The PlayStation 4's controller, the DualShock 4, was developed with the insight of a number of major shooter developers according to system architect Mark Cerny.
Speaking to IGN he said:
"We made and tested a ridiculously broad style of controllers and we would actually have people play games with them. And the current controller design came out of that. We did indeed conclude that the two joysticks on the same level works perfectly well. That did come out of our testing."
He went on to add that "We sent out prototypes to major FPS creators."
"We looked at the top-selling titles, if they were people we could talk to, we began sending over a stream of controllers. And we would ask them things like concavity or convexity, or trigger pressure, or trigger location, or accuracy, or the like.
"It was extremely helpful to have the designers of some of the top FPSes on our controller design project."
Cerny has previously said that the DualShock 4 has been optimised for first person shooters. Sony's efforts seem to have paid off with Battlefield 4 developer DICE saying the controller is "so much improved" over its predecessor.
