Method and apparatus for choosing an intended target element from an imprecise touch on a touch screen display
Abstract:
A method and apparatus for an improved workflow for choosing an intended target element from an imprecise touch on a touch screen display comprises determining whether a touch 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; determining whether the touch is within the expanded bounding box of at least one element in the plurality of elements; calculating a distance between the touch and a center of the bounding box for at least two elements in the plurality of elements, wherein the touch is determined to be within the expanded bounding box of the at least two elements; and determining a target element based on the shortest calculated distance between the touch and a center of the bounding box of the at least two elements.
