    wherein a plurality of control commands are each associated with a unique sliding motion originating with one or more of the finger location regions, and wherein each finger location region is a unique region of the surface;

    (ii) maintaining an association of each of the plurality of control commands with a unique combination of sliding motions and/or non-sliding contacts originating with one or more of the finger location regions, including one control command associated with a sliding motion originating with only the first finger location region and a different control command associated with only a sliding motion with only the second finger location region; and

    (iii) following the positioning of the finger location regions, entering a first control command by discerning a control command input sliding motion at only the first finger location region, determining the direction of the sliding motion, and identifying the first control command based on the finger location region having the motion and the direction of the sliding motion.
