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 app features. 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
Disable the iPod touch hardware buttons
Turn on Guided Access. Go to Settings > General > Accessibility > Guided Access, where you can:
Turn Guided Access on or off
Set a passcode that controls the use of Guided Access and prevents someone from leaving a session
Set whether other accessibility shortcuts are available during a session
Start a Guided Access session. Open the app you want to run, then triple-click the Home button. Adjust settings for the session, then click Start.
Disable app controls and areas of the app screen: Circle any part of the screen you want to disable. Use the handles to adjust the area.
Enable the Sleep/Wake or Volume buttons: Tap Options and turn on the buttons.
Ignore all screen touches: Turn off Touch.
Keep iPod touch from switching from portrait to landscape or from responding to any other motions: Turn off Motion.
End a Guided Access session. Triple-click the Home button, enter the Guided Access passcode, and tap End.
