I can finally do cartwheels in VR with HTC’s Vive Focus

After fully unveiling the Vive Focus, HTC finally allowed lucky folks like myself to properly test out the six-degrees-of-freedom (6DoF) standalone VR headset. For the first time, I can actually walk around in VR without being tethered to a PC nor confined to a fixed space. It’s a truly mobile VR solution — more so than smartphone-based VR headsets, which only let you look around on the spot (3DoF). Naturally, I used this opportunity to test this 6DoF tracking to its limits, even if it meant doing cartwheels while wearing the Vive Focus. Here’s a quick recap of all the fresh details from last Friday: This Snapdragon 835 device is asking for around $600, and it features a 2, 880 x 1, 600 AMOLED display with a 110-degree field of view plus a 75 Hz refresh rate, along with a three-hour battery life, internal fan-cooling and a new white color option. Alas, there’s still no word on how this inside-out tracking mechanism works, but it appears to be derived from Qualcomm’s VR development kit . It’s been a month since my initial hands-on with the Vive Focus, so I wasn’t surprised to find the much-improved build quality on the latest batch of pre-production units. After all, the product is scheduled to ship in China next month. The plastic body now has a more refined finish, a tweaked nose rest to block more light and, more importantly, a new hinged neck support on the back strap for better weight-balancing. Instead of having to let demonstrators put the headset on me, this time I was allowed to do it all by myself, and I did so effortlessly, even with my glasses on: I just had to rest my face on to the cushion and then press the neck support inwards for auto locking. There was also a velcro strap at the top, which stopped the headset from slipping down my face. On and off, I had about one hour of total hands-on time, and at no point did I feel any discomfort, except for having to wipe the sweat off my masked face after some running around. Now that the developers have had more time with the Vive Focus, most of the ported apps I got to try performed quite well. For instance, Pillow’s Willow VR Studio’s puzzle adventure Spark of Light already had good 6DoF tracking, but this time it also didn’t trigger any over-heating warnings during my two rounds of four-minute gameplay, so I could focus on playing god and guiding the kid through the beautiful fantasy realm. Likewise with Chesstar Studios’ Great Header , which was just as stable as last time, though I quickly got bored of bouncing virtual soccer balls with my head and started doing cartwheels instead. I’d never dared to pull off a cartwheel in VR before, but thanks to the total mobility (and secure fit) of the Vive Focus, I was finally able to satisfy the gymnast inside me. To my amazement, it appears that the headset’s tracking kept up with my extreme movements, too. I’d very much like to see actual gymnasts give this a go. I quickly got bored of bouncing virtual soccer balls with my head and started doing cartwheels instead. The biggest jump in improvement I saw was on HTC Vive Studio’s very own Bowshot (from Arcade Saga), which has evolved from a sluggish prototype to a super-smooth first-person shooter. My legs didn’t have to move much; it was mainly about firing at physical computer viruses using a bow, dodging enemy fire and picking the right attack mode according to enemy formation. I quickly became addicted, mainly because it’s one of those seemingly-simple-yet-actually-challenging shooting games. My favorite demo of the lot was Kukrgame’s Mercenary: