ABSTRACT:
A pointer remotely points a display screen of a large screen display device. The display screen is picked up by a monitor camera. An image processing unit extracts a feature of the pointer used for pointing based on the resulting image signal to identify the position of the pointing point and the pointer based on the feature. A computer generates information on an object to be displayed at a position pointed by the pointer. The generated information is displayed on a display device (CRT display device or large screen display device) assigned to the pointer. Even when a plurality of pointers are used, the information on the object to be displayed pointed by the pointer is properly displayed.
