Here you will find instructions on how to join a session that is currently in progress. The minimal requirement is the ability to use Zoom. If you are willing to participate, have registered, and did not receive a Zoom link, please email



Poster sessions are based on two platforms: VCC and Mozilla Hubs, that complement each other. Plus, Zoom is used during live VCC sessions for audio connections. In comparison to Mozilla Hubs, VCC offers more functionality: e.g., it includes Virtual Actors - poster presenter bots.

Mozilla Hubs supports local voice chat and runs in any browser and also in VR, while VCC requires a Windows machine with a non-integrated video card.

Plenary talks are based on Zoom and VCC. Speakers give Zoom presentations that are streamed to VCC and back to Zoom, therefore, Zoom-only participation is possible.


Step-by-Step Instructions

1. Install and run Virtual Convention Center (VCC)

To do this, you need a Windows computer with a videocard of at least 1GB VRAM (integrated videocards and Macs do not work). Those who cannot meet these requirements should skip to Step 3 and use Mozilla Hubs and Zoom only.

To download and start VCC on a Windows machine with a non-integrated videocard, please use this link (the link may be updated frequently, updated on Nov 12, 11:40 UTC):

Tick the checkbox, download and launch the Improbable Launcher. You will be guided further. In case of errors due to missing dependencies, to install DirectX on Windows, use this link: Finally, select "Play".

If you need launcher installation guidance, use this link:

After installation, video instructions on how to use VCC can be found here:
