The user interface system and method

One embodiment of a user interface system comprising: a tactile layer, defined by the user may touch the touch surface and a plurality of deformable regions, deformable region between a contracted state and an expanded state is operable in a contracted state, deformable region may be non-deformable region flush with the tactile layer; and in the expanded state, the deformable region comparing non-deformable region. The substrate is bonded to the non-deformable zone and the fluid passage defining a fluid port and each deformable region. Displacement device of displacement fluid through the fluid channel and the fluid port, such that the deformable region of transition from the contracted state to the expanded state. Changes in fluid pressure within the fluid detected by the deformable region may be applied to a specific force due to the first and second pressure sensors in. The processor may be a specific variation deformable region determined based on the position of the input force to fluid pressure detected.
