Abstract:
1. A user interface comprising: a layer comprising a singular structure defining a cavity, a fluid channel, and a tactile surface, the tactile surface defining a deformable region adjacent the cavity and a peripheral region adjacent the deformable region, the tactile surface continuous over the deformable region and the peripheral region, the fluid channel configured to communicate fluid in a direction substantially parallel to the tactile surface at the peripheral region; a support member extending into the cavity and configured to support the deformable region against inward deformation, the support member defining a lattice structure comprising a set of fluid conduits configured to fluidly couple the fluid channel to the cavity; a displacement device configured to transition the deformable regional between a retracted setting and expanded setting by displacing fluid through the fluid channel and into the cavity via the set of fluid conduits, the tactile surface at the deformable region flush with the tactile surface at the peripheral region in the retracted setting, the tactile surface at the deformable region offset from the tactile surface at the peripheral region in the expanded setting; and a sensor coupled to the layer and configured to detect an input on the tactile surface.
