Aside from the usual complaints, many folks who have downloaded the new operating system are complaining of motion sickness. Yes, really. Honest to goodness motion sickness, complete with headaches and nausea.
There are two things responsible for this… the zoom and parallax features. (Parralax explained: Parallax and the iOS 7 Wallpaper)
All of the moving and zooming and sliding is making people nauseous. Some comments from around the web:
“The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache.”
“I had severe vertigo the minute I started using my ipad [sic] with ios 7.”
You can reduce some motion by going to “Settings” > “General” > “Accessibility.” Find “Reduce Motion” and turn it on. Unfortunately, this doesn’t fix the problem, it just helps a little bit.
