A touch sensitive interface includes a plurality of touch pads that can each register an impedance change indicating a contact. For each contact a plurality of touch pads is identified and within that plurality of associated touch pads one or more seed points is located. Each seed point possesses an input value greater than the input value at each neighboring touch pad. From each seed point within the plurality of touch pads associated with a contact, a region of touch pads is identified. A centroid of each formed region can then be determined to ascertain a touch coordinate.
