Abstract

A method and apparatus is disclosed herein for mapping a touch sensing device to two sets of output objects. In one embodiment, the method includes mapping a first set of output objects into a plurality of one dimensional positions of a touch-sensor device when a movement of a presence of a conductive object is determined to be in a first direction across the touch-sensor device. The method further includes mapping a second set of output objects into the plurality of one dimensional positions of the touch-sensor device when the movement of the presence of the conductive object is determined to be in a second direction, distinct from the first direction, across the touch-sensor device.
