ABSTRACT

This study focuses on the perceptual skills used when playing kendama, a toy with a ball, string, and handle. It examines the visual information required for guiding the head and handle movements during the “swing-in” catching maneuver and determines whether information-based strategies such as canceling the rate of change of α (the optical depression angle from the horizon) or cot α (optical acceleration), using tau coupling, or a combination thereof, could be applied to this empirical task. The regressions of both α and cot α with time are found to be highly linear and increase when the skill level increases. For expert players, the k values for the tau coupling based on the center of the ball are clearly lower than those for the tau coupling based on the hole in the ball compared with skilled players. These results suggest that, with increasing skill level, kendama players tend to utilize α or cot α for regulating the observation point and use the sight of the hole as the tau coupling information for controlling the handle.

在玩Kendama时引导头和手柄运动的光学信息

摘要

这项研究的重点是在玩kendama(一种带有球,线和手柄的玩具)时使用的感知技能。它检查在“摇摆”捕捉动作中引导头部和手柄运动所需的视觉信息,并确定是否基于信息的策略,例如取消α(从地平线向下的光学俯角)的变化率或婴儿床α使用tau耦合(或其组合)的“光学加速度”(光学加速度)可以应用于此经验任务。发现α和cotα随时间的回归是高度线性的,并且随着技能水平的提高而增加。对于专业玩家,k与熟练的运动员相比,基于球中心的tau联轴器的值明显低于基于球中孔的tau联轴器的值。这些结果表明,随着技能水平的提高,kendama玩家倾向于利用α或轻便小床α来调节观察点,并将洞的视线用作tau耦合信息来控制手柄。
