Dynamic tactile interface
One variation of a dynamic tactile interface includes: a substrate defining a fluid channel and a fluid conduit fluidly coupled to the fluid channel; a tactile layer comprising a peripheral region and a deformable region, the peripheral region coupled to the substrate, and the deformable region arranged over the fluid conduit, disconnected from the substrate, and operable between a retracted setting and an expanded setting, the deformable region elevated above the peripheral region in the expanded setting; a tube comprising a first end fluidly coupled to the fluid channel and constrained relative to the substrate; a volume of fluid within the tube; and a rotary actuator coupled to the tube remote from the first end and configured to transition the deformable region from the retracted setting to the expanded setting by winding the tube to displace a portion of the volume of fluid within the tube into the fluid channel.
