A user experience expert has put together a video showing that the longer animations introduced in iOS 7 and continued in iOS 8 have a small usability cost: user input is ignored while the animation is running, making the user interface seem slower. The video compares it to iOS 3 running on the original iPhone.
While William Van Hecke believed that the issue was that animations used to be interruptible, this isn’t actually the case except for Springboard. In other cases, iOS has always ignored input until animations are complete, it’s just that they used to be shorter. If you’re fast with your fingers, there will now be times when you’re trying to do something while the animation is still doing its thing.
The new spring-based animations also make it less clear when the animation has ended, so the device seems unresponsive to input, but in reality it’s that the animation hasn’t quite finished.
Do you see this as an issue in real-life use? Let us know in the comments.
