Smartest AG Room in the world??? Was: [AG-TECH] Electronic Whiteboards (fwd)

We have not yet done alot with integrating the touch screen supported
software into the AG yet. Our plans include experimenting with Bridgit,
which is the Smart Technologies collaborative software, but we haven't
gotten to it yet. We have one piece of collaboration software that
already makes use of Bridgit and we are going to look at integrating it
as a tool in AG. Depending on student resources we hope to get to this
in the new year.
In our "Smart" AG room we currently use a combination of VNC, computer
video scan conversion, and camera based video feeds of the screens to
share the SmartBoard environments. Each of these approaches have their
uses... We haven't yet done a lot of rigorous testing of this from an
HCI perspective, but this is planned over the next year...
