I am trying to come up with a method to live broadcast my lectures to parties connected to the internet. Up to now, I have been using FaceTime to transmit my work on a whiteboard. This method works, but the quality is lacking.

The crux is I do not want to record "my person," but rather what I write on some surface. This previously asked question (Device for writing a lecture with a stylus for video lecture recording) solves the problem for non-live transmission. That is, for the previously answered question, the individual records and subsequently uploads the lecture. I would like to do something similar, but live-transmit the lecture. Does anyone have a reasonable method by which they do this?

My ideal solution would be something like an interactive pen display (e.g., http://www.monoprice.com/Product?c_id=113&cp_id=11314&cs_id=1131401&p_id=12076) which could somehow be transmitted in real-time. The software side of this is where I get iffy. (Also, I am running a mac.)

Another solution could surely come from a document camera, but again the software leaves me dry.

To summarize: I am looking for a hardware/mac-based software solution to live transmit document-based lectures over the internet.

    Could you share screen? How about a painting software + a pen tablet? – Penguin_Knight Mar 23 '15 at 13:50
  • I could certainly screen-share. That might be an efficient solution. – Jonathan Gray Mar 23 '15 at 16:09

You could try using a Bamboo tablet (or really any tablet - I mention Bamboo only because I've heard good things) with this service: AWW - A Web Whiteboard. The $10/month version allows you to invite view-only guests, as well as save a limited number of boards (they've got several levels of plans).

The advantage of the web-based solution is that it doesn't matter what OS your viewers have - they just need an internet connection.


If you have the time to prepare the lecture beforehand, subjecting your audience to your scribbling and correcting on-line isn't the best use of your (or their) time. Using electronic means allows viewers to jump back and forth, view when they have time, look it over several times. I believe using that freedom effectively is more important.

In my experience, on-line interaction is invaluable in one-on-one contact (or at most a small, as in at most five people or so) group. In larger groups it isn't really effective. Over the 'net the interaction loses much (can't see the body language of "I didn't get that" or "I'm bored"), so I doubt this will be very effective.
