iOS devices are an excellent choice for visually impaired users. They’re portable, they’re fully self-contained and are designed to be used without external peripherals, and the iOS user experience is very functionally concise and goal-oriented. iOS will not present a proliferation of windows, toolbars and minuscule user interface elements. For the most part, they’re comprehensible, focused, and as intuitive as possible. These are all ideal qualities for accessible software, and indeed for software in general.
The question then becomes how we, as developers, can ensure that our applications are as accessible as possible, and that VoiceOver can provide the best assistance. The good news is that it’s incredibly easy to add accessibility support to your application (there’s no bad news, incidentally).
I’ve never spent much time thinking about visually impaired users when it comes to iOS devices, but Apple’s VoiceOver solution really is incredible.
