Clipping of a Remote Pointer

       Disclosed is a scheme of displaying a remote pointer in a
remote shared window when the point of the shared window that the
remote pointer should point to is hidden.

      Multimedia desktop conferencing systems that have shared
windows use a telepointing tool to point to an object in a shared
window.  A pointer that is displayed in a remote shared window is
called a remote pointer.  When a pointer is in a shared window, its
corresponding remote pointer is displayed in a corresponding shared
window.

      Because each user changes the size of a shared window, the size
of shared windows is different among machines.  In addition, the
layout of windows in a screen is different among machines.
Therefore, a point where a remote pointer should point is sometimes
hidden because of the difference of the size of shared windows (Fig.
1) or because of the difference of the layout of windows (Fig. 2).
The scheme displays a remote pointer at the edge of the corresponding
shared window in a different state in order to tell the user that the
remote pointer is hidden.  When the user enlarges the size of the
shared window, the remote pointer is displayed in a normal state.

      A module for implementing telepointing exchanges the
coordinates of a pointer periodically or when a pointer moves.  To
detect pointer hiding, the module keeps the current size of each
shared window in a machine.  When the size of the shared window is
too...
