ABSTRACT:
A display system comprises a data base memory for storing data representing a picture, a display device for displaying the picture, and manipulation means for causing the display device to display a cursor at a position which is under user control. The picture is composed of objects and each object is represented in the data base memory by a segment which represents both the object and the position of the object in the picture. A pointer, which divides the address domain of the display device into at least two regions, is generated. The manipulation means provides a signal which identifies the region of the pictures in which the cursor is positioned, and this signal is compared with the contents of the data base memory to facilitate selection of an object which lies in the identified region of the picture.
