Abstract

Disclosed is a graphical control that allows scrolling in two dimensions. This invention is intended to solve one scrolling problem, presented below. Scrolling using traditional scroll bars is not efficient. The two scroll bars are not coordinated, and do not provide a coherent picture about the size of the window relative to the size of the document. In addition, the user is forced to scroll horizontally, and then vertically when the operation would be more efficient as a single action in two dimensions.

Two Dimensional Scroll Box

      Disclosed is a graphical control that allows scrolling in two
dimensions.  This invention is intended to solve one scrolling
problem, presented below.  Scrolling using traditional scroll bars is
not efficient.  The two scroll bars are not coordinated, and do not
provide a coherent picture about the size of the window relative to
the size of the document.  In addition, the user is forced to scroll
horizontally, and then vertically when the operation would be more
efficient as a single action in two dimensions.

      This invention provides a single control, called a 2D Scroll
Box.  This box is divided into nine sections, in three rows of three.
The exterior boxes are used for incremental navigation.  The interior
box is used for relative navigation, much like the elevators within a
scroll bar.  The interior box represents the size of the entire
document.  Within the interior box is a shaded box, which represents
the location of the window within the total document.  The shaded box
can be directly manipulated--dragged and dropped at a new location
within the interior box.  As the shaded box is dragged, the window is
updated to reflect the new location within the total document.

      This mechanism provides the traditional incremental vertical
and horizontal controls, in addition to four new angled incremental
controls.  All scrolling functionality is conveniently located within
a small, clearly defined box.
