    When Xiaomi introduced its Black Shark 2 gaming phone a year ago, it hyped up the pressure-sensitive display that lets users map left and right controls to the screen. The new Black Shark 3 Pro takes things off the screen with physical pop-up shoulder buttons. In game mode, users can choose to use the two, 21-millimeter-wide buttons that raise 1.5 millimeters from the body of the phone. The buttons can supposedly withstand over 300,000 lifts and more than one million clicks.

    At Nintendo's Switch press conference today, the company revealed that its upcoming gaming console will have -- wait for it -- a capacitive touch screen. This is a pretty big move for Nintendo, which has traditionally gone with resistive touch displays -- the DS, the 3DS and the Wii U all had resistive touch screens and had to be used with a modicum of finger strength or a stylus. Resistive touch screens are typically not as finger-friendly as capacitive displays that are widely used in smartphones and tablets today. Capacitive screens also allow for multitouch gestures, which is lacking on resistive models. It's a small difference, perhaps, but it's a move that makes the Switch that much more enticing to a modern audience. Click here to catch up on the latest news from Nintendo's Switch event.

    Makey Makey Go is a super-cheap invention kit. For $19, you get a USB stick and an alligator clip; use the two in tandem and you can turn (almost) anything into a keyboard or mouse button. Examples of potential uses include a Slip'N Slide that takes a photo as you zoom past, a donut spacebar, a dog bed that initiates a Skype call and a foil sword game that counts the number of times you hit an opponent. If you have an idea that requires more than one button, you just plug in another stick.

    It hasn't been all that easy to make your own touchscreen-friendly gloves short of grabbing a needle and some conductive thread. With Tony Yu's upcoming Nanotips, however, it could be as simple as applying touch-up paint. The conductive liquid gives any pair of gloves (and many other surfaces) the same capacitive effect as your own fingers, letting you use your phone no matter what style of handwear you prefer -- you can check email while you're still dressed for a motorcycle ride. If you're intrigued by the idea, you can pledge $22 Canadian ($20 US) to get a bottle of Nanotips Black, which is intended for rubber and other thicker materials. Outside of early bird specials, it costs $30 CAD ($27 US) to get the fabric-oriented Nanotips Blue. Both formulas should reach backers between February and March.

  • Sony patent claims touch force detection via microphone

    In the annals of "clever patents that may never amount to anything," we now have an entry from Sony: a method of sensing touch strength with sound. Since capacitive touchscreens can't detect pressure on their own, a second film is needed that can add weight and cost. Sony's freshly granted patent claims that a microphone can take on that job instead by listening to the sound your finger or stylus makes when it hits the screen and deducing force from that. It could also be used with a camera-based position detection system as shown above, meaning your finger's location and force could be calculated on a non-active surface like an ordinary table. Obviously such a device would only detect taps, not presses, and Sony has claimed a calibration method that the average user may not want to bother with. It probably seemed like a good idea at the time of filing (2009) when other force-sensing options had yet to hit market, but this one seems unlikely to see daylight -- though, you never know.

  • Apple patent would have devices sense a squeeze through metal

    Apple likes to build devices using metal. Unfortunately, the material isn't usually conducive to touch, in the literal sense of the word -- capacitive touch doesn't always register on a metal gadget, and you can often forget about a response to pressure. A newly published patent from the company could at last get these unfeeling devices to acknowledge our grip without putting sensors above the surface. Apple's method would detect the changes in capacitance between hidden nodes when a device's shell is put under strain, and trigger a hardware or software reaction when there's a strong-enough squeeze. The concept is simple enough. Just what Apple would like to do with the patent, if anything, is the real riddle. The patent was originally filed in 2009, and covers just about everything computer- or mobile-based that Apple could produce; any burning desire to use the technique would likely have been satisfied by now. If our future iPhones or Macs ever answer a hug with more than just cold indifference, though, we'll know why.

