Use Switch Control on iPhone
With Switch Control, there are two methods to select an item on the screen:
Item scanning: The focus moves (automatically or manually) from one item to the next until you select an item; this is the default scanning method.
Point scanning: You select an item on the screen by pinpointing it with scanning crosshairs.
After you select an item, you can choose an action (for example, tap, drag, or pinch) in the Scanner Menu.
Use item scanning
With item scanning, the focus sequentially moves from one item to the next item on the screen.
If you use Auto Scanning, watch or listen as the focus moves. If you use Manual Scanning, trigger your Move to Next Item switch to move the focus.
When the focus surrounds the item you want, trigger your Select Item switch.
In the Scanner Menu, choose an action such as the following:
More (the dots at the bottom of the menu) for more options
Home (to return to the Home screen)
Device (for other hardware actions)
Settings (to adjust Switch Control behavior)
The available actions in the Scanner Menu depend on the selected item.
To dismiss the Scanner menu without choosing an action, trigger your switch while the original item is highlighted and all the icons in the Scanner Menu are dimmed.
Switch from item scanning to point scanning
Point scanning lets you select an item on the screen by pinpointing it with scanning crosshairs.
Use item scanning to select an item.
In the Scanner Menu, choose Point Mode.
To position the vertical crosshair, do the following:
Trigger your Select Item switch when the wide vertical band is over the item you want.
Trigger your Select Item switch again when the fine vertical line is over the item.
Repeat to position the horizontal crosshair.
Choose an action from the Scanner Menu.
To return to item scanning, choose Item Mode from the Scanner Menu.
