Well, I guess we would need that machine...
No, we shouldn't need the machine. We only need the specification for the 8-dot braille it produces.
Braille has been extended to an 8-dot code, particularly for use with Braille embossers and refreshable Braille displays. In 8-dot Braille the additional dots are added at the bottom of the cell, giving a matrix 4 dots high by 2 dots wide. The additional dots are given the numbers 7 (for the lower-left dot) and 8 (for the lower-right dot). Eight-dot Braille has the advantages that the case of an individual letter is directly coded in the cell containing the letter and that all the printable ASCII characters can be represented in a single cell. All 256 (28) possible combination of 8 dots are encoded by the Unicode standard. Braille with six dots is frequently stored as Braille ASCII.
So I thought perhaps we might simply drop the fourth row if all it contains are alternate versions (e.g. capitals) of the text.
Using the following links:
http://www.brailleauthority.org/http://www.dotlessbraille.org/displays.htmhttp://en.wikipedia.org/wiki/Braille_Asciihttp://acharya.iitm.ac.in/disabilities/asc_brl.php...I converted J-Banner 7 to text as if it were normal 6-dot braille. I simply dropped the fourth row of dots. Here is what results:
GLYPH # | DOTS | BRAILLE ASCII | LITERARY BRAILLE |
01 | 1-2-6 | < | gh |
02 | 1-2-4-5-6 | ] | er |
03 | 2-4-5 | J | j |
04 | 2-3-4 | S | s |
05 | 1-3-5-6 | Z | z |
06 | 1-2-3-4-6 | & | and |
07 | 1-2-4-5 | G | g |
08 | 4-5 | ^ | [contraction prefix] |
09 | 2-3-4-6 | ! | these |
10 | 2-4-5 | J | j |
11 | 1-2-3-4-6 | & | and |
12 | 1-2-4-5-6 | ] | er |
13 | 1-5-6 | : | wh |
14 | 1-3-5 | O | o |
So, yeah. "Gherjsz" to you, too, Bungie. Onward to the 8-dot spec.
any computer braille displays indicate capital letters with a dot on the lower left (dot 7). There is little consistency in the use of the lower two dots. There are a number of official and semi-official 8 dot Braille codes, mostly in Europe. Very little literature has been reproduced in any 8 dot Braille code.
The website quoted above (
http://8dotbraille.com/) provides a totally different method of decoding. The bad news is that the very first 8-dot glyph we find in J-Banner 7 has no mapped value in 8-dot unified! (3-4-7 according to their dot numbering scheme) Maybe I missed something, but I did not find this pattern in their lists of
letters,
numbers,
punctuation, or
symbols.
I looked further. This
article (
http://www.brailleauthority.org/eightdot.pdf) is a great overview of Braille development and includes 8-dot systems. From this, I discovered ISO/TR 11548 which defines an 8-dot braille encoding method for computer use. And you know what? For $157 you can purchase that document from Amazon.com. The ISO site itself has a shopping cart application which they use to SELL you the standards documents.
So let me get this straight. If I'm a blind person who wants to read 8-dot braille, I need to pony up over $100 to purchase a document
NOT PRINTED IN BRAILLE in order to figure it out?!? Sure, I understand that these documents cover the technical aspects of character encoding, blah, blah, blah, and the standards folks have to be reimbursed for their fancy French lunches as they sit in board rooms and vote on the acceptance of new proposals. That doesn't stop me from wanting to whack them upside their heads with a stale loaf of french bread for selling overpriced digital copies of what are supposed to be International Standards. Ok, flame off.
Anyhow, we're striking out (once again) on decoding this banner.
I might as well toss out another idea I had while we're on the topic of failed attempts: "BARRETT" as the key. I reasoned that since the J-Banners have rows of 28 dots and this number is evenly divisible by 7 (go figure) then the seven-character string "BARRETT" (revealed to us in-game though binary) might be the first word encoded in one of the J-Banners. This seemed logical to me: use an established encoding method (binary) to give us the means to decode your own custom encryption method (J-Banner dots.) Sounds fun and exciting, right?
If this were true, then perhaps the first group of four dots in one of the J-Banners is meant to decode to a "B", the second four an "A", the third and fourth four an "R", etc. If there was indeed a one-to-one mapping between the dot patterns and the characters, then we should observe a repeating dot pattern for the doubled letters in "BARRETT", namely the "RR" and the "TT". I don't see this pattern in any of the banners. Please feel free to check into this yourself and prove me wrong.
Finally, in case anyone is wondering "Why does he bother posting all of this stuff if it turns up nothing?"
1: To record that it has already been tried, how it was attempted, and what the results were so that others can save time.
2: For others to correct if I made a mistake or otherwise misinterpreted the data or the decoding processes.
There are still some leads in the Braille department. As the
aforelinked article describes, there are Braille encoding methods for music and math, for example. For now, though- I am spent. My shift is over. Next?
