We're used to pinching, swiping and tapping our phones, but now how hard you press the screen makes your phone do more.
Apple calls it 3D Touch on the iPhone 6s and 6s Plus.
Think of it like right clicking a mouse to bring up extra options.
This is how it works.
When you press the screen, capacitor sensors behind the display read changes in distance between the cover glass and the back light.
So a 3D touch can tell the difference in pressure from a top to a deep press.
The phone also makes tiny vibrations from the taptic engine so you can feel what you're doing.
A light press on the screen will open a preview of content like a map, an email, or a message.
This is called a peek.
Release your finger, and you go back to where you were.
But if you keep pressing your finger harder, it opens the content.
That scrolls a pop.
3D touch also works on the home screen with something called click actions.
Press an app icon to bring up shortcuts ike launching the front facing camera or calling a favorite contact.
That's your right click analogy.
Overall it's designed to reduce the number of taps you need to make on the screen.
3D touch is also going to work in multitasking, drawing, and could open up a whole new way of interacting with games.
It sounds complicated but soon pushing a screen will be second nature.
