There are three kinds of rooms: virtual, hybrid, and quiet rooms.

• The virtual rooms run exclusively on Zoom (see the virtual area). All the sessions in virtual rooms are fully online, that is, all the participants (speakers, chairs and attendees) are online.
• The hybrid rooms run hybrid and in-person sessions. Since all the sessions will be streamed, they are associated with both physical and virtual rooms. Exceptionally, hybrid rooms can be used for fully virtual sessions. This is indicated in the programme by adding "(virtual)" after the session's title.
• The quiet rooms can be used by the in-person attendees to participate in virtual sessions with their laptops and headphones.