    Atmel's XSense technology made its debut way back in April of 2012, but today ASUS became the first big name gadget maker to commit to using the tech -- pledging to put it in an unnamed next-gen tablet set to debut in Q1 of this year. For those unfamiliar, XSense is a capacitive touch sensor that can be bent and bonded to surfaces of any shape. We got to see XSense for ourselves at CES today and chat with its makers to learn a little more about it. While there are no technical limitations to the size of its touch sensors, Atmel's technology is currently limited to a max size of 32 inches due to manufacturing constraints. However, the company has plans to increase that fabrication size at its Colorado manufacturing facilities. We got to test out the technology on a piece of Corning Gorilla Glass bonded imbued with XSense (alas, no ASUS tablet sneak peeks to be had), and can confirm that the technology does work quite well. The company sees its touch sensor as a way for device makers to utilize currently unused edge real estate on phones and tablets, in addition to providing designers with more flexibility when creating gadgets. Of course, we'll have to see what kind of creative ways ASUS and other OEMs implement XSense, but you can see some shots of the sensor film and Atmel's demo unit in our gallery below.

    Sometimes the plays on words are unavoidable -- in fact, they form the very heart of Scott Garner's recent musical creation. His BeetBox turns six of its namesake root vegetables into drum pads through SparkFun capacitive touch sensors, all of which are controlled by (what else?) a Raspberry Pi. Cleverness goes beyond the core technology and food jokes, as well. All of the circuitry and audio equipment is hidden within the wood box, making it look more like a horticultural project than machinery. We don't mind the lack of production plans when there's source code available; we're mostly curious as to what in our garden would make for a good rhythm section.

  • Disney Research develops capacitive touch that detects multiple users through their fingertips (video)

    Creating a truly multi-user, multi-touch display is a tricky prospect. How do you know who's who short of turning the screen into one giant fingerprint reader? Chris Harrison, Ivan Poupyrev and Munehiko Sato at Disney Research have suggested in a paper that fingerprinting on a capacitive touchscreen isn't far off -- it's just what we need to fingerprint that matters. Rather than look for physical ridges, the scientists' method sweeps through AC frequencies to find the exact electrical impedances of fingertips in contact with the screen. Different bodies, different clothes and even different shoes give everyone a unique signature that lets the screen identify specific people, even when they each have multiple fingers in play. The researchers propose that the technique would work well in collaborative workspaces, personalized devices and security, but let's not forget that this is Disney we're talking about: it's placing a strong emphasis on the prospects for shared screen gaming without the limitations we know today. While any practical use is still some distance away, it's easy to see future tablets and tables that are designed from the start to encourage a little socializing.

  • Disney Research's Botanicus Interacticus adds capacitive touch to ordinary plants, we go hands-on

    Sure, you spend plenty of time talking to your plants, but have you ever made them sing? In partnership with Berlin-based Studio NAND, Walt Disney's experience development arm, coined Disney Research, has found a way to take human-plant interaction to an almost freakish level. The project's called Botanicus Interacticus, and centers around a custom-built capacitive sensor module, which pipes a very low current through an otherwise ordinary plant, then senses when and where you touch. Assuming your body is grounded, the device uses more than 200 frequencies to determine exactly where you've grabbed hold of a stem. Then, depending on how it may be programed, the sensor can trigger any combination of feedback, ranging from a notification that your child is attempting to climb that massive oak in the yard again, to an interactive melody that varies based on where your hand falls along the plant. Because this is Disney Research, the company would most likely use the new tech in an interactive theme park attraction, though there's currently no plan to do much more than demo Botanicus Interacticus for SIGGRAPH attendees. This week's demonstration is giving the creators an opportunity to gather feedback as they try out their project on the general public. There's four different stations on hand, ranging from a stick of bamboo that offers the full gamut of sensitivity, including the exact location of touch, to an orchid that can sense an electric field disruption even as you approach for contact. While interactive plants may not have a role in everyday life, Botanicus Interacticus is certainly a clever implementation of capacitive touch.

    Parents who've already purchased Archos' 7-inch Child Pad may be feeling somewhat miffed, as its screen's been upgraded from resistive to capacitive just two months after launch. There's no such thing as free multi-touch, so you'll have to fork out another ten bucks on top of the original asking price for the new version of the ICS slate, bringing the total to a cent under $140. Other internals are identical, so customers can still expect a 1GHz ARM processor, 1GB of RAM and 4GB of expandable storage, with some exclusive chipmunk-based content to boot. Just remember to let the kids have a go once in a while.

