Nintendo Patent Shows Freeform Display For (NX?) Controller/Portable

[Pavolink]

What I get from this:

Controller has 2 sticks and shoulder buttons.

The screen can display different number of buttons, all of them according to the game. For example, for a Zelda game the controller can display 3 buttons for items, one for actions (A) and one for the sword (B).

For a 2D Mario Game maybe it will only display 3 buttons: one to run, one to jump and one to use powerups.

For some kind of Metroid Prime game for example it can display the different beams.

 

For the buttons, not only haptic feedback can work, but also tactus:

 

I expect the console component to have a normal controller and this to be optional.

All in all, I like the concept and I'm willing to try.

 

Edit: I wouldn't be surprised if they were even trying digital sticks, but maybe those are to early to be functional enough, thus they only focused on face buttons.
