CONGRESS & TRADE FAIR will be exclusively digital this year. For your participation at CONGRESS, the TRADE FAIR-FORUMS and for the exchange with exhibitors you need the free video conference system alfaview.

How can I install or test alfaview?

The software can be installed without administrator rights on any modern computer running Microsoft Windows, Apple macOS and Linux. Alfaview is available free of charge for Windows, Mac OS X or Linux and in the AppStore.

  1. Download alfaview and start the installation.
  2. After you have installed the software, please enter this room to test the function.
    The following window will open now in your browser:


  3. Enter your name and click on enter room..
  4. Accept the terms and conditions of alfaview.
  5. The alfaview app will now open. Allow this.
  6. In the alfaview app you can see a preview of your camera image. Under "Set up audio devices" you can select your microphone and loudspeaker.
  7. You can now see yourself in the preview image through your camera in the alfaview app and and you should have no technical difficulties taking part in ARBEITSSCHUTZ AKTUELL Digital.

Digital video rooms like these will be used for the CONGRESS and FAIR-FORUMS lectures from 06.–08. October. You'll be also able to talk to exhibitors in person at the TRADE FAIR. As a participant in ARBEITSSCHUTZ AKTUELL Digital, you can therefore test all functions in advance in this test room and familiarise yourself with the system.

Functions alfaview:

An additional "transcription" function will be available for ARBEITSSCHUTZ AKTUELL Digital. We offer you a transcription of the spoken word. This is an application based on artificial intelligence.

As long as you are in a conference room, your name is visible in the participant list. You can post questions or comments in the chat. If possible, the moderator will take them into account in the discussion. You can also write the term "request to speak" in the chat, then the moderation can allow your question "live". Please note: you will need a camera and a microphone.

In the settings you have the possibility

  1. to select the bandwidth usage (e.g. with poor internet connection),
  2. control the volume and
  3. set your own voice activation level
  4. select the desired speaker, microphone and camera.
  5. Further details can be edited under "show all settings".


What technical requirements must be met?

To use all the functions of alfaview you need:

  • A computer or laptop with the operating system Windows 7 / newer, MacOS 10.12 / newer, or Linux For iPads, the alfaview app is available from the App Store.
  • Either a front camera integrated in the end device or an external webcam (available from approx. 20 €) to transmit the image.
  • A headset or headphones with microphone function for audio transmission (the integrated microphone of the terminal device can also be used, but using a headset is more pleasant for all participants - keyword feedback).
  • An undisturbed environment and at best a monochrome background will improve the image that the other participants see of you.
