An articulated controller is provided that enables a user to simply, and intuitively enter complex movements into a game with high accuracy, and while maintaining a constant grip. The controller comprises: a first hand unit, for being held in one hand by the user; a second hand unit, for being simultaneously held in another hand by the user, and an articulable joint coupling the first hand unit and the second hand unit, wherein the articulable joint is at least partly enclosed by the first hand unit to enable the user to maintain a grip on the first hand unit without interference from the articulable joint, and wherein user input is provided to the controller through movement of the articulable joint.
