User interface system
First Claim
1. A user interface system comprising:
- a tactile layer defining a tactile surface a first region, and a deformable region adjacent the first region;
a permeable layer comprising an attachment area and a support surface adjacent the attachment area, the permeable layer defining a substantially uniform density of fluid ports across the attachment area and the support surface, the peripheral first region coupled to the attachment area and Mocking flow of a fluid through fluid ports within the attachment area, the deformable region arranged over and disconnected from the support surface;
a retaining wall coupled to the permeable layer opposite the tactile layer and impermeable to the fluid;
a displacement device configured to displace the fluid through fluid ports within the support surface by displacing a portion of the permeable layer relative to the retaining wall to transition the deformable region from a retracted setting to an expanded setting, the deformable region in contact with the support surface in the retracted setting, the first region elevated above the first region and lifted off of the support surface in the expanded setting; and
a sensor configured to output a signal corresponding to an input on the tactile surface.

Abstract
One embodiment of the user interface system comprises: a volume of fluid; a tactile layer; a retaining wall substantially impermeable to the fluid; a permeable layer; a displacement device; and a touch sensor. The tactile layer, with a back surface, defines a second region, operable between: a retracted state, wherein the second region is substantially flush with a first region; and an expanded state, wherein the second region is substantially proud of the first region. The permeable layer, joined to the back surface of the first region, includes a plurality of fluid ports that communicate a portion of the fluid through the permeable layer to the back surface of the second region. The displacement device directs the fluid through the fluid ports to the back surface to transition the second region from the retracted state to the expanded state. The touch sensor detects a user touch on the tactile layer.
