Most of us remember the scene in the 1977 movie "Star Wars" in which the robot R2-D2 projects a three-dimensional image of Princess Leia, who begs Obi-Wan Kenobi for help: "This is our most desperate hour. Help me, Obi-Wan Kenobi. You're my only hope." Seeing that film years ago planted the desire in many of us to see this kind of technology brought to life. After all these long years of waiting, portable holography has finally arrived.
IO2 Technology announced that it has completed a working prototype of what the company is calling the Heliodisplay, a three-dimensional display that uses no screen whatsoever but can project TV, video and computer images into free space. The company's technology makes it possible for users to walk around -- or even through -- the floating images projected into air.
The unit, which is about the size of a bread box, can project images as large as 27 inches and will have the ability to expand to 150 inches with future releases. As far-fetched as it sounds, the device has interactive capabilities as well. Images can be manipulated just as though they were displayed on a conventional computer monitor, but instead of using a mouse, a viewer can use a hand to move an image or a finger to move the cursor and select an object.

Not only does it display video in the air, it is also touchscreen or should I say touch-air?
