But when the user summons the home button the display it will become 3:2 ratio display. And of course, you don't have to make an additional area for home button because the home button appears at the screen. So basically, the iphone (with virtual home button) 's front panel will only contain receiver and facetime camera. And the most great part is that although the new iphone will have 16:9 ratio display, it will be not so long because the front panel will have only screen and no home button area. This will make the grip more comfortable. 3) The most important part : The UI and features of virtual home 1. How to summon virtual home button : First, place two fingers at the very bottom of the display. Second, place those fingers at right and left side of the display. Then finally, pinch the two finger.

The home button of 16:9 screen. : This time the home button area won't appear at the display. Instead, the home button will become a half-invisible, thumb sized toggle key. 4. The possible UI change of multitasking bar, Siri tab, iAD, and Push notification I. multitasking bar : If you double click the virtual home button, the home button area will become a multitasking bar.

This also means that you can use both Siri and other apps at the same time. This can make users to write notes and search Wolfram Alpha on a same time, or write text message and correct typo at a same time.(By talking Siri, Correct all typo while writing text message with another hand) Also developers can make Siri controlled apps (especially games) as Siri can be used while the apps are running. III. Notification push and iAD will appear on the home button area. This will not interrupt user. 5) Other great features you can add to virtual home button area 1. Shortcut : This is a small button that will be on the right side of the virtual home button. When you click it, you can select various apps then turn on instantly.
