在这篇论文中，我们分析了单手握握手势传达物体的高度或形状。分析包括(1)区分每个手势中手的哪些部分是轮廓，(2)考虑这些部分是否被其他手指遮挡，以及(3)从(1)和(2)中得出哪些手的形状特征有利于身高或形状手势的预测。在一个生产实验中，我们要求参与者只用食指和拇指指出一个小球的高度或形状。不出所料，中指、无名指和小指更倾向于卷起来表示身高。对于形状手势，这三个手指更翘。在两个感知实验中，参与者通过电脑生成的连续的手形刺激来观察虚拟的手。我们发现，如果中指、无名指和小指更向内卷曲，参与者更有可能将一个手势理解为表明身高。我们的研究结果提出了新的问题，即手势的物理形式与推断的想象形式之间的关系，这些形式涉及从手势中推导意义。
In this paper, we analyze single-handed hold gestures that convey either the height or the shape of an object. The analyses include (1) differentiating which parts of the hands are profiled in each gesture, (2) considering whether these parts are occluded by other fingers, and (3) deriving predictions from (1) and (2) with regard to what hand shape characteristics favor height or shape gestures. In a production experiment, we asked participants to indicate either the height of a small ball or its shape, using only the index finger and the thumb. As predicted, the middle, ring and little finger were more curled in for height gestures. For shape gestures, those three fingers were more raised. In two perception experiments, participants viewed virtual hands from a computer-generated continuum of hand-shape stimuli. We found that if the middle, ring and little finger were more curled in, participants were more likely to interpret a gesture as indicating height. Our results pose new questions with regard to the relation between the physical form of a gesture and the inferred imaginary forms that are involved in deriving meaning from a gesture.
