排列算法在盲文码表编制中的应用

APPLYING PERMUTATION ALGORITHM IN COMPILING BRAILLE CODE-TABLE

在特殊师范教育的盲文课程教学中,经常需要将盲文和普通文字的混排。在盲文学习中,也经常需要用简单的方法把盲文输入到普通的文档中。目前通过计算机将盲文和普通文字混排,往往采用一些软件来实现,软件的使用有时需要特别的培训。能否有更为便捷的途径?从编制盲文字库输入码表入手,运用排列组合算法编制码表,模拟盲文打字机输入的方式,直接将盲文输入码与计算机键盘结合,使得盲文输入码易学习、易记忆。

In Braille courses teaching of special teachers＇ education, the Braille is often needed to be typeset mixed with normal charac- ters. In their Braille studies, the students of special teachers＇ education also need to input the Braille to general documenis in a simple way. At present, the mixed typesetting of Braille and normal characters usually is implemented with some software, but the use of such software sometimes requires special training. Is there a more convenient way to do that？ In this article we proceed from compiling the Braille letter li- brary inputting code-table, compile the code-table using permutation and combination algorithm, simulate the mode of Braille typewriter＇ s in- put and directly integrate the Braille inputting codes with the keyboard of computer, and facilitate the Braille inputting codes simple to learn and easy to follow.
