New submitter Ben_R_R writes "The Japan Aerospace Exploration Agency has created a camera that can 'see' radioactive contamination by detecting gamma rays emitted by radioactive cesium and other substances. The camera has been tested in the disaster evacuation zone around Fukushima. The image captures levels of radiation in six different colors and overlays the result over an image captured with a wide angle lens."

silentbrad writes with this excerpt from Boy Genius Report: "Some believe a future full of massive, gesture-controlled computer displays like the ones seen in Twentieth Century Fox's Minority Report are an inevitability, and a prototype PC designed by an intern with the Microsoft Applied Sciences Group may be among the first steps in making that future a reality. Massachusetts Institute of Technology Ph.D student and MIT Media Lab research assistant Jinha Lee recently set out to change the way we interact with desktop computers. While progress has been made with 3D display technology, 3D has not yet proliferated in the personal computing space and Lee wants to change that. The end result of his work is a fascinating desktop computer with a transparent 3D display and a unique gesture-based interface that could change the way we use computers."

You've probably noticed that Slashdot's been running some video lately. There are a lot of interesting people and projects in the world we'd like to present in video form, but some of them are too far away for the corporate overlords to sponsor travel to shoot footage in person. (Another reason my dream of parachuting to McMurdo Station will probably never manifest.) We've been playing around with several things on both the software and hardware side, but in truth, all of them have some flaws — whether it's flaky sound (my experience with the otherwise pleasing RecordMyDesktop on Linux), sometimes garbled picture (Skype, even on seemingly fast network connections), or video quality in general. (Google Hangouts hasn't looked as good as Skype, for instance. And of the webcams built into any of the laptops we've tried, only Apple's were much worth looking at. Logitech's HD webcams seem to be a decent bargain for their quality.) We've got a motley bunch of Linux, OS X, and Windows systems, and can only control what's on our side of the connection: interviewees may have anything from a low-end laptop with a built-in webcam to elaborate conferencing tools — which means the more universal the tools, the better. (There may not be any free, open source, high-quality, cross-platform video conferencing tools with built-in capture and a great UI, but the closer we can get, the better.) With all that in mind, what tools and workflow would you suggest for capturing internet conversations (with video and sound), and why? Approaches that minimize annoyance to the person on the other end of the connection (like the annoyance of signing up for an obscure conferencing system) are especially valuable. We'd like to hear both sides, so please chime in if you've had especially good or bad experiences with capturing remote video like this.

no_such_user writes "It's easy to ignore the controversy surrounding software patents, especially if you don't have the passion for technology which Slashdot readers do. But as Dana Nieder discovered, it's not all about major corporations and obscure patent trolls. Her daughter uses a comparatively inexpensive assistive communication app on their iPad, which is being threatened by the makers of a multi-thousand-dollar hardware device."

An anonymous reader writes with a snippet from Hack a Day: "Clap On! Clap Off! was super awesome when The Clapper came out in the mid-eighties. Now [Mathieu Stephan] is trying to make the concept much more functional. He put together a controller that lets you knock on walls to control things around the house. It's called the Toktoktok project and uses small boxes to receive user input and control items like lamps and computers." As the project website points out, Stephan is keeping the project intentionally open.

waderoush writes "The venture backers behind Lytro, the Silicon Valley startup that just released its new light field camera, say the device will upend consumer photography the way the iPhone upended the mobile business. This review takes that assertion at face value, enumerating the features that made the iPhone an overnight success and asking whether the Lytro camera and its refocusable 'living pictures' offer consumers an equivalent set of advantages. The verdict: not yet. But while the first Lytro model may not an overnight success, light field cameras and refocusable images are just the first taste of a revolution in computational photography that's going to change the way consumers think about pictures."

THE_WELL_HUNG_OYSTER writes "Over the years, I've had numerous scanners equipped with automatic document feeders — and all of them jam or grab multiple pages at a time (thereby missing pages). Like you, I've got years of tax returns and legal documents to scan, but with these kinds of barriers, it would take months to scan everything. Enterprise-grade machines cost 5 figures. How do Slashdotters become paper-free?"

An anonymous reader writes "Doug Engelbart should be known to everyone on Slashdot — he did invent the mouse after all, among many other inventions all of us rely on today. There was one more obscure device he came up with that never really took off, though. It was called the Chorded Keyboard, and consisted of a system that allowed you to type using just one hand. The key to this system was finger combinations, which allowed up to 32 different characters — more than enough for the alphabet. Now that one-handed keyboard has been ported to work with touchscreens, and it could end up being quite popular. The key benefit is the fact you can type anywhere on the screen and don't even need to see where you are typing. The only difficulty is learning all the key combos, but once you have them cold you may be able to type faster than with two hands on your smartphone or tablet." Bonus: being software-only and open-source, it's much cheaper than a Twiddler.

nk497 writes "Microsoft has released Kinect for Windows, featuring a new "near mode" that lets the gesture control tech be used as close as 40cm. The Kinect for Windows hardware will retail at $249 — well above the price of the version for Xbox 360 consoles. Microsoft defended the price difference, saying sales of games and Xbox Live subscriptions help subsidize the console version. The new version will support Windows 7 and the Windows 8 developer preview, as well as Windows Embedded 7 devices."

mikejuk writes "Evi, a new rival to Siri, Apple's voice-driven personal assistant, has made its debut on both the iPhone and Android. And people are so keen to that Evi's servers are overloaded — so be prepared for a wait for answers." The app costs 99 cents for iOS users, but it's free on Android.

