Claim 8:
9. The keyboard system of claim 1:
wherein the tactile layer comprises an elastic sublayer arranged over the substrate and a set of discrete rigid key elements; and
wherein each discrete rigid key element, in the set of discrete rigid key elements:
is coupled to a discrete region of the elastic sublayer over an inductor in the array of inductors;
defines a key location in the array of key locations;
houses a magnetic element in the array of magnetic elements; and
is configured to compress the discrete region of the elastic sublayer and to move the magnetic element toward the inductor responsive to application of a force on the discrete rigid key element, the magnetic element inducing current flow through the inductor responsive to motion toward the inductor.
