The iPad's Multi-Touch Screen
The iPad's home screen (see the following figure) displays a pretty background and two sets of icons. One set appears along the bottom of the screen. This is called the Dock, and it contains icons for Safari, Mail, Photos, and Music apps by default, though you can add two other apps to it if you wish. The Dock appears on every Home screen. The other set of icons appears above the Dock. Here, different icons appear on each Home screen. You can populate up to 12 Home screens with apps, and move apps from one Home screen to another.
Treat the iPad screen carefully. It's made of glass and will smudge when you touch it (and will break if you throw it at the wall).
The iPad uses touchscreen technology. When you swipe your finger across the screen or tap it, you're providing input to the device just as you use a mouse or keyboard with your computer. You hear more about the touchscreen in the next task, but for now, go ahead and play with it for a few minutes; really, you can't hurt anything. Use the pads of your fingertips (not your fingernails), and follow these steps:
Tap the Settings icon. The various settings appear, as shown in the following figure.
To return to the Home screen, press the Home button.
Swipe a finger or two from right to left on the screen. If downloaded apps fill additional Home screens, this action moves you to the next Home screen. Note that the little dots at the bottom of the screen, above the Dock icons, indicate which Home screen is displayed.
To experience the screen rotation feature, hold the iPad firmly while turning it sideways. The screen flips to horizontal orientation. To flip the screen back, just turn the device so it's oriented like a pad of paper again.
Drag your finger down from the top of the screen to reveal Notification Center; drag up from the bottom of the Home screen to display Control Central.
You can customize the Home screen by changing its wallpaper (background picture) and brightness.
