Abstract:
1. A user interface comprising: a substrate comprising an attachment surface, defining a cavity adjacent the attachment surface, and defining a fluid channel fluidly coupled to the cavity, the cavity comprising a first drafted wall including a particular draft angle; a tactile layer comprising a tactile surface, a first region, and a deformable region, the first region coupled to the attachment surface at an attachment point, the tactile surface is opposite the substrate, and the deformable region disconnected from the substrate and comprising a portion extending into the cavity and defining a second drafted wall including the particular draft angle; a displacement device configured to displace fluid through the fluid channel and into the cavity to transition the deformable region between a retracted setting and an expanded setting, the deformable region defining a first tactile formation at the tactile surface and the second drafted wall in contact with the first drafted wall in the retracted setting, and the deformable region defining a second tactile formation different from the first tactile formation at the tactile surface and the second drafted wall elevated off of the first drafted wall in the expanded setting; and a sensor coupled to the substrate and configured to detect an input on the tactile surface.
