In 1821, a soldier visited the school and showed the students a system for passing messages at night during times of battle.
1821年，一名士兵訪問了這所學校，向學生們展示了戰爭期間在夜間傳遞信息的方法。
His system used paper with small, raised dots that could be felt with the fingers.
他的方法使用帶小凸點的紙張，這些小凸點可以用手指感覺出來。
Each letter of the alphabet was represented by a different pattern which consisted of twelve dots.
單詞的每個字母都是由十二個凸點不同排列模式而構成。
The soldiers would drag their fingers over the raised dots to read the message.
士兵用力地拽著學生們的手指感覺凸點，閱讀信息。
While the students found the soldier's idea interesting, the system was too difficult to be of practical use.
雖然學生們都覺得士兵的想法非常有趣，但這一方法太過復雜，并不實用。
However, young Louis Braille took the idea and worked on it.
然而，年少的路易斯·布萊爾接受了這個想法，并開始研究起來。
At the age of fifteen, he created a system with patterns of six raised dots representing each letter.
十五歲的時候，他的系統發明完成了，用六個凸點來組成每一個相應的字母。
'Braille', the system for reading used today by blind people around the world, was thus born.
“布萊爾點字法”，今天世界上盲人看書采用的方法，就此誕生了。
