  • Acer Launches First 4K Panel With NVIDIA G-Sync Technology On Board

    MojoKid writes: Save for a smattering of relatively small, 3K and 4K laptop displays, we haven't quite gotten to the same type of pixel density on the PC platform, that is available on today's high-end ultra-mobile devices. That said, the desktop display space has really heated up as of late and 4K panels have generated a large part of the buzz. Acer just launched the first 4K display with NVIDIA G-Sync technology on board. To put it simply, G-SYNC keeps a display and the output from an NVIDIA GPU in sync, regardless of frame rates or whether or not V-Sync is enabled. Instead of the monitor controlling the timing and refreshing at say 60Hz, the timing control is transferred to the GPU. The GPU scans a frame out to the monitor and the monitor doesn't update until a frame is done drawing, in lock-step with the GPU. This method completely eliminates tearing or frame stuttering associated with synchronization anomalies of standard panels. There are still some quirks with Windows and many applications that don't always scale properly on high-DPI displays, but the situation is getting better every day. If you're a gamer in the market for a 4K display, that's primed for gaming, the Acer XB280HK is a decent new option with this technology on board, though it does come at a bit of a premium at $799 versus standard 28-inch panels.

  • John Carmack's Oculus Connect Keynote Probably Had Samsung Cringing

    An anonymous reader writes John Carmack, famed keystone developer of 3D networked gaming, has now been working with virtual reality company Oculus for over a year. Much of that time has been spent collaborating with Samsung on the forthcoming Gear VR headset. At his keynote presentation during Oculus Connect, Carmack took to the stage with 90 unscripted minutes of no holds barred discussion of the last 12 months in VR. 'I believe pretty strongly in being very frank and open about flaws and limitations so this is kind of where I go off message a little bit from the standard PR plan and talk very frankly about things,' he said to applause from the audience.

  • Vrvana's Totem HMD Puts a Camera Over Each Eye

    The Verge reports that Montreal startup Vrvana has produced a prototype of its promised (and crowd-funded) VR Totem headset. One interesting aspect of the Totem is the inclusion of front-facing cameras, one over each eye, the output of which can be fed to the displays. Reviewer Mike Futter has worn a prototype, and seems to be generally impressed, writing at Game Informer: Vrvana’s device offers 1080p resolution and features 90-degree field of view (the same as the Project Morpheus, but less than the Oculus Rift's 100-degree FOV), an OLED display, and adjustable lenses that can compensate for lens prescription. The HMD is usable by glasses wearers, but the tuning provides an option for those that don't want to wear corrective lenses while in VR. The system connects via HDMI to any source, and can model 3D (side-by-side) from game consoles as virtual reality right now. The Totem is currently compatible with all Oculus developer kit 1 applications, and Vrvana is working on getting DK2 experiences working. The prototype I wore was a good proof of concept, but didn't yet feature the OLED screen. This led to increased persistence due to the LCD. The head tracking also wasn't perfect, requiring some software tuning to prevent drift (something easily surmountable down the road). The clarity was impressive, rivaling some of the best experiences I've had with a Rift or Morpheus.

  • New "Crescent Bay" VR Headset Revealed and Demo'd At Oculus Connect

    Oculus Rift revealed today its new 'Crescent Bay' prototype wearable display, at its inaugural Oculus Connect conference. (You can find more in the company's blog too.) From Gamasutra's coverage: The new headset has 360 degree tracking and integrated audio, as well as improved performance that allows better presence, says Iribe. It has higher resolution and a better refresh rate than even its recent DK2 headset. It's also much lighter than earlier prototypes. The company has also licensed technology from RealSpace 3-D for improved 3D audio on Oculus moving forward. Audio is becoming a priority for the company, [CEO Brendan] ]Iribe said. Road to VR has a gushing hands-on review: One of the stand-out demos put me in front of an alien on some sort of Moon-like world. The alien was looking at me and speaking in an unfamiliar tongue. When I moved my head, its gaze followed me. Its big and detailed eyes, combined with reaction to me as I moved, imbued it with a sense of living that was really cool. Spaceships flew over head and drew my gaze behind me, leading me to look at some incredibly detailed scenery.