The Italian Ops , in which I had to dodge bullets and fire back at enemy soldiers inside buildings. While the Vive Focus’ Bluetooth controller only has 3DoF tracking, I quickly got used to it and still managed to enjoy this slightly odd shooting sensation. That said, the game could use more-realistic bot players: No soldier would stand out in the open while firing. Another noteworthy mention goes to Configreality’s infinite-walking VR experience, which gives the illusion of walking an infinitely long path within a confined space. In the demo, I had to walk through a series of chambers and collect large floating diamonds while dodging moving laser beams. As cool as this sounds, I quickly started noticing the moments when the software altered my path to keep me walking straight in the virtual world. It made me feel slightly nauseous, and I had to slow down. I still managed to clear at least nine chambers before the tracking suddenly went haywire — I started drifting out of the building for no reason, and we ended up having to quit the app. Apart from that hiccup plus a couple of blackspots in the room (likely due to lighting), I didn’t have too much trouble with the Vive Focus’ inside-out tracking. While it didn’t feel quite as precise as the PC-powered Vive, it still worked fine. The only time I felt sick was during the infinite maze demo, and that was the game’s problem, not the hardware’s. The headset had a few quirks: If I took the headset off in the middle of a game and walked around with it in my hand, it would take a little longer to reset the tracking before it could resume gameplay. Also, I found you shouldn’t block either front camera with your hands when you’re putting on the headset. I did have one real concern: boundaries. As much as I appreciated Vive Focus’ “world-scale” tracking, I still had to occasionally either ask the demonstrators whether I was about to hit the wall, or be told to stop before I ran out of space. According to HTC Vive’s China President Alvin Wang Graylin, the solution to this will be an optional setting to map out the size of your desired space, so when you’re reaching the limits, you’ll see a warning. Could the Vive Focus implement some sort of wall-detection feature, like the original Vive? Wang said this would be too much for the mobile chipset to handle. In contrast, the Vive gets a vast amount of processing power from a PC, plus it has fixed external base stations that help track both the users and the set boundaries . But of course, here you don’t get to enjoy the same flexibility and mobility as you’d do with the Vive Focus. Based on my latest hands-on experience, it’s safe to say that the Vive Focus continues to be a promising start for next-gen mobile VR. Better yet, the $600 price tag seems almost reasonable when compared to flagship smartphones with similar core specs (save for cellular radio). Smartphones all lack the 6DoF tracking needed for more immersive, proper VR experiences. What remains to be seen is how many more developers will join this new Vive Wave mobile VR platform (which is basically Google Daydream for China) because the hardware is only as good as the size of its ecosystem, especially when we’re looking at yet another VR platform in this young market. While current demos suggest that it isn’t too challenging to port content to Vive Wave, I’ve only seen about seven or eight good ones, which isn’t exactly a ringing endorsement from the VR developer community at the moment. But who knows, there may be more in the pipeline, and perhaps this will change when we revisit the product early next year.

