Abstract

Disclosed is a system which enables a personal computer user to select one of several graphics objects displayed on a computer screen, even if they overlap each other, by 1) picking any part of the object with a pointing device (such as a mouse), 2) showing some candidates on the display simultaneously and separately, and then 3) picking the final object from these candidates. The method of showing candidates simultaneously and separately, which is used in this invention, involves much less work in selecting the final object than the method of showing candidates sequentially, which is used in other inventions.

Graphics Object Selection System

      Disclosed is a system which enables a personal computer
user to select one of several graphics objects displayed on a
computer screen, even if they overlap each other, by 1) picking any
part of the object with a pointing device (such as a mouse), 2)
showing some candidates on the display simultaneously and separately,
and then 3) picking the final object from these candidates. The
method of showing candidates simultaneously and separately, which is
used in this invention, involves much less work in selecting the
final object than the method of showing candidates sequentially,
which is used in other inventions.

      Ideas for selecting a graphics object from overlapped objects
by "the method of showing candidates sequentially" appeared in
Japanese published unexamined patent applications 60-214034,
62-264375, and 63-14229. The "method of showing candidates
simultaneously and separately" of this invention is a unique way of
selecting an overlapped object and is much simpler than the methods
of showing candidates sequentially that are adopted in the
above-mentioned patent applications. There is a highly visual and
consistent user interface for selecting graphic objects.

      In order to select a segment, a user put a mouse cursor in the
selection-effective-area of this segment and click the mouse button
(Fig. 1).  If three segments ((a), (b), and (c)) overlap each other
on the display (Fig. 2), the selection-effective-are...
