Multi-Directional Scroll Method for Navigating in a Seemingly Boundless Two Dimensional Area

      Provided is a method for navigating in a two dimensional area
with unknown boundaries when viewed by a user (e.g., infinite desktop
system).

      An infinite desktop system requires a convenient method for
navigation.  A mouse operated method is needed.  As shown in Figure,
a scroll bar icon is implemented on the desktop.  The icon can be
spawned to a work area such as a desktop and dragged to a preferred
place like any other icon.  The icon is manipulated with a mouse.
Associated with the scroll bar icon is a configuration interface
available upon request by a user through double clicking on the slide
bar of the icon.  Configuration permits a user to set distance
scrolled when selecting any of the scrolling arrow heads (e.g., one
inch, 3 millimeters, etc.).  A user may position the mouse cursor on
the double arrow headed arcs for rotating the scroll bar.  Dragging
the scroll bar by the arc causes the scroll bar to rotate upon a
central axis about a center point at the center of the icon.  Drag
movement to the right rotates right.  Drag movement to the left
rotates left.  Clockwise or counterclockwise is determined by which
arc is dragged, uppermost or bottommost and which direction it is
dragged.  The slide bar rectangle is dynamically updated according to
the orientation of the icon when being rotated.  The slide bar always
represents the position of th...
