Can I use my mobile device (tablet or mobile phone) to participate?

• Yes. Big Blue Button is a web application that works in most current web browsers.
• Also for mobile devices, we recommend the usage of a headset!
• ATTENTION: please consider the increased data rate for a mobile connection (3G/4G/5G)! If you participate in multiple sessions, your data volume may not be sufficient until the end of the month.
• ATTENTION: functionality is limited on Safari.
• For iPads, Safari is the browser recommended by BBB.
• On iPads, Safari is working reliably, while using Firefox may lead to problems. To have a better performance, it is recommended to open the options menu in the conference at the top right and deactivate web cams (“Options” → “Settings” → “Data savings” → untoggle “Enable webcams”). Otherwise, more than 8-10 webcams can lead to a crash.

My Laptop has a microphone and speakers. It that sufficient?

• For listing only: yes.
• For active participation: no.
• The built in components of a laptop typically produce feedback (loud sharp noise) and echo effects. Built in microphones also transmit keyboard presses and touches on the laptop case.
• Online sessions require polite considerateness. Should you continuously produce sounds or disturb others, you have to expect that a moderator may mute you or even remove you from a session.
• Such problems do not occur when using a headset. Also more simple headphones as they are often included when purchasing a mobile phone should be sufficient.

Do I require a webcam?

• This depends on the type of course (lecture, seminar, tutorial, …) and on the moderators / lecturers. Please ask them.

I have received a link. What am I supposed to do?

• Login with your credentials (email address and corresponding password) on Video Conferencing
• Click the link or copy it into the address bar of your browser (Firefox, Chrome, Safari, Vivaldi).
• If necessary, enter the passcode that should be provided to you with the link.
• Your name (to change the name, see “The displayed name is my account name”) will be displayed automatically. If this is not the case, enter your name.
• Click on “Join”.
• Chose how you want to participate in the session, “microphone” or “listen only”. We recommend that you always chose the microphone, since changing this later is a little cumbersome. In case that you do not intend to speak directly, you can mute yourself after joining.
• Should you have chosen “microphone”, a echo test will follow, that tests the functionality of microphone and speakers/headphones. This process may need a couple of seconds.

I have clicked on “listen only” and now I cannot participate in the session

• Click on the headset symbol and leave the audio session.
• Then press on the now displayed crossed out telephone handset.
• Choose “microphone” to join the session with your microphone. Now you can participate in the session.

Can I change the language?

Click on the three dots in the top right corner (Options). Click on “Settings”. Here you can choose the application language.
