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.

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.

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.
As I mentioned last week, my ZTE Axon 7 has just received Android 7.0 Nougat, which also unlocked Google Daydream VR. I wasn’t able to pick up Google’s VR headset at the time, but now I can, so I did, and I spent a couple of hours messing around with it.
First, I have to say I am very glad that Google made one headset (and controller) that works with all Daydream-compatible phones. That wasn’t entirely clear when I ordered my Axon 7 last summer, and I feared it would lead to a lot of waiting for my OEM to release a specific headset that may or may not be as good as any another vendor’s, especially sight unseen. I don’t really know how they properly align the screens, across all possible phones and accounting for user-error, but it seems to accept my phone perfectly without really any fiddling. Maybe it’s a simpler problem than I am envisioning, but, either way, the one viewer works with my ZTE Axon 7 -- it’s not just for the Pixel.
My second point is that the phone gets very hot, very quick. I’m sure ZTE knows about this, and the phone is designed around it, but it doesn’t just get warm, it borders on hot-to-the-touch at times. To be safe, I’m removing the case each time I insert it into the Daydream View, although the device seems to work either way. The battery does drain quickly, relative to other workloads, but a single, hour-or-so VR sitting took about 25% off (~75% remaining). Despite the heat and the quick battery drain, you will probably be done with a VR sitting before the device is, so I consider those aspects to be all-around positive.
As for the YouTube app, I’m glad that the virtual screen for standard video can be adjusted in pretty much any way. You can make it bigger or smaller with the track pad, pull it in any direction with motion controls, and adjust whether it’s flat or curved (so all points are equidistant) in the settings. If you want to lay on your back in bed and watch movies “on the ceiling”, then you can... and without holding the phone over your face while your arms go numb.
Yes, I’m speaking from experience.
As for games? Eh... about the only thing that caught my eye is maybe “Keep Talking and Nobody Explodes”. I’m pleasantly surprised it’s there, but it’s about the only thing that is. I knew there wasn’t a whole lot of apps, and that’s fine for me, but you probably shouldn’t get too excited outside of video.
Also, it’d be nice to see Google Chrome in VR. Get on that, Google! A virtual void would make a good place to keep my many, many tabs. It will apparently support WebVR content very soon, but in a “browse, click the Daydream button, mount it in the View, and put it on your head, then undo all that when you’re done” sort of way. It’d be nice to just... stay in the headset to browse.
Anywho, I have it, and those are my thoughts. It’s early, but it seems to work pretty well. I haven’t tried an Oculus Rift or an HTC Vive yet, though, so I can’t make any comparisons there.

Now that Android 7.0 Nougat is beginning to ship on phones, and the holidays are around the corner, Google is releasing accessories to support it. The Daydream View, which you can dock phones into for VR purposes, will be on sale on November 10th. The viewer will cost $79 USD, minus the phone of course, and can be purchased in the US, Canada, UK, Germany, and Australia.
Currently, the only Daydream-compatible phone is Google's Pixel. As mentioned before, Nougat is only beginning to ship on phones, and the OS is required for this feature. One thing that's not entirely clear to me, after reading several sites, is whether all Daydream-compatible phones will be able to use this specific viewer, or if some will need a different chassis. You would think that variations in attributes like screen size might complicate things, but we know it will support other, non-Pixel phones; I'm just not clear whether it's some or all.
Anyway, that concern aside, it's almost cheap enough to be a “why not?” addition to any phone that is compatible. It certainly will not put the HTC Vive PC-based VR system out of business, but I'm interested in how it works with mobile content, especially linear video, going forward.

Detailed information on Google's Daydream VR Headeset was conspicuously absent from io16. At that time it was still expected that Google was developing a VR headset to compete with the Rift and Vive which is why it seemed strange they merely mentioned it in passing. Today rumours are spreading that Google may have abandoned that particular project on favour of improving mobile VR, taking advantage of Google Cardboard one might assume. They are instead focusing on the software side, the Daydream VR platform designed to enhance VR capabilities on Android N will be improved and offered to vendors; Huawei was mentioned in the post on The Inquirer. While it is still rumour at this point it certainly makes sense to stop spending money to develop competing hardware when they can focus on improving mobile software which any Android phone could use.
"While Daydream persists, Recode said that Google has cancelled plans to create its own VR headset as it does not want to compete with Facebook, Samsung, HTC and others."
