Scanning view is fairly difficult to implement, and runs the risk of
inducing motion sickness in the remote audiences. Also there are a limited
number of cameras and camera angles available.

Actually, I believe the MAIN camera was always pointed at the screen
during your talk. Part of the time it was zoomed in on some part of the
screen in order to provide info for the sites taht were not getting
distributed powerpoint or web page views. For example, I know some sites
lost sync with the powerpoint, so I zoomed in on that for a while. Later,
I zoomed in on the web page in order to handle the sites that didn't
manage to get a copy of it up. The MAIN camera was not situated in a good
position to show much of anything except the main screen, so I know it was
pointed at it, but it probably wasn't very helpful to you at vic size.
Remember that you are looking at a full shot of a 20' wide screen in which
your powerpoint is only half the screen at most (much less than that if
you want both power point, netscape and your head shot up as well). With a
20' screen and 2 projectors, there is a severe limitation on available
screen real estate.
The lesson here is that some advance communication/rehearsal between
remote presenter and chautauqua site is very useful, to let the presenter
know where things are being shown and what he can do with them. I have
also noticed many problems with people being able to find the available
camera views from a given site in a hurry especially since if they get
seperated form one another during startup -- Better labeling might be in

The problem with this is that the display method we are using involves
using many different windows being put up on a single windows NT desktop.
If an application takes control of the whole screen, it takes control of
the "whole screen". This means that running VNC would eliminate the
ability to show netscape or any of the remote video feed on the main
screen at the same time. I completely agree that some better method of
running distributed powerpoint, especially one that handles animations and
movies is vitally needed. On the other hand, it is probably too late to
make many changes for the UKy chautauqua.
