BrailleBack lets you connect a supported refreshable braille display to your device via Bluetooth. Screen content is presented on the braille display and you can navigate and interact with your device using the keys on the display. You can also input text using the braille keyboard.
NOTE: These instructions apply to the standard version of Android as found in the Google Nexus range. They also apply to other devices (as long as they are using the same operating system) but please be aware that there may be minor differences. This is due to the custom ‘skins’ some companies apply to their mobile devices instead of the stock Android theme.
