PROBLEM TO BE SOLVED: To provide an interactive display device that enables a simple mode change-over without losing an input area in a normal mode and without leading to a complication of a device.SOLUTION: An image display part 10 displays an image to a display surface. A position detection part 12 detects a position of an object on the display surface. In the normal mode, normal process means 14 draws a line in accordance with a trajectory of the object or moves a displayed icon in accordance with a movement of the object. Mode change-over means 18 determines, in the normal mode, whether or not an attribute of the detected object coincides with a predetermined condition, and changes over to a special mode when the attribute thereof coincides with the predetermined condition. In the special mode, in accordance with a position of the object, special process means 16 performs an adjustment for the image or the detection position, or performs adjustments for both of them. For example, the special process means 16 performs a position calibration. |
