<p>PURPOSE:To improve response speed by enabling the next operation before switching a display picture to the next selected picture by recognizing one time of operation, continuously storing and reading plural coordinate positions by detecting that a finger is separated from a touch panel. CONSTITUTION:When a part A of a touch panel 31 is touched in the state of displaying a selected picture 1 on a display 21, a coordinate transformation part 41 holds this coordinate position and when the finger is separated from the touch panel 31, the coordinate position of A is stored in a coordinate information storage part 42. Next, when a part F is touched earlier than the display of a selected picture 2, the coordinate position of F is stored in the coordinate storage part 42. Since the coordinate storage part 42 continuously outputs the coordinate positions of A and F under the control of a host computer, the host computer displays a selected picture 3 while regarding that the display to the selected picture 2 is finished. Thus, the desired selected picture can be speedily displayed.</p> |
