Tactile Syllabary

There is a tactile syllabary for use by blind and visually-impaired language users.

Each cell is three rows by two columns of raised dots. The upper four dots generally denote the consonant, with syllables beginning with b, d, j, g, f, or x being the exceptions. The lowest pair generally denote the vowel.

Dot 5 (⠐) by itself is the geminate. Word separation is shown by (⠀) an empty space, clause separation by (⠤) the comma, and sentence separation by (⠔) the period. Numbers are prefixed with (⠨) the number sign, and the first syllable of each number is used.
