BoardOnAir™ is based on the open sourced project by Michael Peshkin of the Northwestern University. It wascarried out by Carlo Mariconda and Alberto Tonolo of the Department of Mathematics “Tullio Levi-Civita” of the University of Padua in collaboration with the illusionist Frank Cadillac. It is already being used by the Padua University teachers to create numerous educational videos for courses and Moocs on the prestigious international platform Futurelearn:
The professor, writing on the board or on the screened images is framed frontally. Differently from a chroma-key shooting, the lecturer is able to see the screened slides and to easily point at them.
