About that iPhone touchscreen accuracy test
Recently, you may have seen a report from the automated testing company OptoFidelity regarding the accuracy of the touch panel on the iPhone 5c, 5s and the Samsung Galaxy S 3. The test was performed by having an artificial robot finger make hundreds of taps across each phone's display. The tap location was then compared against where the touch panel registered the tap. If the tap was registered within 1mm of where the robot finger actually hit, the tap was shown on OptoFidelity's display as a green dot. You can see the results in the image above. But that may not be the end of the story. Nick Arnott over at Neglected Potential has written a blog post questioning the roughly 75 percent inaccuracy rate OptopFidelity's testing showed for the iPhones. Someone reading their study would get the impression that the iPhone 5c and 5s have incredibly inaccurate screens, but something about the results didn't sit well with Arnott. So he took a finer look. He noticed that the main areas where the iPhone was getting the lowest scores were the left and right edges of the keyboard. OptoFidelity itself actually specifically mentions these areas in its study. Taking a finer look at where exactly the issues arose, Arnott noticed something that could easily explain the robot finger's odd tapping issues. Looking at the displacement of taps as you move away from the green area, there's a definite pattern. The more you move away from the easily-tappable area, the greater the "inaccuracy" of the tap. But the inaccuracy skews in a way that would make the target slightly closer to starting position of your thumb (which is likely the most frequently used digit for tapping). As your thumb stretches out from your hand, likely positioned near the bottom of the phone, the portion of your thumb that actually comes into contact with the screen when you tap changes. Your perception of the screen also changes slightly, as when you move higher on the screen, it's less likely that you're viewing the screen at exactly a 90 degree angle. These are factors that this automated test does not account for. The robot doing the test is viewing its tap target at a perpendicular angle to the screen. It is also tapping at a perpendicular angle every time. This isn't generally how people interact with their phones. While OptoFidelity's test indeed raises some questions about the iPhone's touch panel, Arnott raises an interesting point. Testers should always be asking questions. When OptoFidelity researchers received the test results, did they look at the methodology and how it affected the touch recognition on the panel? Did the OptoFideltiy test take into account the different sizes of the iOS devices and the Galaxy S3 and how they fit differently in users' hands? Arnott is not saying that OptoFidelity's tests are necessarily wrong, though he has issues with the results. He is merely reminding all of us that when we are testing a product or even just reading a report, we should be questioning the findings. That's how products get better, and how reports that raise questions can help answer them.
Vizio preps for Windows 8: all-in-one PCs get touchscreens, notebooks get 'enhanced' touchpads
As is all the rage right now, Vizio is upgrading its lineup to support Windows 8's more touch-centric UI. The company's 24-inch and 27-inch all-in-one PCs will receive touch panels, resulting in a price bump to $998 for the base 24-incher with Ivy Bridge and Kepler internals, 1920 x 1080 display and 500GB hard drive. Meanwhile, Vizio's Ultrabooks -- both the 14-inch and 15.6-inch models -- and its heftier 15.6-inch Full HD notebook will all get "enhanced multi-gesture touchpads" that will allow exactly the same swipes, taps and pinches as a touchscreen. These laptops will start at $849 for the smaller Ultrabook and $1,129 for the notebook. Expect the whole lot to arrive as part of the late October crush.
Double-sided transparent touchscreen shown off on NTT DoCoMo prototype (video)
See-through displays may or may not be making a comeback, but NTT DoCoMo is at least trying to give them a different spin. Working with Fujitsu, it's added a Vita-style extra touch panel to the rear of the screen, which works with the transparency to let the user navigate Android without ever obscuring the UI with their fingers. It also allows new types of interaction based on "gripping" objects -- holding down a finger at the back to modify the effect of a swipe on the front. The prototype was actually announced a little while back, but DigInfo has a video (embedded after the break) that shows how it works in practice -- just don't expect to be enjoying Netflix on that washed-out QVGA display anytime soon.
Super High Aperture: it's why the new iPad's Retina display is so dense
Super High Aperture. Heard of it? Probably not, but thanks to Apple, you'll probably long for days when you didn't in just a few months. According to an in-depth look from the folks at DisplaySearch, the aforesaid technique is the primary reason that Apple was able to shove 2,048 x 1,536 pixels into the 9.7-inch panel on the new iPad. Not surprisingly, it wasn't Apple that conjured up the magic; instead, it was crafted by engineers at Sharp and JSR (a display materials maker from Japan), but it'll be the iPad that makes an otherwise geeky achievement something that the mainstream covets. According to the science behind it, SHA is "a method of increasing aperture ratio by applying approximately a 3 [micrometer] thick photo-definable acrylic resin layer to planarize the device and increase the vertical gap between the [indium tin oxide] pixel electrodes and signal lines." Reportedly, there are also "at least twice as many" LEDs in the panel compared to that on the iPad 2, further suggesting that there's way more battery within the new guy than the last. Technophiles need only dig into the links below to find plenty more where this came from.
