'Free form' lens over mobile display could improve audio and haptics, says Motorola patent filing
It's hard to tell exactly what Motorola is thinking of here, but it probably isn't a billowing sheet of fabric stretched loosely over the face of a smartphone -- even if that's what it looks like. Instead, this appears to be a patent application for a "free floating display lens" that helps the panel of a mobile device to be used as a Beo-style acoustic speaker. The idea is that you can get louder and less resonant sound without having to dedicate more precious real estate to a larger traditional speaker unit. The application also talks about generating haptic feedback on the lens, using the same underlying piezoelectric structures that would power the audio. Creating vibrations this way could require "eight times" less voltage than current methods while also delivering a higher-amplitude sensation. Merge that with KDDI's weird vibrational speaker technology and the results could be deafening.
Patent application highlights Apple's continued flirtation with haptic feedback
We could all use a little feedback, right? Even Apple. The company has been toying around with the concept of haptic feedback for a while now, at least so far as patent applications are concerned. Another application filed in November or 2010 has surfaced. Of course, what we told you back in 2009 about the tenuous connection between an application and an actual product is as relevant as ever. Still, Apple's concept for a "tiered haptic system" which "may use one or more arrays of shape change elements to provide a wide range of tactile feedback" demonstrates that, at least as of late 2010, Cupertino was still working to rethink the way it sees touchscreens.
Researchers suggest haptics and audio for discreet password input
You can use as complex as a password as you like, but that won't do you much good if someone's able to watch or record you entering it. Researchers Andrea Bianchi, Ian Oakley and Dong-Soo Kwon have some ideas for overcoming that little problem though, and recently put together a video demonstrating a few of the possibilities they've come up with. All of those rely on haptic input systems -- either on their own or in conjunction with some audio output (through headphones for privacy). That includes things like a dedicated haptic keypad or haptic wheel, and different methods that could take advantage of a haptic display on a smartphone. As you can see in the video after the break, some of those options could be a bit more time consuming than an easy-to-remember password, but there's certainly plenty of potential applications where security would trump convenience.[Thanks, An]
AT&T Labs, Carnegie Mellon research haptic-feedback steering wheel for turn-by-turn directions
A force-feedback steering wheel. It's quite literally the stuff of racing games, and AT&T labs, along with Carnegie Mellon, is researching the possibly of throwing similar tech into your real-world whip. MIT's Technology Review recently highlighted the project, which uses 20 vibrating actuators shoved inside of a steering wheel to create a variety of patterns -- a counter-clockwise sequence could indicate a left turn, for example. As you might have guessed, one of the goals is to keep drivers less distracted by the likes of visual turn-by-turn GPS navigators and more focused on the road. While it's currently being tested with driving simulators, the results are positive so far, if a bit modest. When supplemented with typical audio / visual navigation, folks near the age of 25 kept their eyes planted on the asphalt for 3.1 percent more time than without it. Notably, the improvement wasn't found with those over 65 in the aforementioned instance, however, supplemented with just the audio, the vibrating wheel had them focusing on the road by an increase of four percent.According to Technology Review, this isn't the first time haptic feedback has been tested as a driving aid, although past tests have, notably, resulted in "fewer turn errors" by those behind the wheel. Best of all, the tech is capable of sending more than just navigation cues -- it could certainly be useful in a Telsa. So when can you expect to find a force-feedback steering wheel in your ride? Technology Review cites Kevin Li, an AT&T Labs researcher on the project, who says the main hurdle is making something that people will just "get," and that it's still "years" away from becoming a possibility. While there's no photos of the setup just yet, a full report on the research will get released in June. Hey, there's always Forza and Gran Turismo, at least for now -- right?
