Abstract
A human interactive type dynamic display system including an electronic whiteboard, a pen-like member for marking a point on the whiteboard, and a computer for controlling an image displayed on the whiteboard. On the whiteboard, there is defined an operation region such as a scroll operation region extending along a periphery of the whiteboard. When a user points any point within the scroll operation region with the aid of the pen-like member as a start point, an enable signal for initiating the scroll operation is produced. Then, the displayed image is scrolled in a direction by a distance which are derived by processing a direction and an amount of a dragging operation of the pen-like member on the whiteboard from the start point. Not only the scroll operation, page up and down operation, window shift operation and count value changing operation can be performed in a similar manner.
