Oh, I thought the lower screen was an e ink display, sort of like simulating a sheet of paper there. I don't like the lower screen with a projector - then the

  Presumably, if you're reaching across the pad, you're looking at the monitor, and if you're touching something on the pad then you probably can't see through your arms/hands anyway. That being said, I think a second screen would be preferable all the same, but it would probably bump the cost significantly.

    Screens are [comparatively] cheap, esp. Vs a custom projector + touchpad + 3d camera set-up. I don't think they went this route to save on production costs.

  I think it's an interesting approach. There are some things you can do with a projector that you couldn't do with another screen (http://www.youtube.com/watch?v=j9JXtTj0mzE http://www.youtube.com/watch?v=j9JXtTj0mzE) I could see some applications taking advantage of this when it comes to working with physical items

  I was also quite confused about why they would choose a projector over a second screen, actually it was the most nagging question until, watching the intro video, someone projects a graphic onto a physical sheet of paper, so I suppose the immediate interaction between projection and physical objects is the main reasoning behind it. In a two screen scenario, I suppose the user would have to image the paper, then composite it digitally. It's an interesting approach although I wonder how often it would be used.

  When you have a physical 3-dimensional object you can use the projector cast images on it. I wonder if it is used for calibrating and lining up objects for the 3D camera as well.
