<p><P>PROBLEM TO BE SOLVED: To provide a navigation device capable of many operations by touch operation for drawing a diagram while touching. <P>SOLUTION: Two arbitrary points 32a, 32b on a display screen are touched by two fingers. Then, while maintaining one point touch position 32a of them, another touch position 32b is moved as drawing a straight line in a desired scroll direction (direction of an arrow 33). As a result, a map 30 is scrolled by a predetermined amount in the direction of arrow 34 which is the same direction of arrow 33. Moreover, when the two touch positions are moved to narrow the spacing between them after the two arbitrary touch positions 32a, 32b are touched by two fingers, the map 30 changes to a wide-area map, and when the spacing is widen, the map 30 changes to a detailed map. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
