Video Screen in Thin Air

Agent Provocateur writes "CNN has a story about inventions in advanced computer displays -- eliminating the screen altogether."Ever since the movie 'Star Wars' came out and there was a distress call from Princess Leia," -- generated in thin air by the robot R2D2 -- "people all over the world have been wanting one of these." While unlikely to replace the desktop computer monitor, so-called walk-through displays could eventually be put to use in product showrooms and museums."

      Not even close to Holodeck technology. The holodeck actually creates objects for its user to interact with using the same energy matter system that the transporter system moves objects from ship to planet and back. The only real difference between the two systems is that the transporter begins with matter then transforms it into energy which is then transmitted to a remote location for reconstruction, while the holodeck begins with energy which is configured in an "image matrix" to create the object within the confines of the holodeck or vacinity of a holodeck generator.

      The article mentions two technologies. One is the fog screen (as seen at SIGGRAPH), where the fog unit hangs from the ceiling and its clearly-visible vapor flows downward.

      This other technology seems to involve a "sit on your desk" unit, out of which some kind of vapor appears to blow upwards. They have three videos showing this on their website (IO2 Technology) although it's light on technical specifics. The vids are filmed from in front of the unit, which seems to have a more extensive projection system hiding back behind it -- which as the guy moves his hand into the image, you can see projecting bright light up onto his arm. The "sheet" of vapor is surprisingly transparent, but you can notice its "laminar flow" being disrupted by his hand movement.

      I, too, have my questions: What the vapor is and if it's toxic or messy... and how he'll do 3D (which is implied as being the next step) because the technology I see is basically a 2D "screen" and a long way from 3D.

      Obviously, you want to convert the air to form a mirror of some sort to form a superior mirage effect. So, the simplest solution would be to implement some cooling system to create the cool air layer, and use the heat of the projector to create the warm air layer. Once you have this boundary layer, you should have an air mirror and maybe a holographic image.

There is no surgeon in the world that I know of, that would obscure the surgical field with yet another thing to block their vision. So if applicable to learning surgery, it would have to be in a non-operative setting, and so not having a screen isn't very important at all.

    There are many other things of much more importance to a budding surgeon - such as the organ texture, learning how to suture, trying to identify the diseased thing that you're holding in your hand, how things behave, etc. No one in the surgical field will bother with this, I don't think I would and I love computers/gadgets.
