Will be doing a presentation on accessibility solutions in April and had
similar issues. What I'm playing with and going to try is using a device
called an ELMO. It's sort of a camera on stick with a base that outputs
VGA video of whatever is underneath it. I'll probably do demos on an
iPad instead of the iPhone as the image will be larger and the
functionality is more or less the same. My workplace provided the ELMO
but I suspect most AV rental places would carry something similar.
Before that I had used an old iSight camera taped to a pile of about 5
reams of paper so it was pointing down. Then I could put an iPhone up
against the paper pile so the top was in view and taped down a pencil to
the table to know where the left edge needed to be. This took a lot of
prep time and the images were not very clear since the iSight is only
640x480 resolution. iPhone screen alone is 960x640 resolution so there
were other weird moire patters and such. The ELMO is 1280x960 so it is
much clearer. I'm using the TT-02RX model. I've heard that the iPad2 has
VGA video out but I don't have one of those to test. From what I could
find it sounded like it wasn't true video mirroring and rather the apps
could send some video output to the external display if they were coded
to do so. I also wanted people to be able to see what I was doing with
my hands so the overhead camera seems like a better way.
A funny aside. I went to an accessible devices presentation a while back
where the person was demoing an iPhone. He got to some point where he
needed to enter a password and for a moment took the device and turned
around so we couldn't 'see' what he was putting in. Only a few
characters later did he realize we could all hear what he was typing
just fine :)
Hope this helps.

Dear listers,
In two months, I will be visiting my family in the U.S. While there, I will be
doing a demonstration of access technology for blind people. While it won't be
difficult to demo screen reader techniques on a Mac, I am still not sure how to
demo VO on an iPhone. Most of the people in my audience will be sighted, and
they will want to see what is going on on the screen while I work with the
unit. Does anyone have any ideas on how I might be able to project the image
of the iPhone screen onto a large wall screen so that people could see what was
happening on the phone as I used it?
Many thanks,
Mike
