USER INTERFACE SYSTEM
A user interface system including a sheet that defines a surface and at least partially defines a first level fluid vessel arranged at a first level within the sheet and a second level fluid vessel arranged at a second level within the sheet, wherein both the first and second level fluid vessels are arranged underneath the surface; a first volume of fluid contained within the first level fluid vessel; a second volume of fluid contained within the second level fluid vessel; and a displacement device coupled to the first and second level fluid vessels that selectively manipulates the first and second volumes of fluid, thereby deforming a particular region of the surface to a first and second stage, respectively or deforming a first particular region and a second particular region of the surface, respectively.
1 . A user interface system comprising:
a layer defining a surface and an attachment surface and comprising a deformable portion;
a first substrate comprising a particular portion, defining a first fluid vessel, and coupled to the layer at the attachment surface, the deformable portion of the layer and the first substrate cooperating to define a first cavity at a first depth from the surface and fluidly coupled to the first fluid vessel;
a second substrate coupled to the first substrate and defining a second fluid vessel, the first substrate and the second substrate cooperating with the particular portion of the first substrate to define a second cavity at a second depth from the surface and fluidly coupled to the second fluid vessel; and
a displacement device fluidly coupled to the first fluid vessel and the second fluid vessel, selectively manipulating fluid in the first fluid vessel into the first cavity to transition the deformable portion of the layer from a retracted setting to an expanded setting tactilely distinguishable from the surface, and selectively manipulating fluid in the second fluid vessel into the second cavity to deform the particular portion and the deformable portion from the retracted setting to a second expanded setting.
