If I'm interpreting this correctly, Sony appears to be researching a Vive-like tracking system
http://www.freepatentsonline.com/20170039959.pdf
Seems like Sony has an alternative take on the Lighthouse approach of 3D tracking.
This might be an indicator where they could take PSVR 2 in some years which would likely be on PS5 since you would have to start all over with a new PSVR ecosystem, no re-use of Move etc (a good thing imo).
This and inside-out optical tracking solutions seems like the two viable directions to go in the future. However it might be that inside-out optical tracking (no external sensors) has too many near-future hurdles for a console environment (though I think it makes a lot of sense for a fully standalone HMD product). If we detail Pros and Cons for each potential direction:
Inside-Out optical tracking
PROS:
+ No external sensors, all tech resides in headset (and console), no setup process.
CONS
- ...inside-out tracking for VR (much stricter tracking requirements than AR) has not yet been proven.
- How do you handle controller tracking? Track only when in view of headset, drift otherwise?
- If you want to go wireless: Will require 2x bandwidth compared to other tracking solutions since you would have to both receive and send a video-stream (for the console to process position). More fragile & maybe more battery draining.
Lighthouse/Vive-like tracking
PROS:
+ It works perfectly and is proven for VR today.
+ Perfect tracking of controllers no matter headset position.
+ Easier to go wireless: Only 1x bandwidth for receiving video stream.
+ Arbitrary number of devices tracked.
CONS:
- External projector(s) needed making setup more complex.
