MIT Develops Holographic, Glasses-Free 3D TV 98

Posted by samzenpus
from the realer-than-real dept.
MrSeb writes "Engineers at the Massachusetts Institute of Technology (MIT) are busy working on a type of 3D display capable of presenting a 3D image without eye gear. What you've been presented with at your local cinema (with 3D glasses) or on your Nintendo 3DS console (with your naked eye) pales in comparison to what these guys and gals are trying to develop: a truly immersive 3D experience, not unlike a hologram, that changes perspective as you move around. The project is called High Rank 3D (HR3D). To begin with, HR3D involved a sandwich of two LCD displays, and advanced algorithms for generating top and bottom images that change with varying perspectives. With literally hundreds of perspectives needed to accommodate a moving viewer, maintaining a realistic 3D illusion would require a display with a 1,000Hz refresh rate. To get around this issue, the MIT team introduced a third LCD screen to the mix. This third layer brings the refresh rate requirement down to a much more manageable 360Hz — almost within range of commercially produced LCD panels."

A Million-Year Hard Disk 394

from the sapphires-are-forever dept.
sciencehabit writes "Pity the builders of nuclear waste repositories. They have to preserve records of what they've buried and where, not for a few years but for tens of thousands of years, perhaps even millions. Trouble is, no current storage medium lasts that long. Today, Patrick Charton of the French nuclear waste management agency ANDRA presented one possible solution to the problem: a sapphire disk inside which information is engraved using platinum. The prototype shown costs €25,000 to make, but Charton says it will survive for a million years. The aim, Charton says, is to provide 'information for future archaeologists.' But, he concedes: 'We have no idea what language to write it in.'"

PC Sales Are Flat-Lining 485

from the more-like-personal-computer-is-changing-its-meaning dept.
DavidGilbert99 writes "Gartner has released figures showing that PC shipments globally declined 0.1 percent in the last three months, making it the seventh consecutive month of little-to-no growth in the PC market. This was despite the launch a number of new Ultrabooks, the much-vaunted slim-and-light platform promoted by Intel. The decline has been put down to the poor economic situation around the globe, increased spending on tablets and smartphones instead of PCs as well as the imminent launch of Windows 8, making people hold out on updating their PCs."

judgecorp writes "The parts for a Google Nexus 7 tablet cost only $18 more than the materials for an Amazon Kindle Fire, according to a teardown by IHS. This means while Amazon initially took a loss on each tablet sold, Google will break even on its 8Gb tablet, and make a small profit on the 16Gb model."

The DHS's Latest Investment: Terahertz Laser Scanners 169

MrSeb writes "It seems like every time I set foot in an airport, there is some new machine I need to stand in, walk through, or put my shoes on. The argument can be made that much of this is security theater — an effort to just make things look safe. However, if a new kind of laser-based molecular scanner lives up to its promise and finds its way into airports as planned, it could actually make a difference. A company called Genia Photonics has developed a programmable picosecond laser that is capable of spotting trace amounts of a variety of substances. Genia claims that the system can detect explosives, chemical agents, and hazardous biological substances at up to 50 meters. This device relies on classic spectroscopy; just a very advanced form of it. In the case of Genia's scanner, it is using far-infrared radiation in the terahertz band. This is why the U.S. Department of Homeland Security is so keen on getting it into airports. Understandably, some are calling foul on the possible privacy concerns, but this technology is halfway to a Star Trek tricorder."

Is It Time To End Our Love Affair With the QWERTY Keyboard? 557

from the just-need-a-little-spacebar dept.
Master Moose writes "Brisbane-based entrepreneur John Lambie currently has in beta an alternative to what he calls the 'dysfunctional' QWERTY keyboard. Given the way the world is abandoning their keyboards for smartphones he sees now as the perfect time to introduce a new layout. He calls his new keyboard Dextr and believes it is the natural progression from using a number pad to enter text — This is especially so in developing countries where users have not grown up with QWERTYs on thier phones. While he is not the first to ever propose an alternate or alphabetical keyboard — Are we locked into QWERTY for familiarity's sake, or as we shift to smaller, more mobile and new devices, is Mr. Lambie's project coming at the right time?"

Intel Invests In ASML To Boost Extreme UV Lithography, 450mm Wafers 61

Posted by Soulskill
from the future-tech-is-bloody-expensive dept.
MrSeb writes "When Intel goes looking for new chip manufacturing technology to invest in, the company doesn't play for pennies. Chipzilla has announced a major investment and partial purchase of lithography equipment developer ASML. Intel has agreed to invest €829 million (~$1B USD) in ASML's R&D programs for EUV and 450mm wafer deployment, to purchase €1.7B worth of ASML shares ($2.1B USD, or roughly 10% of the total shares available) and to invest general R&D funds totaling €3.3B (~$4.1B USD). The goal is to bring 450mm wafer technology and extreme ultraviolet lithography (EUVL) within reach despite the challenges facing both deployments. Moving to 450mm wafers is a transition Intel and TSMC have backed for years, while smaller foundries (including GlobalFoundries, UMC, and Chartered, when it existed as a separate entity) have dug in their heels against the shift — mostly because the shift costs an insane amount of money. It's effectively impossible to retrofit 300mm equipment for 450mm wafers, which makes shifting from one to the other extremely expensive. EUVL is a technology that's been percolating in the background for years, but the deployment time frame has slipped steadily outwards as problems stubbornly refused to roll over and solve themselves. Basically, this investment is a signal from Intel that it intends to push its technological advantage over TSMC, GloFo, UMC, and Samsung, even further."

