The iPhone 6s and the iPhone 6s Plus have a new screen technology called 3D Touch, allowing the devices to support new gestures that are based on pressure, as well as touch. For the ﬁrst time, iPhone senses how much pressure you apply to the display. In addition to familiar Multi‑Touch gestures like Tap, Swipe, and Pinch, 3D Touch introduces Peek and Pop. This brings a new dimension of functionality to the iPhone experience.
Peek and Pop let you preview all kinds of content and even act on it — without having to actually open it. For example, with a light press you can Peek at each email in your inbox. Then when you want to open one, press a little deeper to Pop into it.
With Quick Actions, 3D Touch provides shortcuts to the things you do most, so you can send a message or take a selfie with just a simple press from the Home screen. For example, you just press the Phone icon to quickly call one of your favorite contacts.
A Whole New Dimension Of Technology
Using 3D Touch is simple. But the engineering behind it is incredibly advanced. When you press the display, capacitive sensors instantly measure microscopic changes in the distance between the cover glass and the backlight. iOS uses these measurements to provide fast, accurate, and continuous response to ﬁnger pressure, which could only happen with deep integration between software and hardware. iPhone 6s also provides you with responsive feedback in the form of subtle taps, letting you know that it’s sensing the pressure you’re applying.
