    generating a zoom command by averaging a sum of up to eight of the plurality of proximity time values from sensors of the plurality of proximity sensors located on opposite sides of the viewing device;

    generating a scroll command by averaging a difference between up to thirty-two of the plurality of proximity time values from the sensors located on opposite sides of the viewing device; and
