Methodology for Marking Objects using a Polar Coordinate Point and Shoot Cursor

       A methodology is described for marking a group of desktop
objects using a polar coordinate point and shoot cursor.

      This article defines new mouse operation which allows an easier
and more useable method of desktop manipulation.  It is based on the
notion of a polar coordinate point and shoot cursor which uses a
polar coordinate system for pointer rotatable direction and
selection, while using the standard Cartesian coordinate system for
positioning the mouse cursor.  A mouse cursor is implemented which
can traditionally be shaped as current mouse cursors, but is
rotatable to facilitate pointing.  It also allows pointing to be
enabled without touching the object.

      The present article offers convenient multiple object selection
through a sweeping motion of a probe line segment which emits from
the point and shoot cursor pointer, called a manually adjustable
selection probe (MASP).  The MASP extends from the mouse cursor for a
user-defined length in the desktop path line.  The MASP is a vector
parallel to the mouse cursor rotating pointer angle and emits from
the mouse cursor pointing tip.  The vector displays as a line on the
desktop between the mouse cursor and the end point which is adjusted
by the user.  A unique mouse button press sequence, keyboard
entering, voice activation, etc., can be used to extend or retract
the MASP.  The MASP vector length will...
