Information display system with touch panel
First Claim
1. An information display system for a vehicle navigation system, said information display system having a touch panel for selecting an item by touching the selected item among a plurality of items displayed on a single display screen, comprisingstoring means for storing display data for displaying the plurality of items including one set of typical coordinates indicating a position for each of the items;
- said plurality of items displayed on the display screen being marks displayed on a map so that the coordinates of the displayed items are the locations of the marks on the map;
calculation means for calculating coordinate differences between the typical coordinates for each of the plurality of displayed items and a set of coordinates of a position of a single touch;
select means for selecting the selected item by determining which item of the plurality of displayed items has the least calculated coordinate difference;
deciding means for deciding whether or not a present touch is being made to correct an erroneous selection made from a previous touch; and
probability reducing means, responsive to a decision that the present touch is being made to correct an erroneous selection, for reducing a probability of said select means selecting the previously selected item.

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.

4. An information display system for a vehicle navigation system, said information display system having a touch panel for selecting an item by touching the selected item among a plurality of items displayed on a single display screen, comprising
storing means for storing display data for displaying the plurality of items including one set of typical coordinates indicating a position for each of the items; -
said plurality of items displayed on the display screen being marks displayed on a map so that the coordinates of the displayed items are the locations of the marks on the map; calculation means for calculating coordinate differences between the typical coordinates for each of the plurality of displayed items and a set of coordinates of a position of a single touch; select means for selecting the selected item by determining which item of the plurality of displayed items has the least calculated coordinate difference; deciding means for deciding whether or not a present touch is being made to correct an erroneous selection made from a previous touch; wherein said deciding means decides the present touch to be a correction of an erroneous selection based on conditions that the present touch is within a predetermined time from the previous touch and that the coordinate difference between the previous and present touch positions is within a predetermined range; and probability reducing means, responsive to a decision that the present touch is being made to correct an erroneous selection, for reducing a probability of selecting the previously selected item. - View Dependent Claims (5, 6, 7, 8, 9)
