<p>PURPOSE:To correct an input error even when the view point of an operator is shifted from directly in front of a screen by converting a detected position coordinate outputted from a touch screen to the image coordinate of a display device based on relative relation obtained by a coordinate position conversion arithmetic means. CONSTITUTION:By inputting the view point position of the operator by operating parallax correction value input means 7a-7c by the operator, etc., a coordinate position relation arithmetic means 11 operates the relative relation between the image coordinate of the display device 2 and the detected plane coordinate of the touch screen 3 based on data inputted from the parallax correction value input means 7a-7c. And the coordinate position conversion means 11 converts the detected position coordinate outputted from the touch screen 3 to the image coordinate of the display device 2 based on the relative relation. In such a way, it is possible to perform correction on the input error even when the view point of the operator is shifted just front of the screen.</p> |
