本文报告了两个实验，设置来检查用于取代立方体的长度（L-c），质量（M-c）和密度（ML 3）不同的首选人类的夹具配置。特别地，作者试图提供物体和手之间的尺寸关系的摩尔精确测试，该测试先前已被示出用于预测用于将物体从一个位置运输到另一个位置的抓握配置。实验在2组物体条件下检查了2个抓握过渡（从3个手指到4个手指和从1只手到2只手）。在实验1中，使用具有低密度和小尺寸增量（1 mm）的立方体，而在实验2中，使用具有2个固定尺寸和小质量增量的立方体。结果表明，人体尺度方程K = logL（c）+（logM（c）/a + bM（h）+ cL（h））是预测物体移动时抓握结构的人体尺度信息，其中M-h和L-h是手的质量和长度的人体测量值，a、B和c是经验常数。
This article reports two experiments that were set up to examine the preferred human grip configuration used to displace cubes that varied in length (L-c) mass (M-c), and density (ML3). In particular, the authors sought to provide a mole precise test of a dimensional relation between the object and the hand that had previously been shown to predict the grip configuration used to transport an object from one location to another. The experiments examined 2 grip transitions (from 3 digits to 4 digits and from 1 hand to 2 hands) within 2 sets of object conditions. In Experiment 1, cubes with a low density and a small increment in size (1 mm) were used, whereas in Experiment 2, cubes with 2 fixed sizes and small increments in mass were used. The results showed that the body-scaled equation K = logL(c) + (logM(c)/a + bM(h) + cL(h)), where M-h and L-h are the anthropometric measures of the hand mass and length and a, b, and c are empirical constants, is the body-scaled information that predicts the grip configurations used to displace objects.