  • Oculus Rift CEO Says Classrooms of the Future Will Be In VR Goggles

    jyosim writes "Oculus Rift isn't just for gaming. Brendan Iribe, CEO of the VR company, says the immersive tech will be "one of the most transformative platforms for education of all time." In an interview with Chronicle of Higher Education, he imagined laser-scanning every object in the Smithsonian for students to explore, and collaborating in shared virtual spaces rather than campuses. "The next step past that is when you have shared space, and not only do you believe that this object is right there in front of me, but I look around and I see other people just like we see each other now, and I really, truly believe that you’re right in front of me. We can look at each others’ eyes. If you look down at something, I can look down at the same time. And it’s every bit as good as this. And if we can make virtual reality every bit as good as real reality in terms of communications and the sense of shared presence with others, you can now educate people in virtual classrooms, you can now educate people with virtual objects, and we can all be in a classroom together [virtually], we can all be present, we can have relationships and communication that are just as good as the real classroom," he says.

  • Dell Demos 5K Display

    An anonymous reader writes: Even though 4k displays are just making their way into consumer affordability, manufacturers are already pushing beyond. Dell has previewed a computer monitor it calls a "5k" display. The resolution is 5120x2880, stuffing 14,745,600 pixels on a 27" screen. For comparison, that's more than seven times the amount of pixels in a 1920x1080 display. Pixel density is 218 PPI, roughly the same as a 15" Retina MacBook Pro. ExtremeTech suggests, "As far as we're aware, no one is actually making 5120×2880 panels, especially not at 27 inches diagonal – so what we're probably looking at is two 2560x2880 panels squished together as a 'tiled display.'" Unfortunately, it's pricy, expected to cost around $2,500. But hopefully it will help drive 4k display prices even further toward mainstream availability.

  • Samsung Launches Virtual Reality Headset For Galaxy Note 4

    An anonymous reader writes Samsung has launched a virtual reality headset called Samsung Gear VR Innovator Edition. It uses the new Galaxy Note 4 for a screen and technology from Oculus VR. The headset comes with four visual settings that simulate experiences such as sitting in a theater or being on stage. Despite partnering with Oculus, the Gear VR won't run Oculus apps, but Samsung says porting titles over shouldn't be too hard. From the article: "This is Oculus' first consumer product and, bizarrely, it's on a Samsung device. Oculus VR CTO John Carmack personally led the mobile software development team at Oculus, and the software interface is all built in collaboration with Samsung. It's basic: Point a reticle in the middle of the screen at what you want to select and tap the touchpad to select it. The options are sparse and base level, and the only content management that exists right now is a store of sorts. It looks like the Google Play store to an extent, except it's floating in space.

  • 60,000 Oculus Rift DK2 Orders, 20,000+ Units Shipped, New Orders Ship In October

    An anonymous reader writes The much lauded Oculus Rift DK2 is in high demand. Shipping began at the end of July and Oculus says they've already shipped more than 20,000 of their 60,000 orders. The company recently updated their order page to indicate that new units are expected to ship starting in October. The Oculus Rift DK2 is the company's second development kit which offers a number of major improvements over the original kit, called the DK1, which was the result of a successful Kickstarter back in August, 2012. Although the DK2 is intended for developers, the company openly offers the VR headset up for sale to anyone interested for $350. The Oculus Rift DK2s most notable enhancements are a higher resolution display and positional tracking capability as well as a number of other under-the-hood enhancements make the DK2 a huge improvement over its predecessor.

  • Android Motorcycle Helmet/HUD Gains Funding

    DeviceGuru (1136715) writes Skully Systems has achieved Indiegogo funding for a high-tech Android 4.4 based motorcycle helmet with a head-up display (HUD), GPS navigation, and a 180-degree rearview camera. The Skully AR-1 helmet launched on Indiegogo on Aug. 10 and quickly blasted past its $250,000 flexible funding goal and has already surpassed $900,000 in funding. The helmet runs a heavily modified version of Android 4.4, with both screen size and safety in mind, according to Skully's Tow. 'You should not think of it as being Android as seen in a phone; it doesn't run the same skin,' wrote Tow on the Skully forum page. 'You instead should think of it as a variant of Linux, not Android per se. What counts is the device drivers, graphics rendering for our turn by turn directions and vehicle telemetry, etc. More nerdy things like communication over the I2C bus to the image processing module.' Helmets are available starting at $1,399, with shipments due in May 2015.