SMK's touchscreen registers your gloved swipes, won't acknowledge the bad touch
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.
Perceptive Pixel shows world's largest projected capacitive display at SIGGRAPH, we go hands-on (video)
Perceptive Pixel wasn't kidding around when it launched the planet's biggest projected capacitive display here at SIGGRAPH -- all 82 inches of it were here on display, and naturally, we stopped by to give it a look. While 82-inch panels aren't anything new, this one's particularly special. You see, the company actually procures the panels from Samsung, and then it rips the guts out while bonding its own network of sensors directly to it; most large-screen touch devices simply pop a touch layer on top of whatever TV shows up in the labs, but this integrated approach takes sensitivity to a whole 'nother level. For those unfamiliar with the term 'projected capacitive,' we're surmising that it's actually far less foreign than you think -- it's a technology used in a handful of smartphones, from Samsung's Moment to Apple's iPhone. 3M was also showing off a PC tech preview back at CES, and after using it here on the show floor, there's no question that it's the future for larger-screen devices. To quote CEO Jeff Han: "once consumers get a taste of this on the mobile front, they start demanding it elsewhere." %Gallery-130284%
Habey USA's 12-inch panel PC brings that rugged look to your home
It's a shame this steel-encased touchscreen PC from Habey USA arrived too late for our violent outburst on the Engadget Show, but at least it has some broadly agreeable specs. The PPC-6512 can reel off 1080p vids on its 12-inch screen while consuming just 30W thanks to its 1.8GHz Atom D525 and NVIDIA Ion GT218 combo. An empty 2.5-inch removable HDD tray and eSATA port give it potential as a networked storage hub, and an old-school serial port lets it handle home automation controls too. It could also be used as a comms or security terminal, as there's a 1.3MP webcam on board, vesa mounting holes and four USB 2.0 ports. Heck, we'd buy three and rig our whole house up -- were it not for the $800 price tag, the apparently limited availability on Habey USA's underloved Amazon page, and the fact that we like our terminals to show a bit of emotion. Full specs in the PR after the break.
Apple adds third supplier of iPad 2 touchscreen components
Chimei Innolux Corp. is joining TPK Holding Corp. and Wintek Corp. as the third provider of touch panel sensors for the Apple iPad 2. Chimei will begin supplying the panels next month, Bloomberg said. TPK and Wintek will still be the primary suppliers of the touch panels, but Chimei's contribution will help Apple meet the growing demand for its popular tablet device. Demand for the iPad 2 is "amazing," Apple's spokesperson Trudy Miller said. The tablet device flew off retail store shelves when it launched earlier this year, and demand has been high ever since. Despite being available in several retail channels including Toys R Us, Wal-Mart and Best Buy, the iPad 2 is still difficult to find in stores, and the wait time for online orders is still 2-3 weeks. Incidentally, this deal with Chimei will help solidify Apple's position with Foxconn, the primary assembler of the iPhone and iPad. Chimei was formed last year when Foxconn-owned Innolux Display merged with Chi Mei Optoelectronics Corp. and TPO Displays Corp.
New silver-packing transparent conductive film could mean more durable touchscreens
We first heard of the wonders of silver ink back in 2009, but it wasn't until earlier this year, with talk of 3M's new capacitive touchscreens, that we experienced its real-world potential for display technology. Well, it looks like 3M's not the only name in the Ag game, in fact Tokyo-based Toray Industries recently announced the development of a transparent conductive film that ditches the traditional ITO (indium tin oxide) for silver wire. In order to produce this new material, a layer of Ag wires, measuring several hundred nanometers, is applied to a polyester (PET) film by way of a wet method. The result, the company said, is a more flexible, durable, and transparent film that is well suited to touchscreens of just about any size. There's no word yet on when the film will appear on real-deal devices, but we'll definitely keep an eye out for the silver screens. Full PR after the break.
Apple's touch panel demand helped delay RIMs PlayBook
RIM announced its PlayBook tablet last year, and eager BlackBerry fans have been waiting months for this QNX-based tablet to debut. According to a rumor from Digitimes, this wait was made even longer thanks to Apple and its stranglehold on the touch panel market. Asian supply chain sources suggest Apple used its treasure chest of cash to secure touch panels for its iOS devices, leaving other manufacturers out in the cold. RIM reportedly delayed the PlayBook while it secured touch panels and put the finishing touches on its tablet OS. Digitimes is notoriously hit or miss with its insider information, but in this case, its report may be accurate. Apple is known for its ability to secure critical device components from Asian suppliers before its competition. A few years ago Apple cornered the market on NAND Flash for its iPhone and iPods while other manufacturers were left scrambling for the scraps.
