The information has been structured
now how can the telegroup access it for instant use?
Web pages are usually thought of as static displays.
So how can the Web be used to deliver meeting
maps in real
The answer is to think of the Web as another live networked visual medium, like television, only with higher resolution text and graphics and a lower refresh rate.
All visual displays (of scanned images, text and graphics) are static between refreshes! The only difference is the length of time between refreshes, and what the viewer has to do to cause the image updating (nothing for TV, manual intervention* for the others).
Consider these different visual media and how often the image contents can be "refreshed" or changed:
display refresh rate Telephone book once every year TV Guide magazine once every week Newspaper once every day Web page once every 30 seconds Television image once every 30th of a second
If the telefacilitator is writing a new version of the Web page to the net every minute or so, then members of the telegroup can update their images simply by hitting the "RELOAD" button in their Web viewing application. The Web thus becomes a source for refresh on-demand text-graphics.
* Automatic refreshing is possible thanks to a Web technology
called "server side push." Under this scheme, whenever the
content of the Web page changes, a new version is "pushed" to
each browser tuned into that page. This results in automatic
refreshing and increased convenience for the members of the