Nokia applies for skin-friendly haptic material patent, hints at notification system
If US patent application 20120062371 is to be correctly understood, Nokia has at least thought about a topical haptic notification system. The first claim covers "An apparatus comprising: a material attachable to skin, the material capable of detecting a magnetic field and transferring a perceivable stimulus to the skin, wherein the perceivable stimulus relates to the magnetic field." It then goes on to clarify its relation to telecommunications messages and communications indications. Based on ferromagnetic powder, the material would respond to magnetic fields and vibrate in response. Our guess is that this could be used as a notifier that could be "painted" onto the skin, and although there is mention of the word tattoo, we're hoping that's just part of the required legalese. But alas, until it's granted, it's just a subject of our curious imaginations. Those curious, can read more at the source.[Thanks to everyone who sent this in]
Something to touch: Haptic feedback rumor gains traction for iPad "magic" feature
It's always something at the last minute. Yesterday, the UK's Guardian newspaper stoked the iPad rumor fires with a nuclear blowtorch by pairing the verbiage of Apple's event invitation -- "We have something you really have to see. And touch." -- with the work of a Finnish technology company called Senseg. A similar speculation hit over at The Next Web, and a MacRumors forum member outlined the argument last week. Senseg's patented screen technology creates a layer of "tixels," texture pixels that allow developers to control the feel of the screen; smooth to rough, slippery to sticky. The company's tech leads did a demo for the Guardian in January, where the reporter was able to identify on-screen textures (sandpaper, cloth, ridged surface) with eyes closed. Senseg's been fairly close-mouthed about any relationship with Apple when asked about it over the past few months, but that hasn't always been the case. Back in June of 2011 VP Ville Mäkinen let slip that Senseg was "currently working with a certain tablet maker based in Cupertino." Oh really. GigaOM pointed out this Cnet video demo of the Senseg technology (from November 2011), which of course appears just as if Rafe Needleman is using an ordinary tablet. The real innovation of Senseg's system is that unlike other haptics approaches, the screen uses electrostatic attraction to modulate the friction between finger and surface. No moving parts and "just works" simplicity -- sounds pretty Apple-esque. While Senseg executives have wisely delivered no comment on the upcoming Apple event, the notion of a sensable screen for the iPad aligns awfully neatly with Apple's collection of patents covering haptic interface elements like keyboards. Unlike some other Apple innovations that don't necessarily align immediately with users' needs, there's no question about this one: giving tactile feedback to iPad typists would provide a real-world benefit right away. And don't even get us started on what haptics would mean for game developers. Be sure to join us for our metaliveblog coverage of Apple's announcements, coming up in just a couple of hours.
Experimental controller has 'thumbstick within thumbstick' for blistering sensations (video)
Just when you thought slingshots were the future, here comes a whole new way to enjoy baddie deletion in Uncharted 7. Each thumbstick on the prototype controller above has a secondary force feedback-enabled nub at its center, which moves independently and creates different sensations by stretching the skin on the pad of your opposable digit. In the video after the break, the designers at the University of Utah show how they've created effects for crawling, collisions, explosions and even fishing. They're apparently hoping to push their technology into next-gen games consoles, but they'll have to join the queue.
Hands-on with Immersion HD Integrator hi-fi haptics
It was just over a year ago when we met with the folks from Immersion, and they showed us a prototype handset packing its HD haptics technology. Since that time, the piezoelectric actuator that makes the tactile magic possible has gone into mass production, and the first commercial device packing such hi-fi haptics, the Pantech Element, hit store shelves. Immersion's got greater aspirations for its tactile tech, however, and its new HD Integrator platform aims to put high fidelity haptics in every handset. We got to sample the HD haptics goods once again and chat with Immersion about the new platform and its technology, so head on past the break to see what the company has in store.
Cryoscope gadget simulates tomorrow's weather today (video)
This multi-layered device can't shower you with hail or tan your outdoor-deprived complexion, regrettably. What it can do though, is deliver a direct haptic sensation of how warm or cold it'll be tomorrow, just in case you decide to venture out of your bedroom. An Arduino controller pulls in forecast data from the web and uses it to adjust a Peltier element and a cooling fan, which are housed along with a heat sink inside a neat and tactile aluminum box. The Cryoscope is the handiwork of industrial design student Robb Godshaw, and it's the reason he already knew he'd be wearing a skinny t-shirt and stripey socks in the video after the break.
GTA III for Android hits 1.3, brings Liberty City to the Transformer Prime
Select iOS and Android devices have had the ability to terrorize Liberty City while on-the-go since December, but sadly those with Transformer Primes thus far have been left out of all that fun. Luckily, an update to the game ends that double standard, enabling Rockstar's classic to run on ASUS' tablet and Medion Lifetabs everywhere. It doesn't just bring expanded hardware support to the table though, as amongst other "technical fixes," the release also heralds new video display settings, Immersion haptics support and the capability of installing the game on a SD card. And fans of tactility, know that controls on the Xperia Play have been reworked, and it now boasts full support for GameStop's wireless controller. Still here? You shouldn't be -- grab the update in the source link below.
