Answers.Body: <p>Upon closer examination of the sample video, she is not writing what you are seeing, her movement only approximates the motion and if you look close enough you can see it is a mime--take a good look at the "E". She is not moving correctly to get that "E". I don't know what resources you have to work with, but if you want to copy this technique you need to have 2 things:</p>
  
  <p>1) an actor that can closely mimic the correct motion as if she/he is really writing.
  2) a good post production video editor so you can animate the writing content on a separate video track and make a composite.</p>
  
  <p>Hope this helps</p>
  
  <p>ps, by the way I think the actor in your example did a marvelous job of miming the motion to trick us into believing she was actually writing the text on glass.</p>

  The easiest bet is to actually draw on a piece of glass and there are actually boards made for just that purpose for the classroom. It is probable one of those is being used here and the video reversed to make it readable from the other side. This seems likely as the video shows the guy left handed and the buttons are on the wrong side of his shirt.
  
  The same look can kind of be achieved using write-on effects and/or animation, but you would still need some prop for the speaker to interact with so that they position their hand in roughly the right area and it still wouldn't like up exactly.
  
  Doing this kind of shot practically is the best way to achieve it.
