Abstract

Disclosed is a method to provide a continuously variable relationship between the orientation of the ball mechanism and the outer shell of a "mouse". This provides a variable rotation between the physical X-Y movement of the mouse and the apparent X-Y movement of the mouse pointer on the users computer display.

Skewed Mouse Control Device

      Disclosed is a method to provide a continuously variable
relationship between the orientation of the ball mechanism and the
outer shell of a "mouse".  This provides a variable rotation between
the physical X-Y movement of the mouse and the apparent X-Y movement
of the mouse pointer on the users computer display.

Several possible implementations are proposed:
  1.  Hardware - thumb wheel
        Essentially divide the mouse mechanism into two parts.
       One part is the "ball" mechanism and the other part is
       the shell held by the user.  The two parts are obviously
       connected but not rigidly.  It is possible to have a
       continuously variable relationship between the orientation
       of the ball mechanism and the outer shell.
        For implementation, this might be done by having the
       mouse ball and its transponder mechanism mounted on a
       circular platform.  The diameter of this platform is
       just slightly larger than the width of the mouse
       shell.  This circular platform might have a raised or
       serrated edge, much like a coin.  The mouse shell would
       essentially sit on this platform.  The operator could
       change the orientation of the ball mechanism by using
       his/her thumb to physically rotate the inner mechanism
       with respect to the outer shell.
  2.  Hardware - skew bar - 1
        This method also divides the mouse mechanism into two
       parts similar to the method described above.
        Add a "skew bar" control to the mouse.  This skew bar
       would be another user-operated control on the body of
       the mouse.  Internally, the mouse ball and transponder
       mechanism would be mounted on a circular platform.  Each
       time one end of the skew bar was depressed a mechanical
       pawl would engage a ratchet on the platform holding the
       mouse ball and transponder, and this platform would
       advance (rotate) one "increment", perhaps five degrees.
       This obviously has the effect of rotating the perceived
       x-y movement axis with respect to the physical position
       of the mouse.  Depressing the opposite end of the skew