  • New Display Technology Corrects For Vision Defects

    rtoz (2530056) writes Researchers at the MIT Media Lab have developed a new display technology that automatically corrects for vision defects without requiring glasses or contact lenses. This technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on, or electronic readers that eliminate the need for reading glasses. The display is a variation on a glasses-free 3-D technology: a 3-D display projects slightly different images to the viewer's left and right eyes. Similarly, this vision-correcting display projects slightly different images to different parts of the viewer's pupil.

  • iFixit Takes Apart the Oculus Rift DK2, Finds Galaxy Note 3 Display Inside

    An anonymous reader writes with a teardown from iFixit of the Oculus Rift Development Kit 2: "iFixit's teardown reveals lots of interesting hardware within, including 40 infrared LEDs, a well-organized motherboard, and a display panel lifted directly from a Samsung Galaxy Note 3. They also took apart the IR tracking camera for good measure." The review is the usual iFixit blend of funny, concise and technical; they include a nice shot showing those IR sources embedded in the plastic of the frame. Why the straight-from-a-phone display? "This seems to make economical sense, since Oculus is working to ship something like 45,000 DK2s—a goodly number for a mid-development prototype, but certainly not enough to warrant a fully custom display."

  • The Oculus Rift DK2: In-Depth Review (and Comparison To DK1)

    Benz145 (1869518) writes "The hotly anticipated Oculus Rift DK2 has begun arriving at doorsteps. The DK2s enhancements include optical positional tracking and a higher resolution panel, up from 1280×800 to 1920×1080 (1080p) and moved to a pentile-matrix OLED panel for display duties. This means higher levels of resolvable detail and a much reduced screen door effect. The panel features low persistence of vision, a technology pioneered by Valve that aims to cut motion artefacts by only displaying the latest, most correct display information relative to the user's movements – as users of the DK1 will attest, its LCD panel was heavily prone to smearing, things are now much improved with the DK2."

  • Day One With the Brand New Oculus Rift DK2: the Good, the Ugly and the Games

    muterobert (2927951) writes Paul James goes hands on with one of the first next-gen Oculus Rifts in the wild: "After much hacking (and some kind developer linkage) I stepped into a DK2 enabled version of Technolust and lost myself utterly! The stunning attention to detail, neon on black really lets the OLED panel shine here. In fact, this experience was the closest I think I've ever some to presence in virtual reality thus far. Leaning in to check the myriad retro objects, gawking at the lighting and just generally being blown away by the experience. This game was fabulous on the DK1, it's utterly compelling now."

  • "Magic Helmet" For F-35 Ready For Delivery

    Graculus writes with news that the so called "magic helmets" for the controversial F-35 are ready for action. This week, Lockheed Martin officially took delivery of a key part of the F-35 fighter's combat functionality—the pilot's helmet. The most expensive and complicated piece of headgear ever constructed, the F-35 Gen III Helmet Mounted Display System (HMDS) is one of the multipurpose fighter's most critical systems, and it's essential to delivering a fully combat-ready version of the fighter to the Marine Corps, the Navy, and the Air Force. But it almost didn't make the cut because of software problems and side effects akin to those affecting 3D virtual reality headsets.

    Built by Rockwell Collins ESA Vision Systems International (a joint venture between Rockwell Collins and the Israeli defense company Elbit Systems), the HMDS goes way beyond previous augmented reality displays embedded in pilots' helmets. In addition to providing the navigational and targeting information typically shown in a combat aircraft's heads-up display, the HMDS also includes aspects of virtual reality, allowing a pilot to look through the plane. Using a collection of six high-definition video and infrared cameras on the fighter's exterior called the Distributed Aperture System (DAS), the display extends vision a full 360 degrees around the aircraft from within the cockpit. The helmet is also equipped with night vision capabilities via an infrared sensor that projects imagery inside the facemask

  • Critroni Crypto Ransomware Seen Using Tor for Command and Control

    Trailrunner7 writes There's a new kid on the crypto ransomware block, known as Critroni, that's been sold in underground forums for the last month or so and is now being dropped by the Angler exploit kit. The ransomware includes a number of unusual features and researchers say it's the first crypto ransomware seen using the Tor network for command and control.

