Sony patents Vive-like tracking system, hints at wireless PSVR

Application shows Lighthouse-style set-up to counteract current light interference

Sony Interactive Entertainment has filed a patent for a new system to track virtual reality devices that's not dissimilar to that of the HTC Vive.

The patent application, spotted by CGM, outlines a device that projects a beam to determine the position of the headset with more accuracy than the PlayStation VR's current internal tracking system. It's comparable to the Vive's Lighthouse tracking system which uses beams from each of the two stations that come with the device and must be set up either side of the room.

The current PSVR tracking system relies on the PlayStation Camera picking up lights emitting from various positions on the headset itself, but since launch players have noticed that light interference can hamper the tracking, tarnishing their VR experience somewhat. The new system would allow for more accuracy, bringing PSVR closer to the likes of Vive and Oculus.

UploadVR also noticed the description int he patent application refers to a wireless connections between the headset and a computing device such as the PS4, whether via wi-fi, Bluetooth, radio frequency or other methods. While it's not confirmation, it suggests Sony may be working on a wireless version of PSVR.

As always, a patent application is no guarantee that a final product will emerge using this technology, but it does suggest a potential update to the current PlaySation VR, or perhaps a brand new version entirely.

There's a reason why most actually realized wireless VR is self contained. There's a huge amount of latency introduced which greatly contributes to motion sickness in some people. A lot can happen in 20ms. Frankly I think something like "the power of the cloud" is probably most feasible, where non-frame critical timing tasks like AIare done by a support box are probably the way these things will eventually go.

Offloading stuff to the cloud really won't make a whit of difference to the short-range wifi/bluetooth latency. More likely Sony have decided that the latency is an acceptable price to pay for untethered VR. It'll still be FAR better than any mobile VR solution relying on compass/accelerometers for tracking, and those are hugely popular. For the mass market, ease of access trumps quality of experience.

I'm saying offload to the cloud things that are high compute but not dependent on low latency, like crowd AI. The level of computing power you can stuff into the goggles will always be limited by size, weight, and battery life. Pairing that to a box that has that extra power available will make higher level experiences much more viable
