Polar Coordinate Laser Gun Mouse Manually Adjustable Selection Probe

      A methodology is described which enhances using a computer
desktop interface, specifically for pointing to objects on a desktop.
The methodology disclosed herein is a feature made available for a
polar coordinate laser gun mouse.

      Currently, mouse cursors are controlled by moving the cursor
around within a cartesian coordinate system.  The mouse cursor must
encounter an object in order to act on it.  This method forces users
to move the mouse cursor to the objects which the user wishes to act
upon.  A method which reduces user interaction, enriches desktop
object manipulation and makes interfaces more useable is desirable.

      This article describes new mouse operation based on the notion
of a polar coordinate laser gun mouse which uses a polar coordinate
system for pointer 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
mouse pointer is viewed as a laser gun capable of affecting objects
it points to but does not lie over.

      This article describes an object pointing feature when using a
polar coordinate laser gun mouse.  The feature is called a manually
adjustable selection probe (MASP).  The MASP e...
