In the following we include the printout of the hyper-media documents that were used within NCSA Mosaic for the presentation. The document was shown on a set of computer-screens and the different pages were accessed via links that are indicated in the text by bold-italic expressions: When the presenter referred to that expression, the local operator would point and click at this link, thereby displaying the new page on the screens.
The original script was to start the presentation by playing a sound-file
of birds from Zimbabwe
and then enter with the text:
I am not calling from Zimbabwe but from Urbana/Illinois, but there
is no reason why I could not have called from Africa.
Within the shortness of time for preparation, it was not possible to
integrate the computers in the local sound system but in future presentations
the inclusion of sound files in the presentation might help reduce the
actual realtime phone-connection. We also planned to
end the presentation with the same sound file as an invitation to explore the
Internet directly and interactively on the different workstations in the
presentation room, to indicate that this form of presentation does not have to
be one-way but represents a seamless integration into an interactive
electronic discussion.
Instead of discussion via phone, this could also happen within the
Mosaic/WWW context by linking sound (or even video) sequences into the
document.
If we assume that we use telefone-quality sound per min, with inexpensive modems
we could transfer about
to transmit
of sound. Typical internet connections today vary around
per second, which makes transmission of sound files feasible.
To Illustrate this point we have included a soundfile in the
electronic version of this document . For low speed connections it also
would be possible to use analog telefone lines for the aural transmission of
the presentation text prior to the conference.At the conference site, the recorded
presentation can be incorporated into the hypertext document
according to the insructions of the presenter.
All of these cludges will not be neccessary, when we have a truly global
connection.
The quasi-realtime feature of this procedure is of great advantage compared
to the network demands of any types of real realtime multi-media tele-conference
alternatives.
In the following we present the different pages as subsections.
