<p>PURPOSE:To enable the user to use the image of the shape of the user's own hand as a cursor for executing pointing operation. And also, to compensate the deviation between the coordinate of a camera image and the coordinate of a touch sensor so that the user can accurately output coordinate data of a position that the user desires to obtain. CONSTITUTION:A signal for image 17 of the user's hand is superimposed on an image signal to be prepared by a controller section 11, and accordingly, the image 17 of the user's hand is displayed on the screen 16 of display 15 in such a state that the image 17 is superimposed on the image 18 formed by the controller section 11. Even if deviation occurs between the coordinate of camera image area AR1 and the coordinate of touch panel 1, calibration operation for compensating the coordinate deviation is automatically done by detecting a marker 3.</p> |
