Abstract

In desktop conferencing systems (such as P2P) shared 'whiteboards' or 'chalkboards' are often provided. These provide a shared graphic workspace in which graphical objects may be viewed, edited, reviewed and annotated.

Annotation Facility for Desktop Conferencing

      In desktop conferencing systems (such as P2P) shared
'whiteboards' or 'chalkboards' are often provided.  These provide a
shared graphic workspace in which graphical objects may be viewed,
edited, reviewed and annotated.

      In most modern systems, annotation can be by textual overlay or
by freehand drawing using a mouse or stylus.

      Textual overlay has the disadvantage of being slow for the
non-typist, and free hand drawing has the disadvantage of being slow,
and often illegible.  Certainly the results can look
'non-professional', and the speed factor can interrupt the flow of an
otherwise creative information exchange.

      The solution described below provides a predefined set of
common annotations in an easy to access way.  Typically this might be
by means of a floating "button-bar", "ribbon" or "tool-bar".

      Each annotation is scalable and positioned on the shared
workspace and stretched to size.  The size aspect allows the
annotater to indicate varying degrees of the meaning of the
annotation, i.e., a large 'tick' is clearly better than a small one.

      An example set of everyday general purpose annotations might
include 'tick, 'cross', 'OK', 'Yes', 'No', 'sp?', various arrows,
forms of typographical markup (as used by copy reviewers, etc.).

      For certain types of users a customization feature will be
required to provide additional annotations.
