Video Images Floating in the Air
The Korea Times reports that "science fiction becomes reality with a new holograph machine." In fact, the devices developed by IO2Technology look impressive. The Heliodisplay, which is about the size of a PC, is fed with images, swallows air and 'modifies' it. When the 'altered' -- but harmless -- air is ejected, it is illuminated to produce a continuous flow of 2D images. A first version, which can project floated images of 22 inches (55 centimeters) in the air, costs $18,600 -- including $9,000 payable in advance.
Even if I agree with the writer of the story that this is an interesting new technology with many possible applications, it's interesting that the company itself says that "although the Heliodisplay uses lasers, the images are not holographic." This overview contains other links and pictures about the Heliodisplay device.
