What is it with Apple and the gaming-related patents as of late?
Just weeks after the publishing of an Apple patent showing a concealed gaming joystick capable of being hidden in future iPhones, today the U.S. Patent and Trademarks Office has revealed another Apple invention related to a snap-on gaming controller for iOS devices.
As with the joystick patent, the idea here is to allow gamers to fully capitalize on the present golden age of iOS gaming, without having to block parts of the screen using their fingers for multitouch controls.
