Apple Patent : A home button that turns into a joystick

Apple has won a patent from (USPTO) for the home button of the iPhone and the iPad. Deposited in July 2013, it describes the same round button to that which can be found on brand appliances. It is however equipped with a mechanical attribute possible to transform it in mini joystick.
