1. A touch sensor for determining position of a touch on a three dimensional object, the touch sensor comprising:

  • pluralities of first and second electrodes and an insulator between the first and second electrodes, the first and second electrodes and the insulator being mounted to a surface of the three-dimensional object,the plurality of first electrodes being arranged in a first direction, andthe plurality of second electrodes being arranged in a second direction different from the first direction such that the first and second electrodes cross over each other to form touch sensing nodes at three-dimensional locations relative to the object; and

    a processor configured to process a signal from one or more of the electrodes representing the touch at one or more of the sensing nodes, to determine a position of the touch on the three dimensional object.
