<p>PROBLEM TO BE SOLVED: To enable visually sure and easy double click by judging the input as a double click in 1st coordinates in the case where the 1st coordinates are inputted and then a 2nd coordinates are inputted to the same data input area as the 1st coordinates within a prescribed time. SOLUTION: If a tablet 18 is pushed by a pen 19 and one point in a picture displayed in a liquid crystal display 13 is directed, an input area to which the 1st coordinates belong is defined and a timer is started using a clock obtained from a real-time clock 20. If the 2nd input by the pen 19 comes within the prescribed time limit of the timer, it is judged whether the 2nd coordinates is within a double-click effective range, and if it is within the effective range, it is judged that the 1st coordinates are double-clicked. Thus, the same function as a double-click of mouse is realized by the pen 19 or touch input, moreover, a problem of position shift which is apt to cause from inputting by the pen 19 is solved, and double click at two distant points is realized.</p> |
