We recently polled staff and research students in the School on some approaches and suggested technologies for moving forward with better and more integrated support for Video Conferencing in the School: https://wiki.inf.ed.ac.uk/DICE/VideoConferencing. That page has now been updated with a summary of all the comments received.
The proposal now is that meeting room 5.02 in the Forum will be kitted out with generic hardware (dual monitors, camera, audio system with remote microphone pod and a computer) and made available for anyone to use. We will make at least Zoom available, and one or maybe two other systems, in this room and on School desktops. Everyone can then try these out for a while, alongside the existing Lifesize facility in 4.02.
