1. A dynamic tactile interface comprising:

  • a substrate comprising an attachment surface, a cavity, and a fluid channel fluidly coupled to the cavity, the cavity defining a curvilinear cross-section;

    a pedestal arranged within the cavity, pivotable within the cavity, and comprising a mating surface and an exterior surface;

    a tactile layer comprising a peripheral region coupled to the attachment surface, a deformable region adjacent the peripheral region and arranged over the pedestal, and a tactile surface opposite the substrate;

    a displacement device displacing fluid into the fluid channel and into the cavity to transition the deformable region from a retracted setting into an expanded setting, the mating surface of the pedestal in contact with the cavity and the pedestal pivotable within the cavity between a first position and a second position in the retracted setting, the deformable region flush with the peripheral region in the first position and defining a first formation tactilely distinguishable from the peripheral region in the second position, and the pedestal partially elevated out of the cavity and the deformable region defining a second formation tactilely distinguishable from the first formation and the peripheral region in the expanded setting; and

    a sensor coupled to the substrate and outputting a signal corresponding to an input on the tactile surface.
