♪ Music playing ♪With iPhone and Multi-Touch,we introduced a whole new way to interact with technology. Tapping, swiping, and pinching have forever changedthe way we navigate and experience our digital world. Until now, these gestures have been definedby a singular plane in two-dimensional space. For iPhone 6s and 6s Plus,we're introducing an entirely new interactionand a whole new dimensionto the way you experience your iPhone. ♪It's made possible by a technology called 3D Touch. This is the next generation of Multi-Touch. For the first time, along with recognizing familiar gestures,iPhone also recognizes force,enabling new gestures -- Peek and Pop. ♪3D Touch works on the Home screen,giving you shortcuts to the things you do frequently. It also works inside applications themselves. Press lightly, and it gives you a peek at the content. Continue pressing,and it pops you into the content itself. Sensors embedded in the display read how hard you're pressingand react in a smooth, linear way. This is a dynamic system deeply integrated into iOS 9. ♪You can dip in and out of where you arewithout losing a sense of your context. It provides distinct, tactile feedbackfor your actions,letting you know exactly what you've done,and what to expect. While the way that you use 3D Touch is simple,the engineering behind it is some of our most advanced. At its heart are capacitive sensorsintegrated into the backlight of the Retina HD display. With each press,these sensors measure microscopic changesin the distance betweenthe cover glass and the backlight. These measurements are then combinedwith signals from the touch sensorand accelerometerto provide fast, accurate,and continuous response to finger pressure. For a truly communicative experience,we had to develop a more precise levelof haptic feedback. While the vibrating system on a typical phonerequires 10 or more oscillations to reach full power,the Taptic Engine in iPhone 6sreaches peak output in just one cycle,and stops just as quickly. This allows us to create shorter,more distinct feedback events,like a mini tap lasting just 10 milliseconds,and a full tap which lasts 15 milliseconds. Perhaps more than any other system we've designed,3D Touch is a clear exampleof how hardware and software developed togethercan work to define a singular experience. This is the next generation of Multi-Touch. It makes this iPhonethe most advanced iPhone we have ever created. ♪
