How I built an audio book reader for my nearly blind grandfather
Hello. I just want to say that you should reconsider iOS-based devices. I am very low vision and can use iOS perfectly well. It has both built in zooming and text-to-speech (VoiceOver). Many apps, including Audible.com, are very accessible and work well with VoiceOver. If you have an iOS device on hand, check out the Settings->General->Accessibility offering or look at this: https://www.apple.com/accessibility/ios/. You should also take a look at applevis.com.You should also check with his local government to see what services are available for the blind and visually impaired. Even with no vision, one can live a happy life and still be an active member of society. All it takes is some help learning how to navigate the world.
