The Xbox One controller is the result of millions of dollars in design efforts and years of testing. Microsoft has long been praised for its ergonomic console controllers, and the Xbox One is no exception. The bumpers and triggers were designed specially for ergonomics, as they were given a new curved shape and their alignment was smoothed. Additionally, the new triggers are each given an independent “Impulse Trigger” so that developers can invoke directional vibration. This is another step in combining tactile feedback with spatial information.
