Apple has already made a number of changes to their home button on the iPhone and iPad over the last few years, the home buttons in the latest devices comes with a fingerprint scanner.
Now it would appear that Apple has plans to use the home button for gaming in the future, as a new patent filing has been discovered.
This new home button can be seen in the pictures below, the button has two modes, standard which will work like the current home button, and a gaming mode, where the button transforms into a gaming joystick.
As you can see in the next photo, when the home button is popped up, it can be used in a similar way to a joystick for gaming.
It certainly looks very interesting from the pictures, and this new patent fling was published by the USPTO yesterday.
Of course Apple may never use this new transforming home button in the future devices, lets hope they do as it could improve gaming controls on the iPhone and iPad. Have a look at our handy guide on how to improve your iPhone battery life.
