Re: Parallax and vestibular disorders

I think it's worth exploring... We would want to get out of the theoretical
possibility of it being a problem into real world problems that actual
users are having ... the article dates back to iOs 7 and a cursory reading
of it seemed that the author was saying dizziness is a possibility but
again was a theoretical possibility, not an outcry from users.

I've heard it is a problem for some users, but have never met a user who's
really had serious problems from it... but the next step would be to talk
to some users, preferably a user group representing them, to gather more
data on the real world problems they have.

For our photo epileptic SC in about 2003, we had a presentation at the Los
Angeles face to face by an organization in England that came to us with the
proposal. I would hope for something similar here so we are talking to
people who are really serious about the issue.

Does anyone know of such a user group or place to talk to users?

Cheers,
David MacDonald
