Big Blue Button Open Source Project Vision

"Our vision is that starting a web conference should be as easy as clicking a single metaphorical big blue button. As an open source project, we believe it should be easy for others to embrace and extend education. And while web conferencing means many things to many people — our focus is to make the best web conferencing system for distance education."

Presentation - Instructors can upload any PDF presentation or office document and keep everyone in sync with their current page, zoom, pan, and the presenter’s mouse pointer.

Tips for Successful Big Blue Button Meetings

For the instructor/moderator:

  • If possible use a microphone/headset.
  • Click the "Mute All" icon in the lower left corner of the "Listener" window to eliminate audio feedback. Ask users to click the "Raise Hand" icon in the lower right corner of the Users window. Then you can selectively unmute them so they can talk.
  • Alternatively you could selectively mute each user to see if the problem goes away.
  • In the worst case where someone is not hearing the meeting, the chat window is always there.

For students:

  • If possible use a microphone/headset or earbuds.
  • In the "Listener" window, click the speaker icon to the left of their name to mute their audio when not speaking.

For both instructor/moderator and students:

  • Since this is a Flash application, you can right click on the window to get to the flash settings.
  • For the Microphone settings tab, check the "Reduce Echo" box and "Close" the settings.
