Claim:
1. A dynamic tactile interface with an anti-reflective coating comprising: a tactile layer defining a first region and a deformable region adjacent the first region; a substrate coupled to the tactile layer at the first region, defining a variable volume adjacent the deformable region and defining a fluid channel fluidly coupled to the variable volume; a set of rigid structures distributed across the tactile layer and over the tactile layer, the set of rigid structures comprising a first subset of rigid structures coincident the first region and a second subset of rigid structures coincident the deformable region, wherein: a displacement device fluidly coupled to the fluid channel, the displacement device displacing fluid into the fluid channel to transition the deformable region from a retracted setting to an expanded setting, the deformable region tactilely distinguishable from the first region in the expanded setting, the second subset of rigid structures conforming to the deformable region, each rigid structure in the second subset of rigid structures shifting relative to an adjacent rigid structure in the second subset of rigid structures and shifting relative to each rigid structure in the first subset of rigid structures, the first subset of rigid structures conforming to the first region.
