Speakers & authors

If you're presenting

Lectures, posters, and what to bring or upload — on-site and online.

I'm presenting on-site — what should I bring?

Check the presentation guidelines first, as they include information on slide format and timing. Upload your presentation via your user account well in advance. After uploading your slides, you can immediately check the layout as well as the playback of embedded videos and animations.

We will transfer the uploaded presentations to the presentation laptop at the venue. On site, presentations must be given using the venue equipment. The use of personal laptops is not possible.

I'm presenting online — anything I should know?

Start with the presentation guidelines. You don't need to upload your slides in advance — just join via the platform and Zoom on the day of your presentation. If your connection might be shaky, send us a pre-recorded video as backup. 

The Zoom desktop client runs more smoothly than the browser version.

How does the hybrid poster session work on-site?

Please print your poster in A0 portrait format and mount it on the poster wall assigned to your contribution on site. Physical posters will remain displayed throughout the entire event. Mounting materials will be provided at the venue.

All poster authors must also upload a digital version of their poster via the submission management system. The digital poster will be displayed on the event platform for online attendees and will support live exchange between the on-site and online audiences.

Why upload my poster digitally if I'm there in person?

So online participants can see your work too — and so everyone, in the room and remote, can discuss the poster.

Session chairs

If you're chairing a session

Running a hybrid room — equipment, timing, audience questions, and the little gotchas.

When should I arrive in the lecture hall?

Please be in the room during the break before your session and check in with our technical staff — they'll get you set up.

Will I get a tech briefing?

Yes. Our on-site tech team will walk you through the equipment during the break right before your session.

What equipment will I have at the chair desk?

A laptop or tablet — for following the online stream and chat — and a microphone, in every lecture room.

Can I cut in via the microphone during a talk?

Yes — toggle the mic with the button on the unit itself. Your audio goes straight to the room and the online stream.

Can both online and on-site participants ask questions?

Yes, both audiences contribute. As chair, try to alternate between the room and the chat so each side gets airtime.

Why should I follow the online stream on my laptop?

The laptop shows the live stream and the chat — that's where you'll spot online raised hands and incoming questions to read aloud or relay to the speaker.

Anything to watch for with audience questions on-site?

On-site questioners must speak into the roving microphone our tech staff hand around — without it, online viewers won't hear the question.

If a question is not asked into a microphone, session chairs should repeat the question into the microphone before the speaker answers it, so that online participants can also hear the question.

How do I avoid noise from my own setup?

If you have a mobile device with you, please switch it to airplane mode before the session to avoid interference with your microphone.

What about noise from online participants?

Our tech team handles it. If a stray microphone causes feedback during a talk or Q&A, they'll mute it from the production side.

How do I know if a talk is on-site or online?

You'll receive a session list ahead of time marking which talks are in person and which are remote.

How are plenary speakers introduced?

A handout with CV and abstract is provided for each plenary speaker — use it for the introduction.

How do I keep the speaker on time?

Watch the clock and intervene as needed. Remember: online speakers can't see the room, so they may need an audible cue — a "two minutes left" rather than a held-up card.

Still stuck?
