You can build more than you might expect with just a little bit of air flow and two microns of water. Like a virtual touchscreen display that appears out of nowhere. That's what Displair can boast anyway, with one of the more eye-catching demos I saw at CES 2013.
Air flows out of the device, interacting with water drops to form a screen where you can beam images from a computer or tablet. But this is no mere projection screen, it's a fully interactive display, as I found it when I was able to play a game of Fruit Ninja just by waving my hand across the Displair's virtual screen.
Displair's Alexander Chachava touted the device's energy efficiency and eco-friendly features when we talked. And it's certainly cleaner than a regular display. It's kind of hard to leave smudges on a screen made up of air, after all.
Is it practical? It could be, even with a $10,000 price tag, if the company succeeds in its goal of having developers build customized apps that fully take advantage of the gesture controls Displair could support. We'll know more later this year when the Displair is slated to arrive by the second quarter of 2013.
