Wraparound plasma screen is one good turn

Fujitsu converts what looks like your standard building column into an interactive billboard by wrapping it with a plasma display equipped with a motion-sensing camera.

CHIBA, Japan--It turns out digital signs don't have to be flat.

Here at Ceatec, Fujitsu turned what looked like your standard building column into an interactive display by wrapping it with a plasma display and a motion-sensing camera.

The display itself is 1 centimeter thick and is available in much larger sizes--see the 200-inch one that's been installed at Japan's Kansai Airport.

The display uses cameras to sense a person's location and movements in reaction to elements on the screen. The camera on one side displays the person's interactions on both sides of the column, making it appear see-through.

Below is a quick demo of how it works. Here the display is showing a simple demo that allows people to pop some on-screen bubbles, but you can see how ads in a subway or on the street could incorporate far more interaction with an audience passing by.
