Apple's iPhone and iPad owners have been taking to the company's forums over the past week to complain about iOS 7's new parallax and zoom features. Many of the folks in the forum said that they've experienced motion sickness, vertigo, nausea, and headaches due to the motion on-screen.
"The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache," one forum poster wrote last week. "It's exactly how I used to get car sick if I tried to read in the car."
Several posters reported similar issues over the past week, and some said that they've tried calling Apple about the problem, but were told that only some of the features can be turned off. Some users report resorting to downgrading from iOS 7 to iOS 6.
iOS 7's design was built completely from the ground up. The operating system's color scheme is simpler and a new parallax feature allows users to feel as though they're head on with the display even as it's being tilted in different directions. The new operating system, which was conceived by the company's design guru Jonathan Ive, also has new zoom functions to access applications.
Although zoom functions will likely remain in place with no ability to modify them, the parallax option can be mitigated from the Accessibility menu in iOS 7. Upon choosing "reduce motion," users should be able to turn off the parallax function.
CNET has contacted Apple for comment on the forum complaints. We will update this story when we have more information.