An anonymous reader writes to point out reports that Asus is "working on a new laptop that will include Kinect gestures and will be compatible with Windows 8," and adds, "What does this mean for the consumer? Portable gestures in Windows 8!" Wired has an article based on the same report, which mentions also the prospect of devices incorporating alternative gesture-tracking software from SoftKinectic and others.

Frankie70 writes "'Siri's dirty little secret is that she's a bandwidth guzzler, the digital equivalent of a 10-miles-per-gallon Hummer H1.' A study by Arieso shows that users of the iPhone 4S demand three times as much data as iPhone 3G users and twice as much as iPhone 4 users, who were identified as the most demanding in a 2010 study. 'In all, Arieso says that the Siri-equipped iPhone 4S "appears to unleash data consumption behaviors that have no precedent."'"

New submitter DeanCubed writes "In a Nintendo investor meeting, CEO Satoru Iwata confirmed a new Nintendo Network for the company's 3DS and upcoming Wii U game systems. This includes multiple user accounts per console (not tied to hardware, a first for Nintendo) and digitally distributed retail software releases for their online store. Iwata also noted that the Wii U's tablet controller will feature NFC (Near Field Communication) functionality, allowing the ability to use figurines and cards to input visual data to the console. They are hoping to use this to make micro-transactions for paid DLC easier."

An anonymous reader writes "A guy who goes by the online handle DDRBoxman decided it would be fun to blow up his Samsung Galaxy Nexus display onto the wall by connecting his phone to a projector. He then connected the whole thing to a PC and, thanks to Microsoft's open-source Kinect platform for Windows, he was able to create a custom ROM that mapped out the phone interface to the Kinect sensors. Pretty neat!"

For the first few years of its existence, it would have been fair to say that Canonical was essentially polishing, packaging and publishing Debian Linux (and Gnome) to create the base Ubuntu desktop, to great acclaim. For the past few years, though, the company has pushed new looks and new applications (cf. Unity and Ubuntu TV), and refused to stick with prettifying existing interfaces. Now, Barence writes with this excerpt from PC Pro: "Ubuntu is set to replace the 30-year-old computer menu system with a 'Head-Up Display' that allows users to simply type or speak menu commands. Instead of hunting through drop-down menus to find application commands, Ubuntu's Head-Up Display lets users type what they want to do into a search box. The system suggests possible commands as the user begins typing – entering 'Rad' would bring up the Radial blur command in the GIMP art package, for example. HUD also uses fuzzy matching and learns from past searches to ensure the correct commands are offered to users. Canonical's Mark Shuttleworth told PC Pro the HUD will make it easier for people to learn new software packages, and migrate from Windows to Linux software without having to relearn menus. The HUD will first appear in Ubuntu 12.04."

MrSeb writes "Researchers from Imperial College London and A*STAR in Singapore have shown off a terahertz antenna that's just 100 nanometers across — about 30,000 times smaller than existing terahertz antennae — and two orders of magnitude stronger than other T-ray beam-forming techniques. T-rays are a lot like EHF (extremely high frequency), which is used by millimeter wave scanners in airports, medical imaging, and emerging wireless networking standards like WiGig — but stronger, faster, and more detailed. Where EHF radiation can see through your clothes, T-rays can penetrate a few millimeters of skin. Furthermore, because atoms and molecules have a unique terahertz-range signature, T-ray scanners can detect toxic substances, bombs, drugs — or even cancerous tumors under your skin. Most importantly, though, due to the nano scale of these antennae, it's possible to create huge antennae arrays on a single silicon chip, meaning hand-held T-ray scanners are now a possibility. In the not so distant future, every household might have a Star Trek-like tricorder capable of detecting cancer or other diseases."

snydeq writes "Dr. Franklin Tessler discusses the hidden stress-related injuries of touchscreen use, and how best to use smartphones, tablets, and touch PCs to avoid them. 'Touchscreen-oriented health hazards are even more insidious because most people aren't even aware that they exist. The potential for injury from using touchscreens will only go up ... as the rise of the touchscreen means both new kinds of health hazards and more usage in risky scenarios,' Tessler writes, providing tips for properly positioning touchscreens and ways to avoid repetitive stress injuries and eyestrain."

clinko writes "Microsoft has announced that the new Kinect for Windows hardware and accompanying software will be available on February 1st, 2012 in 12 countries, at a suggested retail price of US $249 ($149 for edu). Microsoft has chosen a hardware-only business model for Kinect for Windows; they will not be charging for the SDK or the runtime. These will be available free to developers and end-users respectively."

jehan60188 writes "I want a camera that's better than my phone, but I don't have the technical knowledge to fully appreciate a DSLR. I think the MILC style will be a happy compromise, but I'm concerned that it might be all 'marketing' and no 'technology.' I don't have a lot of demands, but I do like taking macro shots of things from time to time. Also, my sister is going to China in a few months, so a telephoto lens would probably be good for sight seeing (since I could employ optical zoom instead of the imaginary 'digital zoom')."

An anonymous reader writes "I'm trying to help a school put their classes online in the way most minimally invasive to the teachers. A few environmental considerations: They don't always have live internet in the classroom, or I'd just run to Skype. I'm hoping to make it as much one-touch start/stop as possible to start recording, stop recording, and upload to a server. I'd like to believe others here have already done something similar, so if a package or process worked for you, that would be great to hear. Not sure what if it's all PowerPoint lectures, or if they actually use a whiteboard, and if so what the best camera would be to use (on a school budget!)."
