Abstract

An interactive cord can include a plurality of non-conductive lines and a plurality of conductive lines arranged together in a first longitudinal portion to form a touch-sensitive area within a first longitudinal portion of the interactive cord. A non-touch-sensitive area can be formed in a second longitudinal portion such in which the plurality of conductive lines is not exposed along an outer surface of the outer layer. The plurality of conductive lines can be arranged together with the one or more of the plurality of non-conductive lines within a third longitudinal portion. The second longitudinal portion can be arranged between the first longitudinal portion and the third longitudinal portion with respect to a longitudinal direction of the interactive cord. The third longitudinal portion can be open along the longitudinal direction to form a pair longitudinal edges of the outer layer that extend in the longitudinal direction of the interactive cord.
