Abstract

Disclosed is a method for telepointing in real-time teleconferencing systems. This method allows users to leave footprints in an electric document that is shared in a teleconferencing system. It involves a computer system, a (shared) document, a (tele)pointer, and a pointing device such as a mouse. The computer system displays the document on the screen, and displays the pointer on the document. A user moves the pointer by means of the pointing device, and issues a command to the computer system by performing an operation such as clicking a mouse button. The computer system receives the command and displays a copy of the pointer (i.e., a footprint) at the position where the pointer was displayed. By repeating the operation, the user can leave two or more footprints.

Footprint Telepointer

   Disclosed is a method for telepointing in real-time
teleconferencing systems.  This method allows users to leave
footprints in an electric document that is shared in a
teleconferencing system.  It involves a computer system, a (shared)
document, a (tele)pointer, and a pointing device such as a mouse.
The computer system displays the document on the screen, and displays
the pointer on the document.  A user moves the pointer by means of
the pointing device, and issues a command to the computer system by
performing an operation such as clicking a mouse button.  The
computer system receives the command and displays a copy of the
pointer (i.e., a footprint) at the position where the pointer was
displayed.  By repeating the operation, the user can leave two or
more footprints.

   When the pointer is arrow-shaped or has oblique
orientation, the user can change the orientation by means of a
technique such as that described in JP8-1998-0375, "A Method for
Changing the Direction of a Pointer Depending on the Motion."  The
computer system can change the color of each footprint according to
the "moth metaphor": The colors are determined by the time or the
order in which footprints were left, with older footprints having
darker colors.  Figure 1 shows an example that uses an
orientation-controlling method and the moth metaphor.  The computer
system can also indicate the order by displaying a line that connects
all the footprints.

   The computer system can provide a searching function that
allows the user to jump to a particular part of a document, or a
page where a footprint exists.  It can also allow the user to erase
footprints by means of a pointing device operation such as clicking
another mouse button, and can erase some footprints itself, if more
than a threshold time has passed since they were created, or if more
than a thre...
