Claim Text:
1. A dynamic tactile interface comprising: a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region; a substrate coupled to the peripheral region at an attachment surface of the substrate, the substrate defining a back surface opposite the attachment surface, a fluid conduit adjacent the deformable region, a fluid channel fluidly coupled to the fluid conduit, and a via fluidly coupled to the fluid channel and passing through the back surface; a bladder fluidly coupled to the via and coupled to the back surface of the substrate, the bladder defining a longitudinal axis; a volume of fluid arranged within the bladder; a structure adjacent a first side of the bladder; a platen adjacent a second side of the bladder opposite the first side and compressing the bladder against the structure in a direction substantially perpendicular to the longitudinal axis of the bladder and the platen being translated substantially parallel to the back surface of the substrate to displace fluid from the bladder, through the via, and into the fluid channel to transition the deformable region from a retracted setting into an expanded setting, the deformable region tactilely distinguishable from the peripheral region in the expanded setting; and a first block coupled to and extending from the back surface of the substrate and a second block coupled to and extending from the back surface of the substrate, the second block laterally offset from the first block; wherein the bladder suspends between the first block and the second block, an outer surface of the bladder offset from the back surface, a first end of the bladder coupled to the first block, a second end of the bladder opposite the first end of the bladder coupled to the second block, the longitudinal axis of the bladder substantially parallel the back surface.
