Stephen van Egmond:

Apple gets a lot of ignorant hate, and a lot of ignorant reverence. Let me give some informed reverence for one area where they kick so much ass: accessibility.

…

I simply gawped when one blind woman pulled out an iPhone then snapped a perfect shot, guided by the built-in Camera app.

Can you believe it, a blind person can use the iOS Camera.app to shoot a decently focused photo?

The magic lies in VoiceOver: “One face. Small face. Face near right edge. Autofocussed.”

You might end up asking yourself why Apple went to such effort to let a blind person take a picture. The only answer I can give is they not only care about making accessible applications: they also actually put in the effort.

Exactly.

There are a few more VoiceOver examples in the linked-post, go check it out.