    The Critroni ransomware is selling for around $3,000 and researchers say it is now being used by a range of attackers, some of whom are using the Angler exploit kit to drop a spambot on victims' machines. The spambot then downloads a couple of other payloads, including Critroni. Once on a victim's PC, Critroni encrypts a variety of files, including photos and documents, and then displays a dialogue box that informs the user of the infection and demands a payment in Bitcoins in order to decrypt the files.

    "It uses C2 hidden in the Tor network. Previously we haven't seen cryptomalware having C2 in Tor. Only banking trojans," said Fedor Sinitsyn, senior malware analyst at Kaspersky Lab, who has been researching this threat. "Executable code for establishing Tor connection is embedded in the malware's body. Previously the malware of this type, this was usually accomplished with a Tor.exe file. Embedding Tor functions in the malware's body is a more difficult task from the programming point of view, but it has some profits, because it helps to avoid detection, and it is more efficient in general."

  • KDE Releases Plasma 5

    KDE Community (3396057) writes "KDE proudly announces the immediate availability of Plasma 5.0, providing a visually updated core desktop experience that is easy to use and familiar to the user. Plasma 5.0 introduces a new major version of KDE's workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered around an OpenGL(ES) scenegraph. Plasma is built using Qt 5 and Frameworks 5." sfcrazy reviewed the new desktop experience. It would appear the semantic desktop search features finally work even if you don't have an 8-core machine with an SSD.

  • Coming Soon(ish) From LG: Transparent, Rollup Display

    jfruh (300774) writes Korean electronics manufacturer LG has shown off experimental, see-through, roll-up displays, paper thin and flexible and capable of letting through about 30% of the light that strikes it. The company is eager to sell the concept and promises it'll be arriving soon, though they've shown of similar (though less capable) technology over the past few years and have yet to bring any products to market.

  • Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best

    Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame."

  • BlackBerry's Innovation: Square-Screened Smartphones

    EthanV2 sends word that BlackBerry, having finally caught up to a world dominated by smartphones, is now trying to push the envelope by developing a smartphone with a square screen. The BlackBerry Passport has a 4.5-inch screen with a resolution of 1440x1440. The phone has a physical keyboard as well. In a blog post about the new phone, they show a picture with it side-by-side with an iPhone and a Galaxy S5 — the Passport is slightly taller than the iPhone, and significantly wider, as you'd expect. The Passport is a play for BlackBerry's "traditional" work-oriented user base, where the earlier BlackBerry Z10 and Z30 were efforts to break into the post-iPhone consumer smartphone space. Though the Passport may well be preferable for spreadsheets and word processing, that square screen will be much less useful for widescreen movies, and its wide, blocky design will entirely prohibit one-handed use. The Passport is expected to appear later this year, and it will launch with BlackBerry 10.3 (at least, according to early hands-on previews).

  • All Web Developers Should Have Access to a Device Lab (Video)

    This interview with Googler Pete LePage took place at Google I/O 2014, where Pete and coworker Matt Gaunt set up a Device Lab with 46 different devices on their display wall. The point wasn't to show off Google's coolness as much as it was to let developers see how their websites displayed on as wide a range of mobile devices as possible. This is reminiscent of the last century's Any Browser campaign, which was set up to encourage developers to make sites that worked right in any browser instead of having a WWW full of sites "best viewed in Exploroscape" that displayed poorly in other browsers.

    Today, the trick is to make a site that is fully functional across a wide range of devices with different size screens that a user might decide to view in landscape mode one day and portrait mode the next. Google is happy to share their MiniMobileDeviceLab with you to help set up multi-unit displays. Pete also suggests checking out PageSpeed Insights and Web Fundamentals even if you're a skilled and experienced Web designer, because those two Google sites are chock full of information on how to make sure your site works right on most devices and in most popular browsers.
