Braille invented the raised dot alphabet to give blind people the ability to read by touch.
There are 256 possible combinations of dots in 8-dot braille (if you include a blank cell as a character).
One raised dot equates to the letter "A" ; see related link to additional information concerning Braille .
The simplest depiction of a number system is with a system of dot groupings similar to braille. This is critical to the function of a quantum computer.
dot system
Louis Braille, a blind Frenchman, invented the embossed dot system of reading and writing for the blind in 1824. His system revolutionized communication and accessibility for the visually impaired, allowing them to read through touch.
He invented Braille, a system of raised-dot writing so blind people could read using their finger-tips.
Louis Braille was inspired to create the Braille system by Charles Barbier's night writing system for military communications. Initially designed using raised dots in a six-dot cell, Braille further developed and simplified the system into the current form we know today to help visually impaired individuals read and write independently.
The first Braille Bibles were printed in the mid-19th century. Louis Braille, who invented the raised dot system for blind readers, conceived the idea of a Braille Bible and it was eventually produced in 1837.

The Braille system is used to represent written text identified by touch rather than by sight. It consists of a 2-by-3 dot cell, where dots are raised according to predefined character patterns. A similar system was developed for the French army, with 12 dots per cell, but was never used. Louis Braille, who was blind, was inspired by the 12 dot system but simplified it so that an entire cell could be read without moving the reading finger. Devised in 1825.

The single dot in braille represents 'A'
First of all the inventor of braille is Louis braille he invented braille cause he was blind and wanted other blind people to read so for each letter he poked a dot to feel which made a letter
Louis Braille didn't learn to read or write at his first school because they didn't have any accommodations for blind students. The school mainly focused on oral instruction and didn't have any tactile methods for blind students to learn. It wasn't until Louis Braille transferred to the Royal Institute for Blind Youth in Paris that he was exposed to the raised dot system that he later developed into braille.
