You will be able to join all hybrid and virtual sessions through the congress website after logging in to the User zone. Virtual sessions, submission forms (for submitting PowerPoint presentations, pre-recorded talks and e-posters), and registration for the congress are accessible through the User zone using the same username and password. Once you have created a user account in the User zone, your login credentials remain the same. You will not receive any join links by email.
The oral sessions will be live. All presenters will give live talks during the congress.
- Remote presenters will run PowerPoint presentation on their own computer and will share their screen via Zoom.
- The congress organizers will run the face-to-face presenters‘ presentations on computers in the rooms at the congress venue.

Each paper should have maximally 15 minutes (10 minutes of the presentation + 5 minutes of a discussion).

Online (remote) presenters will run PowerPoint presentation on their own computer and will share their screen via Zoom.
Face-to-face presenters: The congress organizers will run their presentations on computers in the rooms at the congress venue. Presenters will be able to control the presentation using a remote control (clicker).

Both online (remote) and face-to-face presenters are required to submit their PowerPoint presentation before the congress. Please keep in mind that PowerPoint presentations submitted by remote presenters and PowerPoint presentations submitted by face-to-face presenters will be used in different ways:
- Online presenters: The submitted presentation will serve as a backup and will only be used if presenters are not able to share their presentation via Zoom due to unexpected technical issues. Presenters are expected to run their PowerPoint presentation on their own computer and to share their screen via Zoom.
- Face-to-face presenters: The congress organizers will upload their presentations to computers in the rooms in the congress venue.

We strongly recommend to download the Zoom desktop client and to install it on your computer. It is also possible to join the Zoom webinar from your Internet browser using the web client. The Zoom web client allows joining a Zoom meeting or webinar without downloading any plugins or software. However, the web client has limited features and should only be used if you can't access the other options.
We strongly recommend to download and install the Zoom desktop client and to familiarize yourself with Zoom in advance before the start of the congress.
