One of the coolest features of the Xbox One controller are the impulse triggers. These additional rumble motors exist in each shoulder button, giving the controller a unique feel. Forza Motorsport 5 will take advantage of the triggers, giving players an additional way of feeling feedback from the car.
Turn 10 creative director Dan Greenawalt explains that with the new rumble feature, "you feel the ABS.
You can feel the tires lock up while you're braking." And because the game's physics engine determines how much force is being generated, they can "dial it up when you're beyond the threshold of your tires," giving you a real kick in the hands.
The end result will make for a better translation of virtual driving into real driving. It should also help train gamers, who typically operate "digitally" into thinking "analog." Hands-on with the controller is the only real way to appreciate the new controller's rumble feature, but this exciting new video from Xbox should suffice for now:
