Somewhere in an underground ice lair, Jack Frost’s prepping to nip at noses and keep covered hands from touch devices. But SMK Corp’s got a capacitive solution set to thwart old man winter’s digitus interruptus. On display at this year’s FPD International in Japan, the company’s touchscreen innovation incorporates a specialized chip capable of highly-sensitive pressure detection that works in conjunction with a noise-filtering sensor to make your gloved gestures readable. It’s good news for those of us subject to occasional bouts of frostbitten weather, but don’t clap just yet — these panels will initially be headed to in-car navigation systems. Still, with the displays workable on screens up to 8-inches in size, it’s possible we could be seeing this tech extend to smartphones in the near future. So, there’s a remedy out there folks, but while you wait for it, it’s best to keep those glittens close at hand.

We’re used to tapping away at flat, glass-covered touchscreen devices like smartphones and tablets. A group of Stanford researchers have taken that capacitive touch concept and applied it to a completely new form factor, which could have wide-ranging applications in consumer technology, robotics and beyond.
The team created a transparent, super-stretchy sensor that can be used repeatedly without getting deformed, snapping back into shape after each use. The team hopes that their sensor could be used in medical applications like pressure-sensitive bandages, or even as an outer, skin-like layer to create touch-sensitive limbs or robots. Of course, it could also be used on touchscreen devices and computers.
Through spraying carbon nanotubes onto a layer of silicon and then stretching out the substance a few times, the nanotubes are essentially organized into “springs.” The “springs” can stretch in any direction, and be used to measure the force exerted upon itself over and over again without getting stretched out of shape.
The capacitive touch sensor works like this: There are two conductive parallel plates. When one or both are pressed, the distance between them gets smaller, increasing the capacitance of the sensor. That increase can be quantified and measured. In this case, the two conductive parallel plates facing one another are composed of nanotube coated-silicon, with a middle layer of silicon that stores charge.
The stretchy sensor can detect a wide array of touches, according to Darren Lipomi, a postdoctoral researcher on the team. That means from something as light as a “firm pinch between your thumb and forefinger” to double the pressure of a stamp of an elephant’s meaty foot.
So far the sensor isn’t as sensitive as previous projects the Stanford team has worked on (one of which was so responsive that the pressure exerted from a 20 milligram bluebottle fly carcass was well above what it could detect). However, the researchers can eventually use those previous techniques to calibrate this stretchy capacitive sensor. “We just need to make some modifications to the surface of the electrode so that we can have that same sensitivity,” said Zhenan Bao, associate professor of chemical engineering at Stanford.

Is it more gauche to pull out your phone in the middle of a date, or to draw a bunch of crop circles on your pants? That’s the question we were asking ourselves after coming across PocketTouch — a new Microsoft Research prototype that lets you manipulate your handset without ever removing it from your pocket. Developed by researchers Scott Saponas, Chris Harrison and Hrvoje Benko, the device essentially consists of a customized, multitouch capacitive sensor hooked on to the back of a smartphone. This sensor is capable of picking up gestures through fabric, allowing users to execute a wide array of eyes-free, gesture-based functions (including simple swipes and alphanumeric text) without ever having to actually whip out their phones. To do this, the team implemented what it calls an “orientation-defining unlock gesture,” which helps the prototype get its bearings, before testing the capacitive sensors across different fabrics. According to Microsoft, the outcome “exceeded expectations,” though there’s no word on when or if this Goliath of a device could ever hit the mainstream.