Apple could agree to component price hike to secure touchscreens
Contending with seemingly insatiable demand for its new iPad 2, Apple is pondering paying higher prices for touch panel components, according to a report from DigiTimes on Wednesday. Manufacturers in Taiwan claim Apple is more open to certain price hikes during negotiations as the California company tries to secure a sufficient supply of components for its popular touchscreen products. Higher component prices, in the short term, will shrink Apple's gross margins on three of its hottest selling products: the iPad, iPhone and iPod touch. But securing adequate availability of touch panels should help the company relieve some of the constraints in its global supply chain. Such a deal would also put pressure on other consumer electronics companies to pay more for the components they need to build competing tablet computers and smartphones. Apple currently faces incredible pressure from consumers and shareholders to address bottlenecks in the supply chain for its successful families of touch panel devices. Lead times for the new iPad 2 ballooned to 4–5 weeks in its first few days on the US market, and the tablet goes on sale to a broader, global market this Friday. Apple reportedly expects to ship 40 million iPads in 2011. The company is also expected to launch its next generation iPhone later this year. The earthquake and tsunami that struck Japan earlier this month further fueled concerns over possible touch panel supply shortages. According to AppleInsider, a recent report suggested Foxconn, Apple's manufacturing partner, has only two or three weeks' worth of touch panels stockpiled. If the situation in Japan doesn't improve, Foxconn could deplete its stock of touch panel components. Despite these concerns, DigiTimes believes Apple is well positioned to weather a shortage of touch panels. Apple has already booked an estimated 60 percent of the world's touch panel output capacity. As the global market leader in touchscreen devices, Apple will continue to control the lion's share of the world's touch panel supply and enjoy lower component pricing than its competition. "Supply for touch panel[s]...will be more smooth for Apple," concluded DigiTimes. [via AppleInsider]
Forget the white iPhone 4, white iPhone 5 rumors begin!
It's the perfect rumor: the officially delayed and frequently tattled white iPhone 4 has reemerged as the white iPhone 5 riding a horned stallion through virgin rumor fields. According to the Economic Daily News, the previously unheard of white iPhone 5 will feature a touch panel supplied exclusively by Wintek. If true, then the white iPhone 4, officially scheduled for a spring 2011 launch, should be available just prior to the launch of the next generation white iPhone 5, anticipated for a summer launch in keeping with Apple's typical launch cycle. Not exactly ideal, but hey, it's only the first of many related rumors to come. P.S. Here's a link to an Apple-free Engadget in anticipation of your needs.
Apple creating touch panel shortages for tablet competition?
Things tend to get messy for the competition when Apple decides to direct its vast cash reserves on "very strategic" components. Especially when Cupertino starts waving around stacks of dough in the range of $3.9 billion to $7.8 billion. For reference, just look at what Apple did to NAND supplies as the flash-based iPod rose to dominance. Today DigiTimes is reporting that Apple is occupying close to 60 percent of the global touch panel production capacity from the likes of Wintek and TPK resulting in "tight supply" for the competition. The impact on consumers, according DigiTimes' sources at upstream component makers, is that tablet PC makers are unable to ship enough product to match orders due to component shortages. The issue is especially troublesome for second-tier tablet hopefuls who must compete with the likes of HP, RIM, Motorola, HTC, Samsung, LG, Dell (everyone but Sony) for the scraps. As a result, Apple should be able to more easily meet iPad demand in 2011, according to DigiTimes, while its competitors struggle to keep up.
IDT transmit touch information over DisplayPort's auxiliary channel
Still wondering if the future of display linkage really lies in DisplayPort? Hard to say for sure, but IDT's definitely making a good case for it with its latest demonstration. Integrated Device Technology has seemingly figured out how to shuffle touch information through DisplayPort's existing auxiliary channel, which simplifies and lowers the cost of integrating touch technology into tablets, laptops, AIO PCs, monitors, etc. It's being hailed as the world's first usage of the DisplayPort AUX channel to carry touch screen data, and if the prototype proves solid, it'll allow laptop manufacturers to eliminate USB interface communication from host to panel and reduce the number of wires that must pass through the display's hinge. And you know what that means -- slimmer, more flexible designs. IDT's not barking about a release date for its latest trick, but we're guessing it'll have display makers begging for access in no time flat.
