Touch 3D or Force Touch, is a technology introduced by Apple in September 2014 on iPhone devices, with the launch of the iPhone 6s model.
What is 3D Touch (Force Touch) and how does it work?
3D Touch (Force Touch) is offered to the user Quick access to a set of options directly from the application iconby pushing forcefully into the screen.
The screen capability to detect fingerprint pressure on screen is given by a set of sensors very sensitive integrated in displaythe devices Apple carand I use Force Touch. They can determine the pressure placed on the surface of the screen by measuring microscopic distances between the light behind the screen (back light) and its surface. In this way, the force with which the screen is pressed is established. At the moment of identifying a firm press, the device will vibrate for 10 milliseconds, providing a sensitive "response" to the user.
This force touch detection function (Force Touch) has provided support to several functions directly from the touch screen. home of the iPhone, without the need for the user to open the application first. Twitter, Instagram, WhatsApp, Email, Calendar, Phone Number there are only a few of the iPhone applications that support 3D Touch.
The 3D Touch feature has been added by Apple and for trackpad- the newer MacBook generations. They are able to "feel" the force with which they are pressed and perform specific functions. In addition, thanks to some tiny servo motors, feedback vibrations are felt by the user exactly where he presses trackpad.
3D Touch is available on iPhone 6s, iPhone 7, iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS and iPhone XS Max. For iPhone Xr, Apple preferred Haptic Touch instead of 3D Touch.
What is Haptic Touch and how does it work?
Haptic Touch is a feature almost similar to 3D Touch, but it does not detect the force of pressing on the screen, but only the duration. So that the function is activated after a long press and not after a firm press.
The feature has been added by Apple on the iPhone XR as a substitute for 3D Touch. Function that could not be included on this new iPhone model. However, Haptic Touch is only available for the flashlight, the Camera app on the main screen and for some basic iPhone options. Haptic Touch does not support Twitter, Instagram or other applications.
It is expected in the future Apple to provide greater Haptic Touch coverage on future iPhone models and iOS versions.
