360-Degree Holographic Display

, , , ...

Researchers from the University of Southern California (USC) Institute for Creative Technologies developed a 360-degree holographic display, that projects three-dimensional images that can be seen from any angle at a reasonable distance. The researchers used a set of rendering techniques for their autostereoscopic light field display.

The holographic display system uses a standard programmable graphics' card to render over 5,000 images of interactive 3D graphics per second, projecting images to 360°-degrees with 1.25° degree separation and up to 20 updates per second. The images are projected onto a spinning anisotropic reflector and a motion-tracked vertical parallax is used to support 3D movements with perspective-correct geometric cues.

The USC team demonstrated this technique with interactive raster graphics using a tracking system to measure the viewer's height and distance from the projected images.

E-paper with Photonic Ink

, , ,

Scientists in Canada have used photonic crystals to create a novel type of flexible electronic-paper display. Unlike other such devices, the photonic-crystal display is the first with pixels that can be individually tuned to any color.

"You get much brighter and more-intense colors," says André Arsenault, a chemist at the University of Toronto and cofounder of Opalux, a Toronto-based company commercializing the photonic-crystal technology, called P-Ink.

Several companies, including MIT startup E Ink and French firm Nemoptic, have begun producing products with e-paper displays. E Ink's technology uses a process in which images are created by electrically controlling the movement of black or white particles within tiny microcapsules. Nemoptic's displays are based on twisting nematic liquid crystals. The benefit of such screens is that compared with traditional displays, they are much easier to view in bright sunlight and yet only use a fraction of the power.

Rocketing into HIPerSpace

, , ,

Engineers at the University of California, San Diego have constructed the highest-resolution computer display in the world – with a screen resolution up to 220 million pixels.

The system located at the UCSD division of the California Institute for Telecommunications and Information Technology (Calit2) is also linked via optical fiber to Calit2’s building at UC Irvine, which boasts the previous record holder. The combination – known as the Highly Interactive Parallelized Display Space (HIPerSpace) – can deliver real-time rendered graphics simultaneously across 420 million pixels to audiences in Irvine and San Diego.

“We don’t intend to stop there,” said Falko Kuester, Calit2 professor for visualization and virtual reality and associate professor of structural engineering in UCSD’s Jacobs School of Engineering. “HIPerSpace provides a unique environment for visual analytics and cyberinfrastructure research and we are now seeking funding to double the size of the system at UC San Diego alone to reach half a billion pixels with a one gigapixel distributed display in sight.”

HypoSurface Walls Are Full Of Life

, ,

HypoSurface is a unique display medium in which the surface of the display actually moves. The surface is made of small, interlocking panels that can push out or pull in to create a wide variety of shapes.

The surface behaves like a precisely controlled liquid: waves, patterns, logos, even text emerge and fade continually within its dynamic surface. The human eye is drawn to physical movement, and this gives HypoSurface a basic advantage over other display systems.

The surface of the display can be made to mimic a wide variety of disturbingly biological movements. Letters and logos march across the wall; amoebas and snakes seem to undulate just under the surface (see video)

Interactive 3D-environments based on MPEG-4

, , , ...

Computer scientists at the Fraunhofer Institute for Digital Media Technology (IDMT) have developed a media player for interactive 3D-environments. ‘Our system allows us to actively involve the viewers — they can walk through rooms and select objects, for instance,’ says one researcher. This is possible because each element — a person, a video clip or a sound — can be integrated into the display. And if you’re a — filmed — spectator, your image also can be interactively inserted into the viewer.

For example, here is one scenario imagined by IDMT. “With just one click of the mouse, music-lovers can look over the guitarist’s shoulder in a three-dimensional scenario. The joystick enables viewers at home to ‘walk’ right across the stage and experience the recorded concert from all sides. The surround sound moves with the spectator — if you turn your back to the stage, then the sound seems to be coming from behind.”

Better Than High Definition

, , ,

High-definition displays are increasingly popular. More and more people are experiencing high-definition movies and television in breathtaking color and detail. But another technology, called high-dynamic range (HDR), is on the heels of high definition, and some experts think that it could be a quick successor.

Whereas high-definition displays pump out more pixels, HDR displays provide more contrast. In other words, on an HDR display, the brightest whites are hundreds of thousands of times brighter than the darkest blacks; the contrast is key to making images on such a display appear more realistic.

"A regular image just looks like a depiction of a scene," says Roland Fleming, a research scientist at the Max Planck Institute for Biological Cybernetics, in Tübingin, Germany. "But high-dynamic range looks like looking through a window."

SeeReal Hi-Res Holographic Display

, , , ...

German company SeeReal demonstrated a new holographic display at the SID 2007.

The holographic display prototype uses a 20 inch display that displays a real high-resolution 3D image in front the screen. SeeReal only uses an approx. 30x30 pixel array for each of the 3D scene points - the so-called "sub-hologram" approach.

Overlapping all of these sub-holograms on the data panel allows creating a Full-HD 3D scene while using LCD flat panel displays with resolutions available today, e.g. 30-50µm pixels for a 40-60" holographic HDTV.

The holographic display uses an eye tracker to know where your eyes are located, to send information only to these positions.

Researchers show off virtual human in 4D

, , ,

Canadian researchers say they have developed the most detailed model of a human yet, a movable "4D" image that doctors can use to plan complex surgery or show patients what ailments look like inside their bodies.

Called Caveman, the larger-than-life computer image encompasses more than 3,000 distinct body parts, all viewed in a booth that gives the image height, width and depth, the researchers said Wednesday.

Caveman also plots the passage of time--the fourth "D."

Scientists can layer on the unique visuals of patients, such as magnetic resonance images, CAT scans and X-rays, giving physicians high-resolution views of the inner workings of the body while it appears to float within arm's reach.

Tiny TV is Bendable

, ,

In the race for ever-thinner displays for TVs, cell phones and other gadgets, Sony may have developed one to beat them all — a razor-thin display that bends like paper while showing full-color video.
VIDEO: See the Bending TV in Action
Sony Corp. released video of the new 2.5-inch display Friday. In it, a hand squeezes a display that is 0.3 millimeters, or 0.01 inch, thick. The display shows color images of a bicyclist stuntman and a picturesque lake.

Although flat-panel TVs are getting slimmer, a display that's so thin it bends in a human hand marks a breakthrough.

Sony said it has yet to decide on commercial products using the technology.

Live Ink offers better way to read text online

, , ,

Did you know our primitive brains weren’t wired very well to read this paragraph?

Scientific research conducted by Walker Reading Technologies, a small Minnesota startup that has been studying our ability to read for the last ten years, has concluded that the natural field of focus for our eyes is circular, so our eyes view the printed page as if we’re peering through a straw.

And a very bad-behaving straw at that, because not only do our eyes feed our brain the words we’re reading, they’re also uploading characters and words from the two sentences above and below the line we’re reading.

Every time we read block text, we’re forcing our brain to a wage a constant subconscious battle with itself to filter and discard the superfluous inputs. This mental tug of war slows reading speed and diminishes comprehension.

Walker Reading Technologies’ CEO and co-founder, Randall Walker MD, believes he and his team have developed a solution with a product called Live Ink that allows online publishers to improve reading speed and comprehension. Live Ink works by analyzing written language for meaning and language structure, and then applies algorithms that reformat the text into a series of short, cascading phrases. It breaks complex syntax into simpler syntax, which makes it easier for the brain to absorb the material.
