Braille

Braille is a tactile writing system used by people who are blind or visually impaired. It is traditionally written with embossed paper. Braille can also be written with a braille typewriter or computer. There are three main types of braille: • Grade 1 braille is a basic code of letters, numbers, and punctuation marks. • Grade 2 braille is a more advanced code that includes contractions of words and abbreviations. • Grade 3 braille is a highly abbreviated code used for writing memos, notes, and reports. Braille is named after its inventor, Louis Braille, a French educator who lost his sight at the age of three. In 1824, Braille developed a code of raised dots that could be read with the fingertips. This system was later refined and became known as braille. Today, braille is used by people all over the world. It is the official writing system of many countries, including the United States, the United Kingdom, and Australia. If you are interested in learning braille, there are many resources available.
