Answer 1

Braille:

• Hauy created a system of reading for the blind as a result of this idea. He used relief printing so that the ordinary letters could be touched with the finger.
• He discovered how to achieve his highest aspirations with the help of one tutor, Monsieur Andre Pigner.
• The "night writing" approach developed by Barbier is based on a raised 12-dot cell that is two dots wide and six dots tall. Each dot in a cell, or group of dots, indicated a letter or a phonetic sound.
• He created the name-bearing universal reading and writing system at the age of 15 for use by blind or visually impaired individuals. In 1829, at the age of 20, he released the first Braille book, Method of Writing Words, Music, and Plain Songs by Means of Dots, for Use by the Blind and Arranged for Them.
• Braille's approach was to employ 6-dot cells and give each letter of the alphabet a unique pattern. Additionally, Braille created symbols to represent punctuation and numbers.
• Louis Braille, a Frenchman who developed Braille and was blinded in an accident as a youngster, is the name given to the writing system. He created a code for the French alphabet in 1824, when he was only fifteen years old, to replace night writing.
