I see that Microsoft has come out with a coffee-table shaped computer, which represents a pretty major technological step forward in user interface (UI) design by allowing multiple simultaneous inputs directly to the display from more than one user, and even directly from objects placed on or in proximity to the screen. Not your average touchscreen. Popular Mechanics test-drives it (with video) in a fairly extensive report that includes an overview on how it actually works. As new and as groundbreaking as this is, I immediately knew I’d seen it somewhere else before.
