Qualcomm has put forward steady work on creating the vibrant hardware ecosystem for mobile VR to facilitate broad adoption of wireless, dedicated head mounted displays. Though the value of Samsung’s Gear VR and Google’s Daydream View cannot but overstated in moving the perception of consumer VR forward, the need to utilize your smart phone in a slot-in style design has its limitations. It consumes battery that you may require for other purposes, it limits the kinds of sensors that the VR system can utilize, and creates a sub-optimal form factor in order to allow for simple user installation.
The Qualcomm Snapdragon 835 VR Reference Device
Qualcomm created the first standalone VR HMD reference design back in early 2016, powered by the Snapdragon 820 processor. Google partnered with Qualcomm at I/O to create the Daydream standalone VR headset reference design with the updated Snapdragon 835 Mobile Platform at its core, improving performance and graphical capability along the way. OEMs like Lenovo and HTC have already committed to Daydream standalone units, with Qualcomm at the heart of the hardware.
Qualcomm Technologies recently announced a HMD Accelerator Program (HAP) to help VR device manufacturers quickly develop premium standalone VR HMDs. At the core of this program is the standalone VR HMD reference design. It goes beyond a simple prototype device, offering a detailed reference design that allows manufacturers to apply their own customizations while utilizing our engineering, design, and experience in VR. The reference design is engineered to minimize software changes, hardware issues, and key component validation.

As part of this venture, and to continue pushing the VR industry forward to more advanced capabilities like XR (extended reality, a merger of VR and AR), Qualcomm is announcing agreements with key component vendors aiming to tighten and strengthen the VR headset ecosystem.

Ximmerse has built a high-precision and drift-free controller for VR applications that offers low latency input and 3DoF (3 degrees of freedom) capability. This can “provide just about any interaction, such as pointing, selecting, grabbing, shooting, and much more. For precise 6 DoF positional tracking of your head, tight integration is required between the sensor fusion processing (Snapdragon) and the data from both the camera and inertial sensors.”
Bosch Sensortec has the BMX055 absolute orientation sensor that performs the function that its name would imply: precisely locating the user in the real world and tracking movement via accelerometer, gyroscope, and magnetometer.
Finally, OmniVision integrates the OV9282 which is a 1MP high speed shutter image sensor for feature tracking.
These technologies, paired with the work Qualcomm has already done for the Snapdragon 835 VR Development Kit, including on the software side, is an important step to the growth of this segment of the market. I don’t know of anyone that doesn’t believe standalone, wireless headsets are the eventual future of VR and AR and the momentum created by Qualcomm, Google, and others continues its steady pace of development.
Introduction and Design
In case you have not heard by now, Pixel is the re-imagining of the Nexus phone concept by Google; a fully stock version of the Android experience on custom, Google-authorized hardware - and with the promise of the latest OS updates as they are released. So how does the hardware stack up? We are late into the life of the Pixel by now, and this is more of a long-term review as I have had the smaller version of the phone on hand for some weeks now. As a result I can offer my candid view of the less-covered of the two Pixel handsets (most reviews center around the Pixel XL), and its performance.
There was always a certain cachet to owning a Nexus phone, and you could rest assured that you would be running the latest version of Android before anyone on operator-controlled hardware. The Nexus phones were sold primarily by Google, unlocked, with operator/retail availability at times during their run. Things took a turn when Google opted to offer a carrier-branded version of the Nexus 6 back in November of 2014, along with their usual unlocked Google Play store offering. But this departure was not just an issue of branding, as the price jumped to a full $649; the off-contract cost of premium handsets such as Apple’s iPhone. How could Google hope to compete in a space dominated by Apple and Samsung phones purchased by and large with operator subsidies and installment plans? They did not compete, of course, and the Nexus 6 flopped.
Pixel, coming after the Huawei-manufactured Nexus 6p and LG-manufactured Nexus 5X, drops the “Nexus” branding while continuing the tradition of a reference Android experience - and the more recent tradition of premium pricing. As we have seen in the months since its release, the Pixel did not put much of a dent into the Apple/Samsung dominated handset market. But even during the budget-friendly Nexus era, which offered a compelling mix of day-one Android OS update availability and inexpensive, unlocked hardware (think Nexus 4 at $299 and Nexus 5 at $349), Google's own phones were never mainstream. Still, in keeping with iPhone and Galaxy flagships $649 nets you a Pixel, which also launched through Verizon in an exclusive operator deal. Of course a larger version of the Pixel exists, and I would be remiss if I did not mention the Pixel XL. Unfortunately I would also be remiss if I didn't mention that stock for the XL has been quite low with availability constantly in question.
The Pixel is hard to distinguish from an iPhone 7 from a distance (other than the home button)

The Register has heard the names of the three vendors that Qualcomm will tap to produce Win10 machines running on their chips. The winners are as expected, Lenovo, HP and ASUS will be licensed to sell these mysterious low powered and extremely mobile devices. Unfortunately that is pretty much all we know, there were no dates nor models announced by Qualcomm or its new partners. We can certainly speculate that these devices will be as thin as the battery will allow, the cooling solution for a Snapdragon can be extremely compact, assume that you will not see any wired NICs as the RJ-45 jack would be thicker than the device. We should be able to assume their will be a headphone jack at least.
"The chipmaker says the three vendors will be making PCs that will sport its Snapdragon 835 SoC (system-on-chip) and its X16 LTE chipset for wireless broadband connectivity. Qualcomm says all of the models will be fanless and will offer all-day battery life."

