Braille consists of combinations of raised dots that form letters, numbers, punctuation, and abbreviations for common words and letter patterns. Braille was invented by Louis Braille in 1821. Each Braille cell can have up to six raised dots, allowing for sixty-three possible characters. Two main types of Braille are taught. Grade one Braille includes the alphabet, numbers, and basic punctuation. Grade two Braille includes abbreviations, which helps users to read and write at faster rates. According to the American Council for the Blind, “The average reading speed is about 125 words per minute, but greater speeds of up to 200 words per minute are possible.” Technological advancements have allowed for Braille to be more easily typed and printed from electronic sources.
