AssistiveTouch

AssistiveTouch helps you use iPod touch if you have difficulty touching the screen or pressing the buttons.

You can also use AssistiveTouch without an accessory, to perform gestures that are difficult for you.

Turn on AssistiveTouch. Go to Settings > General > Accessibility > AssistiveTouch, or use the Accessibility Shortcut. See Accessibility Shortcut on page 107.

Adjust the tracking speed (with an accessory attached). Go to Settings > General > Accessibility > AssistiveTouch > Touch speed.

Show or hide the AssistiveTouch menu (with an accessory attached). Click the secondary button on your accessory.

Move the menu button. Drag it to any location on the screen.

Perform a swipe or drag that uses 2, 3, 4, or 5 fingers. Tap the menu button, tap Device > More > Gestures, and then tap the number of digits needed for the gesture. When the corresponding circles appear on the screen, swipe or drag in the direction required by the gesture. When you finish, tap the menu button.

Perform a pinch gesture. Tap the menu button, tap Favorites, and then tap Pinch. When the pinch circles appear, touch anywhere on the screen to move the pinch circles, then drag the pinch circles in or out to perform a pinch gesture. When you finish, tap the menu button.