Samsung Made a Bitcoin Mining Rig Out of 40 Old Galaxy S5s

An anonymous reader quotes a report from Motherboard: Samsung is starting a new “Upcycling” initiative that is designed to turn old smartphones and turn them into something brand new. Behold, for example, this bitcoin mining rig, made out of 40 old Galaxy S5 devices, which runs on a new operating system Samsung has developed for its upcycling initiative. Samsung premiered this rig, and a bunch of other cool uses for old phones, at its recent developer’s conference in San Francisco. Upcycling involves repurposing old devices instead of breaking them down for parts of reselling them. The people at Samsung’s C-Lab — an engineering team dedicated to creative projects — showed off old Galaxy phones and assorted tablets stripped of Android software and repurposed into a variety of different objects. The team hooked 40 old Galaxy S5’s together to make a bitcoin mining rig, repurposed an old Galaxy tablet into a ubuntu-powered laptop, used a Galaxy S3 to monitor a fishtank, and programed an old phone with facial recognition software to guard the entrance of a house in the form of an owl. Samsung declined to answer specific questions about the bitcoin mining rig, but an information sheet at the developer’s conference noted that eight galaxy S5 devices can mine at a greater power efficiency than a standard desktop computer (not that too many people are mining bitcoin on their desktops these days).

Amazon Fire HD 10 review (2017): A $150 tablet that’s actually good

It’s hard to get excited about an Android tablet in 2017. Samsung is still trying to take on the iPad with its premium Galaxy Tab S lineup , and there are countless slates from other companies that seem more obligatory than innovative. Mostly it boils down to one thing: Google hasn’t done much to make Android tablet-friendly. That makes Amazon’s newest Fire HD 10 tablet all the more special. It features a great 10-inch screen, it’s fast enough to run plenty of apps, and, most important, it costs just $150. Hardware From the beginning, Amazon took a different route with its Fire tablets. They use Android at their core, but they feature a custom “Fire OS” that puts all of the shopping giant’s services front and center. In a way, they’re basically digital Amazon catalogs, allowing you to easily shop and catch up on the latest Prime Video shows. While the company dabbled in the high-end arena with its Fire HDX line, it eventually shifted focus entirely to inexpensive tablets. They’re not exciting, but they’re ideal for people who want a cheap and easy-to-use slate that can run the occasional Android app. In that vein, not much has changed with the new Fire HD 10. It has the same overall design as the 2015 model, with a plastic body and large bezels around the 10.1-inch screen. Notably, there’s no aluminum case, like there was with last year’s entry , but that makes sense, since Amazon was clearly trying to cut costs. At 9.8 millimeters thick, the Fire HD 10 isn’t exactly slim, but its rounded edges make it easy to hold. It’s only a tad heavier than the 9.7-inch iPad, clocking in at 1.1 pounds. I don’t expect much from a $150 tablet, but the Fire HD 10 surprised me — first, with its sturdiness. The plastic case didn’t flex when I tried to bend it, and there weren’t any any noticeable creaking noises either. It feels like something that could take a tumble with ease. That makes it particularly well suited to children and the chronically clumsy. It’s odd that Amazon didn’t make an extra-strong “Kids Edition, ” even though it did for the smaller Fire 7 and HD 8. Those are more expensive than the standard versions, but they come with protective cases and, most important, a two-year warranty against all sorts of damage. The most immediate upgrade is the Fire HD 10’s 1080p screen (224ppi), which is a solid bump up from the 720p (1, 280 x 800–pixel) display of its predecessor. Under the hood, it packs in 2GB of RAM (twice as much as before), as well as a 1.8GHz quad-core processor, which Amazon claims is 30 percent faster than the last model’s. The tablet also includes 32GB of storage, and you can add an additional 256GB via the microSD slot. The Fire HD 10 features two stereo speakers, as well as Dolby Atmos for headphones, which helps to make surround-sound audio more immersive. Amazon also included a 2-megapixel camera on the rear, which is a laughably low resolution for a front-facing camera these days, let alone a primary shooter. There’s also a front-facing VGA (640 x 480 pixels) camera that feels like a blast from the past. It’s been more than a decade since I last saw such a low-res camera on anything. Beyond that, the HD 10’s hardware is fairly straightforward. It still charges over micro-USB — you’ll have to wait a bit longer for Amazon to jump on the USB-C bandwagon. Software While we’ve seen Alexa in the Fire HD 8 before, the new Fire HD 10 is Amazon’s first tablet to offer completely hands-free communication with its virtual assistant. Instead of pressing a button to issue commands, you can simply say “Alexa” out loud, even when the tablet is asleep. It works much like Amazon’s Echo devices, except you also get some on-screen feedback in addition to the assistant’s voice responses. Aside from the addition of hands-free Alexa, Amazon’s Fire OS hasn’t changed much. It’s still broken down into several columns: “For You, ” which directs you to Kindle and Prime Video content in your library; “Home, ” where all