Embodiments are directed to an input device and methods related to the use thereof. The embodiment may include a deformable structure. The deformable structure may include a first layer defining an input surface and a second layer coupled to, and offset from, the first layer. At least one of the first layer or the second layer may define a geometric feature (e.g., including a protrusion, embossed portion, or other feature of one or both of the first and second layers). The geometric feature may be configured to collapse the deformable structure at a localized region in response to a force input. The embodiment may further include an input structure configured to produce an electrical response based on a magnitude of the force input.