Centrafuse leads to iPhone control via touchscreen, carputer dreams come to life (video)
We've seen countless individuals integrate their phone, PMP or tablet into their whip, but for years, we've all been thinking the same thing: "There has to be an easier way." Turns out, there is. One Mr. Romin has seemingly unearthed the solution, which involves a Lilliput FA1042 touchpanel, a Belkin AV dock adapter cable and a critical piece of software by the name of Centrafuse. Working in conjunction, he has enabled his monitor to actually control the iPhone, and when firing up a YouTube video, the content plays back on the big screen while the controls remain visible on the handset. It's a nifty setup, for sure, and we're downright excited to see this rig get installed in a vehicle far too small for American roads in a fortnight or so. For now, catch it working in action just past the break.
18-screen digital paint wall supports touch, iPad doodling (video)
Look, we all love finger painting. It's an American tradition, after all. But just like nap time, it somehow vanishes into oblivion once adulthood creeps into play. But a sect of kids at the University of Illinois at Chicago aren't about to enter the so-called "real world" without a few more flicks. Researchers at the institution have crafted a digital paint wall out of 18 HD screens. Total resolution? 8160 x 2304 pixels. Better still, the wall is touch-enabled, and if you can't get close enough to doodle, there's an iPad app that lets an extra artist add their touch via WiFi. Currently, it can handle 32 touches at once, and those in charge are hoping to make it play nice with multiple tablets in due time. Hit that play button below for a look at what you're missing, Mr. Grown-Up. [Thanks, Jason]
Displax Overlay Multitouch turns your LCD or plasma into a touchscreen, demands a pretty penny
Remember when Displax teased us earlier in the year with a polymer film that could take any conventional LCD, plasma or RPTV and turn it into a touchscreen? Yeah, well now that very technology is shipping to Average Joes and Janes like yourself your good pal Jim. Starting nowish, the outfit's customizable Overlay Multitouch will be heading out to screens ranging from 32- to 103-inches in size in order to add multitouch capabilities to a screen that previously hated even the thought of being groped. Of course, with a starting tag of €1,300 ($1,805), we get the impression that most of the orders (at least initially) will be coming from corporations looking to jazz up their boardrooms. In related news, the company is also debuting a 42-inch Windows 7-based multitouch table that can detect up to four independent touches at once. The Oqtopus uses a specific kind of optical technology that allows bare fingers, styluses and even gloved hands to operate it, but with a starting price of €4,500 ($6,250), we're guessing your own personal Santa is already signaling "no." %Gallery-104429%
SanDisk Sansa Fuze+ review
SanDisk's original Sansa Fuze may have had a solid run -- it's been a particular favorite among those looking for a good, inexpensive player that doesn't skimp on features or audio quality -- but there's no question that it was long overdue for an update, and SanDisk recently came through on that front with the completely revised Sansa Fuze+. Boasting a considerably sleeker design, the Fuze+ replaces the Fuze's venerable tactile click wheel with a capacitive touch panel (but not a touchscreen), and it hangs onto many of the features that made the original Fuze stand out, including a microSD card slot, FM radio, and support for a wide range of formats (including FLAC and AAC). Are all the changes for the better? Read on for our full review. %Gallery-103839%
Renshui rethinks the bathroom faucet
True revolutions in faucet designs may be few and far between, but China's Renshui is certainly doing its part to shake things up, and has now introduced yet another faucet sure to amaze and confuse visitors to your humble abode. In addition to breaking with the usual faucet design, this model packs a touch panel that will let you switch between hot and cold water, or dial in the exact temperature you want -- which is, of course, displayed on the faucet itself (it'll even warn you if the water is getting too hot). No word on availability over here, but it did recently win a red dot design award, so the chances of a release may have gotten a bit better.
LinnStrument multitouch music maker gets demoed on video, grasps for investors
Roger Linn. Ever heard of him? He's only the man behind the modern day drum machine and the original MPC-60, and he's also the man behind the concept you're inevitably peering at above. For now, Roger's calling this beaut the LinnStrument, and there's quite a back story to go along with it. The design began way back in 2006, with the goal being to create a full-on multitouch instrument with the ability to let one's finger dictate volume, timbre, pitch and pressure. No doubt, many have tried to concoct something similar, but Roger's discovery of TouchCo enabled him to create one sans the limitations of imitators. Unfortunately, Amazon quietly scooped up the startup in January of this year (to have this sort of technology available for the Kindle product line), and in turn, shut down TouchCo's involvement with the outside world. Now, Roger's being forced to reveal his unfinished work in hopes of attracting investors or unearthing another company that could mimic this sort of awesomeness en masse. Jump on past the break and mash play to get a better idea of what the world's missing out on, and be sure to tell Jeff Bezos "thanks" the next time you bump into him. [Thanks, Peter]
