[See this article](https://source.opennews.org/articles/motion-sick/) for further details and illustrations. + +**At the very minimum, allow the user to disable animations which may create effects

support the prefers-reduced-motion media query](https://webkit.org/blog/7551/responsive-design-for-motion/) to design accordingly. + +There’s little we can do about interactive EPUB contents themselves, but we can at least promote what Mozilla got wonderfully right from the start to authors, i.e. [an overlay asking users to set their preference](http://devtoolschallenger.com). + ##

    Vestibular disorders

    + +

    There’s an a11y “issue” which is quite unknown, but may impact a lot of people, either temporarily or permanently: vestibular disorders.

    + +

    To put it simply, some interactions can make the user dizzy, uneasy, and in some cases ruin her/his entire day, because the user feels like they can’t keep balance when walking or even staying up, or feel vertigo. See this article for further details and illustrations.

    + +

    At the very minimum, allow the user to disable animations which may create effects (e.g. page-transition animation). But everything else will vary from implementation to implementation.

    + +

    On iOS/Mac, there’s a system setting which has been implemented and browsers increasingly support the prefers-reduced-motion media query to design accordingly.

    + +

    There’s little we can do about interactive EPUB contents themselves, but we can at least promote what Mozilla got wonderfully right from the start to authors, i.e. an overlay asking users to set their preference.
