BrailleBack is an Accessibility Service that helps blind users make use of braille devices. It works together with the TalkBack app to give a combined braille and speech experience.
BrailleBack is not active by default. To turn it on and establish a Bluetooth connection between the Focus and an Android device, do the following:
Once the Focus has been paired, if you power on the display before taking the Android device out of standby, the display will automatically connect. Remember to lock the device before turning off the Focus to ensure that braille auto detection works properly the next time you want to use braille.
The following sections list BrailleBack commands that can be performed from the Perkins-style keyboard as well as other controls on the Focus Blue displays.
