ABSTRACT:
A system for creating and manipulating groups of graphic objects using enclosures. A persistent graphic object, such as a closed loop is drawn around a set of graphic objects as an enclosure. When the enclosure is selected the enclosure and the set of graphic objects within are grouped. Besides moving graphic objects into and out of the enclosure, the contents of a group can then be modified by 1) graphically altering the enclosure loop to include or remove graphic objects, 2) fusing groups by moving one of them so that their enclosure loops overlap (i.e., they "fuse" into one), 3) fusing groups through gestures which "touch" enclosure loops of the groups to be fused or 4) splitting the group into multiple groups through a splitting gesture.
