The iPhone X is about to be released, and in one way or another, officially sanctioned or not, a handful of videos have appeared showing different functions of the device. The following is a short video showing the new way users will change application on the iPhone X.
As the iPhone X does not have a home button, Apple engineers have had to rework several control schemes, including switching between applications. On an iPhone with a home button, users would double-tap the button, which would move iOS to a map-like view of running apps. Users could then slide between them. But on the iPhone X, the user interaction is a little more native.
The video above shows that to change the application on the iPhone X, users must create an arch while scanning the home screen. The running application is thus set aside and the previous application running takes its place. This is an applications carousel.
This is not the only way to switch from one application to the other. If a user swipes up on the home screen, he pulls a screen similar to the one found on iPhones equipped with the Home button (and the Palm Pre).
