Researchers analyze performance of first updatable holographic 3D display

from PHYSORG:

In 2008, researchers from the University of Arizona created a holographic 3D display that could write and erase images, making it the first updatable (or rewritable) holographic 3D display ever demonstrated.

Now, in a follow-up study, the researchers have reported the results of their analysis on the performance of the display, including how the polymer enables display enhancements and what more needs to be done before such displays can be widely used.

Gesture-based computing on the cheap

from MIT News:

With a single piece of inexpensive hardware — a multicolored glove — MIT researchers are making Minority Report-style interfaces more accessible.

“This actually gets the 3-D configuration of your hand and your fingers,” Wang says. “We get how your fingers are flexing.”

Exhibitors showcase latest glasses-free 3D display, e-paper technologies at Finetech Japan 2010

from Digitimes:

Color e-paper and 3D glasses-free display products were a major attraction at the just concluded Finetech Japan 2010 in Tokyo.

Newsight showcased a series 3D displays requiring no glasses, including a 70-inch model for public display applications. The company claimed that the 70-inch model was the largest 3D display in the world.

Bridgestone displayed a 13.1-inch touchscreen 4,096-color e-paper enabled by color filter (CF).

Intel guru says 3-D Internet will arrive within five years

from ComputerWorld:

Sean Koehl, a technology evangelist with Intel Labs, said technology is emerging that will one day change the way we interact with electronic devices and with each other.

That could come as soon as five years from now when, he predicted, there will be realistic-looking three-dimensional applications.”The Internet may never go fully 3-D, but making 3-D environments broadly accessible is probably capable within five years,” noted Koehl.

MIT’s BiDi Screen: A thin depth-sensing LCD for 3D gesture interaction using light fields

from web.media.mit.edu: <- video, specs, & more at link

The BiDi Screen is an example of a new type of I/O device that possesses the ability to both capture images and display them. This thin, bidirectional screen extends the latest trend in LCD devices, which has seen the incorporation of photo-diodes into every display pixel.

Using a novel optical masking technique developed at the Media Lab, the BiDi Screen can capture lightfield-like quantities, unlocking a wide array of applications from 3-D gesture interaction with CE devices, to seamless video communication.

Researchers create 3D invisibility cloak

from NEXT BIG FUTURE:

Researchers at Germany’s Karlsruhe Institute of Technology report they were able to cloak a tiny bump in a layer of gold, preventing its detection at nearly visible infrared frequencies.

(for illustrative purposes only – no one yet invisibly stalking you)

The cloak is a structure of crystals with air spaces in between, sort of like a woodpile, that bends light, hiding the bump in the gold later beneath, the researchers reported in Thursday’s online edition of the journal Science.
