Learn how to use switch control on your iPad Air. Switch control lets you control iPad using a single switch, or multiple switches. Use any of several methods to perform actions such as selecting, tapping, dragging, typing, and even free-hand drawing. The basic technique is to use a switch to select an item or location on the screen, and then use the same (or different) switch to choose an action to perform on that item or location. Three basic methods are:
Item scanning (default), which highlights different items on the screen until you select one.
Point scanning, which lets you use scanning crosshairs to pick a screen location.
Manual selection, which lets you move from item to item on demand (requires multiple switches).
Whichever method you use, when you select an individual item (rather than a group), a menu appears so you can choose how to act on the selected item (tap, drag, or pinch, for example).
An external adaptive switch. Choose from a variety of popular USB or Bluetooth switches.
The iPad screen. Tap on the screen to trigger the switch.
The iPad FaceTime camera. Move your head to trigger the switch. You can use the camera as two switches; one when you move your head to the left, and the other when you move your head to the right.
