Switch Control<br />
Switch Control lets you control iPhone using a single switch or multiple switches. Use any of<br />
several methods to perform actions such as selecting, tapping, dragging, typing, and even freehand<br />
drawing. The basic technique is to use a switch to select an item or location on the screen,<br />
and then use the same (or different) switch to choose an action to perform on that item or<br />
location. Three basic methods are:<br />
••<br />
Item scanning (default), which highlights different items on the screen until you select one.<br />
••<br />
Point scanning, which lets you use scanning crosshairs to pick a screen location.<br />
••<br />
Manual selection, which lets you move from item to item on demand (requires multiple switches).<br />
Whichever method you use, when you select an individual item (rather than a group), a menu<br />
appears so you can choose how to act on the selected item (tap, drag, or pinch, for example).<br />
If you use multiple switches, you can set up each switch to perform a specific action and<br />
customize your item selection method. For example, instead of automatically scanning screen<br />
items, you can set up switches to move to the next or previous item on demand.<br />
You can adjust the behavior of Switch Control in a variety of ways, to suit your specific needs<br />
and style.<br />
Add a switch and turn on Switch Control<br />
You can use any of these as a switch:<br />
••<br />
An external adaptive switch: Choose from a variety of popular USB or Bluetooth switches.<br />
••<br />
The iPhone screen: Tap the screen to trigger the switch.<br />
••<br />
The iPhone FaceTime camera: Move your head to trigger the switch. You can use the camera as<br />
two switches: one when you move your head to the left, and the other when you move your<br />
head to the right.<br />
Add a switch and choose its action. Go to Settings > General > Accessibility > Switch Control ><br />
Switches. If you use only one switch, it is your Select Item switch by default.<br />
If you’re adding an external switch, you need to connect it to iPhone before it will appear in the<br />
list of available switches. Follow the instructions that came with the switch. If it connects using<br />
Bluetooth, you need to pair it with iPhone—turn on the switch, go to Settings > Bluetooth, tap<br />
the switch, then follow the onscreen instructions. For more information, see Bluetooth devices on<br />
page 42.<br />
Turn on Switch Control. Go to Settings > General > Accessibility > Switch Control, or use the<br />
Accessibility Shortcut. See Accessibility Shortcut on page 151.<br />
Turn off Switch Control. Use any scanning method to select, then tap Settings > General ><br />
Accessibility > Switch Control. Or triple-click the Home button.<br />
