Dear Catherine, I realize that you can use either 6 or 8 dot braille on a braille display, but I have never liked using 8 dot braille. I didn't realize other codes besides computer braille used 8 dot braille. If 8 dot braille becomes common usage, then braillers and slates would have to change, too, so blind people could write braille manually. Perhaps some people need 8 dot braille, but I don't.

The fact is that its use allows people to identify more than the 63 characters presented in literary Braille. I forget the precise number of characters available by using 8 dotss--maybe 256 maybe more. As the number of print symbols visible in all types of print lieterature increases, literary Braille will be forced to accommodate this factor. *-dot Braille is one choice. Besides this, two alternative Braille codes exists--DotsPlus by John Gardner and NUBS by Dr. Abraham Nemeth, author of the Nemeth Code. Since there are more than 63 print characters in daily use, 8-dot Braille is one of the possible solutions.
