RE: Wanted: evidence of negative effects of moving images

No formal test, but many of my students (not only the dyslexic ones) have problems with http://www.richard3museum.co.uk/main.html - especially when it gets onto the second screen with text below - very few people's reading speed can keep up with some of the captions.

I use it as an example of how not to do it.

Hi

I don't know of any large studies, other than perhaps the DRC's formal
investigation into website accessibility, which might have a section on
this subject.  However, I recently user tested a website with moving Flash
images.  The Flash contained text.  My dyslexic participants couldn't
actually read the text in the time permitted and also found the changing
image distracting when viewing other sections of the page.

I'm looking for evidence of people with disabilities who are
caused problems by moving images. I know about rapid flashing a photo-
sensitive epilepsy, but I'm looking for citations that people with
cognitive disabilities, head injuries, dyslexia or whatever can be
effected by moving (as opposed to rapidly flashing) images,.

Can anyone help, please?