A Fresh Look At Multi-Screen PC Gaming 146

Posted by Soulskill
from the so-many-pixels-so-little-time dept.
crookedvulture writes "It has been quite a while since Slashdot last covered multi-monitor gaming. A lot has changed in the interim. Monitors prices continue to fall, and improved AMD Eyefinity and Nvidia Surround implementations make creating multi-display arrays incredibly easy. Graphics cards have gotten faster, allowing high-end models to handle the latest games at the ultra-high resolutions that multi-screen setups enable. Developers are doing a better job of supporting those resolutions, too, although HUD placement and single-screen cinematics are still problematic in some titles. Even in the games that do have niggling flaws, the wider perspective of a triple-screen config can offer a more engaging and immersive experience. As stereoscopic 3D implementations fail to catch on, multi-screen setups look like the best upgrade for PC gamers."

theodp writes "Back in 2006, a post on Jeff Han's multi-touch screen technology — a real TED crowd-pleaser — gave Slashdot readers a taste of the iPhone and iPad future. Han spun off his NYU Research into a company called Perceptive Pixel which, among other things, gave the world CNN's Amazing Magic Wall. On Monday, Steve Ballmer announced that Microsoft is acquiring Perceptive Pixel, which not only means you'll be able to run Windows 8 on an 82-inch touchscreen, but that the Apple v,.

Student Creates World's Fastest Shoe With a Printer 144

Posted by samzenpus
from the if-you-print-it-they-will-run dept.
An anonymous reader writes "Engineer and designer Luc Fusaro from the Royal College of Art in London has developed a prototype running shoe that can be uniquely sculpted to any athlete's foot. It's as light as a feather too, weighing in at 96 grams. The prototype is aptly named, Designed to Win, and is 3D printed out of nylon polyamide powder, which is a very strong and lightweight material. The manufacturing process uses selective laser sintering (SLS), which fuses powdered materials with a CO2 laser to create an object. This process means 3D scans can be taken of the runner's foot so as to ensure the shoe matches the shape perfectly. Fusaro can also change the stiffness of the soles according to the athlete's physical abilities. The shoe can improve performance by 3.5%, meaning a 10 second 100-meter sprinter could see his time drop by 0.35 seconds, which is a huge time saving relatively speaking. Imagine if Usain Bolt put a pair of these running shoes on."

Samsung Blames Galaxy SIII Burn On "External Energy Source" 169

MojoKid writes "Samsung has some great news for Galaxy SIII smartphone owners. As it turns out, your mobile device isn't at risk of overheating to the point where it catches on fire and burns through its casing, as a forum member at Boards.ie claimed was the case with his Galaxy SIII a couple of weeks ago. [Note: And has since retracted.] Fire Investigations UK (FIUK), an independent third-party organization, assisted Samsung with looking into the matter, and here's what they concluded: 'The energy source responsible for generating the heat has been determined as external to the device... the device was not responsible for the cause of the fire,' FIUK said in a statement. 'The only way it was possible to produce damage similar to the damage recorded within the owner's damaged device was to place the devices or component parts within a domestic microwave.'"

New submitter Doctor_Jest links to a recent I, Cringely column, in which Cringely "is speculating how the world will look when the 'Post-PC' era is in full swing." He makes the case that in just a few upgrade cycles, extensible phones and other devices, coupled with remotely stored data, could replace most of today's conventional PCs — but also admits he thought this transition would have already happened.

fMRI Lets Israeli Student Control Robot In France With His Mind 92

Posted by timothy
from the want-to-do-this-right-now dept.
MrSeb writes "An Israeli student has become the first person to meld his mind and movements with a robot surrogate, or avatar. Situated inside an fMRI scanner in Israel, Tirosh Shapira has controlled a humanoid robot some 2000 kilometers (1250 miles) away, at the Béziers Technology Institute in France, using just his mind. The system must be trained so that a particular "thought" (fMRI blood flow pattern) equates to a certain command. In this case, when Shapira thinks about moving forward or backward, the robot moves forward or backward; when Shapira thinks about moving one of his hands, the robot surrogate turns in that direction. To complete the loop, the robot has a camera on its head, with the image being displayed in front of Shapira. Speaking to New Scientist, it sounds like Shapira really became one with the robot: 'It was mind-blowing. I really felt like I was there, moving around,' he says. 'At one point the connection failed. One of the researchers picked the robot up to see what the problem was and I was like, "Oi, put me down!"'"
