Qualcomm’s new Snapdragon 845 VRDK, a VR headset reference design for and software program builders, is now providing 6DOF controller enter with ultrasonic monitoring.

Qualcomm’s Snapdragon 845 VDRK is actually a place to begin for firms who need to construct their very own standalone VR headsets to supply to prospects; the reference headset gives quite a few choices which will be personalized to style. Options like hand-tracking and eye-tracking have made their means into the providing, and now ultrasonic monitoring for 6DOF controller enter is obtainable, as famous in a press launch by Goertek, the manufurating accomplice of the Snapdragon 845 VRDK.

Consumer headsets just like the Oculus Go, Lenovo Mirage Solo, and HTC Vive Focus are all based mostly on earlier variations of the Snapdragon VRDK, however none of them supply 6DOF controller monitoring. 6DOF controller monitoring signifies that the controller will be tracked via 3D house (similar to high-end tethered VR headsets), which ends up in a considerably extra immersive VR expertise. The aforementioned headsets solely help 3DOF controller monitoring, which suggests solely the rotation of the controller is sensed, limiting the sensation of actually having your palms in VR.

6DOF controllers on standalone headsets have been a troublesome nut to crack due to the difficulties of attaining a big sensing quantity with out exterior sensors, and due to the facility and compute constraints of cellular in comparison with PC .

While Oculus has been engaged on an optical 6DOF controller monitoring strategy on their Santa Cruz prototype, Qualcomm’s new Snapdragon VRDK hopes to resolve the issue with ultrasonic monitoring, which makes use of inaudible sound waves to triangulate the place of an object in house. The newest photographs of the reference headset present what seem like six ultrasonic emitters (and/or receivers) on the headset, three on either side. These could be used to both ship or obtain ultrasonic indicators to corresponding controllers, whereas variations in timing from every of the indicators is used to calculate place, which might seemingly be fused with rotational knowledge from an onboard IMU.

Ultrasonic monitoring will not be new by any means; we’ve seen VR trackers based mostly on the expertise lately, and the tech was employed for related functions lengthy earlier than the trendy period of VR. Pico Neo was one of many first trendy standalone headsets we’ve seen utilizing ultrasonic monitoring for 6DOF enter, although our hands-on with the headset earlier this 12 months didn’t encourage a lot confidence within the controller monitoring.

Generally talking, the capabilities of ultrasonic monitoring have been thought of inadequate as a head-tracking answer for high-end VR headsets, although hand-tracking is much less delicate to latency and accuracy, and will show efficient with the best implementation. The Pico Neo answer was developed by Chirp Microsystems, and whereas the headset relies on an earlier model of the Snapdragon VRDK, it isn’t clear if the newest reference headset is utilizing the identical system (we’ve reached out for affirmation from Goertek). The Pico Neo seems to be utilizing three front-facing emitters/receivers on the headset in comparison with six on the 845 VRDK, that are positioned on the entrance and sides of the machine; it stays to be seen what impression this might have on the controller monitoring high quality.

New standalone headsets based mostly on the Snapdragon 845 VRDK are anticipated to start out popping up within the second half of 2018, although it’ll be as much as every firm to determine in the event that they need to embrace ultrasonic 6DOF controller monitoring with their headset.