of your apps live; and sections for books, videos, games, apps, Audible and newsstand content. And, of course, there’s also one category dedicated to shopping on Amazon. It’s all fairly straightforward, though the huge variety of sections can be intimidating at first. In use Devindra Hardawar/Engadget I’ll admit, I typically dread testing out Amazon’s tablets. They’re not bad, especially given their low prices, but they’re much slower than the gear I normally use. Not so with the Fire HD 10. It’s the first inexpensive Amazon tablet that’s fast enough to keep up with my needs. That’s mostly because the company has finally moved beyond a paltry 1GB of RAM. But I also appreciated having some extra CPU horsepower under the hood. It didn’t matter whether I was scrolling through Twitter feeds, browsing demanding websites, playing Amazon Prime movies or hopping between apps — the Fire HD 10 handled it all without slowing down. Surprisingly, the stereo speakers sound great, even at high volumes. The tablet can even run some games decently, though it would stutter with anything graphically demanding. While the tablet has received a huge performance boost, its GPU is still underwhelming. Really, though, the biggest improvement you’ll notice in the Fire HD 10 is its 1080p screen. That might not sound very exciting these days, but it’s a significant leap for Amazon. The higher resolution makes videos and photos much clearer than before, and the improved brightness makes everything pop. It’s also sharp enough to display text clearly, which is ideal for Kindle books. Sure, the screen doesn’t hold a candle to the insanely bright OLED displays Samsung is using in the Galaxy Tab S2 and S3, but they’re also far more expensive. If you haven’t been bitten by the Amazon Echo bug yet, the Fire HD 10’s Alexa integration will give you a taste of what you’ve been missing. You can ask the virtual assistant to do things like tell you the weather, set timers and relay the latest news. But it also takes advantage of the tablet’s screen to display cards with more information. For example, when you ask about the weather, you also get a preview of what’s to come over the next few days. Alexa can also start playing a video or song on Prime services at your request — unfortunately, that doesn’t work for other platforms like Netflix. The tablet has only one microphone, but it managed to hear my voice requests most of the time, even in noisy environments. Compared with other Android tablets, Amazon’s interface feels far more refined, despite being a bit cluttered. You’re never more than a few swipes away from a new TV show to binge, a book to read or a pair of Cole Haan boots. It’s a consumption machine, for better or worse. The Fire HD 10 lasted nine hours and 45 minutes while playing a downloaded HD video on loop. That’s pretty close to Amazon’s 10-hour battery life claim. While you can install popular Android apps on the Fire HD 10, like Netflix, Evernote and Spotify, Google’s services are noticeably absent from Fire OS. That means no Gmail, no Google Maps and no Google Calendar. Of course, that’s been the case with all of Amazon’s tablets, but that doesn’t make it any less frustrating. You can, of course, use the built-in email app and Amazon’s Silk browser, but they’re no match for native Android Gmail and Chrome. There are also ways to hack the Fire HD 10 and install Google’s services, but that’s not something that’ll help mainstream users. Given just how much Amazon had to customize Android for Fire OS, there’s little chance Google would ever grant access to its apps. But since Android slates have been in a death spiral over the past few years, it’d be wise for Google to work more closely with the one company that’s built successful tablets on its platform. Let’s face it: The search giant needs to do more than just shove Android apps into Chromebooks . Pricing and the competition In addition to the standard 32GB Fire HD 10 for $150, there’s a 64GB model going for $190. You can also remove Amazon’s special-offer ads on both for an additional $15. While there are plenty of cheap Android tablets on the market, there aren’t many I’d actually recommend. Even Google has given up on its Nexus tablet lineup (a shame, because the Nexus 7 was great). Consequently, Amazon basically competes with itself when it comes to low-end slates. The new Fire HD 8 starts at $80, with 16GB of storage, and the svelte Fire 7 goes for just $50, with 8GB. If you’re worried about the portability of the HD 10, the 8-inch model might be a solid compromise. If you want something even more powerful, with a wider assortment of apps (including Google’s), then it’s worth looking at Apple’s newest iPad. It’s just $329 and features a much better screen and superior hardware. Of course, that means hopping over to iOS, but your only other alternative in the Android arena is the Galaxy Tab S2 , a two-year-old slate that still sells for $300. It has a gorgeous screen and it’s incredibly thin, but its aging hardware doesn’t seem like a good investment today. (If you find it on sale, though, it’s worth a close look.) Wrap-up The Fire HD 10 is a glimmer of hope in the barren Android tablet wasteland. It fixes everything we didn’t like about the last model, while dropping down to an incredibly low price for a 10.1-inch slate. It’s just a shame that such a well-crafted Android device can’t run Google’s services. As it stands, though, the Fire HD 10 is still the cheap slate to beat this year.

