<p>PROBLEM TO BE SOLVED: To provide an information processor using a touch-panel display 10 enabling a complex input process to be carried out through a simple operation. SOLUTION: When a user brings his thumb and index finger into contact respectively with points 11 and 12 on the touch panel display 10 to sandwich an item 2 displayed on an LCD and then narrows the interval between them, a circle C with a diameter L whose center O is located at the mid point between the two contact points 11a and 12a is set when the narrowed interval between the contact points 11a and 12a is reduced below a threshold value L. The item 2 located inside the circle is recognized as a displayed item to be operated. When the points 11b and 12b are moved to the contact points 11a and 12a, accordingly the item 2 is moved to a point 13. When the user moves his fingers away from the display 10, the destination of the item 2 is determined to be the point 13. A dragging function can thus be provided.</p> |
