ABSTRACT:
An information display system has a touch panel for selecting an item from a plurality of displayed items by touching. Coordinate differences between each of the coordinates of the plurality of displayed items and the touch position coordinates are calculated. The item having the least calculated coordinate difference is the selected item. Subsequent touchings within a predetermined time and distance are determined to be attempts to correct previous erroneous selections causing probabilities of selecting the previously selected items to be reduced, such as by changing relative calculated coordinate differences to favor selection of other items. Alternatively, a next candidate button can be touched to select the item with the next least coordinate difference.
