Information for speakers

All talks of the conference will be livestreamed online to allow remote attendance. Each session will also be recorded. By the end of each day, the recording of the sessions will be made accessible to all registered participants. At a later time after the conference, the recording will be edited and posted online. A privacy statement with more details will be sent to all speakers and participants.

We highly encourage all presentations to be in 16:9 format in order to make the best use of the projectors in the conference room.

Unless otherwise indicated in the program schedule, invited talks are 25 minutes total (20 minutes for the presentation and 5 minute for questions. Contributed talks are 15 minutes  (12 minutes for the presentation and 3 minutes for questions).

Information for in-person speakers

Only the conference room computer will be used to display the presentations. In-person speakers will need to upload their talks to the computer in the conference room before their talk. Supported formats are PDF, Powerpoint (pptx), and Keynote.

Information for online speakers

Participants with an online oral contribution will receive a Zoom link the day of their talk, to which they should connect 10 minutes before the scheduled time of their talk. The Zoom meeting will be used as a virtual studio, in which the IT team of the venue, and a member of the LOC will be present. The conference room will also be connected to this Zoom meeting via multiple cameras located in the room. The online speakers will give their talks by sharing their screen within this Zoom meeting. Once the online talk starts, the IT team will display the shared screen and the camera stream of the speaker in the conference room and on the online livestream. The online speakers will also be able to see, hear and answer the questions from the room within this Zoom meeting.

We highly encourage online speakers to make use of headphones with integrated microphones in order to ensure a good audio quality.
