I currently do not own a smartphone or a tablet, but am interested in getting one or both that could help me with the following:
I am a teacher. I regularly have notes displayed on an overhead projector AND simultaneously write on a chalkboard. I would like to be able to write (using a stylus) directly onto the screen on top of what I am displaying.
I usually display notes in PDF or Powerpoint. If it would be possible to then save the written notes on the file would be a major plus, though not necessary.
Is this possible with Android devices – and if so, how could it be done?
