Guided Access
Guided Access helps an iPod touch user stay focused on a task. Guided Access dedicates
iPod touch to a single app, and lets you control which app features are available. Use Guided
Access to:
•
Temporarily restrict iPod touch to a particular app
•
Disable areas of the screen that aren’t relevant to a task, or areas where an accidental gesture
might cause a distraction
•
Limit how long someone can use an app
•
Disable the iPod touch hardware buttons
Use Guided Access. Go to Settings > General > Accessibility > Guided Access, where you can:
•
Turn Guided Access on or o
•
Set a passcode that controls the use of Guided Access and prevents someone from leaving a
session
•
Tap Time Limits to set a sound or have the remaining Guided Access time spoken before
time ends
•
Set whether other accessibility shortcuts are available during a session
Start a Guided Access session. After turning on Guided Access, open the app, then triple-click
the Home button. Adjust settings for the session, then tap Start.
•
Disable app controls and areas of the app screen: Draw a circle or rectangle around any part
of the screen you want to disable. Drag the mask into position or use the handles to adjust
its size.
•
Enable the Sleep/Wake or volume buttons: Tap Options below Hardware Buttons.
•
Keep iPod touch from switching from portrait to landscape or from responding to other
motions: Tap Options, then turn o Motion.

Set a session time limit: Tap Time Limit Options at the bottom of the screen.
End the session. Triple-click the Home button, then enter the Guided Access passcode.
Switch Control
Switch Control lets you control iPod touch 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 dierent) switch to choose an action to perform on that item
or location. Three basic methods are:
•
Item scanning (default), which highlights dierent 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).
