How to set up braille keyboard on an Android phone
Braille, traditionally, is a system of raised dots that make reading and writing accessible to the blind or visually impaired. While there are external devices that make it possible to type something in braille on a phone, it’s not exactly quick or a seamless experience. With that in mind, Google made the TalkBack braille keyboard. It’s a virtual braille keyboard integrated directly into Android.
Here’s how Google describes the feature:
Our team collaborated with braille developers and users throughout the development of this feature, so it’ll be familiar to anyone who has typed using braille before. It uses a standard 6-key layout and each key represents one of 6 braille dots which, when tapped, make any letter or symbol. To type an ‘A’ you would press dot 1 and to type a ‘B,’ dots 1 and 2 together.
