We examined the role of visually controlled movement in a two skilled task, drawing and a Bilboquet trick "Swing-in."In a first study on a blank sheet of paper, two painters were asked to draw a bronze figure of a foot. Both the picture on the paper and the movement of the painters were recorded by digital video camera and 3D motion capture system. Using RQA strategies, the dynamical properties of the movement of the painters were quantified. It was found that the movement of the head to shift gaze between the figure and the paper, and the movement of the hand holding a pencil was reciprocally coupled in such a way not to be dysfunctional to each other.In a Bilboquet task, four expert and four novice players performed 200 trials. The expert's head and knee movements were more extensive and the couplings of the head and the ball, the knee and the ball were tighter in the experts than the novice's. And at the end of each trial, distances between the head and the ball in the expert group were more consistent than that in the novice group. These findings suggest that Bilboquet experts control their body movement to dynamically coordinate their body with the moving ball and the strong coupling of the head and the ball in the experts seemed to contribute the stabilization of their vision.

我们研究了视觉控制运动的作用，在两个熟练的任务，绘图和Bilboquet技巧“摆动。在第一项研究中，两名画家被要求在一张白纸上画一只脚的青铜雕像。无论是纸上的图片和画家的运动都是由数码摄像机和3D运动捕捉系统记录下来的。使用RQA策略，画家的运动的动力学特性进行了量化。结果发现，头部在人物和纸张之间移动视线的动作，以及拿铅笔的手的动作，是以一种不会相互失调的方式耦合在一起的。在一个比尔博奎特任务中，四名专家和四名新手玩家进行了200次试验。专家的头部和膝盖的运动更广泛，头和球，膝盖和球的耦合更紧密的专家比新手的。在每次试验结束时，专家组的头与球之间的距离比新手组更一致。这些研究结果表明，Bilboquet专家控制他们的身体运动，动态地协调他们的身体与移动的球和头部和球的强烈耦合的专家似乎有助于他们的视觉稳定。
