This is great news for people who want to use Braille input on androiad devices, but old news for iOS. Apple added Braille Screen Input with iOS 8 in 2014.
I hope that Android's implementation of this will work as well as Apple's offering. I know blind people who can enter text quickly with Brialle screen input on iPhones and iPads.
