If you have iOS 14.7 or later, it is now possible for you to translate something written in Unified English Braille(UEB) using a new free app.
Braille scanner allows you to take a photo of a paper with braille on it ,using your iPhone and within seconds it is translated to text.
During the launch, the developer , Aaron Stephenson said,
"Braille Scanner was created to help transcribe from Braille to text. It uses a combination of machine learning and vision to do this. The current transcribing model uses Unified English Braille, grade 1, and I'm planning on adding more in the coming app updates".
