This is quite old, I don't know if someone has already posted it.
I found this site io2technology
It is about a guy from MIT who developed virtual display - now it's patent pending. IT IS NOT A HOLOGRAPHY! The image is produced by only by ejecting
Description from the site:
"Air comes into the device, is modified, then ejected and illuminated to produce the image. Nothing is added to the air so there isn`t any harmful
gas or liquid emitted from the device, and nothing needs to be refilled.
The images are easily viewed in an office environment. Like any computer monitor or TV, images appear brighter the lower the ambient light. Also, just
like viewing any computer monitor or TV, viewing a Heliodisplay in direct sunlight is almost impossible.
Images can be seen up to 75° off aspect for a total viewing area of over 150° -- similar to an LCD screen. Viewing requires no special glasses or
The image is planar (2D), not volumetric (3D). Like any computer monitor, it can project simulated 3D. Sometimes such images will look like real 3D
when viewed from more than a few feet away because there is no physical depth reference.
The Heliodisplay is backward compatible and accepts most 2D video sources (PC, TV, DVD, HDTV, Video game consoles). For connection to a computer, the
Heliodisplay uses a standard monitor VGA connection; for TV or DVD viewing, it connects using a standard RGB video cable.
This Heliodisplay is FULLY INTERACTIVE, like a virtual touchscreen. A hand or finger can act as a mouse. No special glove or pointing device is
required. Just as you use a mouse to move the cursor on a traditional computer monitor, you can use your finger to move the cursor around the
In the course of developing the technology, We have built Heliodisplays that displayed images ranging from 5" (12cm) to 42" (105cm). The device, and
thus the projected image, can be oriented vertically or horizontally. Devices can be ganged together for one long (or high) continuous image. The
technology can be customized (image size, image resolution; interactivity) for different applications. "
Potencial aplications are military, TV, computer, displays in museums etc...
Look at the site for more images+some videos.
Technology is not perfect yet, but it would be nice to have 1 at home.
. The price should be comparable to plasma and LCD displays.