  • Samsung files a patent for a capacitive stylus with NFC and headset, your next C-Pen may get talkative

    Samsung is clearly big on pens. It's no shock, then, that we now know the company applied for a patent on a new stylus while the original Galaxy Note was still fresh out of the box. The capacitive pen of Samsung's dreams includes its own wireless headset in the clip to make voice calls without having to buy a separate earpiece -- something that we've only seen recently in the real world. It would even find room for NFC to pair the pen up with a host device using a minimum of fuss. The most appealing part of the patent may be its pragmatism. Unlike some of the flight-of-fancy patents we've noticed lately, the technology in the new stylus is well within reach. No patent is ever a surefire sign of action, but it's no great leap in logic to see a follow-up to the C-Pen or S Pen letting us call for pizza in between drawing sessions.

    If you're tired of bananaphones that just make calls, the crew at Gadget Gangster now has a homebrew project to use them for musical escapades. A custom-coded (and appropriately named) Adafruit Propeller board turns a bunch of bananas into the Bananaphone TouchSynth, a synthesizer using the same capacitive touch principles that let a MaKey MaKey turn anything into a controller. The project as it's built won't be rocking stadium-sized crowds anytime soon -- not with those beeps and that lone speaker -- but there's nothing stopping it from scaling up to bigger sounds. Just remember that your fresh beats will turn very brown within a few days.

  • Droplet and StackAR bring physical interface to virtual experiences, communicate through light (hands-on)

    Light-based communication seems to wind throughout the MIT Media Lab -- it is a universal language, after all, since many devices output light, be it with a dedicated LED or a standard LCD, and have the capacity to view and interpret it. One such device, coined Droplet, essentially redirects light from one source to another, while also serving as a physical interface for tablet-based tasks. Rob Hemsley, a research assistant at the Media Lab, was on hand to demonstrate two of his projects. Droplet is a compact self-contained module with an integrated RGB LED, a photodiode and a CR1216 lithium coin battery -- which provides roughly one day of power in the gadget's current early prototype status. Today's demo used a computer-connected HDTV and a capacitive-touch-enabled tablet. Using the TV to pull up a custom Google Calendar module, Hemsley held the Droplet up to a defined area on the display, which then output a series of colors, transmitting data to the module. Then, that data was pushed to a tablet after placing the Droplet on the display, pulling up the same calendar appointment and providing a physical interface for adjusting the date and time, which is retained in the cloud and the module itself, which also outputs pulsing light as it counts down to the appointment time. StackAR, the second project, functions in much the same way, but instead of outputting a countdown indicator, it displays schematics for a LilyPad Arduino when placed on the tablet, identifying connectors based on a pre-selected program. The capacitive display can recognize orientation, letting you drop the controller in any position throughout the surface, then outputting a map to match. Like the Droplet, StackAR can also recognize light input, even letting you program the Arduino directly from the tablet by outputting light, effectively simplifying the interface creation process even further. You can also add software control to the board, which will work in conjunction with the hardware, bringing universal control interfaces to the otherwise space-limited Arduino. Both projects appear to have incredible potential, but they're clearly not ready for production just yet. For now, you can get a better feel for Droplet and StackAR in our hands-on video just past the break.

  • Intel Ivy Bridge touchscreen Ultrabook reference design hands-on (video)