Back in December of 2016, Qualcomm and Microsoft announced a partnership to bring Windows to platforms based on the Snapdragon platform. Not Windows RT redux, not Windows mobile, not Windows Mini, full blown Windows with 100% application support and compatibility. It was a surprising and gutsy move after the tepid response (at best) to the ARM-based Windows RT launch several years ago. Qualcomm and Microsoft assure us that this time things are different, thanks to a lot of learning and additional features that make the transition seamless for consumers.
The big reveal for this week is the initial list of partners that Qualcomm has brought on board to build Windows 10 system around the Snapdragon 835 Mobile Platform. ASUS, HP, and Lenovo will offer machines based around that SoC, though details on form factors, time frames, pricing and anything else you WANT to know about it, is under wraps. These are big time names though, leaders in the PC notebook space, and I think their input to the platform is going to be just as valuable as them selling and marketing it. HP is known for enterprise solutions, Lenovo for mass market share, and ASUS for innovative design and integration.
(If you want to see an Android-based representation of performance on a mobile-based Snapdragon 835 processor, check out our launch preview from March.)
Also on the show floor, Qualcomm begins its marketing campaign aimed to show the value that Snapdragon offers to the Windows ecosystem. Today that is exemplified in a form factor difference comparing the circuit board layout of a Snapdragon 835-based notebook and a “typical” competitor machine.
Up top, Qualcomm is showing us the prototype for the Windows 10 Snapdragon 835 Mobile Platform. It has a total area of 50.4 cm2 and just by eyeballing the two images, there is a clear difference in scope. The second image shows only what Qualcomm will call a “competing commercial circuit board” with an area of 98.1 cm2. That is a decrease in PCB space of 48% (advantage Qualcomm) and gives OEMs a lot of flexibility in design that they might not have had otherwise. They can use that space to make machines thinner, lighter, include a larger battery, or simply to innovate outside the scope of what we can imagine today.

During the Google I/O keynote, Google and Qualcomm announced a partnership to create a reference design for a standalone Daydream VR headset using Snapdragon 835 to enable the ecosystem of partners to have deliverable hardware in consumers’ hands by the end of 2017. The time line is aggressive, impressively so, thanks in large part to the previous work Qualcomm had done with the Snapdragon-based VR reference design we first saw in September 2016. At the time the Qualcomm platform was powered by the Snapdragon 820. Since then, Qualcomm has updated the design to integrate the Snapdragon 835 processor and platform, improving performance and efficiency along the way.
Google has now taken the reference platform and made some modifications to integrate Daydream support and will offer it to partners to show case what a standalone, untethered VR solution can do. Even though Google Daydream has been shipping in the form of slot-in phones with a “dummy” headset, integrating the whole package into a dedicate device offers several advantages.
First, I expected the free standalone units to have better performance than the phones used as a slot-in solution. With the ability to tune the device to higher thermal limits, Qualcomm and Google will be able to ramp up the clocks on the GPU and SoC to get optimal performance. And, because there is more room for a larger battery on the headset design, there should be an advantage in battery life along with the increase in performance.
The Qualcomm Snapdragon 835 VR Reference Device
It is also likely that the device will have better thermal properties than those using high smartphones today. In other words, with more space, there should be more area for cooling and thus the unit shouldn’t be as warm on the consumers face.
I would assume as well that the standalone units will have improved hardware over the smartphone iterations. That means better gyros, cameras, sensors, etc. that could lead to improved capability for the hardware in this form. Better hardware, tighter and more focused integration and better software support should mean lower latency and better VR gaming across the board. Assuming everything is implemented as it should.
The only major change that Google has made to this reference platform is the move away from Qualcomm’s 6DOF technology (6 degrees of freedom, allowing you to move in real space and have all necessary tracking done on the headset itself) and to Google calls WorldSense. Based on the Google Project Tango technology, this is the one area I have questions about going forward. I have used three different Tango enabled devices thus far with long-term personal testing and can say that while the possibilities for it were astounding, the implementations had been…slow. For VR that 100% cannot be the case. I don’t yet know how different its integration is from what Qualcomm had done previously, but hopefully Google will leverage the work Qualcomm has already done with its platform.
Google is claiming that consumers will have hardware based on this reference design in 2017 but no pricing has been shared with me yet. I wouldn’t expect it to be inexpensive though – we are talking about all the hardware that goes into a flagship smartphone plus a little extra for the VR goodness. We’ll see how aggressive Google wants its partners to be and if it is willing to absorb any of the upfront costs with subsidy.
Let me know if this is the direction you hope to see VR move – away from tethered PC-based solutions and into the world of standalone units.

