Abstract: Described herein are, among other things, handheld controllers that include one or more touchpads (i.e., touch-sensitive controls) configured to detachably couple to one or more overlays that effectively transform the respective touchpad into a different control. For instance, one example handheld controller may include a circular trackpad that is configured to detect a position of a finger on a top surface of the trackpad. This position may be used to control a cursor or avatar, for scrolling, or for any other type of command. In general, most or all of the top surface may be usable by a user for providing input to the controller and/or a remote system coupled to the controller. As described herein, however, one or more different overlays may detachably couple to a housing of the controller and/or the trackpad itself to effectively change the use of the trackpad.

Abstract: Described herein are, among other things, handheld controllers that include housings having one or more receiver portions for detachably coupling to one or more controls. For example, a housing of one such controller may include, on a front surface of the housing, a receiver that is configured to detachably couple to one or more joysticks, one or more D-pads, one or more track pads, one or more buttons, and/or the like. In some instances, a user may swap a first control for a second control based on a current application (e.g., game title) that the user is playing, based on comfort of the user, and/or for any other reason.
