About Braille American Braille Basics by David Holladay and Jesse Kaysen Braille is a system of reading and writing for blind individuals. The basic unit of braille is the braille cell. There are many more inkprint symbols than the 64 braille symbols. For example, most computer systems handle about 96 different inkprint symbols. Braille can show a wide number of different inkprint symbols by using one or more braille cells for each inkprint symbol.
Braille only has one set of letters.
By itself, a braille letter is assumed to be in lower case. To show an uppercase word, you put two capitalization indicators in front of the word. This symbol comes just before the number. An important thing to realize about braille is that you cannot write the dot patterns smaller or larger. The Braille Planets cause braille volumes to be much bulkier than inkprint.
