Six-dot braille cell
VocabularyA traditional braille cell has six positions that can each be raised or unraised.
Explanation or usage
Six independent two-state positions provide 64 possible patterns when the all-unraised pattern is included. Actual meanings depend on the braille system and context, and not every pattern is an alphabet letter. This refers to traditional six-dot braille; eight-dot systems also exist.
Common misunderstandings
All 64 patterns are distinct letters, or every braille system uses six dots.
