盲文又称点字、盲字、凸字,是盲人使用的文字,由法国人路易·布莱叶发明,透过盲文板、盲文机、盲文打印机等在纸张上制作出不同组合的凸点而组成。盲文的基本单位是长方形的盲符,有位置固定的六个点,每个点可以凸出或不凸出,形成64种可能。六个点的分布是左右两行,上中下三层。如图所示,左行自上而下称为1、2、3点,右行自上而下称为4、5、6点。在电脑的使用范畴内,盲人可以配合盲文显示机将萤幕上的文字即时转化成盲文;而为了能表达ASCII的所有符号,故有增至八点的盲文产生。
布莱尔盲文由63个编码字符组成,每一个字符由1~6个突起的点儿安排在一个有6个点位的长方形里 。为了确认63个不同的点式或盲文字符,数点位时是左起自上而下1—2—3,然后右起自上而下4—5—6。这些凸起在厚纸上的行行盲文,可以用手指轻轻摸读。
由于中文字是方块字,包含多种笔划,故中文盲文都是以盲文拼音,不同方言有个别的盲文系统。显然,中文盲文的缺陷便是容易造成同音异字的混淆。另一个问题,是盲人由于缺乏对汉字的训练,会对汉字一无所知。例如在香港,不少盲人只懂得讲或打盲文而不会写字,就是这个原因。阿拉伯数字表示法有布莱叶和安托万两种。布莱叶式比较常用,英语盲文、汉语盲文等众多盲文都使用这种形式;安托万式主要用于法语盲文。布莱叶式用前十个字母表示1到0,安托万式的1-9是在布拉耶式基础上加6点,安托万式的0是布拉耶式的数字符号。
