Abstract

This article describes a new user interface method for moving and scaling a rectangular area on the screen of an interactive system, such as an image/graphics editing system and a multiwindow system. In the proposed method, a target rectangular area is divided into several sub-areas. One of the move and scale commands is assigned to each sub-area, which is issued when a user drags inside the corresponding sub-area. A user can move or scale it by dragging inside one of the sub-areas. Fig. 1 shows an example of the rectangular area. In this example, the rectangular area is divided into 9 sub-areas, and it is, for example, enlarged/shrunk in left-upper/right-lower direction when a user drags inside the left-upper sub-area by using a pointing device as the arrow-shaped icon shows.
