五个实验报告中，受试者匹配有形或可见的盲文字符对视觉或有形阵列。在这两种模式识别受损时，字符倾斜，但视觉性能优于触摸上级。触摸可能比视觉对倾斜更敏感，因为与直立的非常小的偏差会降低识别准确性。方向影响模式识别与没有事先信息的方向。倾斜模式减缓识别触觉视觉匹配，但只有当方向进行了研究，重复的措施。结果是一致的假设，这是很难编码盲文模式触觉作为全球轮廓形状。
Five experiments are reported in which subjects matched tangible or visible braille characters against either visual or tangible arrays. In both modalities recognition was impaired when the characters were tilted, but visual performance was superior to that for touch. Touch may be more sensitive than vision to tilt, since very small deviations from the upright decreased recognition accuracy. Orientation influenced pattern recognition with and without prior information about orientation. Tilting patterns slowed down recognition for tactual–visual matching, but only when orientation was studied with repeated measures. The results are consistent with the hypothesis that it is difficult to code braille patterns tactually as global outline shapes.
