A touch sensor is provided that includes an array of discrete electrodes disposed over a touch sensitive area, the electrodes being elongated in a first direction and having a variable width measured in a second direction that is perpendicular to the first direction. A touch location can be determined by simultaneously applying an electrical signal to a plurality of positions on the touch sensor, the touch location along the first direction being determined by comparing a capacitive coupling between the touch implement and the plurality of positions in the touch sensor, and the touch location along the second direction being determined by comparing a resistive coupling between the touch implement and the plurality of positions in the touch sensor.
