A completely digital defence is conducted as a Zoom webinar. This means that only invited participants (panelists) will be able to show video, control their own microphone and share a screen. Everyone else will only be able to watch and listen, and can be granted permission to turn on their microphone if they should ask for it. The webinar will be set up and controlled by a defence technician.
By sharing their screen the candidate can show slides and present their work to the opponents and anyone else following the defence.
The defence will still follow regular procedure as far as possible. It will therefore be open to the public, and anyone who wishes to ask questions can do so ex auditorio when invited to do so by the chair of the defence after the opponents have finished asking their questions.
