What makes it a better solution? Albeit a bit "life hack"-y, this is something that requires no technical skill or support, and is easily assembled from household items, so very little outlay. I don't think I'd concede that webcams are a better solution, when thinking as an underfunded body such as a school district who may have to provide support for potentially thousands of these webcams to work for all their teachers. Furthermore, I don't think this is something that we should hold the individual teacher responsible for: teaching is already a full time job, and workers should not have to buy their own equipment to do their job with, something that already happens too much in that field. I did also think the writing on the keyboard might prove problematic, but also the teacher could theoretically remove the notepad and place it back if they wished. It's a relatively "open" technique.
