The new iPhone 7 has no physical Home button, but a completely virtual, that works with the Taptic Engine in order to give the same feeling of real “clicks”. Thanks to the API issued by Apple, developers can also program the behavior of the Home button in games and applications.
The Home key can be set with three different levels of tactile feedback, from less sensitive to a truly very powerful, similar to a pressure of a physical key. With the new API Taptic Engine, developers can exploit this tactile feedback, on the device screen, through 3D Touch that’s with the new iPhone 7 Home button. It is simply a new opportunity for development, in the latest iOS 10 beta,but that should be available for the final version of the operating system. We just have to wait to see how developers will be able to integrate these functions to create new types of interaction with our devices . The first use case scenario that comes to mind is a “shooter type game” where one can just shoot resting a finger lightly on the Home button, leaving the entire screen free for the clearer view of the game, no obstructive virtual button(s) in the corner.
