Computer Braille is an adaptation of braille to an eight-dot cell; the resulting 256 characters are assigned to the 256 characters of ASCII computer coding. Unfortunately, an eight-dot cell is too large to be read easily, negating one of the principal advantages of braille, and it was abandoned in Unified English Braille, which has been adopted in most English-speaking countries apart from the United States.

One quarter of Computer Braille characters are the 64 of standard braille. Capital letters are derived by adding dot 7:

Lower case: ⠁ (braille pattern dots-1) a ⠃ (braille pattern dots-12) b ⠙ (braille pattern dots-145) d ⠅ (braille pattern dots-13) k ⠇ (braille pattern dots-123) l ⠽ (braille pattern dots-13456) y
Upper case: ⡁ (braille pattern dots-17) A ⡃ (braille pattern dots-127) B ⡙ (braille pattern dots-1457) D ⡅ (braille pattern dots-137) K ⡇ (braille pattern dots-1237) L ⡽ (braille pattern dots-134567) Y
