Connect with an e-structor Now (Live Tutoring on an Interactive Whiteboard)
  • The "connect with an e-structor now” icon enables you to work one-on-one with an e-structor (tutor) in a live tutorial session (note: you may have to wait just a few minutes if another student is working with a tutor)
  • Live tutoring available in all supported programs.

Here is an excerpt of a student’s essay feedback. An e-structor will make comments at the top of the page and also throughout the document.

it’s also simple to start a WebRTC live video interaction with your instructor or any other student, just make up a name for a classroom, type it in and click start chat. Tell the other person to do the same and you’re all set.

As always make sure you’re giving this a try in Firefox Nightly or the latest stable build of Google Chrome. If you are on a tablet make sure you are on Google Chrome beta if you are using the Google Chrome browser.

Something else to note is that for the one on one video interaction is limited to just two participants per a room. If a room name is occupied by two people the third person who tries to connect to this room simply won’t be able to connect.


A quick note about this step: "Once remote media starts streaming stop adding ICE candidates” – this is a temporary solution which might result in suboptimal media routing for many network topologies. It should only be used until Chrome’s ICE support is fixed.

Peer Connection capability in Google Chrome

While working with the new PeerConnection capability in Chrome we discovered a strict order of operation for it to work; more specifically:

  • Peers must be present with local streaming video before sending SIP (offer/answer SDP)
  • For ‘Answerer’; Do not add ICE candidate until the peer generates the ‘Answer SDP’
  • Once remote media starts streaming stop adding ICE candidates
  • Never create peer connect for answerer until you get the ‘Offer SDP’

We fixed it by handling those issues and handling the connection in the order described above. This was crucial to making the connection work flawlessly. Before we did that it would work only every once in a while.
