I haven't experienced it either, although I don't consider myself an experience iPhone user. I agree those who are experiencing the problem should be as detailed as possible when reporting their issue. I just think it's a mistake to assume this is user error. It could definitely be, but it could also be a new bug introduced into IOS 7. It could also be an intermittent bug or a bug that just appears on certain handsets. In my experience, it's never a good idea to shrug off a bug report and tell the user it's just user error. David does a good job of explaining the technology, which may help to explain what's going on, but like I said, there's no need to just assume the user is at fault here.

Hi Christopher,

I consider myself an experienced iOS and Voiceover user and I have no issues
whatsoever on my 4S with what Rafal describes and still would like him to
provide a very specific example with detailed information step by step as to
what he is doing and what Voiceover is doing.

IMHO, I wouldn't be too quick to assume that this is just user error.
We're talking about experienced VoiceOver users after all. It is
possible that there's a bug in IOS 7 / VoiceOver.

What may also be happening to cause the jumping is that one is waiting too
long before performing a second swipe or touch of the screen, and since
the
icons on the screen are constant, if your finger has moved just a tiny
bit,
you will end up tapping on a different part of the screen. Try this...

Tap on a single icon once, then wait a couple of seconds, then tap again,
and you will notice that the icon responds as if you only tapped it once.

Now execute a double-tap by first tapping on the desired icon then quickly
tap on a different part of the screen. If you completed the double-tap
fast
enough, the app or folder will open. On the other hand, if you did it to
slowly, you will hear another icon gain the highlight.

When you touch the screen, if your finger is not already moving, VO focus
moves to the actual location on the display where your finger is touching.
Now, when your finger performs the finger flick, VO moves from its new
position on the display to the next position. This gives the appearance
that
VO is jumping around the screen, when in actual fact, you are shifting VO
before you perform the flick.

But wait, you say, I am not touching the screen before I start my flick.
This is actually something VO does not get confused about. The touchscreen
does not require any pressure whatsoever. When you hold your finger just
above the screen before starting your flick, if your finger is barely
touching the screen, so lightly that you do not feel it, this is enough
contact to activate the display and move VO focus to the actual location
where your finger is touching. Testing this in the lab demonstrates that
the
finger can barely touch the screen enough to activate it and both sighted
and blind people do not register the haptic (tactual) sensation.

An analogy is, when you are typing on a keyboard, pressing on the wrong
letter causes the wrong letter to appear in your document, no matter how
much you were thinking about pressing the correct letter. If your finger
is
heavy on the wrong letter, the key repeat activates and you get a bunch of
the wrong letter in a row in your document.

Start your flick gesture with your finger at least a quarter of an inch
above the display. This way, your finger is fully engaged in the flick
motion before it contacts the display. finally, lift your finger from the
display before you stop moving it. Exaggerate this motion until you
consistently flick without VO jumping randomly around the display.

Facebook [email protected] from my iPhone hello all,
I noticed that in iOS 7, when I swipe around on the screen, voiceover
seems to skip items. It also seems to be much more sensitive than
before.
Is there a new method that I need to know about when flicking around for
the screen? This is on an iPhone 4S. Thanks,
Mike
