Abstract

A dynamic tactile interface includes: a substrate including a first transparent material and defining an attachment surface, an open channel opposite the attachment surface, and a fluid conduit intersecting the open channel and passing through the attachment surface; a tactile layer including a second transparent material and defining a tactile surface, a peripheral region bonded to the attachment surface opposite the tactile surface, and a deformable region adjacent the fluid conduit and disconnected from the attachment surface; a closing panel bonded to the substrate opposite the attachment surface and enclosing the open channel to define a fluid channel; a working fluid; and a displacement device configured to displace the working fluid into the fluid channel and through the fluid conduit to transition the deformable region from a retracted setting to an expanded setting.
