Abstract
A touch screen comprising a flexible sheet comprising a substantially planar surface and integral compressible spacer dots formed thereon, where each spacer dot comprises a base cross section in the substantially planar surface of the flexible sheet defined by a first point or set of connected points intersecting an axis in the substantially planar surface, a second opposed point or set of connected points intersecting the axis, and first and second continuous edge segments connecting the first and second points or end points of the first and second sets of points on opposite sides of the axis, wherein the spacer dot has a variable height perpendicular to the substantially planar surface along the axis, and wherein the surface of the spacer dot extending above the base cross section is not equidistant from the mid-point of the axis between the intersections of the first and second points or sets of connected points and the axis.
