The controllers are authenticated on modern consoles and have been for a long time. So by interface you'd have to mean like, a robotic hand.

And if that ever becomes a real problem they add a 3D camera to the controller or require it to be positioned below the screen, and use ML to decide if there's a human in front of the machine or not. AI cuts both ways. Integrated hardware devices aren't necessarily easy to just cut into. That's why it's hard to mod consoles to begin with.
