[BlindMath] Gardner–Salinas braille codes?

[John Gardner]

Bill, this code was developed by Norberto Salinas and me as a unified braille code, not just for math. Unfortunately, our philosophy was rejected (on a 5-4 vote!) by the Unified English Braille Code development committee, resulting in the non-unified UEB. It's a long sad story.

GS is a really good code, but there seems to be no place for it in this world unfortunately. It can be used in Lean Math, but otherwise I know of no use for it. FYI Lean Math will, hopefully soon, become an open source project and become something really useful. To this point it has been something I did in my spare time, but I don't have much spare time, and I am not a very good software developer.

John

Subject: [BlindMath] Gardner–Salinas braille codes?

Hello,
I found this code on Wikipedia: https://en.wikipedia.org/wiki/Gardner–Salinas_braille_codes <https://en.wikipedia.org/wiki/Gardner%E2%80%93Salinas_braille_codes#Set_theory>
However, searching the list archives yields few relevant results. Does anyone here have experience with this system? Do you find it easier to use for personal notes/scratchwork than UEB or the older Nemeth Code? It seems much more compact than the aforementioned systems, allowing for more symbols on one line and more efficient usage especially when working with long expressions. Do you use it with a Braille display or on paper? If the latter, how do you write the 8-dot symbols?

Thanks,
Bill