Ransomware Infects a Hotel’s Key System

An anonymous reader writes: A luxury hotel “paid “thousands” in Bitcoin ransom to cybercriminals who hacked into their electronic key system. The “furious” hotel manager says it’s the third time their electronic system has been attacked, though one local news site reports that “on the fourth attempt the hackers had no chance because the computers had been replaced and the latest security standards integrated, and some networks had been decoupled.” The 111-year-old hotel is now planning to remove all their electronic locks, and return to old-fashioned door locks with real keys. But they’re going public to warn other hotels — some of which they say have also already been hit by ransomware. UPDATE: The hotel’s managing director has clarified today that despite press reports, “We were hacked, but nobody was locked in or out” of their rooms. Read more of this story at Slashdot.

Nintendo’s Fire Emblem Heroes will launch on Android before iOS

iOS users will have to wait longer for Nintendo’s next major smartphone game release. Nintendo’s push towards smartphone gaming will continue on February 2 with the launch of Fire Emblem Heroes , a touch-only take on the company’s longtime tactical RPG series—and possibly the company’s most micro-transaction driven game yet. Like Super Mario Run before it, Fire Emblem Heroes will have a period of platform exclusivity—but in a surprise twist, that exclusivity is reversed. Android users will get first crack at Heroes on that release date, while iOS users have been told their version is coming “soon.” (For an estimate of how long the left-behind platform might have to wait, remember:  Super Mario Run has yet to launch on Android over a month after its iOS release.) During this announcement, Nintendo did not mention  Animal Crossing , the other series set to receive a smartphone port in the near future. Read 5 remaining paragraphs | Comments

Army’s first shoulder-fired “smart weapon” close to final test

Orbital ATK The XM25 is the Army’s first “smart” shoulder-fired weapon. “It launches 25mm dual-warhead, low velocity, flat trajectory ammunition designed to explode over a target,” as the Army describes it-allowing it to blow things and people up hidden behind cover. 4 more images in gallery Early next year, the US Army will begin acceptance testing of a weapon that seems like it’s straight out of Call of Duty Advanced Warfare:  the XM25 Counter Defilade Engagement System , a “smart” grenade launcher from Orbital Sciences subsidiary Orbital ATK. The XM25 is designed to be an “anti-defilade” weapon-its purpose is to allow soldiers to hit targets shielded by cover. The XM25 has a built-in “target acquisition and fire control system” that allows any soldier with basic rifleman skills to operate it effectively–the soldier points the weapon’s target selector down range, and a laser rangefinder determines how far away it is. The soldier can add additional distance to clear obstacles, and the fire control computer gives the soldier a new aiming point to put the round on target, as well as setting the fusing of the grenade in the chamber. The grenade doesn’t have to strike anything to explode, so it can detonate in the air over whatever or whoever might be hiding behind a vehicle, wall, or entrenchment. The XM25 has been in development since the middle of the last decade. Originally developed by Alliant TechSystems, which was acquired by Orbital Sciences. In 2010, the Army’s PEO Soldier program office sent prototypes of the XM25 to Afghanistan for “forward operational assessment”–use in actual combat to see how it performed. PEO Soldier’s Lt. Colonel Chris Lehner said in a post about the field tests that the “introduction of the XM25 is akin to other revolutionary systems such as the machine gun, the airplane and the tank, all of which changed battlefield tactics. No longer will our Soldiers have to expose themselves by firing and maneuvering to eliminate an enemy behind cover. Our Soldiers can remain covered/protected and use their XM25 to neutralize an enemy in his covered position. This will significantly reduce the risk of U.S. casualties and change the way we fight.” Read 2 remaining paragraphs | Comments

The next Apple TV is reportedly much more expensive

Do you recall the early days of the Apple TV , when you could expect to pay over $100 to put an Apple-powered media hub in your living room? They might come roaring back. Sources for 9to5Mac claim that the next Apple TV should cost between $149 to $199 (the final price is still up in the air) when it ships, which is reportedly sometime in October. That’s still less than the original cost when it was new, but you could be in for sticker shock if you were expecting Apple to keep the price to $99 or less . It could make the Fire TV and Roku 3 look like relative bargains, depending on how attached you are to Apple’s ecosystem. Not that such a hike would be entirely surprising, mind you. Many of the rumors swirling around Apple’s next set-top suggest that it’ll be a much more powerful device with an A8 processor, more storage, Siri voice recognition, an app store and (in recent rumors) motion control . It wouldn’t so much be a sorely overdue update as a redefinition of what the Apple TV is — instead of focusing almost exclusively on streaming video, it’d be a Shield TV-like box that can handle gaming and other tasks suited to the big screen. And if that’s too rich for your blood, you may not have to worry. The insiders say that the third-generation Apple TV will stick around, and that it’ll get the company’s long-fabled streaming TV service . You’d miss out on the app store, Siri and other features that would likely require new hardware, but you wouldn’t have to scrounge for extra cash just to see how Apple tackles streaming media in the future.
