Abstract:
1. A computer implemented method for choosing an intended target element from an imprecise touch on a touch screen display, comprising: defining, a respective bounding box for each of a plurality of elements displayed on the touch screen display, a respective bounding box surrounding a corresponding one of the plurality of elements but not forming part of the corresponding element; determining that a touch point is not within any of the bounding boxes of the plurality of elements on a touch screen display; expanding the bounding boxes of the elements in the plurality of elements based on the determination that the touch point is not within any of the bounding boxes of the plurality of elements, wherein expanding the bounding boxes of the elements comprises causing expanded bounding boxes to overlap; determining that the touch point is within two overlapping expanded bounding boxes of two elements in the plurality of elements; calculating a distance between the touch point and a center of each of the two overlapping expanded bounding boxes of the two elements in the plurality of elements; and choosing a target element from the two elements based on which expanded bounding box of the two overlapping expanded bounding boxes that has the shortest calculated distance between the touch point and the center of the expanded bounding box.
