Two studies are reported in which comprehension and interpretation of raised-line images and graphs by touch were investigated. Experiment 1 required blind-folded sighted subjects and blind subjects to rate the veracity of raised-line drawings in conveying the nature of an image when the complexity of the depicted object was manipulated (from simple outlines to more complex exaggeration of salient features). Results showed no effect of complexity on veracity ratings. Experiment 2 involved the assessment of blind and visually impaired subjects of line-graphs, histograms and pie charts which varied in information content and perceptible detail (textured and untextured). Histograms were easier to interpret than line-graphs, but there were no differences between histograms and pie charts. An increase in information content had little effect on comprehension.
本文报告了两项关于通过触摸来理解和解读凸起线条图像及图表的研究。实验1要求蒙眼的视力正常受试者和盲人受试者在操纵所描绘物体的复杂性（从简单轮廓到对显著特征进行更复杂的夸张）时，对凸起线条绘图在传达图像性质方面的准确性进行评分。结果表明，复杂性对准确性评分没有影响。实验2涉及对盲人和视力受损受试者对线图、柱状图和饼图的评估，这些图表在信息内容和可感知细节（有纹理和无纹理）方面存在差异。柱状图比线图更容易解读，但柱状图和饼图之间没有差异。信息内容的增加对理解影响不大。
