Vo also gives you a rather large dictionary of gestures, including
rotate, three finger swipe, and others. There's a complete list of vo
enabled gestures somewhere on apple's site, though I don't have the
exact url at the moment. Perhaps taking a look at that list may give
you some ideas for other methods for handling your interface.
Apple really has made it simple for visually impaired folks to use a
touchscreen, so I see no reason why you couldn't leverage that in your
own apps. It may be worthwhile, after reviewing the vo gestures, to
petition apple to add something to handle single clicking, as I too
know folks who are motor impaired, and though they can work with the
current setup, it might not be a bad idea to get a few more functions
thrown in just for making life easier for others as well.

Thanks for your idea,
as far as we discussed with the medical staff, we want a tap, but I
will add a lift to the discussion. That said, it seems that "tapping/
pointing" something is the learned real-world gesture, and we are
concerned mostly with elderly people here (Stroke patients).
I realize that what we are doing here is not exactly what VoiceOver
on iOS is for. We are intending to create a very simple user
interface with both visual and auditive feedback, and really we
would be happy to just leverage VoiceOver's Text-To-Speech
capabilities. But as far as I can tell, you can't have that without
activating VO.

I'm not sure how easy it would be to emulate, but the Iphone does
have a touchtyping mode, where the voiceover user can select
letters by touching the screen, and moving around until he/she is
on the letter they require, whereupon lifting the finger "types"
this letter into the current text edit area. Perhaps something
like that would be useful in this case. I'm not sure how limited
your users may be, but some of them may have an easier time lifting
to envoke functions rather than tapping.

Hello List,
I am developing a somewhat unusual iOS app in terms of
accessibility. I am happy to go into details, but my question is
this:
* How do I react to a single tap when VoiceOver is active?
I have tried UITabGestureRecognizer, or overriding touchesBegan/
touchesEnd in my custom view, but both only reacted on a double
tap (as expected in VoiceOver).
However, the users of this app will have very limited motor
abilities, so in this special case they can just select something
by tapping once anywhere on the screen.
Am I missing something obvious here, or is there a trick to it?
Thanks
Alex
