压纹莫尔斯电码和盲文的触觉感知：视觉和触觉的结合。

在三个实验中，观察者对有形的浮雕图案进行了视觉匹配。使用彩色玻璃模糊视觉，从而评估触觉探索的视觉引导对符号识别准确性的影响。彩色玻璃使浮雕代码不可见，但可以看到手。在第一个实验中，受试者识别了从摩尔斯电码中绘制的点和线组成的模式；在第二个和第三个实验中，他们研究了盲文。结果表明，当提供视觉引导时，受试者在“阅读”有形代码时更加准确。盲文比莫尔斯电码的表现更好。视觉通过提供参照系和扫描运动的视觉来辅助触摸。视力正常的观察者能够通过观察其他人触摸这些符号来识别看不见的盲点，这表明视觉在动觉模式中的重要性。
In three experiments observers made visual matches to tangible embossed patterns. Stained glass was used to blur vision and thus allow the effect of visual guidance of tactual exploration on the accuracy of symbol recognition to be evaluated. Stained glass rendered the embossed code invisible, but allowed sight of the hand. In the first experiment subjects identified patterns made up of dots and dashes drawn from Morse code; in the second and third experiments they studied braille. The results show that subjects are more accurate in ‘reading’ tangible codes when provided with visual guidance. Performance was higher for braille than for Morse code. Vision aided touch through the provision of a frame of reference and through sight of scanning movements. Naive sighted observers were able to identify invisible braille dots by watching other individuals touch the symbols, suggesting the importance of vision of kinesthetic patterns.
