This study aimed to test differences in drawn size of familiar objects of different physical size in haptic drawings produced by blindfolded sighted participants. Using two sizes of the foil sheets on which they made convex drawings, they drew one object per foil. The results showed that the size of drawings increased linearly with the rising rank of real-world size. Although larger drawings were created on larger foils than on smaller ones, the ratio of the object drawn size within the foil sheet size did not differ across foil sizes. Hence, canonical size-a phenomenon known so far from studies on the visual domain-revealed here in a task performed in the haptic domain.
本研究旨在测试盲视参与者在触觉绘图中对不同物理尺寸的熟悉物体的描绘尺寸差异。他们使用两种尺寸的箔片进行凸面绘图，每张箔片画一个物体。结果表明，绘图尺寸与真实世界尺寸的等级呈线性增加。虽然较大的箔片上绘制的图形较大，但箔片尺寸内所绘物体的尺寸比例在不同箔片尺寸之间没有差异。因此，在触觉领域的任务中，与视觉领域研究中已知的规范尺寸现象在这里得到了揭示。
