Various object properties are perceptible by wielding. We asked whether the dynamics of wielding differed as a function of the to-be-perceived property. Wielding motions were analyzed to determine if they differed under the intention to perceive or not perceive rod length (experiment 1), to perceive object height versus object width (experiment 2), and to perceive the length forward of where the rod was grasped versus the position of the grasp (experiment 3). Perceiving these different properties is known to depend on different components of the object's inertia tensor. Analyses of the subtle recurrent patterns in the phase space of the hand motions revealed differences in wielding across the different perceptual intentions. Haptic exploratory procedures may exhibit distinct exploratory dynamics.
通过挥舞可以感知各种物体属性。我们询问了挥舞的动态是否因待感知属性的不同而有所差异。对挥舞动作进行了分析，以确定在有意感知或不感知杆的长度（实验1）、感知物体高度与物体宽度（实验2）以及感知杆被握持位置前方的长度与握持位置（实验3）的情况下，动作是否存在差异。已知感知这些不同属性取决于物体惯性张量的不同组成部分。对手部动作相空间中微妙的循环模式进行分析后发现，不同感知意图下的挥舞存在差异。触觉探索程序可能会表现出不同的探索动态。
