michael_cain writes "I've been asked (by family, friends) to consider several small embedded controller projects. A good starting point for all of them would be a backlit LCD graphics module with touch screen pre-mounted in a plastic enclosure with enough room behind the display for a custom circuit board. 320-by-240 pixels, 3.5 to 4.5 inch diagonal measure, monochrome is sufficient (but color is always cool), easily driven by an AVR or PIC type microcontroller. And priced at a reasonable point for a hobbyist! Anyone seen anything like this?"

squiggleslash writes "CNN reports that IBM CEO Jeanette Horan has banned Siri, the iPhone voice recognition system. Why? According to Horan '(IBM) worries that the spoken queries might be stored somewhere.' Siri's backend is a set of Apple-owned servers in North Carolina, and all spoken queries are sent to those servers to be converted to text, parsed, and interpreted. While Siri wouldn't work unless that processing was done, the centralization and cloud based nature of Siri makes it an obvious security hole."

colinneagle writes with an excerpt from Network World: "Guy's and St Thomas' Hospital in London began trials of a Kinect-driven camera last week that would sense body position, and by waving his or her hands, the surgeon can sift through medical images, such as CT scans or real-time X-rays, while in the middle of an operation. During surgery, a surgeon will stop and consult medical images anywhere from once an hour to every few minutes. So the surgeon doesn't have to leave the table, the doctor will work with assistants, but sometimes, if you want things done to your satisfaction, you have to do it yourself. Dr. Tom Carrell, a consultant vascular surgeon at Guy's and St Thomas', described an operation on a patient's aorta earlier this month to New Scientist. 'Up until now, I'd been calling out across the room to one of our technical assistants, asking them to manipulate the image, rotate one way, rotate the other, pan up, pan down, zoom in, zoom out.' With the Kinect, he says, 'I had very intuitive control.'"

An anonymous reader writes "Researchers Jon Moeller, Andruid Kerne, and a team from the Interface Ecology Lab at Texas A&M University showcased the latest ZeroTouch multi-finger sensing technology at ACM CHI, in Austin. ZeroTouch is a new spin on infrared sensing technology, which optimizes the sensor readout cycle for a linear array of modulated infrared light receivers. ZeroTouch also constitutes a precise free-air sensing technology (Kinect can be used as a complementary technology to sense depth). Researcher Bill Hamilton uses ZeroTouch integrated with Wacom Cintiq to showcase new embodied eSports interaction (video) for the open source Zero-K real time strategy game."

New submitter mmmmdave writes "My parents love to Skype with my kid. My kid loves to mash laptop buttons and drool on the screen. And because we don't want to spend forty minutes every night holding the laptop outside of baby arms' length, we're looking to build some sort of wall-mounted monitor + webcam thingy. I'm sure there's a much cheaper option than sticking an iPad on the wall; what's more, non-touchscreen is probably better, so my daughter can't hang up the calls. Any ideas?"

dartttt writes "Florian Echtler has developed an open-source driver for the Microsoft Surface 2.0 touch screen. According to him, the open source implementation works surprisingly well on Ubuntu 11.10. The process requires you to boot Linux on your Surface 2.0 in the first place. However, it can be done by just booting Ubuntu from a USB hard disk without modify anything on the original Win7 installation."

surewouldoutlaw writes "Remember that scene in Fantasia where Mickey turns all the brooms into an army of workers? Well, Disney isn't quite there, yet. But scientists with the company's research lab at Carnegie Mellon University in Pittsburgh have been able to turn virtually any surface, including liquid water and the human body, into a multi-touch interface. The new system is called Touché, and it is as awesome as it sounds."

MrSeb writes "Microsoft Research, working with the University of Washington, has developed a Kinect-like system that uses your computer's built-in microphone and speakers to provide object detection and gesture recognition, much in the same way that a submarine uses sonar. Called SoundWave, the new technology uses the Doppler effect to detect any movements and gestures in the proximity of a computer. In the case of SoundWave, your computer's built-in speaker is used to emit ultrasonic (18-22KHz) sound waves, which change frequency depending on where your hand (or body) is in relation to the computer. This change in frequency is measured by your computer's built-in microphone, and then some fairly complex software works out your motion/gesture. The obvious advantage of SoundWave over a product like Kinect is that it uses existing, commodity hardware; it could effectively equip every modern laptop with a gesture-sensing interface. The Microsoft Research team is reporting a 90-100% accuracy rate for SoundWave, even in noisy environments."

New submitter brabq writes "Now that I have a couple of CableCard tuner devices in the house (including the network-based HDHomeRun Prime), I'm thinking of buying one of those all-in-one touchscreen PCs for our kitchen (yeah, something I've always sworn against for future repair reasons). The idea is that it would be used primarily for (1) watching TV, via the aforementioned Prime and WMC, and (2) light web surfing (recipes, some sort of video chat possibly). Does anyone have any experience with these types of devices in a kitchen-like setting (where I'd like to use a touchscreen over having a keyboard/mouse on a kitchen counter)? I keep hearing that Windows 8 is going to have some added benefits to this type of setup — is it worth waiting for its release? My end goal is it has to have a high WAF ... if my wife doesn't like its appearance on the counter or finds it useless, then the whole thing will be a waste."

jjp9999 writes "Bethesda announced they're bringing Kinect support to Skyrim. It doesn't sound like this will include motion detection. Rather, it will be around voice commands — tons of voice commands. It supports dragon shouts, trading, navigation, switching weapons, and a whole lot of other features that usually require you to assign hotkeys or to sort through menus. They also gave a brief hint at new content, stating they've 'been hard at work on creating the first set of game add-ons that will be exclusive to the Xbox 360. This additional content will add new quests, locations, features, and much more to the world of Skyrim.'"

lightbox32 writes "Samsung has finally responded to an article recently published by HD Guru titled 'Is your TV watching you?' [See this related Slashdot post] which discussed the fact that new features in Samsung's top 2012 models — including built-in microphones, HDTV camera, wireless and wired Internet connection, built-in browser with voice to text conversion, face recognition and more — could be used to collect unprecedented personal information and invade our privacy. Samsung has now provided their privacy policy, which may or may not lay the issue to rest." I vote for "not" — conspiracy theories about mandatory (or just secret) surveillance equipment in consumer electronics is just too persistent, even when the technical capabilities turn out to be a hoax; when the equipment is actually all in place and the user is protected only by a corporate honor policy, it's hard to be sanguine. (I recall there was a much rumored secret capability for law enforcement agencies to secretly and remotely turn on the internal microphones in PCs meeting the PC 97 spec, and this was an integral part of the plan. Since the government insists that telecom equipment have built-in backdoors, why should that sound all that crazy?)

Malvineous writes "Don't have $1500 to drop on a USRP? A Linux kernel developer has discovered that a Realtek digital TV tuner chip has an undocumented mode that turns it into a software-defined radio, with a frequency range of 64-1700MHz. The going rate for one of these USB devices can be as low as US$11. If you're unfamiliar with software-defined radio and have 20 minutes to spare, Balint Seeber has a great video introduction."

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.
