Hour 16. Using Advanced Touches and Gestures

What You’ll Learn in This Hour:

The multitouch gesture-recognition architecture How to detect taps How to detect swipes How to detect pinches How to detect rotations How to use the built-in shake gesture

A multitouch screen allows applications to use a wide variety of natural finger gestures for operations that would otherwise be hidden behind layers of menus, buttons, and text. From the very first time you use a pinch to zoom in and out on a photo, map, or web page, you realize that’s exactly the right interface for zooming. Nothing is more human than manipulating the environment with your fingers.
