Google has made some great enhancements to the Android platform with the goal of making their devices more user friendly to people with blindness or low-visibility. Google engineers have simplified the process for developers to augment their code to let Android use its accessibility features for these users. These accessibility features utilize either TalkBack (a spoken feedback system), or enable connected devices which give a blind person a legible description of the display to read using BrailleBack (a Braille emulator). TalkBack is already implemented in Android, while BrailleBack is available in the Play Store.
These features were put on display at an “Enabling Blind and Low-Vision Accessibility on Android” presentation at Google I/O. Developers were explained how to optimize their applications to take advantage of Android’s accessibility tools.
