Your poster and the respective uploaded video from you are visible from Monday, December 13, 2021 until January 31, 2022.

Preparation of your presentation

Poster presentation

Please create your poster presentation as a pdf document as usual. The presentation itself must be in English. Your poster should meet the following criteria for presentation:


16:9 ratio (669 mm x 1189 mm), landscape, 1 page


maximum 150 MB

File format:


Slide presentation

Please prepare your Poster as a PowerPoint slide (approx. 4-5 slides). These slides are the basis of your video presentation in the next step. Your PowerPoint presentation should be prepared in 16:9 aspect ratio. Additionally, the PowerPoint file is very handy for live discussions.

Video presentation

Since we are running a virtual conference this year, all poster presenters are required to make use of electronic presentations and to provide a video presentation of their poster. Please record your created slide presentation as a video in advance of the event. Your pre-recorded and provided presentation will offer attendees the possibility of previewing your work. 

You should record your presentation with sound and if possible, a picture-in-picture inset of you speaking. This is an excellent opportunity to make the presentation more personal and attractive for the participants. You may use virtual laser pointers or highlight text passages to draw attention to certain areas of your slide while you speak. Each video presentation should not be longer than 5 min. Please prepare your presentation accordingly to strictly adhere to these time limits. Presentations longer than this limit will be truncated.

Your produced video should meet the following criteria:


1920 x 1080 pixels (Full HD, 1080p)


500 MB (max.)

File format:



5 minutes (max.)



Recording your presentation with PowerPoint (Windows)

PowerPoint already provides suitable tools for recording. You can find instructions on how to proceed with recording divided by the PowerPoint version you are using (Office 365, 2010, 2013 – 2019, macOS) at the following link:

Record a slide show with narration and slide timings


Once you have added an audio track to your presentation, export your presentation as an mp4 video file as described in the following links:

Turn your presentation into a video – When exporting, select the “Presentation quality” option 1920×1080 pixels (Full HD, 1080p)

Recording your presentation with Keynote (macOS)

If you use Keynote as a presentation program, you can find instructions on how to record your presentation with Keynote (MacOS) behind the following link:

Record Keynote presentations on Mac

Follow the link below and you will learn how to export your recorded Keynote presentation to a mp4 video file: Export as *.mp4 files under macOS

Alternative recording option

As an alternative to the PowerPoint on-board tools, or in case you use a program other than PowerPoint to produce your presentations, you can also use freely available add-on programs such as OBS (Open Broadcaster Software) to create your video presentation. These are very intuitive to use and also produce high quality presentation videos (Download Link OBS Software).

For this purpose, we recommend a video tutorial that explains how to perform a screen capture including webcam on your device with OBS.

Submission of your poster presentations (poster & video)

The deadline for the upload of your presentations is December 10, 2021 (EST)

Please submit your poster presentation together with your video presentation electronically.
Please log in to the Conference System with the data used when submitting your contribution at Link to Conference System. The upload for poster and video presentations will be activated from November 28, 2021.

After you have logged in successfully, the “Upload” link in the menu bar will take you to the upload form of your contribution. The upload itself is self-explanatory. If you want to change an already uploaded file, please repeat the upload with a more recent file version. The newer file replaces the existing version. If the upload fails for whatever reason, please send us your file(s) via WeTransfer ( ). In doing so, address/send your transfer to  and leave a note in the comments field with your name, email address and title of your contribution so that we can match your presentation(s).  

Posters have the same value as an oral presentation and must be uploaded as a PDF to the online system in addition to a 5-minute video. During and after the conference, attendees can view your poster/video in the password protected area (not visible to the public without a password). This gives the opportunity for an attendee to plan and even look at your poster after the conference and contact you if needed with comments and questions.

The day of your live presentation

You will receive your access data to the virtual conference platform by e-mail a few days before the conference starts. The poster sessions will be held in the virtual poster area as live events. Your poster presentation will have a virtual room available where you can meet interested attendees who want to get into a discussion with you. Up to 50 attendees can enter your room with video/audio active.
Presenting authors are expected to be present at their poster during their entire session to talk about their work to the audience and answer questions as appropriate. We kindly ask you to log in to the virtual conference and join your poster room at least 10 minutes before the start of your session.
Please navigate to “My live sessions ” within the left side menu, click on the poster session, click on your poster and press the button “Click to join the room” to enter your presentation room. As soon as you entered your private meeting room on your poster the label “Live” will be activated so everyone can see that you are available in your room. Share your screen so that you can zoom in and out for explanations and use the laser pointer, e.g., from PowerPoint to show explicit areas you want to point out. Attendees will receive access to your room 5 minutes before your poster session starts officially.
