1. A computer implemented method for choosing an intended target element from an imprecise touch on a touch screen display, comprising:

  • determining whether a touch point is within a bounding box of precisely one of a plurality of elements on a touch screen display;

    expanding the bounding box of all of the elements in the plurality of elements when the touch point is not within the bounding box of precisely one of the plurality of elements;

    determining whether the touch point is within the expanded bounding box of at least one of the elements in the plurality of elements;

    calculating a distance between the touch point and a center of the bounding box of at least two elements in the plurality of elements, wherein the touch point is determined to be within the expanded bounding box of the at least two elements; and

    choosing a target element based on the shortest calculated distance between the touch point and a center of the bounding box of the at least two elements in the plurality of elements, wherein the touch point is determined to be within the expanded bounding box for the at least two elements.
