Thank you for your contribution as a chairperson during the ISB 2021 virtual Congress, below you find some practical information regarding the sessions.

All Oral abstracts will be presented in parallel 60 minutes sessions with 5 presenters in each session. Each session will be led by a chairperson. For detailed program, please visit the website;

Oral presentations are to be a maximum of 10 minutes, followed by 2 minutes of discussion.

You as a chairperson are asked to rigorously enforce the schedule, i.e., to strictly limit the length of the presentations.

Practical information about the platform/session

Presenting authors and session chairs will present and participate Live via Zoom for each session.

The viewers, on the other hand, will watch the congress via the digital congress platform OnAIR, where they also have the opportunity to ask questions via the chat function. Viewers will not be seen with image or sound  – only the presenting authors and the chairperson.

How do I participate as a chairperson?

  • Shut down all other programs (except OnAIR) on your computer and keep only Zoom running
  • Log in to the zoom link 15 minutes before the session starts (the link will be sent to you via email on July 25th)
  • The technicians will be in the virtual studio and talk to you via zoom when you check in
  • You will participate with video and audio
  • You will also need to be logged into the OnAIR platform, choose the session in the agenda that you are chairing to view the questions from the viewers, which you will see on the right-hand side in the platform.
  • If possible we recommend you to use two screens, one for the zoom meeting and one for the OnAIR platform where you can read the questions from viewers in the OnAIR chat function (please do NOT forget to mute the sound from the platform)

Things to think about

  • Make sure you sit in a quiet place with good light so that you are visible without shadows or anything else that disturbs. Keep the light towards you, not from behind
  • Feel free to use a microphone other than the one built into your computer, such as a mobile headset
  • Technicians will match sound, light and image with you before you are posted live
  • When you are LIVE – Talk into the camera on the computer – then it will be the best experience for those who watch
  • Do not drink coffee/eat food during the session

How do the viewers ask questions?

  • Viewers ask written questions via the congress platform OnAIR
  • The chairperson should read the questions and selects those that presenting authors can answer if there is time after each presentation. Note that there is approximately an 18-second delay between the zoom session and its broadcasting on OnAIR.

Technical instructions

You will on the 25th of July get an email with a Zoom link for you to connect to when chairing your session/s. The link is personal so do not share it with anyone. The session will be live, and you need to use both camera and sound from your own computer.

We want you to connect 15 minutes before your session starts so that we can make sure that everything works according to plan. This will also give you time to meet the presenting authors before the session.

Things for you to prepare at home before attending

  • Good light pointing towards your face, lamp or natural light from a window.
  • Raise your webcam. Put some books under your laptop or use a laptop stand so that the camera is straight in front of you or slightly above.
  • Use a headset with a microphone to prevent unwanted noise.
  • Have a good internet connection.

If you feel the need to test run your technical set up, you can book an appointment by emailing You will then be contacted by our technician who will set up an appointment for your test. The tests ill be held the 15th and 16th of July between 9.00 and 16.00 CEST.
