10. A computer-implemented method comprising: providing an item for output at a first location on a proximity-sensitive display; receiving data indicating a touch received at a second location on the proximity-sensitive display; determining a confidence value that reflects a mapping engine's confidence that the item accurately represents an input; determining whether the touch received through the proximity-sensitive display represents a selection of the item based at least on (i) the confidence value that reflects the mapping engine's confidence that the item is an accurate representation of the input, (ii) the first location of the item on the proximity-sensitive display, and (iii) the second location of the touch on the proximity-sensitive display; and providing an indication of whether the touch received through the proximity-sensitive display represents a selection of the item.
11. The computer-implemented method of claim 10 , comprising: providing another item for output at a third location on the proximity-sensitive display; determining a confidence value that reflects the mapping engine's confidence that the other item accurately represents another input; wherein determining whether the touch received through the proximity-sensitive display represents a selection of the item based at least on (i) the confidence value that reflects the mapping engine's confidence that the item is an accurate representation of the input, (ii) the first location of the item on the proximity-sensitive display, and (iii) the second location of the touch on the proximity-sensitive display, comprises determining whether the touch received through the proximity-sensitive display represents a selection of the item based at least on (i) the confidence value that reflects the mapping engine's confidence that the item is an accurate representation of the input, (ii) the first location of the item on the proximity-sensitive display, (iii) the second location of the touch on the proximity-sensitive display, (iv) the confidence value that reflects the mapping engine's confidence that the other item is an accurate representation of the other input, and (v) the third location of the other item on the proximity-sensitive display.
