I saw this on It's All Good and wanted to share it with you. As George from OCLC said, it's a "touch screen on steroids." I was pretty amazed by what I saw. I'm not sure how well this is developed at this point, but it will be convergence of a lot of different technologies when/if it comes together. Essentially it's a computer within a coffee table that you can touch to find information, download pictures, or order items. You can also place physical objects on it. For example a user could place a digital camera on the screen. Instead of working through software to download the pictures, they appeared instantly with no work on the part of the user.

I can think of some library uses already. Customers could place a book on the screen and get reader's advisory. They could pay library fines, find out more about the library or even the community. I'm sure there are other uses for it as well.
