标题： Study of movement coordination in human ensembles via a novel computer-based set-up

摘要： 在当前文献中，人类群体中的运动协调研究较少。在现有的实验工作中，已经研究了所有参与者通过直接视觉和听觉耦合相互连接的情况，以及社会互动如何影响他们的协调。在这里，我们通过一种新的基于计算机的设置来研究人类群体的协调，该设置使个体能够远距离协调彼此的运动，从而最小化社会互动的影响。所提出的平台使得可以在玩家之间实现不同的视觉交互模式，从而使参与者考虑其他人的指定子集的运动。这允许评估玩家之间互连结构及其自身动力学对协调的独占影响。我们的设置还可以部署虚拟玩家，以研究人类与虚拟代理之间的二元交互，以及人类和虚拟代理混合团队中的群体同步。我们使用这种新颖的设置，在不同互连结构下，有无虚拟代理的情况下，研究双人和群体中的协调。我们发现，在双人交互中，虚拟玩家能够以类似人类的方式与参与者进行交互，从而确认了之前工作的发现。我们还观察到，在群体交互中，没有直接视觉和听觉耦合时，人类之间的协调水平取决于参与者的互连结构。这证实了最近文献中提出的观点，即在存在和不存在社会互动的情况下，不同的协调水平在不同的视觉配对中实现。我们展示了在人类群体中部署虚拟计算机代理对群体协调影响的初步实验结果。 显示英文摘要

摘要： Movement coordination in human ensembles has been studied little in the current literature. In the existing experimental works, situations where all subjects are connected with each other through direct visual and auditory coupling, and social interaction affects their coordination, have been investigated. Here, we study coordination in human ensembles via a novel computer-based set-up that enables individuals to coordinate each other's motion from a distance so as to minimize the influence of social interaction. The proposed platform makes it possible to implement different visual interaction patterns among the players, so that participants take into consideration the motion of a designated subset of the others. This allows the evaluation of the exclusive effects on coordination of the structure of interconnections among the players and their own dynamics. Our set-up enables also the deployment of virtual players to investigate dyadic interaction between a human and a virtual agent, as well as group synchronization in mixed teams of human and virtual agents. We use this novel set-up to study coordination both in dyads and in groups over different structures of interconnections, with and without virtual agents. We find that, in dual interaction, virtual players manage to interact with participants in a human-like fashion, thus confirming findings in previous work. We also observe that, in group interaction, the level of coordination among humans in the absence of direct visual and auditory coupling depends on the structure of interconnections among participants. This confirms, as recently suggested in the literature, that different coordination levels are achieved over diverse visual pairings in the presence and in the absence of social interaction. We present preliminary experimental results on the effect on group coordination of deploying virtual computer agents in the human ensemble.
