This Braille keyboard presents itself as a standard Android input method and can be used in any application where a keyboard is displayed to enter text. This enables an experienced Braille typist to exceed the typing speeds of sighted users across all of their applications.

Two keyboard layouts are supported:

A conventional horizontal layout for large screens like tablets and a vertical layout suitable for smaller displays like phones. In both modes you can type using the standard Braille fingers and use convenient gestures to manipulate and read the text input. Both keyboard styles support additional configuration so that you can configure your perfect layout. Both six dot literary and eight dot computer Braille are supported.
