ABSTRACT:
A computer user interface that represents information stored in a computer as reprentation objects located on at least one reference surface is disclosed. A user can magnify or reduce the displayed information by "zooming" in or out. The magnification operation displays a smaller portion of a particular surface, but each object that remains in view is displayed in greater size and/or detail. Similarly, the reduction operation displays a larger portion of a given surface, but each object within such surface is displayed in a smaller size and/or less detail. In order to view one part of the surface from another part of the surface or from another surface, a special type of an object, called a representation portal object, is provided. A graphical description of each object is physically stored in computer memory essentially as a sequence of compressed image representations. The first image in the sequence is a bit-mapped representation of an object as it was created, and each subsequent image is a reduced copy of the first image.
