3D Touch is a technology that apple has implemented into it’s currently generation of iPhone to add a new dimension to the user interface. It now means there are three levels of force that can be applied to the screen that will offer the user a different experience, these are a tap, gentle press and hard press. A great video explaining it is below.
There is also technology researched by Disney to complement the 3D touch that would give tactile feedback to the user based on what was on the screen. This means the device could imitate the feel of an object and bumps and can also add resistance to the screen.
Haptic Feedback is something Apple have alreadly implemented into the iPhone to allow the user to understand when they have pressed harder for the 3D touches. This is just the beggining, using 3D touch more thoroughly throughout the operating system and creating different ways of doing things using these techniques will change the way people interact with their phones forever.
