Appendix A Accessibility 145
If you use multiple switches, you can set up each switch to perform a specic action and
customize your item selection method. For example, instead of automatically scanning screen
items, you can set up switches to move to the next or previous item on demand.
You can adjust the behavior of Switch Control in a variety of ways, to suit your specic needs
and style.
Add a switch and turn on Switch Control
You can use any of these as a switch:
•
An external adaptive switch: Choose from a variety of popular USB or Bluetooth switches.
•
The iPod touch screen: Tap the screen to trigger the switch.
•
The iPod touch 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.
Add a switch and choose its action. Go to Settings > General > Accessibility > Switch Control >
Switches. If you use only one switch, it is your Select Item switch by default.
If you’re adding an external switch, you need to connect it to iPod touch before it will appear
in the list of available switches. Follow the instructions that came with the switch. If it connects
using Bluetooth, you need to pair it with iPod touch—turn on the switch, go to Settings >
Bluetooth, tap the switch, then follow the onscreen instructions. For more information, see
Bluetooth devices on page 36.
Turn on Switch Control. Go to Settings > General > Accessibility > Switch Control, or use the
Accessibility Shortcut. See Accessibility Shortcut on page 128 .
Turn o Switch Control. Use any scanning method to select, then tap Settings > General >
Accessibility > Switch Control. Or triple-click the Home button.
Basic techniques
Whether you use item scanning or point scanning, the Switch Control basics are the same.
Select an item. While the item is highlighted, trigger the switch you’ve set up as your Select Item
switch. If you are using a single switch, it is your Select Item switch by default.
Perform an action on the selected item. Choose a command from the control menu that appears
when you select the item. The layout of the menu depends on whether you use Auto Tap.
•
With Auto Tap o: The control menu includes only the Tap button and the More button (two
dots at the bottom). If you’re in a scrollable area of the screen, a Scroll button also appears.
To tap the highlighted item, trigger your Select Item button when Tap is highlighted. To see
additional action buttons, choose More at the bottom of the menu. If you have multiple
switches, you can set one up specically for tapping.
•
With Auto Tap on: To tap the item, do nothing—the item is automatically tapped when the
Auto Tap interval expires (0.75 seconds if you haven’t changed it). To see the control menu,
trigger your Select Item button before the Auto Tap interval expires. The control menu skips
the Tap button and goes right to the full set of action buttons.
Turn on Auto Tap. Go to Settings > General > Accessibility > Switch Control > Auto Tap. To tap an
item with Auto Tap on, just wait for the Auto Tap interval to expire.
Dismiss the control menu without choosing an action. Tap while the original item is
highlighted and all the icons in the control menu are dimmed. Or choose Escape from the
control menu. The menu goes away after cycling the number of times you specify at Settings >
General > Accessibility > Switch Control > Loops.
