I am looking for a method to save the lecture materials, and examples without hand copying from the boards during the lectures. Unfortunately some courses don't have the material available, and sometimes you want to copy a specific example.
EDIT: The reason I would like to avoid copying by hand is that it is sometimes very distracting, especially when the example is complex. I would like to focus on the material itself and devote less time and effort to handwriting it.
So far I thought of using a tablet with an application such as Camscanner to take photos of the board during the lectures. However sometimes I would want to add a hand note or an notation on the photo itself using a stylus pen (or similar).
UPDATE: Camscanner will auto recognize the board boundaries for you and fix the perspective. Also once you took one photo you automatically add subsequent photos to the same document, i.e. same lecture. Very handful feature is that you can add hand notes on the image right after taking it, making notations easy.
Any advice on an effective method or an application designed for that?