Recently, to prepare for a long plane flight I bought a pair of Sony MDR-1000X Bluetooth noise canceling headphones. While I won't get into the specifics of these headphones other than that I have been really satisfied with them, when I returned from my trip I wanted to start using them at the office.
Seemingly that would be easy, as these headphones feature a 3.5mm input, but I am frequently walking around the office and I wanted to fully utilize the wireless features. While I could have just used any Bluetooth adapter compatible with Windows, I wanted to test out one of the features of these headphones — AptX technology.
AptX is an alternate Bluetooth audio codec from Qualcomm which aims to feature higher audio quality. Sebastian took a look at a pair of AptX-enabled headphones earlier this year, and I have wanted to check out the technology ever since.
After receiving the USB adapter, I first installed the CSR Harmony software from the Azio website. This is a piece of software that sits on top of the Windows Bluetooth Stack and enabled advanced Bluetooth features, including AptX, on certain Bluetooth chipsets.
Once the software was installed, I plugged in the device and found a new Bluetooth icon sitting in my Windows tray.
From here, you can simply right click the icon and search for a new Bluetooth device.
Once I put the headphones into pairing mode I was able to pair to them successfully.
And, that's it! Once you are successfully paired to an AptX device, you should see this popup from the Windows tray confirming that AptX is working. From here, you can use the headphones just like you would with any Windows audio playback device.
This certainly isn't a review of AptX audio quality, I will defer to Sebastian's analysis for that in which he calls the headphones he tested "audiophile-approved Bluetooth."
For a $12 investment, it seems like a no-brainer for users who already have an AptX-enabled device that they use on their smartphone.

Today Qualcomm took the covers off of an update to the Snapdragon 600 family of processors, now known as mobile platforms. The Snapdragon 660 and 630 Mobile Platforms are important products in the company’s portfolio as they address a larger segment of the consumer market than the premium-tier Snapdragon 800 while still offering performance and feature sets above the budget segments of the 400s. The Snapdragon 820 and 835 traditionally get all of the attention from media, the 600-series is at the heart of popular devices like the Sony Xperia X, Asus Zenfone 3 Ultra, HTC 10 Lifestyle and over 1000 more designs.
The biggest changes to both new platforms come in the form of LTE connectivity and GPU performance. In a bid to bring previously unseen capabilities to the 600-series of solutions, Qualcomm has taken the Snapdragon X12 LTE modem that shipped with the Snapdragon 820/821 SoC and integrated it on both the 660 and 630. This creates mainstream mobile platforms that can run Cat 12/13 modems and speeds as high as 600 Mbps downstream (3x carrier aggregation) and 150 Mbps upstream (2x carrier aggregation).
That is a significant move and should result in a massive amount of high speed devices saturating the market (and carriers’ networks) starting later this year. Along with that higher performance comes the same X12 feature set that we saw with Snapdragon 820/821 including adaptive antenna tuning capability (TruSignal) and dynamic signal quality adjustments for power efficiency optimizations.
The GPU performance of both the Snapdragon 660 and 630 get a boost over the previous competitors (653 and 626 respectively) though they do so with different Adreno implementations. The SD 660 uses the Adreno 512 GPU that offers up to 30% better performance compared to the Adreno 510 used on the SD 650 series. While we don’t have details yet on where that advantage comes from (clocks or core improvements), I have a feeling that much of it comes from improved frequencies. The Snapdragon 630 uses the Adreno 508 GPU, compared to the 506 from the SD 626 processor, and also claims to have a 30% performance advantage over the previous generation.

Qualcomm and Apple are already at loggerheads over the possible dirty trick played in the iPhone7 to ensure that Intel powered iPhone models performed the same as the ones with Qualcomm inside. Slashdot and other sources have reported on a somewhat related feud taking place, which has lead Qualcomm to reach out to the US based ITC to block the import of iPhones into the US. It seems that last month Apple decided not to pay Qualcomm royalties on their phone sales, which is owed due to core patents Qualcomm holds on mobile communications chips. Apple's defence is the fact that Qualcomm gets a cut even in devices without a single Qualcomm component while Qualcomm points out the it is their patents which generate the fee, not their hardware.
It will be interesting in this current environment to see how the US based Qualcomm fares against Apple and their products, which are made in Asia.
"Qualcomm is preparing to ask the International Trade Commission to stop the iPhone, which is built in Asia, from entering the country, threatening to block Apple's iconic product from the American market in advance of its anticipated new model this fall, according to the person, who asked not to be identified because the discussions are private."

Qualcomm have provided an updated estimate for when we might expect to see Windows 10 running on Snapdragon 835 devices, moving it very close to the end of the second half of 2017. Having a product launch in December is risky if Qualcomm had hoped to see sales for the holiday season, especially for a type of product we have not seen since Microsoft released ARM powered Surface devices. It is possible that the price may be attractive enough to entice some users into purchasing the devices but we likely won't see much action until the beginning of 2018. The Register could not glean any more information beyond the updated release date from the call, we are still somewhat in the dark as to what Snapdragon powered Win 10 devices we will see.
"But in last week's Q2 2017 earnings call, CEO Steve Mollenkopf said “Our Snapdragon 835 is expanding into Mobile PC designs running Windows 10, which are scheduled to launch in the fourth calendar quarter this year.”
