Abstract:
1. A haptic control system comprising: a substantially rigid substrate; an elastic screen sheet substantially parallel to the rigid substrate; a first plurality of shape change elements arranged in a first single layer array substantially parallel to and between the substrate and the elastic screen sheet; a second plurality of shape change elements arranged in a second single layer array substantially parallel to the first single layer array, wherein the second array is between the first single layer array and the elastic screen sheet; an intermediate elastic sheet substantially parallel to the rigid substrate, wherein the intermediate elastic sheet is positioned between the first single layer array and the second single layer array; and control circuitry coupled to the first single layer array and the second single layer array; wherein: the first plurality of shape change elements deforms a first region of the elastic screen sheet upon receipt of a first electrical signal; and the second plurality of shape change elements deforms a second region of the elastic screen sheet upon receipt of a second electrical signal.
