History of braille
Louis Braille
"Make the world bright with only 6 points" Louis Braille(1809~1852) lost his sight when he was 4 years old. He accidently poked his eyes with an awl. Although he became blind, he learned to differentiate things by sound, smell, shape and touch. Despite his physical blindness, he didn't lose his inward eye to see the world. He learned history, geography, mathematics, and even music with the help of his parents and teachers not to fall in despair.
With his musical talents, he played piano, organ, violin and cello. Later on he performed a pipe organ in the church.
In 1829, studying at the Paris school of the blind, Braille invented the present braille system in a new way of indicating 26 alphabet letters with 6 points with the instrument of the awl which made him blind. This sort of system and effort later created the braille musical notation. Finally, the invention of 라피그래피? (1839) as a system of dots representing the shape of letters, made the blind to read with fingertips and the low vision people to read the points with his eyes. In this way, the low vision people were able to communicate with each other. In those days, Louis Braille's invention of the braille was not highly appraised but it became well known later as it gave light to the famous disabled people such as Helen Keller and Ray Charles.
Park Duseong
In Korea, Songam Park Doo-Sung created a 6-dot Korean braille and announced it on November 4, 1926, under the name of 'Hunmaengjeongeum'. did.

Braille devices
Traditionally, Braille was printed on Braille paper using a Braille printer, but recently, with the development of assistive technology devices for people with disabilities, portable information and communication devices that can be used without paper and through Braille displays and speech are called Braille information devices. Braille information devices can be connected to a personal computer (PC) and can be used to access Braille documents as well as the Internet.
Examples of Braille devices include the Braille Hansone (South Korea and
Braille Note (New Zealand).
These devices allow blind people to easily and conveniently utilize all the features a computer has to offer, including word processors, calendars, email, calculators, web browsers, file management, and more, and are used for learning, rehabilitation, and access to many information.