The GPS gurus over at Garmin have just launched the aera 796 and 795 — a pair of new navigation devices designed specifically for pilots who don’t enjoy getting lost. As the flagship member of the aera family, the 796 sports a seven-inch, 480 x 800 capacitive touchscreen (capable of displaying maps in either landscape or portrait mode) and features Garmin’s 3D Vision technology, providing users with a behind-the-plane view of the terrain below, including rivers, landing strips or any other obstacles. This knee-mounted co-pilot can also serve as an electronic flight bag, allowing captains to digitally store flight routes and airport diagrams directly on their devices. Plus, if it’s hooked up to a compatible GPS system, the 796 can provide real-time traffic updates, while streaming SiriusXM radio straight to the cockpit (the North America-specific 795 features identical specs, minus XM compatibility). Aviation enthusiasts can buy the 796 and 795 for the respective prices of $2,500 and $2,200, at the source link below. Full PR after the break.
Multitasking business executives are going to love this. Whether you’re taking notes on your tablet, pointing out graphs in a presentation or just signing reports, Griffin’s new “Stylus + Pen + Laser Pointer” should have you covered. As the name implies, it’s a three-in-one input device containing a red laser pointer, an “omni-directional” capacitive stylus and a refillable ball point pen. It certainly seems convenient, but with a $50 price tag you may want to think twice before ditching your Bic. Full PR past the break.
There’s nothing all that exciting about most point-and-shoot cameras. You point, they shoot, end of story. But Samsung has been shaking things up as of late. First, the TL220 and TL225 added a second, 1.5-inch LCD to the front of the camera, making up the company’s 2009 lineup of DualView cams. We’ve never actually seen anyone using them on the street, but Samsung reps insist that they’ve been an absolute hit. Well alright then. This year, CES brought the company’s remote-shooting-enabled SH100, which lets you use a Samsung-branded Android smartphone to frame, zoom, and capture images over WiFi. A rather obnoxious delay doesn’t make this a blockbuster feature, but still, this is pretty imaginative stuff.
Now this week at IFA, the company just introduced yet another completely original (and practical) camera design with its MV800. The camera’s image quality isn’t much to speak of (though we’ve only had a chance to use a pre-production model), but its MultiView flip-up LCD is pretty darn fantastic — in concept, at least. The 16.1 megapixel cam’s entire 3-inch capacitive touchscreen flips from flush with the rear up to a 180-degree angle (and anything in between), making it possible to not only shoot perfectly framed self-portraits, but also to have a direct view of the display when shooting both below, and above eye level. We love to see manufacturers continue to push the envelope when it comes to innovation, but how did the $279 MV800 perform overall? Jump past the break for our impressions.
Monza. It’s a beautiful part of Italy, a majestic park split by one of the most historic racetracks in the world, and it was also the codename for this rather more homely looking phone. This is a handset that would go on to be known by many names (Storm 3, Touch…) before receiving its final moniker: Torch 9850. Why all the pseudonyms, and why choose to confusingly overlap this with the somewhat similar but rather different Torch 9810 that’s also officially launching today?
Maybe RIM didn’t know what to make of this keyboard-free phone. Maybe the company wanted to distance itself from the Storm. Or, maybe what we have here is a smartphone that’s trying to find an identity by sadly ditching the feature that, for many, makes a BlackBerry a BlackBerry: the physical keyboard. How does this smoothie compare to the others, and is it worth sacrificing all the QWERTY wonder found within the 9810? Read on to find out.
This just in: people really like touchscreens, and their tastes aren’t going to change anytime soon. That’s the takeaway from a new report from market research firm DisplaySearch, which predicts that revenue from touch panel sales will hit the $13.4 billion mark by the end of this year, before soaring to nearly $24 billion by 2017. Shipments of capacitive touch displays, in particular, are expected to increase by 100-percent over last year, accounting for a full 70-percent of all tactile revenues. The mobile market still accounts for most of this industry-wide growth, but demand for touch-based tablets is accelerating considerably, with more than 72 million panels expected to ship this year, and 100 million projected in 2012. Jonesing for more numbers? Better gallop past the break to get your hands on the full PR.
Just a few weeks after unveiling its ZMS-20 and ZMS-40 StemCell processors, ZiiLabs has now designed a new family of slates to house them. Developed with the OEM market in mind, the company’s new Jaguar Honeycomb tablets come in two breeds — one with a seven-inch, 1024×600 LCD and another with a ten-inch 1280×800 display. Unlike their ZiiO predecessors, these 64GB siamese twins call for both capacitive and resistive touchscreen capabilities, support OpenGL ES 2.0 3D graphics and, as you can see in the image above, feature front- and rear-facing five-megapixel cameras. And, of course, there’s a dual-core ARM Cortex-A9 ZMS-20 or quad-core ZMS-40 helping them purr right along, both clocking in at 1.5 GHz. The two Jaguars will be uncaged at next week’s Computex tradeshow in Taiwan, but you can find more information in the PR that awaits you after the break.
Samsung’s Super AMOLED may have beat Toshiba to the in-cell capacitive touch punch, but we’re still happy to see other LCD panels dropping unnecessary layers. Featured in a GPS mock-up, Toshiba’s 7-inch 1024 x 600 R&D display touts 10-point multi-touch over 38,400 sensors — that’s one touch sensor for every four pixels. It may not be the first LCD to abandon the standard touch layer for integrated capacitive support, but we wouldn’t shy away from a tablet or embedded screen featuring this 1mm wonder. We’ll have to wait though; Toshiba’s in-cell tech is still in R&D, with no word when or if we might see it in commercial devices. Check out the video after the break for a quick hands-on.