    Interested in replacing both your tablet and that clunky notebook with a svelte all-in-one portable? Intel might have just the gadget for you -- an Ivy Bridge Ultrabook with a built-in 13.3-inch 1600 x 900-pixel capacitive-touch LCD. We happened upon such a device in the bowels of Intel's gaming-centric CeBIT booth, and had a chance to go hands-on with the company's one and only (at this show, at least) reference design touchscreen Ultrabook. The device we saw appeared to be no larger or thicker than similar portables, but integrated a gorgeous 13.3-inch touchscreen, along with that elusive 1.5GHz Ivy Bridge processor. Unfortunately Intel was mum on detailed specs, though the prototype we saw did include a pair of USB 3.0 ports, SIM and SD card slots, and an HDMI port. And according to the system info page, the touch feature supports up to 10 individual input points. We're also told that there might be NFC functionality on-board, though the only visible confirmation of this hardware feature was a piece of medical tape with the letters "NFC" inscribed.The touch functionality worked just as expected -- if you've used touch on a high-end tablet before, you're already familiar with the experience here. We were able to navigate the installed Zinio app with ease, flicking through magazine pages and pinch-and-zooming our way around a cover. You can of course use the touchscreen to adjust system settings, drag-and-drop files or input text with the on-screen keyboard, though we found the trackpad and hardware keyboard to be more practical here. Overall, this appears to be a no-compromise solution -- it will surely add to the manufacturing cost for next-gen Ultrabooks, but if you opt for a touch-equipped model only to find that you prefer traditional input controls, there's not much lost on the feature front. And, if you do happen to enjoy flicking your way around a notebook, you're definitely in for a treat. You'll find our hands-on video just past the break.

    We don't have 100 fingers -- theoretically the supported limit of Windows 8 on the 82-inch capacitive touchscreen display we just had a chance to go hands-on with at the company's latest OS demo at Mobile World Congress -- but things looked pretty impressive even with just 10. The display we saw is manufactured by a company called Perceptive Pixel, and it may even look familiar -- it's the same glass screen used by television news networks like CNN. But, unlike the giant touchscreens you've seen on TV, this guy is connected to a standard off-the-shelf PC running Windows 8 Consumer Preview. The glass panel is constructed of optically-bonded Gorilla Glass, so there's very little space between the picture and your hand, making for a much more realistic user experience. Naturally, this monitor is all about the visuals, so you really need to see it in action to get an accurate impression of just how slick the experience can be. Jump past the break for our hands-on.

    Synaptics, Atmel,N-trig, Raydium, Cypress and Focaltech -- big names in the field of touch-based devices -- have all agreed get on board with NVIDIA's DirectTouch platform. The tech offloads some of the work needed to track and process finger input from the controller to the Tegra 3, improving response and battery life. We were first introduced to the architecture at CES, but wasn't clear that others would embrace it. With two of the biggest makers of touchscreen controllers, Synaptics and Atmel, throwing their weight behind the project, though, things are looking up for NVIDIA-powered tablets. N-trig is even leveraging the processing power to improve the response of capacitive styli by combining DirectTouch with DuoSense (the tech behind the HTC Flyer).

    Look, we recognize that touchscreens have come a long way in the last few years, but there's always room for improvement. Thankfully, Synaptics agrees and is rolling out an update to its ClearPad capacitive panels. At the heart of the improved system is a technology called SignalClarity, which boosts signal-to-noise ratio for better accuracy and finger separation. The new tech will not only lead to a better touchscreen experience, but it could also help drive down costs since manufacturers would be free to use lower cost components that might normally interfere with a capacitive panel. It'll be a little bit before the next-gen ClearPad makes is debut in a consumer product and chances are you won't see Synaptic brand emblazoned across the packaging of your next smartphone. That's ok though, we know it's in there working hard to keep our fingers happy. Check out the PR after the break for more details.

  • Get diagnosed by spitting on an iPhone, social graces terminal

    Korean scientists reckon that the capacitive touchscreens on our phones and tablets could help diagnose diseases from what's floating around in your mouth. It works through the screen's ability to detect minute capacitive differences in disease-carrying liquids placed on its surface. Experiments by Hyun Gyu Park and Byoung Yeon Won at the Korea Advanced Institute for Science and Technology in Daejeon managed to detect chlamydia microbes in three different concentrations. Once again, the iPhone acted as medical chief, although the setup isn't yet able to distinguish between different bugs. There are also teething troubles with the touchscreen, as capacitive read-outs can be affected by moisture and sweat that are on the screen alongside your 'sample.' One solution to this would be to create a disposable film that attaches to the iPhone surface. There's a second reason for this, as Park diplomatically puts it: "Nobody wants direct application of bio-samples onto their phone." Let's hope Siri doesn't take it personally.
