    Once again, reality catches up with science fiction

    Making a video screen out of thin air

    Monday, September 15, 2003 Posted: 11:10 AM EDT (1510 GMT)


    SAN FRANCISCO, California (Reuters) -- In a museum in Tampere, Finland, Ismo Rakkolainen's fog machine conjures up the Mona Lisa on an invisible sheet of water particles.

    Thousands of miles away in Hermosa Beach, California, a graduate student passes his hand through an image of a DNA strand produced -- apparently out of thin air -- by a modified video projector.

    The two inventions represent the latest front in advanced computer displays -- eliminating the screen altogether.

    While unlikely to replace the desktop computer monitor, so-called walk-through displays could eventually be put to use in product showrooms, museums, and military training facilities.

    "This is something that people have been dreaming about for a long time," said Chad Dyner, 29, a graduate student at the Massachusetts Institute of Technology and inventor of Heliodisplay, one of the prototype display systems. "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."

    'There is a greater darkness than the one we fight. It is the darkness of the soul that has lost its way. The war we fight is not against powers and principalities, it is against chaos and despair. Greater than the death of flesh is the death of hope, the death of dreams. Against this peril we can never surrender. The future is all around us, waiting, in moments of transition, to be born in moments of revelation. No one knows the shape of that future or where it will take us. We know only that it is always born in pain.'"

      yeah, except it probably costs way too much.

        I read the article... forgive me, but how exactly does it differ from a hologram? It's still a machine that conjures a picture in air above it, isn't it?

                but you still can't have sex with the projections.

                Now when the day you can have sex with these projections and feel like the real thing. Well then you can kiss reality goodbye.

                  Wow, so you can use a screen of fog instead of a projection sheet. Amazing!.

                  How exactly does this change anything, except by lowering the image quality and making the process more complicated?

                    well teachers won't have to pull that screen down when showing a movie to their students .

                    And then the schools can say they need billions of dollars to educate their students properly.

                      When are they going to give us polarised photons? Or what do they use in those holo-decks in ST?

                            It's not 3 dimensional. That would be impossible using this method... it would require synchronized projectors all around the fog, and the fog would have to be in a very exact form for it to represent a 3D image.
