Subject: Guidelines for Animation/Motion Sickness?
No previous message | Next message →

The use of animation on Web sites is something I am seeing more of in sites we review and I had a question about updated animation guidelines in relation to vestibular disorders such as motion sickness, vertigo or headaches. Some interesting sites that I could see being problematic (at least to me) include:

http://www.digitalhands.net
http://hellomonday.com
https://www.adamunderwear.com

And also iPhone 7 - http://www.webaxe.org/vestibular-issues-parallax-design/

I know WCAG 2.0 restricts videos/animations to 5 seconds (unless a pause button is provided), but even so it seems like some 5 seconds can be too long for some animation effects. I did find some recommendations/discussions at these sites

http://www.webaxe.org/vestibular-issues-parallax-design/

So...have people encountered this kind of issue on websites they review, and if so, what guidelines do people recommend? I don't think it's quite covered in WCAG, but yet is an issue to address.

Hope this makes sense.

Thanks
Elizabeth

P.S. Actually, I can handle the iPhone, but I will confess that some parallax animations can give me a headache.

There is nothing in WCAG 2.0that directly addresses this.
It could be put as a best practice/usability issue under 2.2.2 I tink.
But efforts are underway to address this in future:

WCAG 2.1 proposed success criterion to cover animations (extend 2.2.2)
