[kinda ot] use a wiimote to turn anything into a touch screen display
the setup, if you dont have bluetooth on your laptop/ desktop or you dont have a wii controller, is around 50- 60 dollars.
the main part i want you guys to see is at 3 minutes, but i recommend watching the whole thing. also, to understant the whole concept better you should watch these (in order of importance):
these are the only 3 ive watched so far, so i might add more later.
