[BlindTlk] Computer Braille

[Steve Jacobson]

Jesse,

The answers you are getting are confusing because there are really two different codes that we have commonly called the "Computer Code."  In the English Braille American Edition, there was a method to write computer code when it occurred within regular text.  There was a symbol, I believe Dots 456 followed by dots 346 that started computer code.  This code is not preserved as a separate code in UEB and is therefore discontinued.  However, I hate to mention this, but there are probably still books around that use this code.

There is another code that we referred to as a Computer Code which is still commonly used in note-takers and sometimes with braille displays.  It uses certain dot combinations for punctuation that is normally used for certain contractions.  The purpose of this computer code is to have a one to one correspondence between the braille character and the print character.  Because there are only 64 dot combinations, counting the space, it does not cover all characters, though.  However, this code does not depend upon any kind of back-translation so it is particularly used in simpler devices.  

In theory, this code is also replaced to some degree by Unified English Braille, UEB.  The reason is that with careful use, contracted UEB input to a computer can be correctly back-translatedinto correct email addresses, URL's and passwords.  However, there is more.

Even though it is true that one can enter information in contracted UEB braille and have it correctly interpreted by a computer, this depends upon the ability for the UEB input being back-translated into the correct print characters.  Some devices do not support back-translation in password fields, for examples and some note-takers also don't back-translate some fields that might be used in other than text.  Therefore, this second computer code is probably going to be with us for a while.

The computer code that one enters in this scenario isn't too difficult.  Perhaps others here know where one could get a document, but if not, we can probably list out the symbols you will likely need if this is the code you need.  I will see if I can find anything.

Best regards,

Steve Jacobson
