alt Hacker News>the gesture is no longer “press” but “swipe” and the UI element is not a button but edge of the screen itself.
Right, but while it's obvious to everyone that a button is a control, it's not obvious that an edge is a control. On top of that, swiping up from the bottom edge triggers two completely different actions depending on exactly when/where you lift your finger off the screen.
Why not move the physical home button to the back of the phone?
I think a button that is located behind the screen fits the definition of “hidden interface control” more so than a swipeable screen edge.
Forwhat it’s worth, back tap is a feature of iOS to which you can assign an action, though it only triggers on double or triple tap.
