Abstract
An interactive cord includes one or more touch-sensitive areas configured to detect user input and one or more non-touch-sensitive areas. An outer cover of the interactive cord includes a set of conductive lines braided together with one or more of a plurality of non-conductive lines at the touch-sensitive area. The set of conductive lines defines a plurality of intersections that each form a capacitive touchpoint at the touch-sensitive area. An inner core of the interactive cord includes at least the set of conductive lines and at least one of the plurality of non-conductive lines at the non-touch-sensitive area.
