<p><P>PROBLEM TO BE SOLVED: To provide a screen operating device capable of surely performing operations matching the intention of an operator. <P>SOLUTION: In this car navigation device 10, when a finger touching a touch panel presses the touch panel with a pressing force larger than a specified level or higher, and an enter signal is inputted to a CPU 18, the CPU18 reads a touch signal stored in a RAM 20 beforehand, and the read touch signal is converted into a touch signal corresponding to the enter signal. By this, even if the contact area of the finger on the touch panel is increased with a pressing reaction produced when the finger presses the touch panel and accordingly the tip position and the area of the center of gravity position of the finger contact portion change on the touch panel, the touch signal after the change is basically neglected without being adopted. As a result, a program which does not match the intention of the operator is not started. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
