Laura, Interesting. I did find one of theirs also and tried it and as Jonathan states, it was very hard to hear, the audio quality was extremely poor. For a blind user, they did not give enough time between hearing what they say and hearing what the screenreader says back as I keyed in the prompted letters. I just thought that they might have implemented something that would be something to look at and be of value. Their own writeup sounded like they put a lot of design thought in to it. Perhaps for blind users , yes, but not for low vision users.

It still does not work. A person is still presented with distorted photos to identify. No audio option is available.
