The fact that tablets are increasingly tools for running games of greater complexity makes this type of patent not strange. Nexus 7 now influenced some concepts that made the design of the device somewhat similar to portable consoles in certain respects. Now we receive news of a patent that would give rise to the placement of a series of buttons on the back of the iPad with the aim of improving its functions when it comes to enjoying video games, facilitating handling of these.
This patent is original in a sense, since it is not only reduced to putting buttons on the back of the iPad, but also has devised a system to show on screen which means to press the button at every moment. Such a feature supposes a visual guide of finger placement, something that would simplify controls that might otherwise be messy.
The details of this patent also specify that the control of the buttons would be "configurable”, Giving developers the freedom to adapt them to the specific characteristics of their games. It also refers to a type of professional haptic / psychic as feedback for the user on the controls. When we perform an action, there would be some kind of vibration or slight and immediate force that would indicate that the order has been executed before we can even see the results on the screen.
