3-D Viewing without Goofy Glasses

June 12, 2008

Philips’ WOWvx displays–which allow viewers to perceive high-quality 3-D images without the need for special glasses–are now beginning to appear in shopping malls, movie-theater lobbies, and theme parks worldwide.

The technology uses image-processing software, plus display hardware that includes sheets of tiny lenses atop LCD screens. The lenses project slightly different images to viewers’ left and right eyes, which the brain translates into a perception of depth.

3-D Without the Glasses

A new type of lens developed by Microsoft researchers makes it possible to to show different images to different viewers, or to create a stereoscopic (3-D) effect by presenting different images to a person’s left and right eye.

3-D, and Ditch the Glasses

April 19, 2002

A number of 3-D displays currently being developed “open up a whole new world for medicine, science and other professions that rely on complex visualizations” as well as video games.

For example, the autostereoscopic display currently under development at NYU eliminates the need for glasses, can be seen from a variety of viewing angles, and allows users to see a unique picture depending on where they sit.

3-telescope interferometry allows astrophysicists to observe how black holes are fueled

By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, yielding an unprecedented amount of data for such observations.

The resolution at which they were able to observe this highly luminescent active galactic nucleus (AGN) has given them direct confirmation of how… read more

30-year robot project pitched

August 21, 2003

Japanese researchers in robot technology are advocating a grand project, under which the government would spend 50 billion yen a year over three decades to develop a humanoid robot with the mental, physical and emotional capacity of a 5-year-old human.

35 hours of video per minute uploaded to YouTube

November 12, 2010

(YouTube blog)

More than 35 hours of video are uploaded to YouTube per minute, or 50,400 hours uploaded every day — the equivalent of more than 176,000 full-length Hollywood releases every week.

Here are some of the factors contributing to the growth:

  • The time limit for videos uploaded by users increased by 50% from 10 to 15 minutes.
  • The upload file size increased over the last few

3D acoustic cloaking device makes objects undetectable with sound

March 13, 2014

Using a few perforated sheets of plastic and extensive computation, Duke University engineers have demonstrated the world’s first three-dimensional acoustic cloak.

The new device reroutes sound waves to create the impression that both the cloak and anything beneath it are not there.

The acoustic cloaking device works in three dimensions, no matter which direction the sound is coming from or where the observer is located, and holds potential… read more

3D art for all: Ready to print

May 16, 2011

Makerbot, a leading company in the field of 3D printing that has sold over 4,500 machines, has been putting the ability to manufacture custom plastic “prints” in the hands of anyone with $1,300 to buy one of their machines. The technology, called “3D printing” or “rapid prototyping,” has existed for years, but is only recently gaining a foothold among everyday tinkerers.

3D audio system developed by MP3 pioneer

July 28, 2004

A sound system that creates immersive, three-dimensional audio for everyone in a room has been developed by one of the creators of the MP3 audio format.

It uses a principle known as “wave field synthesis” to create complex audio illusions for everyone within a defined space. Computers are used to predict the way multiple sound waves will interact with each other within a space. Then, a multitude of small… read more

3D bio-printers to print skin and body parts

Scientists are developing 3D “bioprinters” that will be able to print out skin, cartilage, bone, and other body parts.

Professor James Yoo, from the Institute of Regenerative Medicine at Wake Forest University is developing a system that will allow them to print skin directly onto burn wounds. The bioprinter has a built-in laser scanner that scans the wound and determines its depth and area. The scan is converted into… read more

3D chip stacking to take Moore’s Law past 2020

March 12, 2010

3D Microchips

By combining 3D-stack-architecture of multiple cores with hair-thin, liquid-cooled microchannels, IBM and Swiss Federal Institute of Technology Zurich hope to extend Moore’s law for another decade or more.

3D chip stacks with interlayer cooling overcome the bandwidth bottleneck between core and cache memory and allow for systems with a much higher efficiency, so supercomputers won’t consume too much energy to be affordable.

To solve the… read more

3D copying makes Michelangelos of the masses

Cosmo Wenman went to the J. Paul Getty Museum in Los Angeles, took hundreds of pictures, documenting busts and reliefs from every accessible angle, and turned the photos into three-dimensional digital maps, using a free program called Autodesk 123D Catch.

Then he used the maps to print miniature plastic replicas on the $2,000 MakerBot 3-D printer in his home office.

And he… read more

3D counterpart to graphene discovered [UPDATE]

Promises faster transistors and more compact hard drives

DOE Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have discovered that sodium bismuthide can exist as a form of matter called a “three-dimensional topological Dirac semi-metal” (3DTDS).

“A 3DTDS is a natural three-dimensional counterpart to graphene with similar or even better electron mobility and velocity,” says Yulin Chen, a physicist with Berkeley Lab’s Advanced Light Source (ALS) when he initiated the study that led to this discovery,… read more

3D ‘Crystal Ball’ Monitors

May 1, 2003

Perspecta, a new display technology using a rotating disk, provides a high-resolution 3D representation of an object that can be viewed from 360 degrees around the display, without the need for special goggles.

3D Display Offers Glimpse of Future Media

November 10, 2008

A 3D display system, developed by University of Southern California researchers, could one day transform visual entertainment.

The 3D display can project both virtual as well as real images from a recorded movie, is autosterescopic (viewers don´t need to wear special viewing glasses to see the 3D effects), and is also omnidirectional, so that multiple viewers can watch the display from all directions and heights.
