I remember hearing about a Xerox research lab that had a whole room where the walls were all whiteboard.
They had a celling mounted camera that would scan the walls.
They also had a markup language that the camera OCR software would pick up. So for example if they drew a P in a square, it would print out that wall to the printer.
If they wrote an e-mail address in a square it would e-mail a photo of the whiteboard to that e-mail address.
This was 7 or 8 years ago. I wonder if they still use this system.
I heard about it 7 or 8 years ago from people who had been to Xerox Parc and Cambridge (UK) based Xerox Research Centres.
I can find this research paper online, although it appears to be dated 1995. It's not exactly what I was told about, but it seems to be an earlier version.
