When Apple releases iOS 7, the “Accessibility” feature will allow you to control your iPhone or iPad using left and right head movements. The feature was discovered by a source with 9to5Mac. You have to move your head around when it is bordering around the option that you want. For example, moving your head to the left or right can activate the home button, Siri, Notification Center, or open the App Switcher. It can also be used to decrease/increase volume or simply act as a tap. Check out the video demo above.
