Braille is a communication system intended to help visually-impaired people how to read, through decoding words that are recorded on paper using their sense of touch. The system was published in 1829 by the creator of the same name, a visually-impaired, 20-year-old man named Louis Braille. The system is based on raised marks on paper that can be felt by touching them with your fingertips. The raised marks are printed with a special printer, and modern computer software can translate any written material into Braille. You can find more information at (website address).
