Abstract: A user input device is provided that includes a button-based control mechanism. The button-based control mechanism includes a button, the button including a user-depressible button top and a button stem, and a button depression guide disposed within an internal cavity of the user input device that engages with the button stem to cause the button to move from a default position and along a substantially arc-shaped path when pressure is applied to the button top. The substantially arc-shaped path may be around an axis of rotation that is external to the user input device. The button-based control mechanism further includes a button biasing mechanism disposed within the internal cavity that returns the button to the default position when the pressure is removed from the button top and at least one sensor that detects actuation of the button responsive to the movement of the button away from the default position.

Abstract: A user-replaceable thumbstick top for a user input device is described. The thumbstick top comprises one or more first mating elements that are adapted to mate with one or more second mating elements of a thumbstick base of the user input device. The first and second mating elements are configured to enable the thumbstick top to be removably connected to the thumbstick base. The manner of interconnection between the thumbstick top and the thumbstick base is such that a user can connect and disconnect the two components without having to disassemble the game controller and without having to use any tools.

Abstract: A user input device is described that includes a thumbstick that comprises a thumbstick module and a thumbstick cap that is connected thereto. The thumbstick cap includes a thumbstick base that is mounted upon the thumbstick module and a thumbstick top that can be removably connected to the thumbstick base. The manner of interconnection between the thumbstick top and the thumbstick base is such that a user can connect and disconnect the two components without having to disassemble the game controller and without having to use any tools.

Abstract: A thumbstick interface ring for a user input device is described. The thumbstick interface ring is adapted to be removably connected to a housing of the user input device. When connected to the housing, the thumbstick interface ring surrounds an aperture included in the housing from which a user-manipulable portion of a thumbstick extends. The thumbstick interface ring serves to prohibit contact between a portion of the thumbstick and an edge of the housing that surrounds the aperture. The thumbstick interface ring may be formed from a material that has a relatively low coefficient of friction with a material from which the portion of the thumbstick is formed. A user can easily disconnect and reconnect the ring to and from the housing without damaging either the ring or the housing.
