Abstract

Disclosed is a graphical interface scheme for scrolling in two dimensions. Scrolling in 2 dimensions using traditional scroll bars is not efficient. The user must scroll horizontally and vertically in two distinct steps. This is especially annoying when a user is exploring a document, spread sheet, or large graphical image. This problem can be solved by providing some logical extensions to existing vertical and horizontal scroll bars.

Two Dimensional Scrolling Extension

      Disclosed is a graphical interface scheme for scrolling in two
dimensions.  Scrolling in 2 dimensions using traditional scroll bars
is not efficient.  The user must scroll horizontally and vertically
in two distinct steps.  This is especially annoying when a user is
exploring a document, spread sheet, or large graphical image.  This
problem can be solved by providing some logical extensions to
existing vertical and horizontal scroll bars.

      Provide an extension to tie the two scroll bars together.
Specifically, when the user does a single mouse click on a scroll bar
elevator without moving it, then a new elevator wire frame is
superimposed on the document, immediately above the horizontal scroll
bar elevator, and beside the vertical scroll bar.  The new elevator's
width is the same as the width of the horizontal elevator; the height
is the same as the vertical elevator.  This elevator can now be
directly manipulated to scroll in two dimensions.  As the location of
the 2d elevator changes, the vertical and horizontal scroll bar
elevators as well as the contents of the window are updated.  For
graphics applications, direct manipulation of the sides of the wire
frame can be used to "zoom in" and "zoom out" on a large graphical
image.
