AssistiveTouch helps you use iPhone if you have difficulty touching the screen or pressing the buttons. You can use AssistiveTouch without any accessory to perform gestures that are difficult for you. You can also use a compatible adaptive accessory (such as a joystick) together with AssistiveTouch to control iPhone. To configure the AssistiveTouch menu, go to Settings > General > Accessibility > AssistiveTouch.
AssistiveTouch lets you perform the following actions and more just by tapping (or the equivalent on your accessory):
Turn on AssistiveTouch. Tell Siri “turn on AssistiveTouch,” go to Settings > General > Accessibility > AssistiveTouch, or use Accessibility Shortcut. When AssistiveTouch is on, the floating menu button appears on the screen.
Add more actions to the AssistiveTouch menu. Go to Settings > General > Accessibility > AssistiveTouch > Customize Top Level Menu. The menu can have up to eight actions.
Show or hide the AssistiveTouch menu. Tap the floating menu button, or click the secondary button on your accessory.
Show the Home screen. Tap the menu button, then tap Home.

Siri is often the easiest way to start using accessibility features with iPhone. With Siri, you can open apps, turn many settings on or off (for example, VoiceOver), or use Siri for what it does best—acting as your intelligent personal assistant.
