Claim:
1. A user interface comprising: a substrate defining a cavity and a fluid channel fluidly coupled to the cavity; a tactile layer comprising a first region and a deformable region adjacent the first region, the first region coupled to the substrate, the deformable region adjacent the cavity, a first portion of the deformable region adjacent the first region, a second portion of the deformable region adjacent the first portion of the deformable region and coincident a center of the deformable region, the tactile layer defining a tactile surface across the deformable region and the first region and opposite the substrate, the first region exhibiting a first flexibility, and the second region exhibiting a second flexibility greater than the first flexibility across the tactile surface, wherein the tactile layer at the deformable region defines a second thickness greater than the first thickness across the first region; and a displacement device displacing fluid through the fluid channel and into the cavity to transition the deformable region from a retracted setting to an expanded setting, the deformable region substantially flush with the first region in the retracted setting and defining a tactilely distinguishable formation offset above the first region in the expanded setting.
