event or whenever the user changes the position of the mouse
while holding down the mouse button. In this way, the user can
hold the mouse button down and move the pointer icon around in
his or her display window (figure 5) and information packets will
be sent over the network only as needed. Figure 10 is a
representation of the data fields comprising a conference
participant table in which is stored conference participant
information received from information packets. When a
workstation receives updated mouse computer event information,
the table of figure 10 is updated (col. 7, lines 1-21). Thus,
the table contains sufficient information to redraw the pointers,
arrowheads and connecting lines. If the mouse computer event
information is a mouse button-up event, the table is cleared by
deleting any existing coordinates and replacing them with a blank
or null entry (col. 7, lines 22-31). In the event the table
entry for the pointer icon position is blank, no arrowhead or
connecting line is drawn for that user. Updating and refreshing
of the displays with new computer event information provides the
illusion of dynamic movement of the pointer arrow (col. 7, lines
39-45).
Figure 11 illustrates the steps followed when a participant
uses their workstation to point to a data object in the work area
