ELI5: How do blind people learn to read Braille?
gpt
Pretty much the same way that people learn to read printed letters/words.  The Braille alphabet is pretty much identical to the one that you are using to read this very passage right now, but represented by a grid of six dots that can be felt rather than just seen.

Once you learn which series of dots represents which letter - bam, you can read braille.
