Simply concerning the only factor we all know to date concerning the new Daydream standalone VR headsets in the works from HTC and Lenovo is that they’re… within the works. Now nevertheless we’re getting a bit extra readability concerning the hardware: each can be constructed round Qualcomm’s VR headset reference design.
Qualcomm’s ‘VRDK’ is a reference device that the corporate has positioned to behave as a basis for client electronics makers to create their very own headsets primarily based on Qualcomm’s Snapdragon VR hardware. When growing the primary prototype standalone Daydream headsets, Google primarily based their work on the Qualcomm VRDK, and, subsequently, each HTC and Lenovo’s standalone Daydream headsets can be constructed on the identical basis.
Once I got my hands on the prototype Daydream standalone headset again at Google I/O in Could, I used to be informed that the headset was utilizing year-old hardware, possible an older model of the VRDK primarily based on Qualcomm’s Snapdragon 820 chip. Qualcomm says that the HTC Vive and Lenovo standalone headsets can be constructed across the newest model of the VRDK which makes use of the considerably extra trendy Snapdragon 835 chip.
This week Qualcomm has revealed some details concerning the particular elements inside the most recent VRDK.
The primary of which is the Bosch BMX055 IMU for rotational monitoring, together with the basic trio of accelerometer, gyroscope, and magnetometer. To attain positional monitoring, the VRDK options on-board cameras that are backed by the OmniVision OV9282 international shutter picture sensor which might seize 1,280 x 800 pictures at 120Hz, or 180Hz at 640 x 480. OmniVision particularly positions the OV9282 picture sensor as preferrred for VR headsets because of the low latency.

And whereas OmniVision and Bosch make the important elements that can be used for inside-out positional monitoring on the Daydream standalone headsets, it’s our understanding that the spectacular ‘WorldSense’ tracking algorithm is wholly developed by Google.
Between documentation and our discussions with Qualcomm we count on to see each the HTC and Lenovo Daydream headsets include a 2,560 x 1,440 AMOLED display at 90Hz, although the producer is unclear. As for lenses, details are skinny, however to date we’ve seen non-Fresnel lenses on the VRDK which Qualcomm says have a 100 diploma area of view.
Presumably any of the elements within the VRDK reference design could possibly be tweaked or swapped for various elements, although with how rapidly HTC and Lenovo are bringing their Daydream standalone headsets to promote it isn’t clear how a lot they’d wish to rock the boat when it comes to important hardware. I’m no knowledgeable relating to the method of turning a reference design right into a business product, however I enterprise to guess that the display and lenses could be among the many elements probably to be tweaked since they’re main contributors to the end-user experience.
With comparable (if not equivalent) elements inside these headsets, one large query is what’s going to differentiate them. Initially it appears the variations will largely be exterior (much like two Android smartphones primarily based on the identical Snapdragon chip).
The teaser pictures we’ve seen for every headset present two very completely different approaches to the head-mount. Curiously, neither design confirmed to date consists of on-board headphones (which is unquestionably a scale-tipping function). Further equipment—which HTC has been fairly aggressive about for the Vive desktop headset—may be an early differentiator.
As standalone VR headsets mature in each content material and hardware, we count on to differentiation between standalone Daydream headsets to develop, particularly as extra hardware producers enter the sector.
