Abstract:
1. A user interface system for receiving a user input comprising: a tactile layer including 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, and a displacement device that influences the volume of fluid within the fluid vessel to expand and retract a portion of the fluid vessel in order to deform a particular region of the surface, wherein the tactile layer receives an input on the surface that inwardly deforms the particular region; and a touch sensitive layer arranged substantially underneath the tactile layer and comprising a first layer and a second layer; wherein the first layer is interposed between the tactile layer and the second later, forms a bottom surface of the fluid vessel, comprises a first conductor, and deforms inwardly in response to the input on the surface of the tactile layer, wherein the second layer is coupled to the first layer opposite the tactile layer and comprises a second conductor electrically coupled to the first conductor, and wherein a detectable electrical property between the first conductor and the second conductor changes in response to a change in a distance between the first conductor and the second conductor.
