On Coursera, how does the text written by a person facing the camera appear correct?

I’m taking a Coursera class, and the videos show an instructor facing the camera while talking. He writes on the “screen”, using his right hand, and the notes appear correctly (also facing me) as if drawn on a glass window between us. How is this accomplished without him actually writing backwards a la Da Vinci? He is clearly writing on something board-sized.

With practice it’s not that difficult to write flipped… I used to get quite bored in high school and I’d try and write flipped both ways (vertically and horizontally) for example… Compared to some of the classes I had to attend that felt like a fun challenge to do.

Or maybe your teacher is left handed and the video is flipped…

The presenter is writing on a piece of glass with the camera looking through, so the raw video will have the text reversed.
They just flip/reverse the clip and like magic everything is the right way round.
Think of it like taking a selfie using a mirror. The image in your phone is backwards, but if you look at the image using the mirror it is all good.
