Why does Braille use raised bumps instead of raised letters?

Question

Why not just use the original letters?

In: Technology

Answer 1

I’m not a specialist, but there could be multiple reasons :
It’s easier to recognize a pattern of dots than to recognize a series of straight and curved lines like in a letter.
The Braille letters each have the same width while alphabet letters do not. It’s easier to know when a letter starts and stops.
It’s also much easier to engrave dots on a sheet of paper than regular letters.
Finally, I’d say it’s easier to write Braille letters than to write regular letters if you’re Braille, but I’m not sure about that one.
