User interface system

Abstract

Disclosed is a user interface system that includes a sheet that defines a surface and at least partially defines a fluid vessel arranged underneath the surface, a volume of fluid within the fluid vessel, a displacement device that influences the volume of the fluid within the fluid vessel to expand and contract at least a portion of the fluid vessel, thereby deforming a particular region of the surface, and a sensor system that is configured to receive a user input on the surface with a first sensitivity and configured to receive a user input substantially proximal to the particular region of the surface at with second sensitivity higher than the first sensitivity.

We claim: 
     
         1 . A user interface system, comprising:
 a sheet that defines a surface and at least partially defines a fluid vessel arranged underneath the surface;   a volume of fluid within the fluid vessel;   a displacement device that influences the volume of the fluid within the fluid vessel to expand and contract at least a portion of the fluid vessel, thereby deforming a particular region of the surface; and   a sensor system configured to receive a user input on the surface with a first sensitivity and configured to receive a user input substantially proximal to the particular region of the surface at with second sensitivity higher than the first sensitivity.
