or defense). However, it remains unclear how each individual agent moves, and how the outcome is determined in this type of interaction. To address these questions, we constructed a chase and escape task in a virtual space that allowed us to manipulate agents’ kinematic parameters. We identified the basic strategies of each agent and their robustness to changes in their parameters. Moreover, we identified the determinants of the outcome and a geometrical explanation of their importance. Our results revealed the underlying structure of a simplified human chase and escape interaction and provided the insight that, although each agent apparently moves freely, their strategies in two-agent interactions are in fact rather constrained.
