Abstract
A dynamic tactile interface including 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 defining an anti-reflective coating over the tactile layer; and 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 set of rigid structures conforming to the tactile layer, each rigid structure in the set of rigid structures shifting relative to an adjacent rigid structure in the set of rigid structures.
