Mouse Assisted Scrolling Function for Multimedia Displays

      A method of using a "mouse" type of display station pointer
device to control scrolling on the display station is disclosed.  The
scrolling is in an arbitrary direction within a two-dimensional
domain.  The rate or distance of scrolling or panning is also
controllable.

      This invention makes use of the position on a display screen of
a mouse controlled cursor to control the direction and rate of
scrolling in two dimensions.  The mouse may be dedicated in function
to performing this scrolling function or may be used to perform a
number of other selectable functions.  The total function of the
mouse or the method of selecting that the mouse is in "scrolling
mode" is not relevant to to this invention.

      The direction and rate or distance of the scrolling operation
is determined by the direction and distance of the mouse-controlled
cursor from a reference point on the screen.  A "natural" and always
present reference point is the geometric center of the screen which
may optionally be displayed by a cross bar or other indicator
whenever the mouse is placed in "scrolling mode".  Alternatively,
another implementation may utilize reference points which are
selectable by allowing the user to choose a particular coordinate by
using the mouse and using this coordinate as the reference point.

      To perform a scrolling operation the mouse is used to move the
cursor a particular direction and distance from the reference point
and the mouse is "clicked" to initiate the scroll operation.  This
direction from the reference point will be the direction of the
scroll operation.  The distance from the reference will determine the
total distance of the scroll operat...
