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.

Further to accessibility discussions on Wikipedia


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?