German researchers create smudge repellent coating from candle soot
While they're working on the lack of feedback, and need for exposed skin problems for touch screens, that other gripe -- dirty smudges -- could soon be wiped-out permanently. Researchers from the Max Planck Institute for Polymer Research in Mainz obviously had enough of sleeve-cleaning their devices and created a coating that could usher in a smudge-free world. The discovery comes after the team applied candle soot to glass and then coated it in silica to keep it in place. The glass is then heated to a bratwurst-baking 600 ºC for calcination, which makes the soot transparent -- somewhat handy for screens. To test, different oils and solvents were applied, but the glass' superamphiphobic properties soon fended them off. A resilient coating sounds a little more straight-forward than what Apple recently applied to patent, but until either of these see the light of day, you'd better keep that Brasso close by.
FingerFlux system uses magnets to add tactile feedback to touchscreens
We've seen a number of efforts that promise to make touchscreens more tactile, but none quite like this so-called FingerFlux system developed by a team of researchers from Germany's Aachen University. Its hook is a layer of magnets that lie beneath the touchscreen and react to a simple thimble that the user must wear. While that particular accoutrement could be considered a slight drawback, it does open up a number of interesting possibilities -- including the ability to draw your finger towards an item on the screen, and "lock" it in a certain area. What's particularly key, however, is that you're also able to feel a bit of feedback before you even touch the screen -- as opposed to other entirely screen-based options -- which could could let you operate something like media player controls without actually looking at your phone. Of course, it's all still a long ways from being shrunk down to phone-size, but the researchers do have a working prototype in a table-top device. Check it out in the video after the break.
ViviTouch haptic technology hands-on: electroactive polymer giving a 'high definition feel'
Haptic feedback isn't exactly something that'd blow people's mind these days, with most mobile devices and gaming controllers already packing a little vibrator to spice up one's gaming experience. While these motors do the job just fine for delivering the sensation of large engines and explosions, their monotonic performance and relatively high minimum output threshold means they can't reproduce finer vibration. For instance, you wouldn't be able to feel a guitar string fade away after a strum, nor would you feel the finer end of a spring recoil. This is where Bayer MaterialScience's ViviTouch -- previously dubbed Reflex -- tries to fill the void. For those who aren't familiar, the magic behind ViviTouch is its electroactive polymer (or EAP in short) -- imagine a thin sheet that consists of two electrode layers sandwiching a dielectric elastomer film, and when a voltage is applied, the two attracting electrodes compress the entire sheet. This slim, low-powered ViviTouch actuator module can be placed underneath an inertial mass (usually a battery) on a tray, thus amplifying the haptic feedback produced by the host device's audio signal between 50Hz and 300Hz (with a 5ms response time). %Gallery-134043%
'Phantom sensation' haptic tech recreates the feeling of getting virtually stabbed
When it comes to gaming, the more realistic the better, right? Sure, it's all fun until we start talking about being virtually sliced with a battle axe or pelted with a rocket launcher -- exactly the idea behind a new technology dubbed "phantom sensation." Researchers at the University of Electro-Communications know that to virtually recreate the feeling of touch, they need to apply vibrations to two points of skin. Taking the idea one step further, they applied the stimuli to either side of the body to mimic what it might feel like if the object actually passed through. Using a tweaked Wii, as an item in the game travels through the player's hand, the top sensor vibrates intensely at first, then subsides to zero. At this point, the bottom probe kicks in, going from zero to strong until the object is cleared -- leaving the player feeling slightly violated and virtually gored. Check out the (relatively) painless demonstration video after the break.
Audio-Haptic Navigation Environment makes music the hands-free way (video)
You've heard of pianists, flutists and organists, but have you heard of Thereminists? The title, originally applied to players of another hands-free instrument from the 1920s, has been repurposed for those who can manipulate invisible sounds in a 3D space called an Audio-Haptic Navigation Environment (AHNE). By tweaking a Kinect sensor and using the OpenNI framework and OSCeleton, researchers at the SOPI Research Group at Media Lab Helsinki were able to create an AHNE "proof concept" called "Tension." Outfitting a volunteer with sensor-laden gloves with a small vibration motor for haptic feedback, they were able to create "music" -- add a pinch of Pitbull, and you're looking at the world's next great mellow anthem. Check out the full music video after the break.
