USER INTERFACE SYSTEM

A user interface system for a device that includes a first deformable layer that with a first sheet that defines a first surface, a first fluid vessel arranged underneath the first surface, and a first volume of fluid contained within the first fluid vessel that is manipulated to deform a first particular region of the first surface to receive a user input; a second deformable layer with a second sheet that defines a second surface, a second fluid vessel arranged underneath the second surface, and a second volume of fluid contained within the second fluid vessel that is manipulated to deform a second particular region of the second surface to change the shape of the device; and a displacement device a displacement device coupled to at least one of the first and second fluid vessels and configured to manipulate the volumes of fluid to deform particular regions of the surface.
