How to control our iPhone with head's movements

This guide was made by iOS7 developer for the disabled people. One of the settings most important of this update was the possibility of control our smartphone with movements of our head! Let's see how to activate this setting.

First of all, go to Settings > General > Accessibility > Switch Control. Later, activate this option and, on your screen, you must see blue shapes. Now, create your first switch going on Switches > Add new switch.
Now, select your preferred source, for example Camera, and touch one of the option available for the movement of your head on the left or on the right.
Other options available for activate other option for this movement are:
- A tap
- An exchange of the apps
- A tap on the Home's button
- Opening of the Notifications Center
- Starting Siri
- The turning up or down the volume

This setting was tested by me and it works fine. This setting works only by the front camera and the head's movement. The Switches Control not works only on the iOS 7.1, but also on 7.0 update.
