Abstract

Disclosed is an apparatus whereby in a computer display window, a subwindow containing zoomed image is displayed with a buffer area around it that shows logical relations between the root window image and the subwindow image. The information in the buffer area changes dynamically as displayed image in the root window or in the subwindow is scrolled or zoomed. With this apparatus, a user can get local and global information of the original image at the same time without closing the subwindow.

Apparatus for Displaying Global and Local Information and Their Relation
Dynamically within a Window

      Disclosed is an apparatus whereby in a computer display window,
a subwindow containing zoomed image is displayed with a buffer area
around it that shows logical relations between the root window image
and the subwindow image.  The information in the buffer area changes
dynamically as displayed image in the root window or in the subwindow
is scrolled or zoomed.  With this apparatus, a user can get local and
global information of the original image at the same time without
closing the subwindow.

      Fig. 1 shows typical layout of the root/sub windows and the
buffer area.  Operations such as scrolling and zooming are defined
for both root and sub windows independently, and those operations are
reflected dynamically to the information displayed in the buffer
area.  If a given image has a large horizontal dimension, the layout
may look like Fig. 2.

      Fig. 3 shows an example of the apparatus applied to an
electrical CAD system.  The subwindow displays a zoomed image of
wires and the buffer area around the subwindow indicates logical
connection of wires in the subwindow and those in the root window.
The buffer area need not contain information irrelevant to the
subwindow.  By scrolling or zooming the image in the root window with
the scope of subwindow being fixed, a user can know how particular
wires in the subwindow connect to outer region that was...
