iOS 7 Zoomgate
Motion sickness occurs when there's a conflict between visually perceived motion and a person's vestibular system located in the inner ear.
"For some people, that conflict can make them feel really ill," Yankee Group Research Director Carl Howe told MacNewsWorld.
"It's a real thing that affects a small percentage of the population, so it probably didn't come up in the testing of the operating system," he added.
Apple likely will address the problem by expanding the functions of the Reduce Motion button to turn off the animations.
"At the moment, there's no way to turn them off," observed Howe. "That's unusual, because Apple's been willing to turn off animations in other kinds of software."
In terms of past iOS snafus, the nausea issue is a minor one.
"It's not a major show stopper. It's not going to turn into Zoomgate," Howe said.
"The issue with the antennas and the bumper was a bigger issue," Tim Bajarin, president of Creative Strategies, told MacNewsWorld.
"For some people, though, this is a real issue, he added, and Apple is going to have to respond to it."
