The Xbox One controller is the main controller for the Xbox One. The controller maintains the overall layout found in the Xbox 360's controller, but with various tweaks to its design, such as a slightly revised shape, redesigned analog sticks, shoulder buttons, and triggers. The triggers have new vibrators within the triggers to allow for directional haptic feedback.
Since the Xbox One's launch on November 22, 2013, there has been only one minor revision to the Xbox One controller that adds a 3.5mm stereo headset jack and features an improved mechanism in its bumpers.
The Xbox One controller has been changed grately compared to the Xbox 360 Controller. The triggers are now rounded, and have four vibration motors - a small one behind each trigger that adds precise aptic feedback to the fingertipsm and a larger one in each grip for large scale rumbles. This will give users a sense of in-game direction and depth, creating rich, immersive experiences where gunshots, car crashes and explosions can feel ever so realistic.
The new thumbsticks on the Xbox One controller have been made smaller, and have a knurled texture for better grip. The new thumbsticks now require 25% less force to move.
These A,B,X,Y buttons also have a new design, giving them a 3D look, they are also places lower down on the controller and are closer together.
The headset jack has changed from the Xbox 360 and old headsets will not work with the new controller. The new controller will be able to be charged with a USB wire, from the console to the controller.
The new Xbox One Controller now has a "low power state". This senses when you are not holding the controller and will put the controller to sleep to save battery life. The moment you pick the controller up, it will awake.
The controller now has better connectivity to the console, making chatting more clearer and alot more quicker. Xbox have claimed this is now clearer and faster than talking on a phone.
