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?

  • you can try with team viewer connection on your tab to other devices – codercat Dec 26 '13 at 11:00
  • To close-voters: This question seems perfectly fine (after a little re-phrasing I've just applied, at least). Remember there are features like screen mirroring, which might even be pre-installed. – Izzy Dec 26 '13 at 14:28
  • Izzy's answer is (as typical of Izzy) fantastic. I'll just break form a bit and insert my own experience with tablets in the classroom: Android tablets for projection are a great idea in theory, but have been a pain in practice. The best results I had for doing real-time annotation and various projection tasks were (disappointingly, considering how I'm a big Android fan) with x86 Windows (Non-RT) tablets. Combining Miracast with generally excellent app and stylus support makes a winning device in the classroom - but expensive. – dotVezz Dec 26 '13 at 20:02

This is definitly possible. There are even multiple approaches I could think of:

  • Screen mirroring
    Some devices already ship with this functionality. My sister e.g. just got her new Samsung Galaxy S4 mini which I helped her to set up, and I noted a related "toggle" in the notification bar to switch "mirroring" on/off. Also, newer builds of the custom ROM IMHO offer this feature. Especially via HDMI, this also should be supported (maybe requiring an additional app).
  • Remote Tools
    iDev already mentioned Team Viewer in his comment. While the specific component to remote access the Android device itself only exists for few devices (the list might grow, some time given), there are several similar/comparable solutions, as VNC.
  • Other means
    There might also exist specific "whiteboard apps", designed for exactly this purpose. I don't know such one (but I didn't explicitly check for), but searching the Playstore cannot hurt (to ease this, as the "official Google Play website is quite restricted in its search capabilities since its relaunch, I recommend using AppBrain for searching; it's an alternative "web frontend" to Google Play).
  • Thank you everyone for the wonderful answers. I've realized two things: 1. I did a poor job of asking the question I was actually thinking and 2. I hadn't thought through the process of connecting a tablet to a projector very well. The question I actually was trying to answer (it turns out) was asked and answered in this thread. Nonetheless thank you for the answers, I will look into these options as well as the ones in the other thread. – Sonny Dec 27 '13 at 7:01
  • But you did not only a good job locating that other question, but also to link it by mentioning it in a comment here! That promises a great future for you on our site :) – Izzy Dec 27 '13 at 18:57

The easiest way is, if your projector supports wifi connection then any android device will work(phone/tablet) with appropriate application. And to view pdfs + to write on it just use Adobe Reader.

Or, you can just install Droid@screen to do it for you link is this

hope this helps. :)
