Life-size 3-D hologram-like telepods may revolutionize videoconferencing in the future

Life-size 3-D hologram-like telepods may revolutionize videoconferencing in the future: Two people simply stand infront of their own life-size cylindrical pods and talks to a 3D hologram-like images of each other. Cameras capture and track 3D video and convert into the life-size image.

Since the 3D video image is visible 360 degrees around the Pod, the person can walk around it to see the other person's side or back...


Dr. Vertegaal and his team used mostly existing hardware – including a 3D projector, a 1.8 metre-tall translucent acrylic cylinder and a convex mirror.

3-D Projection Tech Makes Images Hover in Mid-Air, No Screen Necessary

3-D Projection Tech Makes Images Hover in Mid-Air, No Screen Necessary: Rather than using a screen to generate the illusion of three dimensions, Aerial 3D is a laser system that uses beams of light projected from below to generate plasma excitation in atoms of oxygen and nitrogen in the air. It currently can create 50,000 points of light per second, giving it a somewhat choppy frame rate of 10-15 fps. Burton is working to improve that to 24-30 fps, comparable to that of basic video.

DARPA SUCCESSFULLY COMPLETES 3D HOLOGRAPHIC DISPLAY TECHNOLOGY DEMONSTRATION PROGRAM

Defense Advanced Research Projects Agency: It permits simultaneous viewing for up to 20 participants and is interactive, allowing the image to be frozen, rotated and zoomed up to the resolution limit of the data. The holographic display enables full visual depth capability up to 12 inches. The technology also enables realistic two-dimensional printouts of the 3D imagery that front line troops can take with them on missions.

UPSD is based on full-parallax technology, which enables each 3D holographic object to project the correct amount of light that the original object possessed in each direction, for full 360- degree viewing.  Current 3D displays lack full-parallax and only provide 3D viewing from certain angles with typically only three to four inches of visual depth.

3D, 360-degree fog display shown off (w/ video)

3D, 360-degree fog display shown off (w/ video): Researchers at Osaka University in Japan have made a 3D and 360-degree display that projects from a variety of different angles onto a cylindrical fog display. This combination of multiple-point of view projectors and the cylinder allows for a display that is 3D no matter what side you view it from, though in order to get a holodeck style of projection a much larger set of projectors, and a lot more fog, would need to be on hand.

This Isn't a Jellyfish, It's a 3D Camera Made From 100 Small Lenses

This Isn't a Jellyfish, It's a 3D Camera Made From 100 Small Lenses: According to its creators at the École Polytechnique Fédérale de Lausanne in Switzerland, the camera was modeled after a fly's eye—which you may remember from school is able to see in all possible directions. When connected to a computer, the images from all 100 cameras are combined for the ultimate 3D movie.

A Step toward Holographic Videoconferencing - Technology Review

A Step toward Holographic Videoconferencing - Technology Review: "By improving the materials used to make the display and the optical system used to encode the images, they have now demonstrated a full-color holographic display that refreshes every two seconds. This work is described today in the journal Nature.

The key to the technology is a light-responsive polymer composite layered on a 12-inch-by-12-inch substrate and sandwiched between transparent electrodes. The composite is arranged in regions called "hogels" that are the holographic equivalent of pixels. Writing data to the hogels is complex, and many different compounds in the composite play a role. When a hogel is illuminated by an interference pattern produced by two green laser beams, a compound called a sensitizer absorbs light, and positive and negative charges in the sensitizer are separated. A polymer in the composite that's much more conductive to positive charges than negative ones pulls the positive charges away.

This charge separation generates an electrical field that in turn changes the orientation of red, green, and blue dye molecules in the composite. This change in orientation changes the way these molecules scatter light. It's this scattering that generates a 3-D effect. When the hogel is illuminated with light from an LED, it will scatter the light to make up one visual point in the hologram."

Floating 3D virtual objects appear at British Library - tech - 15 October 2010 - New Scientist

Floating 3D virtual objects appear at British Library: The RayModeler prototype, developed by Sony, is on display for the first time in the UK at an exhibit at the British Library, London, called Growing Knowledge. The device creates 3D images that viewers can see from all angles without stereoscopic glasses. Sensors that recognise gestures allow it to be spun around when you wave your hand in the desired direction.

Reactive Cube: "It works by projecting a two dimensional image through a three dimensional mass - in this case water mixed with specially formulated emulsion. The emulsion is composed of micron-sized particles of oil formulated to stay suspended in water."

Sony 360-Degree Volumetric Display: the Stuff Sci-Fi Dreams Are Made of - Technabob: The new autostereoscopic display projects 360 individual slices of an image onto an array of special LEDs, providing a volumetric display you can walk around and view from any angle – without glasses. It can even recognize gestures, allowing you to manipulate the object displayed on screen.
