Abstract:
1. A user interface system comprising: a volume of fluid; a membrane including a first region, a second region, and a third region, wherein the first region is interposed between the second and third regions, and wherein the second and third regions are operable between a retracted state and an expanded state, the second and third regions flush with the first region in the retracted state and proud of the first region in the expanded state; a substrate joined to and retaining a portion of the first region of the membrane in planar form, the substrate cooperating with the second region and the third region to define and substantially enclose a first cavity and a second cavity; a pump configured to manipulate a portion of the fluid into the first and second cavities to transition the second and third regions from the retracted state to the expanded state; a tactile layer, separate and distinct from the substrate and the membrane, joined to a portion of the membrane opposite the substrate, and defining a tactile surface touchable by a user, and comprising a deformable area operable between a touch sensor configured to detect a user touch on the tactile surface; and a display separate and distinct from the tactile layer, coupled to the substrate, and configured to output an image through the tactile layer.
