触觉识别熟悉的物体的早期盲人，晚期盲人，和视力的调查与二维（2-D）和三维（3-D）的刺激产生的小触觉针。2-D刺激是通过将触针升高到1.5 mm来描绘的对象的轮廓。3-D刺激是通过将触针升高到10 mm（对应于对象的高度）来产生的浮雕。在所有三个受试者组中，3-D刺激的正确答案的平均识别时间比2-D刺激的平均识别时间快。对于晚盲组和有视力组，2-D和3-D刺激之间的正确反应百分比没有统计学显著差异，但早盲组表现出显著差异。此外，触觉易读性的质量描述的对象，不管是否刺激被理解，进行了测量。3-D刺激的触觉易读性显着高于所有组的2-D刺激。这些结果表明，3-D演示似乎有望克服2-D图形显示的局限性。
Haptic recognition of familiar objects by the early blind, the late blind, and the sighted was investigated with two-dimensional (2-D) and three-dimensional (3-D) stimuli produced by small tactor-pins. The 2-D stimulus was an outline of an object that was depicted by raising tactor-pins to 1.5 mm. The 3-D stimulus was a relief that was produced by raising the tactors up to 10 mm, corresponding to the height of the object. Mean recognition times for correct answers to the 3-D stimuli were faster than those for the 2-D stimuli, in all three subject groups. No statistically significant differences in percentage of correct responses between the 2-D and the 3-D stimuli were found for the late-blind and sighted groups, but the early-blind group demonstrated a significant difference. In addition, the haptic legibility for the quality of depiction of the object, without regard to whether or not the stimulus was understood, was measured. The haptic legibility of the 3-D stimuli was significantly higher than that of the 2-D stimuli for all the groups. These results suggest that 3-D presentation seems to promise a way to overcome the limitations of 2-D graphic display.
