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.
