It’s no secret that a lot of people consider scrolljacking and parallax effects annoying and overused. But what if motion does more than just annoy you? What if it also makes you ill? That’s a reality that people with visually-triggered vestibular disorders have to deal with.
As animated interfaces increasingly become the norm, more people have begun to notice that large-scale motion on screen can cause them dizziness, nausea, headaches, or worse. For some, the symptoms can last long after the animation is over. Yikes.
The idea that animation in our interfaces is capable of making our users dizzy wasn’t something we had to contend with much when the web was predominantly a static medium. It’s actually a fairly new revelation in most tech circles. …
Just like other elements of design, the way you use animation can have an impact on how accessible the end product is to your audience, especially if they suffer from a vestibular disorder.
A vesti-what disorder?
Any disease, damage, or injury to the vestibular system—the system around our inner ear and brain that processes sensory information involved in controlling balance and eye movements—falls under the umbrella of a vestibular disorder.
According to vestibular.org, approximately 8 million American adults report a chronic problem with balance, while an additional 2.4 million report a chronic problem with dizziness.
