Abstract: An arrangement to permit blind persons to ''''read'''' printed characters by converting such characters into audible analog signals. Means are included for detecting the presence or absence of characters, their size, shape and orientation, and their grouping into words, sentences or paragraphs. Each of these identifying parameters is translated by electro-optical responsive equipment into distinctive and audible tonal sounds which are associated by the ''''reader'''' with the corresponding printed materials, thus allowing continuous comprehension of the materials.

Abstract translation: 允许盲人通过将这些字符转换为声音模拟信号来“读取”打印字符的安排。 包括用于检测字符的存在或不存在，其大小，形状和方向以及它们分组成单词，句子或段落的手段。 这些识别参数中的每一个都被电光响应设备转换为与“读者”与相应的印刷材料相关联的独特和可听的音调声音，从而允许对材料的连续理解。