HAPMAP navigational system keeps your eyes on the prize, your hands on the route (video)
Alternative navigational systems aren't exactly new, but the concept shown here just might have wings. HAPMAP was one of a handful of projects selected for demonstration at SIGGRAPH's E-tech event, aiming to keep a human's eye away from the map (and in turn, on whatever's in front of them) by developing a system that guides via haptics. With a handheld device capable of both navigating and vibrating, the interface indicates complex navigation cues that follow the curvature of a road or path -- it's far more detailed than the typical "go straight," and there's also opportunity here to provide handicapped individuals with a method for getting to previously inaccessible locales. By mimicking the operation and interface of sliding handrails (as well as using motion capture cameras), it's particularly useful for the visually impaired, who need these subtle cues to successfully navigate a winding path. Hop on past the break for a couple of demonstration vids. %Gallery-130395%
Wrist sensor turns the back of your hand into a meaty haptic interface (video)
We're all intimately familiar with the backs of our hands, so why not use them as a haptic interface to control our gadgets? That's the idea behind the device pictured above -- a nifty little wrist sensor that turns your paw into a flesh-toned trackpad. Designed by Kei Nakatsuma, a PhD student at the University of Tokyo, this contraption employs infrared sensors to track a user's finger as it moves across the back of a hand. These movements are mirrored on a wristwatch-like display, thanks to seven IR detectors and a set of piezoelectric sensors, effectively turning any digit into an organic stylus or mouse. Nakatsuma, who unveiled his work at this week's SIGGRAPH, says his creation can't handle the more complicated, pinching or rotating gestures you could manipulate on most smartphone touchscreens and acknowledges that the screen can be difficult to read in direct sunlight. But the underlying technology could pave the way for similarly handy designs, while allowing users to interact with their gadgets without having to constantly glance at their screens, or go fishing in their pockets. Feel your way past the break to see a video of the device in action.
Surround Haptics could bring force feedback to vests, coasters and gaming (video)
Haptics and gaming have gone hand in hand for centuries it seems -- well before the Rumble Pak made itself an N64 staple, we vividly recall snapping up a vibration jumpsuit for our Sega Genesis. 'Course, it was on clearance for a reason. Ali Israr et al. were on hand here at SIGGRAPH's E-tech conference to demonstrate the next big leap in haptics, joining hands with Disney Research in order to showcase a buzzing game chair for use with Split/Second. The seat shown in the gallery (and video) below cost around $5,000 to concoct, with well over a dozen high-end coils tucked neatly into what looked to be a snazzy padding set for an otherwise uneventful seating apparatus. We sat down with members of the research team here in Vancouver, and while the gaming demo was certainly interesting, it's really just the tip of the proverbial iceberg. The outgoing engineers from Black Rock Studios helped the team wire stereoscopic audio triggers to the sensors, with a left crash, right scrape and a head-on collision causing the internal coils to react accordingly. Admittedly, the demo worked well, but it didn't exactly feel comfortable. In other words -- we can't exactly say we'd be first in line to pick one of these up for our living room. %Gallery-130406%
Kinect-driven tactile bodysuit makes you tingle in eight different places
We know the US Army has already experimented with vibrating clothing, and soon it could be our turn. The trendy figure-hugger above is rigged with haptic actuators across the arms and torso, which respond when the wearer's body 'touches' virtual objects created via Microsoft's Kinect platform. The outfit's designers at the University of Aachen spent just a few hundred dollars on components, aside from the cost of the Kinect, so this might well have commercial potential. Click the source link if you're really keen to see a concept video -- although it doesn't consist of much beyond a German dude doing the Hey Macarena in his socks. [Thanks, Jarod]
ViviTouch haptic tech offers range of feedback, aims to reinvent the mobile gaming wheel
When a company touts a product as being as revolutionary as the leap from black & white TV to color, it's either incredibly delusional or it has a damn good product on its hands. And judging by the buzz surrounding Artificial Muscle's ViviTouch tactile feedback technology and our own hands-on at CES, we're inclined to believe its braggart rights. Taking the "one-buzz-fits-all" approach and chucking it in the bin of 'ye olde tech of yesteryear,' the electroactive polymer tech creates a "spectrum of feeling" in the 50 - 300Hz range that registers with a user's hand in five milliseconds. We know what you're thinking -- haptic minutiae is fine and all, but what about my battery life? Well, if the company's CEO is to be believed, the vibrating touch interface drains 70 percent less juice than rival implementations -- so it's still hoggy, but not quite as hungry. If you're looking to get a feel of your own for these sensational claims, you'll have to wait for the Mophie Pulse to make its way to fourth generation iPod touch's later this year. Buzzwordy presser after the break.
