The Videoconferencing Equipment at UoM
The general classroom set up inside the videoconference
suite is mostly suited for tutorial groups of not more than
10-15 students per group.
The general layout is that of a semi-circular seating
arrangement with the camera and monitor facing the
audience. A document camera with accompanying
monitor and presentation screen are also at the front so
that the audience can follow what the tutor is presenting
more accurately.

presentation saved on the laptop or
the workstation or a presentation from
the remote end. This screen can be
