Max Rudberg of Max Themes has tried to imagine a smaller iPhone with, as according to recent speculation, an "edge-to-edge" screen. While the WSJ report doesn't give many details about the nature of such a screen (is it "edge-to-edge" vertically, or horizontally?), it admittedly plays very well with previous rumors of future iPhones lacking a home button. So what Max did, and you can check out in the video below, is think about a phone that's really just a screen, but that you can "squeeze" to close apps and go back to the Springboard.
A more intuitive way could be to equip the phone with a pressure-sensitive body. The phone could then be squeezed and the current app would shrink and return the user to the Home screen.
This could be a real wow effect. Seeing how the phone reacts to your grip and then having the app vanish in the palm of your hand.
To avoid 'squeeze to go Home' from happening by accident, a visual cue could show that pressure is being applied. In this concept, the app begins to shrink to reflect the pressure that is being applied. When the pressure goes over a defined threshold, the user is returned to the Home screen.
It sounds very futuristic, we know, but it could be a good idea for when the iPhone will eventually lose the Home button. What do you think?
