Since the release of iOS 7, there have been numerous users and reports of motion sickness due to the parallax and zooming effects within the firmware. For those unfamiliar with the parallax effect, it's used on the Lockscreen/Homescreen wallpaper, while tilting an iOS device, the wallpaper will tilt with it. While the zooming effect is when a user opens or closes a folder in iOS 7. Most won't find this a big issue, but some folks prone to motion sickness needed a solution.
Before iOS 7.0.3, the only option was to turn on the parallax effect, leaving the folder zooming still on. This was done by going to Settings > General > Accessibility > Reduce Motion. Now in iOS 7.0.3, there is a new option which will turn off both zooming and parallax. Instead of zooming in and out, the folders will nicely fade in and out of the Homescreen. Hopefully in the next firmware update, Apple will give the option to turn these features off individually for those who have a problem with one and not the other.
