Claim:
1. A user interface system comprising: a substrate defining a fluid channel comprising a first end and a second end, the fluid channel fluidly coupled to a set of cavities between the first end and the second end; a tactile layer comprising a tactile surface, a peripheral region coupled to the substrate, and a set of deformable regions adjacent the peripheral region, each deformable region in the set of deformable regions cooperating with the substrate to define a corresponding cavity in the set of cavities; a first pressure sensor fluidly coupled to the fluid channel proximal the first end; a second pressure sensor fluidly coupled to the fluid channel proximal the second end, the second pressure sensor discrete from the first pressure sensor, the set of deformable regions defined between the first pressure sensor and the second pressure sensor; and a processor comparing a first signal from the first pressure sensor and a second signal from the second pressure sensor to determine a location of an input on the tactile surface at a particular deformable region in the set of deformable regions.
