Braille is a tactile writing system used by people who are visually impaired. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser.

A writing system comprises a particular set of symbols, called a script, as well as the rules by which the script represents a particular language. Writing systems can generally be classified according to how symbols function according to these rules, with the most common types being alphabets, syllabaries, and logographies. Alphabets use symbols called letters that correspond to spoken phonemes. Abjads generally only have letters for consonants, while pure alphabets have letters for both consonants and vowels. Abugidas use characters that correspond to consonant–vowel pairs. Syllabaries use symbols called syllabograms to represent syllables or moras. Logographies use characters that represent semantic units, such as words or morphemes.
Written Chinese uses morphosyllabic characters assembled from phonetic and semantic components in order to encode the spoken language
