Adjust how iPod touch responds to your touch
If you have difficulties with hand tremors, dexterity, or fine motor control, you can adjust how the iPod touch touchscreen responds to tap, swipe, and touch-and-hold gestures. You can have iPod touch recognize faster or slower touches and ignore multiple touches. You can also prevent iPod touch from waking when you touch the screen, or turn off Shake to Undo if you unintentionally shake iPod touch.
Adjust settings for taps, swipes, and multiple touches
Go to Settings
> Accessibility > Touch > Touch Accommodations, then turn on Touch Accommodations.You can configure iPod touch to do any of the following:
Respond to touches of a certain duration: Turn on Hold Duration, then tap
or 
to adjust the duration. (The default is 0.10 seconds.)Prevent unintended swipe gestures: To increase the amount of movement required before a swipe gesture begins, tap Swipe Gestures, turn on Swipe Gestures, then adjust required movement.
Treat multiple touches as a single touch: Turn on Ignore Repeat, then tap
or to adjust the amount of time allowed between multiple touches.Respond to the first or last place you touch: Choose Use Initial Touch Location or Use Final Touch Location.
If you choose Use Initial Touch Location, iPod touch uses the location of your first tap—when you tap an app on the Home Screen, for example. If you choose Use Final Touch Location, iPod touch registers the tap where you lift your finger. iPod touch responds to a tap when you lift your finger within a certain period of time. Tap
or to adjust the timing. Your device can respond to other gestures, such as a drag gesture, if you wait longer than the gesture delay.
Adjust settings for touch-and-hold gestures
The touch-and-hold gesture reveals content previews, actions, and contextual menus. If you have trouble performing this gesture, do the following:
Go to Settings
> Accessibility > Touch > Haptic Touch.Choose the touch duration—Fast or Slow.
Test the new setting on the image at the bottom of the screen.
Turn off Shake to Undo
If you tend to unintentionally shake iPod touch, you can turn off Shake to Undo. Go to Settings > Accessibility > Touch.
