Abstract

Disclosed is an idea of graphical user interface which enables dynamic page scrolling by using concurrently displayed multi windows on a display screen. In order to manipulate a document in computer system, certain method of page scrolling must be provided by the system because the document usually consist of multiple pages. When a user work with a page of the document, it is often the case that the system is to practically display only a part of the page due to the limitation by resolution and size of the physical display.

Method of Dynamic Page Scrolling Using Concurrently Displayed Multi
Windows on a Screen

   Disclosed is an idea of graphical user interface which
enables dynamic page scrolling by using concurrently displayed multi
windows on a display screen.  In order to manipulate a document in
computer system, certain method of page scrolling must be provided by
the system because the document usually consist of multiple pages.
When a user work with a page of the document, it is often the case
that the system is to practically display only a part of the page due
to the limitation by resolution and size of the physical display.  To
provide a page scrolling method with ease-of-use in the limited
resolution and size of the display, an adopted design is for the
screen to be logically divided into two areas : 1) Main-area which
shows a part of a page of a document enough enlarged as readable, and
2) Sub-area which can contain windowed image of the entire page by
reduced resolution.  The sub area may contain more than one window to
show images of other pages adjacent to the page displayed in the
main-area.  Another concept introduced is for the sub-area to have a
indicating frame which indicates the part of the page displayed in
the main-area.  (Fig.1)

   The idea invented is to have the indicating frame work as
a controller pad for specifying the enlarged image area displayed in
main-window which specification can apply beyond page boundaries.
The function of the indicating frame consists of the following
schemes.
  1) When the sub-area has sub-windows for a page which is
     displayed in the main-window (current page) and adjacent
     pages, and the indicating frame is dragged from the current
     page into an adjacent page, the indicating frame moves to
     the newly specified sub-window while enlarged image in
     main-window is changed to present the area of the page
     corresponding to newly specified location of the indicating
     frame.  (refer to IBM PAT: JA997-028)
  2) When the document has many pages, not all of the pages can
     be displayed in sub-area.  In that case, lim...
