<p>PROBLEM TO BE SOLVED: To provide a virtual keyboard capable of realizing natural input operation the same as a real keyboard, and a touch position determining method for the virtual keyboard. SOLUTION: In this virtual keyboard 11 with a translucent touch panel 12 arranged on a display device 14 displaying a keyboard image an arithmetic device 15 calculates an actual coordinate in a position actually touched or left, based on a one point detected coordinate corresponding to a touch condition of one or a plurality of points of the touch panel 12, from a detection device 13, and an actual coordinate obtained from the detected coordinate just before change of the touch condition, stored in a storage portion, and a recent touch position in the past. Thus, even if a plurality of keys are touched, the actual coordinate of the touched position is precisely calculated, thereby allowing input operation as natural and speedy as a real keyboard.</p> |
